<p class="wp-block-paragraph">Apollo has always worked on the difficult middle layer between backend systems and the clients that need to access them, from the early Meteor days through GraphQL’s origins as a way to fetch data for web and mobile apps, and now as the layer that connects AI agents to the systems they need to access in order to do real work. If you own a GraphQL implementation, or you are weighing how your API strategy fits into your AI roadmap, this is where the practical patterns get worked out in public.</p>

<p class="wp-block-paragraph">Your APIs were built for apps. What happens when agents want in? These five speakers have already shipped an answer, and they’ll show their work. Stay tuned for more speakers to be announced soon.</p>



<ul class="wp-block-list">
<li><a href="https://www.linkedin.com/in/jonathanwondrusch/">Jonathan Wondrusch</a>, Staff Software Engineer at Block, argues your company already has a graph, hiding in Confluence pages and a hundred half-documented REST endpoints. He shows how to build an API schema that ships product to customers and becomes the context layer your agents reason against. The surprise is that it makes the business legible to itself.</li>



<li><a href="https://www.linkedin.com/in/clarice-abreu/">Clarice Abreu</a>, Senior Software Engineer at Brex, opened GraphOS and found 35% of their federated graph was dead code. Rather than spend months cleaning 60+ subgraphs by hand, she built an agent that deletes, validates, and opens the PR. It has removed over 100,000 lines, and not one customer noticed.</li>



<li><a href="https://www.linkedin.com/in/gijs-martens/">Gijs Martens</a>, Platform Engineer, and <a href="https://www.linkedin.com/in/bartvanlakwijk/">Bart van Lakwijk</a>, Manager Web Platform at Coolblue, routed all production traffic through their graph in week one. The cutover was the easy part. Winning over a &#8220;just do it&#8221; business meant treating the graph as a utility, not a religion, and never blocking a team. No mandate. The graph sold itself.</li>



<li><a href="https://www.linkedin.com/in/sgorla/">Sharon Gorla</a>, Lead Engineer at Starbucks, has a rule for what survives a rewrite: business semantics and shared contracts, never implementation patterns. As coding agents rebuild whole systems, the gap people miss isn&#8217;t MCP or agent frameworks. It&#8217;s alignment. Clients come and go. Shared nouns and verbs are the durable layer.</li>
</ul>

<p class="wp-block-paragraph">Organizations are often pulled in opposing directions: deploying agents quickly vs. keeping control over what they can do. Teams that move fast often hand agents broad access and lose visibility. Teams that lock things down slow every project to a crawl. Summit 2026 is built around a different premise: speed and control are not a tradeoff when the graph sits between your agents and your systems.</p>



<p class="wp-block-paragraph">A self-describing graph gives agents declared, scoped access to exactly the tools they need and nothing more. It reduces token costs by handing agents the right context for each action, enforces field-level security, and improves success rates by making your existing APIs discoverable. The sessions show how teams are already doing this in production.</p>



<h2 class="wp-block-heading"><a href="#what-youll-learn" aria-hidden="true" class="aal_anchor" id="what-youll-learn"><svg aria-hidden="true" class="aal_svg" height="16" version="1.1" viewBox="0 0 16 16" width="16"><path fill-rule="evenodd" d="M4 9h1v1H4c-1.5 0-3-1.69-3-3.5S2.55 3 4 3h4c1.45 0 3 1.69 3 3.5 0 1.41-.91 2.72-2 3.25V8.59c.58-.45 1-1.27 1-2.09C10 5.22 8.98 4 8 4H4c-.98 0-2 1.22-2 2.5S3 9 4 9zm9-3h-1v1h1c1 0 2 1.22 2 2.5S13.98 12 13 12H9c-.98 0-2-1.22-2-2.5 0-.83.42-1.64 1-2.09V6.25c-1.09.53-2 1.84-2 3.25C6 11.31 7.55 13 9 13h4c1.45 0 3-1.69 3-3.5S14.5 6 13 6z"></path></svg></a><strong>What you&#8217;ll learn</strong></h2>



<p class="wp-block-paragraph">The agenda is organized around four themes that map to the decisions facing platform and AI teams right now.</p>



<ul class="wp-block-list">
<li><strong>Agent infrastructure.</strong> Design the governed entry point between agents and enterprise systems. Build a context layer that improves task success rates while keeping costs down.</li>



<li><strong>Governance and security.</strong> Manage agent identity, start from zero-rights defaults, enforce field-level access policies, and handle credentials in a single layer. Give both developers and non-developers a trusted platform to build on.</li>



<li><strong>Agentic API access.</strong> Connect REST APIs, SQL data sources, MCP servers, and third-party systems into your context layer, whether or not they already live in your graph.</li>



<li><strong>GraphQL and GraphOS.</strong> For teams running GraphQL in production today: the latest in Apollo Federation, Apollo Router optimization, schema governance, Apollo Connectors, and the Apollo MCP Server.</li>

<p class="wp-block-paragraph">Summit draws platform engineers, AI infrastructure leads, developers, and technical leaders who are building API infrastructure for both applications and agents. It is also where the broader GraphQL community gathers, including the people who maintain the specifications and tools the industry runs on. You will leave with patterns you can apply and a set of peers solving the same problems.</p>

Apollo Summit 2026: Turn Your API Platform Into Your AI Platform


<p class="wp-block-paragraph">We’re excited to announce Apollo Kotlin 5 is now available.</p>



<p class="wp-block-paragraph">Apollo Kotlin 3 was a full rewrite of Apollo Android for Kotlin multiplatform. Apollo Kotlin 4 reworked error handling, introduced the Apollo IDE plugin and semantic nullability.&nbsp;</p>



<p class="wp-block-paragraph">Apollo Kotlin 5 is <a href="https://goldenpath.graphql.org/">GraphQL Golden Path</a> ready, comes with a <a href="https://www.apollographql.com/blog/the-new-apollo-kotlin-normalized-cache">new normalized cache</a>, a rework of the Gradle plugin, new compiler plugins APIs, agent skills, <code class="" data-line="">linuxX64</code>&nbsp; and <code class="" data-line="">watchosDeviceArm64</code> targets and more.</p>



<p class="wp-block-paragraph">If you’re currently using Apollo Kotlin 4, you should feel right at home with Apollo Kotlin 5. Most APIs are untouched. For the others, read the<a href="https://www.apollographql.com/docs/kotlin/v5/migration/5.0"> migration guide</a> for details.</p>



<p class="wp-block-paragraph">For a comprehensive list of all changes, please review the <a href="https://github.com/apollographql/apollo-kotlin/releases/tag/v5.0.0">full changelog</a> or read on for a brief summary of the key updates.</p>

<p class="wp-block-paragraph">Apollo Kotlin aims to support the latest version of the <a href="https://spec.graphql.org/draft/">GraphQL draft specification</a>. Making a change to the specification draft is a long and near-irreversible process. Yet experimentation matters: it gives the community confidence that proposed changes are sound before they ship.</p>



<p class="wp-block-paragraph">For this reason, Apollo Kotlin 5 supports a number of experimental <a href="https://rfcs.graphql.org/">GraphQL RFCs</a>:</p>



<ul class="wp-block-list">
<li><a href="https://github.com/graphql/graphql-spec/pull/1081">Fragment arguments</a></li>



<li><a href="https://github.com/graphql/graphql-spec/pull/1163">Service capabilities</a></li>



<li><a href="https://specs.apollo.dev/incremental/v0.2/">Incremental 0.2</a> protocol for @defer and @stream&nbsp;</li>



<li><a href="https://github.com/graphql/graphql-spec/pull/1163">onError request parameter</a></li>



<li><a href="https://github.com/graphql/graphql-spec/issues/566">Directives on directives</a></li>



<li><a href="https://github.com/graphql/graphql-wg/blob/main/rfcs/SchemaCoordinates.md">Schema coordinates</a></li>
</ul>



<p class="wp-block-paragraph">Make sure to join an <a href="https://github.com/graphql/graphql-wg/">upcoming working group</a> and share feedback if you’re using any of these.</p>

<p class="wp-block-paragraph">The Gradle plugin now uses <a href="https://github.com/gradleup/gratatouille">Gratatouille classloader isolation</a>, instead of <a href="https://github.com/GradleUp/gr8">GR8 relocation</a> previously. This makes the plugin more robust and easier to debug.</p>



<p class="wp-block-paragraph">Apollo Kotlin 5 uses KGP 2.3, with 2.1 compatibility for JVM and Android consumers. Native and JS consumers must compile with KGP 2.3+.</p>



<p class="wp-block-paragraph">If you are using Apollo Kotlin with AI agents, the <a href="https://github.com/apollographql/skills/tree/main/skills/apollo-kotlin">Apollo Kotlin agent skill</a> is now available. Agents can use it to discover the Apollo Kotlin best practices.</p>

<p class="wp-block-paragraph">Most of the runtime APIs as well as the package name are unchanged. If your build has no Apollo deprecation warnings on v4, the upgrade should require minimal changes.</p>



<p class="wp-block-paragraph">The main breaking changes are in experimental Data Builders and Apollo Compiler Plugins.</p>

Apollo Kotlin 5 Is Now Available

10 Years of GraphQL Celebrated at GraphQLConf 2025

MCP Server Builder Drop: July Highlights from San Francisco and New York


<p class="wp-block-paragraph">Writing resolvers for REST APIs has been a rite of passage for developers working with GraphQL, but what if there were an easier way? Meet Apollo Connectors.&nbsp;&nbsp;</p>



<p class="wp-block-paragraph">As shown in Figure 1, Apollo Connectors mitigate the need to write code that connects to and returns data from REST APIs, reducing code surface area and time so you can focus on the business problem you&#8217;re trying to solve.</p>

<p class="wp-block-paragraph"><em>Figure 1: Data flow showing Apollo Connector for REST APIs</em></p>



<p class="wp-block-paragraph">In this article, we will walk through a React client web application that leverages the Apollo GraphQL client to call a public <a href="https://currencyapi.com/">CurrencyAPI</a> web service using the REST API Apollo Connector for REST APIs.&nbsp; A screenshot of the UI is seen in the following figure:&nbsp;&nbsp;</p>

<p class="wp-block-paragraph"><em>Figure 2: Screenshot of the Currency Converter</em></p>



<p class="wp-block-paragraph">Under the covers, the React app uses the GraphQL Client as usual and issues the query statement.&nbsp; There are no changes there.&nbsp; On the backend, you simply define the GraphQL schema file and that’s it. There is no need to create resolvers to fetch the data from the REST API.&nbsp; In the following sections, you will learn how to set up and configure the Apollo Connector for REST APIs.</p>

<p class="wp-block-paragraph">In this article we will use a third party service called CurrencyAPI to fetch real-time currency exchange rates.&nbsp; At the time of this writing (Nov 2024), CurrencyAPI offers a free API key.&nbsp; If you wish to follow along, create an API key from <a href="https://currencyapi.com/">https://currencyapi.com/</a> and copy it down, as you will need it later.</p>



<p class="wp-block-paragraph">You will also need an Apollo account and the latest version of Apollo Rover CLI.&nbsp; See sections 1 and 2 of the following Apollo Connector tutorial for installation instructions:</p>

<p class="wp-block-paragraph">At the time of this writing, Apollo Connectors is in preview with an anticipated general availability in early 2025.&nbsp; This blog will be updated as this feature evolves.</p>



<p class="wp-block-paragraph">Now, we are ready to configure Apollo Studio and obtain our API Key.&nbsp; Navigate to <a href="http://studio.apollographql.com/?_gl=1*tm0r8z*_gcl_aw*R0NMLjE3MzE3MDM4ODQuQ2owS0NRaUFfOXU1QmhDVUFSSXNBQmJNU1BzRm5OM1NIXzRWQWN2VHJGRFBrQkctcVltVk9ncU1iLUJjczh4YkpBOVlUZzFGQ3MyWngwZ2FBaHBfRUFMd193Y0I.*_gcl_au*MTM2NzI4NDM4Ny4xNzMwMjIwNjQ0">Apollo Studio</a> and click “Create a new Graph.”&nbsp; In the “Publish your schema using Federation” dialog, you will see toward the bottom the API Key to be used with Rover.</p>



<p class="wp-block-paragraph">Below is a sample:</p>



<pre class="wp-block-prismatic-blocks"><code class="language-shell-session" data-line="">APOLLO_KEY=service:Currency-02wxjh:xxxxxxxxxxxxxxx \

<p class="wp-block-paragraph">Copy the value for <code class="" data-line="">APOLLO_KEY</code>.&nbsp; Open the <code class="" data-line="">rover-dev.md file</code> and update the section with your personalized <code class="" data-line="">APOLLO_KEY</code>.&nbsp; Copy the service name to <code class="" data-line="">APOLLO_GRAPH_REF</code> and save the file.</p>



<p class="wp-block-paragraph">Next, update the <code class="" data-line="">router-config.yaml</code> file and replace the placeholders “&lt;&lt;REPLACE&gt;&gt;” with the API Key you obtained from currencyAPI and save this file.</p>

<p class="wp-block-paragraph">A note about <code class="" data-line="">router-config.yaml</code>:&nbsp; In this example, we are launching a react client on the same machine as Rover.&nbsp; Since these are operating on different ports, the client on localhost:4000 and Rover on localhost:3000, the server needs to address CORS (Cross origin resource sharing).&nbsp; To do this, we added the following configuration to the <code class="" data-line="">router-config.yaml </code>file:</p>



<pre class="wp-block-prismatic-blocks"><code class="language-yaml" data-line="">cors:
  allow_any_origin: true</code></pre>

<p class="wp-block-paragraph">This is all that is needed for your Apollo Server to connect to a REST API, no extra resolver code!&nbsp; Looking at the GraphQL query, you’ll see an <code class="" data-line="">@link</code> statement referencing Apollo Connector.</p>



<pre class="wp-block-prismatic-blocks"><code class="language-graphql" data-line="">@link(
  url: &quot;https://specs.apollo.dev/connect/v0.1&quot;
  import: [&quot;@source&quot;, &quot;@connect&quot;]
)</code></pre>



<p class="wp-block-paragraph">Here, we are importing the <code class="" data-line="">@source</code> and <code class="" data-line="">@connect</code> directives.&nbsp; The <code class="" data-line="">@connect</code> requires additional configuration parameters such as the details about the HTTP request, any headers, and a parameter called “selection” which filters the data from the REST API results.&nbsp; Here is the <code class="" data-line="">currencyList</code> field in our example:</p>



<pre class="wp-block-prismatic-blocks"><code class="language-graphql" data-line="">  &quot;A list of currencies&quot;
  currencyList: [Currency]
    @connect(
      source: &quot;v1&quot;
      http: { GET: &quot;/currencies&quot; }
      selection: &quot;&quot;&quot;
        data-&gt;entries {
          symbol: key
          name: value.name
        }
      &quot;&quot;&quot;
    )</code></pre>



<p class="wp-block-paragraph">In this query, the Apollo Connector will use the base url defined in the <code class="" data-line="">@link</code> and append the string defined as part of the HTTP request type in this case is GET.&nbsp; Since our currencyAPI endpoint requires an authentication header, we add the <strong>headers</strong> field and add a key-value pair referencing the API Key and value we defined earlier in the <code class="" data-line="">router-config.yaml </code>file.&nbsp; Next, we need to tell the connector what data to extract from the API results.&nbsp; We define this in the <strong>selection</strong> parameter.</p>



<pre class="wp-block-prismatic-blocks"><code class="language-perl" data-line="">data-&gt;entries {
  symbol: key
  name: value.name
}</code></pre>



<p class="wp-block-paragraph">For reference, the data that returns from the CurrencyAPI is similar to the following:</p>



<pre class="wp-block-prismatic-blocks"><code class="language-json" data-line="">{
  &quot;data&quot;: {
    &quot;AED&quot;: {
      &quot;symbol&quot;: &quot;AED&quot;,
      &quot;name&quot;: &quot;United Arab Emirates Dirham&quot;,
      &quot;symbol_native&quot;: &quot;د.إ&quot;,
      &quot;decimal_digits&quot;: 2,
      &quot;rounding&quot;: 0,
      &quot;code&quot;: &quot;AED&quot;,
      &quot;name_plural&quot;: &quot;UAE dirhams&quot;,
      &quot;type&quot;: &quot;fiat&quot;,
      &quot;countries&quot;: [
        &quot;AE&quot;
      ]
    },
    ...
  }
}</code></pre>



<p class="wp-block-paragraph">For our client we want to return just the symbol and name of each of the currencies.&nbsp; Since our return result has all our data under the “data” field, we start with data and iterate through each subdocument using the <strong>entities</strong> keyword.&nbsp; For each of these <strong>entities,</strong> we return the key, which in this example result is “AED” and add that value to a “symbol” field.&nbsp; We give the field “name” the value of the name field in the result. For a complete discussion and more examples of selection parameters, see the <a href="https://www.apollographql.com/docs/graphos/schema-design/connectors/selection">online documentation</a>.</p>

<p class="wp-block-paragraph"><em>Matt DeBergalis, Founder and CTO, Apollo GraphQL</em></p>



<p class="wp-block-paragraph">Forget what you’ve heard about GraphQL – it’s not a REST alternative, graph database, or just for front-end developers. GraphQL is about combining the APIs you already have.</p>



<p class="wp-block-paragraph">In this talk, you’ll learn how a federated GraphQL architecture brings a platform approach to API composition, where it fits into the API stack, and what is coming next to help teams build tomorrow’s AI products and experiences on today’s APIs.</p>

<p class="wp-block-paragraph">GraphQL streamlines data flow between clients and services, acting as the composition layer in the middle. As businesses strive for scalable and maintainable solutions as their services grow, a federated GraphQL API is becoming the go-to architecture to meet these evolving demands.&nbsp;</p>



<p class="wp-block-paragraph">If you&#8217;re searching for helpful beginner resources to dive into GraphQL and Apollo Federation, we&#8217;ve got you. <a href="https://www.apollographql.com/tutorials/">Odyssey</a> is Apollo&#8217;s official learning platform, where you can boost your developer skills with hands-on GraphQL tutorials and trainings.</p>



<p class="wp-block-paragraph">Over the past year, Apollo’s Education team has helped close to 40,000 learners on their GraphQL learning journey, starting with JavaScript and Apollo Server implementations.&nbsp;</p>



<p class="wp-block-paragraph">Because GraphQL&#8217;s potential stretches far beyond the JavaScript realm, we&#8217;ve expanded our curriculum to support three new languages: Java, .NET (C#) and TypeScript.</p>

<p class="wp-block-paragraph">There’s been a lot of talk recently about the pros and cons of introspection, and one of the biggest reasons to disable it is to hide features you don’t want users to know about (e.g., before a new product launches). In <a rel="noreferrer noopener" href="https://engineering.hashnode.com/keep-parts-of-your-graphql-introspection-query-hidden" target="_blank">a recent blog post</a>, Florian Fuchs at HashNode shared how they hide only certain schema pieces from introspection using a custom directive and plugin with Apollo Server.

Apollo Changelog: April 3, 2023


<p class="wp-block-paragraph">Let’s consider the core promise of GraphQL:</p>



<p class="wp-block-paragraph"><strong>Get exactly what you need and nothing more with a single query.</strong></p>



<p class="wp-block-paragraph">Does it sound amazing? Absolutely. But if you’ve ever tried to implement GraphQL for an entire engineering team, you’ve probably realized that it’s not quite as simple as it sounds to achieve. For any dev in the organization to be able to get everything they need in a single query, <em>everything</em> that anyone could need has to exist in a single graph.&nbsp;</p>



<p class="wp-block-paragraph">The concept of a single graph for everything seems all but impossible when you think about it from a compliance perspective, and that was one of the biggest challenges we faced when we started to scale up our use of GraphQL at Priceline. As a travel booking platform that supports millions of customers around the world, our backend services contain quite a bit of PCI data that can’t be made accessible to our client apps.&nbsp;</p>



<p class="wp-block-paragraph">One graph → one endpoint → client apps have access to everything, including cardholder information and other sensitive data. Right?</p>



<p class="wp-block-paragraph">Well it turns out, not necessarily. With a <a href="https://www.apollographql.com/blog/announcement/backend/the-supergraph-a-new-way-to-think-about-graphql/">supergraph</a>, we can have a single graph that unifies all of all of our data and services, including sensitive data, but we can selectively choose which parts of the graph are exposed to various audiences, like app devs. In this post I’ll walk you through how we did this for the Priceline supergraph and how you can set it up yourself using contracts in Apollo Studio.</p>



<h2 class="wp-block-heading"><a href="#is-a-supergraph-worth-it" aria-hidden="true" class="aal_anchor" id="is-a-supergraph-worth-it"><svg aria-hidden="true" class="aal_svg" height="16" version="1.1" viewBox="0 0 16 16" width="16"><path fill-rule="evenodd" d="M4 9h1v1H4c-1.5 0-3-1.69-3-3.5S2.55 3 4 3h4c1.45 0 3 1.69 3 3.5 0 1.41-.91 2.72-2 3.25V8.59c.58-.45 1-1.27 1-2.09C10 5.22 8.98 4 8 4H4c-.98 0-2 1.22-2 2.5S3 9 4 9zm9-3h-1v1h1c1 0 2 1.22 2 2.5S13.98 12 13 12H9c-.98 0-2-1.22-2-2.5 0-.83.42-1.64 1-2.09V6.25c-1.09.53-2 1.84-2 3.25C6 11.31 7.55 13 9 13h4c1.45 0 3-1.69 3-3.5S14.5 6 13 6z"></path></svg></a>Is a supergraph worth it?</h2>



<p class="wp-block-paragraph">Let’s take a step back – is it even worth it to put everything into one graph? Couldn’t we just have entirely separate graphs for internal systems that require sensitive data and for client apps that don’t? We could, and at Priceline we actually did at first, but we would end up with a lot of duplicative maintenance work that could be avoided.</p>



<p class="wp-block-paragraph">There’s always going to be overlap between what internal systems need and what client apps need. For example, our booking graph, which was not part of the supergraph, contained airline policy schema used for display when a customer was booking a flight. Our native apps teams wanted to display this information to a customer viewing flight information, earlier in the funnel. However, they did not want the overhead of multiple network requests. Normally this would result in duplicating the airline policy schema inside the supergraph. Not ideal.</p>



<p class="wp-block-paragraph">And that’s just one example. To provide a specific subset of services for a certain audience or experience that differed from an already existing graph, we either had to use preexisting REST APIs or create an entirely new graph to support it. IT systems app? Separate graph. Partner API? Separate graph.&nbsp;</p>



<p class="wp-block-paragraph">With a supergraph, we could create a single source of truth for definitions of every entity in our data model (hotel, flight, rental car, customer, etc), eliminating a huge amount of maintenance work associated with these disparate graphs. For us, it was worth it.</p>

<p class="wp-block-paragraph">As a single source of truth, our supergraph schema contains everything, including sensitive data. So we can’t just have every application query the endpoint for the entire supergraph directly. Instead, we need to define which parts of the supergraph certain applications are allowed to access. We can do this by creating contract graphs in Apollo Studio.</p>



<h3 class="wp-block-heading"><a href="#contract-graphs-filtered-representations-of-the-supergraph" aria-hidden="true" class="aal_anchor" id="contract-graphs-filtered-representations-of-the-supergraph"><svg aria-hidden="true" class="aal_svg" height="16" version="1.1" viewBox="0 0 16 16" width="16"><path fill-rule="evenodd" d="M4 9h1v1H4c-1.5 0-3-1.69-3-3.5S2.55 3 4 3h4c1.45 0 3 1.69 3 3.5 0 1.41-.91 2.72-2 3.25V8.59c.58-.45 1-1.27 1-2.09C10 5.22 8.98 4 8 4H4c-.98 0-2 1.22-2 2.5S3 9 4 9zm9-3h-1v1h1c1 0 2 1.22 2 2.5S13.98 12 13 12H9c-.98 0-2-1.22-2-2.5 0-.83.42-1.64 1-2.09V6.25c-1.09.53-2 1.84-2 3.25C6 11.31 7.55 13 9 13h4c1.45 0 3-1.69 3-3.5S14.5 6 13 6z"></path></svg></a>Contract graphs: filtered representations of the supergraph</h3>



<p class="wp-block-paragraph">Contract graphs are variants of the overall supergraph that only contain a filtered subset of the fields and types defined in the supergraph schema. Deriving a contract graph’s schema from the supergraph schema requires two things:</p>



<ol class="wp-block-list"><li>Using the <code class="" data-line="">@tag</code> directive to apply tags to fields, interfaces, objects, and unions in your subgraph schemas.</li><li>Creating a contract in Apollo Studio that defines which tags should be included or excluded from the contract schema</li></ol>



<p class="wp-block-paragraph">Once you’ve tagged your subgraph schemas and created your contract in Apollo Studio, the contract graph schema will automatically be derived from the supergraph schema whenever it’s composed in Studio. The contract schema can be used to power Apollo Router or Apollo Gateway to create a running contract graph with its own endpoint.</p>

<p class="wp-block-paragraph">At Priceline, we use a contract graph to prevent clients from sending and requesting cardholder data through the supergraph, to the booking subgraph. The fewer touchpoints with this sensitive information, the better. As I mentioned earlier, the booking subgraph also contains airline policy information which we do need client apps to have access to so that we can display it to customers on a variety of pages</p>



<p class="wp-block-paragraph">Using the <code class="" data-line="">@tag</code> directive, we tagged all of the sensitive entities in the Checkout subgraph with <code class="" data-line="">PCI</code>. Then, we defined a contract in Apollo Studio that excludes anything tagged with <code class="" data-line="">PCI</code>. The derived contract graph is what our client apps query rather than the supergraph itself.</p>



<p class="wp-block-paragraph"><strong>That’s it.</strong></p>



<p class="wp-block-paragraph">Applying tags within your subgraph schemas and creating a contract in Studio is all you need to do to create contract graphs that remove access to sensitive data. And, because contract graphs derive their schema from the supergraph, they are automatically kept up-to-date with any changes in the supergraph schema. Modifying the entities included in a contract graph is as easy as editing tags in your subgraph schema or the filters in Apollo Studio.</p>

While <a href="https://www.apollographql.com/docs/apollo-server/">Apollo Server</a> makes building your own API a delight, sometimes you don&#8217;t want to get your hands dirty if you don&#8217;t have to. As luck would have it, some really awesome GraphQL APIs are available that you can use for free!</p>



<p class="wp-block-paragraph">Here&#8217;s 8 of them you can use today along with an example query for each one to get you started:</p>

GraphQL Summit Worldwide is back!


<p class="wp-block-paragraph">At StockX, we&#8217;ve been running a federated GraphQL implementation for over a year now. Like any distributed system, the rewards it comes with also comes with challenges to overcome. Overall, we&#8217;ve had a positive experience serving our APIs with GraphQL and Apollo Federation.</p>



<p class="wp-block-paragraph">In this post, I&#8217;d like to highlight some of the most important lessons we’ve learned over the past year running a federated graph in production.</p>



<h2 class="wp-block-heading" id="build-your-schema-as-you-go-dont-try-to-do-it-all-at-once"><a href="#1-build-your-schema-as-you-go-dont-try-to-do-it-all-at-once" aria-hidden="true" class="aal_anchor" id="1-build-your-schema-as-you-go-dont-try-to-do-it-all-at-once"><svg aria-hidden="true" class="aal_svg" height="16" version="1.1" viewBox="0 0 16 16" width="16"><path fill-rule="evenodd" d="M4 9h1v1H4c-1.5 0-3-1.69-3-3.5S2.55 3 4 3h4c1.45 0 3 1.69 3 3.5 0 1.41-.91 2.72-2 3.25V8.59c.58-.45 1-1.27 1-2.09C10 5.22 8.98 4 8 4H4c-.98 0-2 1.22-2 2.5S3 9 4 9zm9-3h-1v1h1c1 0 2 1.22 2 2.5S13.98 12 13 12H9c-.98 0-2-1.22-2-2.5 0-.83.42-1.64 1-2.09V6.25c-1.09.53-2 1.84-2 3.25C6 11.31 7.55 13 9 13h4c1.45 0 3-1.69 3-3.5S14.5 6 13 6z"></path></svg></a>1. Build your schema as you go, don&#8217;t try to do it all at once.</h2>



<p class="wp-block-paragraph">When we first started using GraphQL, we initially tried to create as much of the schema as possible. That worked great for a proof of concept, but it wasn&#8217;t until we got the green light to build it for production that we realized that <strong>upfront schema design</strong> isn&#8217;t the best idea.&nbsp;</p>



<p class="wp-block-paragraph">Our initial approach was to mirror the shape of the existing RESTful API calls, but this resulted in many extra fields that no one was using. A year later, we are <em>still</em> in the process of removing those unused fields.&nbsp;<br></p>



<p class="wp-block-paragraph">We now believe in something we call <em>Just In Time Schema (JITS) </em>development. It&#8217;s essentially the term <a href="https://martinfowler.com/bliki/Yagni.html">YAGNI</a> (you ain&#8217;t gonna need it) but applied to schema design; this means that it&#8217;s not until a consumer <em>truly</em> needs a particular field or a type that we expose it.</p>



<h2 class="wp-block-heading"><a href="#2-documenting-the-schema-helps-a-lot" aria-hidden="true" class="aal_anchor" id="2-documenting-the-schema-helps-a-lot"><svg aria-hidden="true" class="aal_svg" height="16" version="1.1" viewBox="0 0 16 16" width="16"><path fill-rule="evenodd" d="M4 9h1v1H4c-1.5 0-3-1.69-3-3.5S2.55 3 4 3h4c1.45 0 3 1.69 3 3.5 0 1.41-.91 2.72-2 3.25V8.59c.58-.45 1-1.27 1-2.09C10 5.22 8.98 4 8 4H4c-.98 0-2 1.22-2 2.5S3 9 4 9zm9-3h-1v1h1c1 0 2 1.22 2 2.5S13.98 12 13 12H9c-.98 0-2-1.22-2-2.5 0-.83.42-1.64 1-2.09V6.25c-1.09.53-2 1.84-2 3.25C6 11.31 7.55 13 9 13h4c1.45 0 3-1.69 3-3.5S14.5 6 13 6z"></path></svg></a>2. Documenting the Schema helps. A lot.</h2>



<p class="wp-block-paragraph">One thing that has been a massive help for consumers of our graph is the ability to document the schema and make that documentation easily consumable. Internally, we had an enormous lack of documentation, and our APIs&#8217; usage relied a little too much upon tribal knowledge.&nbsp;<br></p>



<p class="wp-block-paragraph">With <a href="https://www.apollographql.com/docs/apollo-server/schema/schema/#documentation-strings">documentation strings</a>, the schema has become a large part of our documentation for consumers. People no longer have to guess what you can do with our API. It&#8217;s been a breath of fresh air, and we no longer have to have to track down which query params work and which ones don&#8217;t.</p>



<h2 class="wp-block-heading"><a href="#3-the-performance-improvement-is-real" aria-hidden="true" class="aal_anchor" id="3-the-performance-improvement-is-real"><svg aria-hidden="true" class="aal_svg" height="16" version="1.1" viewBox="0 0 16 16" width="16"><path fill-rule="evenodd" d="M4 9h1v1H4c-1.5 0-3-1.69-3-3.5S2.55 3 4 3h4c1.45 0 3 1.69 3 3.5 0 1.41-.91 2.72-2 3.25V8.59c.58-.45 1-1.27 1-2.09C10 5.22 8.98 4 8 4H4c-.98 0-2 1.22-2 2.5S3 9 4 9zm9-3h-1v1h1c1 0 2 1.22 2 2.5S13.98 12 13 12H9c-.98 0-2-1.22-2-2.5 0-.83.42-1.64 1-2.09V6.25c-1.09.53-2 1.84-2 3.25C6 11.31 7.55 13 9 13h4c1.45 0 3-1.69 3-3.5S14.5 6 13 6z"></path></svg></a>3. The performance improvement is real</h2>



<div class="wp-block-image"><figure class="aligncenter size-large"><img decoding="async" src="https://media.giphy.com/media/dyRT9h6bzA4fDZvPgy/giphy.gif" alt=""/></figure></div>



<p class="wp-block-paragraph">At StockX, GraphQL brought massive performance increases. We&#8217;re talking SECONDS of improvement &#8211; yes, you read that right. Seconds!&nbsp;</p>



<p class="wp-block-paragraph">The most critical performance improvement we enjoyed was the reduction of payload size; with GraphQL, payload sizes were up to 7 times smaller! We noticed that every metric we were tracking on mobile devices seemed to improve once we made the payload reduction.</p>



<p class="wp-block-paragraph">Architecturally, GraphQL does become the choke point for requests. This led us to look into improving multiple parts of our edge layer. Before GraphQL, we used various caching strategies since our serverless handlers and servers did their own caching. The shift to GraphQL allowed us to unify our caching approach and increase the overall strategy.&nbsp;</p>



<p class="wp-block-paragraph">With a more unified and easier-to-reason-about caching strategy, we were able to reduce the amount of requests to our backend services.&nbsp;</p>



<p class="wp-block-paragraph"><br><em>Stay tuned for my other post titled &#8220;<strong>Caching Approaches in GraphQL Federation</strong>&#8221; to learn how to cache in a federated GraphQL architecture using memoization, data loader, and distributed caching techniques.</em></p>



<h2 class="wp-block-heading"><a href="#4-theres-a-learning-curve" aria-hidden="true" class="aal_anchor" id="4-theres-a-learning-curve"><svg aria-hidden="true" class="aal_svg" height="16" version="1.1" viewBox="0 0 16 16" width="16"><path fill-rule="evenodd" d="M4 9h1v1H4c-1.5 0-3-1.69-3-3.5S2.55 3 4 3h4c1.45 0 3 1.69 3 3.5 0 1.41-.91 2.72-2 3.25V8.59c.58-.45 1-1.27 1-2.09C10 5.22 8.98 4 8 4H4c-.98 0-2 1.22-2 2.5S3 9 4 9zm9-3h-1v1h1c1 0 2 1.22 2 2.5S13.98 12 13 12H9c-.98 0-2-1.22-2-2.5 0-.83.42-1.64 1-2.09V6.25c-1.09.53-2 1.84-2 3.25C6 11.31 7.55 13 9 13h4c1.45 0 3-1.69 3-3.5S14.5 6 13 6z"></path></svg></a>4. There&#8217;s a learning curve.</h2>



<p class="wp-block-paragraph">Most people know how RESTful APIs work &#8211; it&#8217;s become something of a web standard. To me, the learning curve for GraphQL resembles a hockey stick. Unless you&#8217;ve integrated with GraphQL or used GraphQL before, there will undoubtedly be a learning curve because it&#8217;s a much different API style from REST. Since you&#8217;re no longer calling an API to get everything the server will give you back as a response, clients need to know what they want and request it.&nbsp;</p>



<p class="wp-block-paragraph">Once you wrap your head around GraphQL, you&#8217;ll notice a mindset change from the RESTful world; and it&#8217;s a world where you can move much faster.</p>



<h2 class="wp-block-heading"><a href="#5-faster-development-cycles" aria-hidden="true" class="aal_anchor" id="5-faster-development-cycles"><svg aria-hidden="true" class="aal_svg" height="16" version="1.1" viewBox="0 0 16 16" width="16"><path fill-rule="evenodd" d="M4 9h1v1H4c-1.5 0-3-1.69-3-3.5S2.55 3 4 3h4c1.45 0 3 1.69 3 3.5 0 1.41-.91 2.72-2 3.25V8.59c.58-.45 1-1.27 1-2.09C10 5.22 8.98 4 8 4H4c-.98 0-2 1.22-2 2.5S3 9 4 9zm9-3h-1v1h1c1 0 2 1.22 2 2.5S13.98 12 13 12H9c-.98 0-2-1.22-2-2.5 0-.83.42-1.64 1-2.09V6.25c-1.09.53-2 1.84-2 3.25C6 11.31 7.55 13 9 13h4c1.45 0 3-1.69 3-3.5S14.5 6 13 6z"></path></svg></a>5. Faster development cycles.</h2>



<p class="wp-block-paragraph">After switching over to GraphQL, we&#8217;ve noticed that our tickets complete faster. Instead of &#8220;Team A&#8221; waiting for &#8220;Team B&#8221; to do something, then &#8220;Team C&#8221; to expose the data for &#8220;Team A&#8221;, teams can now more independently due to their ability to traverse through the graph to get the data they need.</p>



<p class="wp-block-paragraph">For example, when &#8220;Team A&#8221; needs to use a part of the federated graph that they don&#8217;t necessarily own, they don&#8217;t have to wait for other teams to help them. This graphical nature of GraphQL solves more problems than we initially thought.</p>



<h2 class="wp-block-heading"><a href="#6-dont-reinvent-the-wheel" aria-hidden="true" class="aal_anchor" id="6-dont-reinvent-the-wheel"><svg aria-hidden="true" class="aal_svg" height="16" version="1.1" viewBox="0 0 16 16" width="16"><path fill-rule="evenodd" d="M4 9h1v1H4c-1.5 0-3-1.69-3-3.5S2.55 3 4 3h4c1.45 0 3 1.69 3 3.5 0 1.41-.91 2.72-2 3.25V8.59c.58-.45 1-1.27 1-2.09C10 5.22 8.98 4 8 4H4c-.98 0-2 1.22-2 2.5S3 9 4 9zm9-3h-1v1h1c1 0 2 1.22 2 2.5S13.98 12 13 12H9c-.98 0-2-1.22-2-2.5 0-.83.42-1.64 1-2.09V6.25c-1.09.53-2 1.84-2 3.25C6 11.31 7.55 13 9 13h4c1.45 0 3-1.69 3-3.5S14.5 6 13 6z"></path></svg></a>6. Don&#8217;t reinvent the wheel.</h2>



<p class="wp-block-paragraph">GraphQL is excellent, but it still faces the same problems as any other technology out in the wild. For example, scaling is a challenge you&#8217;ll want to tackle with well-known architectural best practices.&nbsp;</p>



<p class="wp-block-paragraph">That means using Apollo Federation to implement a microservice-like architecture by decoupling our graph by <em>concern</em>; this enables teams to manage their distinct parts of a single federated GraphQL API, scale traffic more effectively, and ship code faster.</p>



<p class="wp-block-paragraph">We initially tried to build our own &#8220;pure&#8221; GraphQL server/schema. It wasn&#8217;t until we exposed it to production traffic and experienced common challenges serving a monolithic API that we realized we needed to follow trusty distributed computing best practices.</p>



<h2 class="wp-block-heading"><a href="#7-graphql-federation-scales-well-horizontally" aria-hidden="true" class="aal_anchor" id="7-graphql-federation-scales-well-horizontally"><svg aria-hidden="true" class="aal_svg" height="16" version="1.1" viewBox="0 0 16 16" width="16"><path fill-rule="evenodd" d="M4 9h1v1H4c-1.5 0-3-1.69-3-3.5S2.55 3 4 3h4c1.45 0 3 1.69 3 3.5 0 1.41-.91 2.72-2 3.25V8.59c.58-.45 1-1.27 1-2.09C10 5.22 8.98 4 8 4H4c-.98 0-2 1.22-2 2.5S3 9 4 9zm9-3h-1v1h1c1 0 2 1.22 2 2.5S13.98 12 13 12H9c-.98 0-2-1.22-2-2.5 0-.83.42-1.64 1-2.09V6.25c-1.09.53-2 1.84-2 3.25C6 11.31 7.55 13 9 13h4c1.45 0 3-1.69 3-3.5S14.5 6 13 6z"></path></svg></a>7. GraphQL federation scales well horizontally.</h2>



<p class="wp-block-paragraph">After putting our federated GraphQL implementation into production, we found that horizontal scaling was the best way for us to serve large traffic loads.&nbsp;</p>



<p class="wp-block-paragraph">We use NodeJS- and with NodeJS being single-threaded, it allows for more requests to be handled simultaneously.&nbsp;</p>



<p class="wp-block-paragraph">We still have to preemptively scale our systems before large traffic spikes like a push notification or other marketing events. But one of the beautiful parts of using Federation is that we can scale <em>only</em> the implementing services affected by the event.&nbsp;</p>



<p class="wp-block-paragraph">For example, if we send out an email to clients about a fantastic blog post, we can scale the blog portion of our federated architecture and leave everything else the same. This is great when we look at the cost of running our services. Due to not having to scale everything, we save money.</p>

<p class="wp-block-paragraph">We have had some stumbles while adopting GraphQL. The team at StockX has had no prior experience with GraphQL.&nbsp;</p>



<p class="wp-block-paragraph">So we read, and then read, then read even more. The amount of knowledge out there has helped us make more informed decisions. Some of the articles we found helpful were:</p>



<ul class="wp-block-list"><li><a href="https://graphql.org/learn/best-practices/">GraphQL Best Practices from GraphQL.org</a></li><li><a href="https://relay.dev/graphql/connections.htm">GraphQL Cursor Specification from Relay.dev</a></li><li><a href="https://graphql.org/learn/pagination/">How to Handle Pagination from GraphQL.org</a></li></ul>



<h2 class="wp-block-heading"><a href="#9-graphql-forces-domain-conversations" aria-hidden="true" class="aal_anchor" id="9-graphql-forces-domain-conversations"><svg aria-hidden="true" class="aal_svg" height="16" version="1.1" viewBox="0 0 16 16" width="16"><path fill-rule="evenodd" d="M4 9h1v1H4c-1.5 0-3-1.69-3-3.5S2.55 3 4 3h4c1.45 0 3 1.69 3 3.5 0 1.41-.91 2.72-2 3.25V8.59c.58-.45 1-1.27 1-2.09C10 5.22 8.98 4 8 4H4c-.98 0-2 1.22-2 2.5S3 9 4 9zm9-3h-1v1h1c1 0 2 1.22 2 2.5S13.98 12 13 12H9c-.98 0-2-1.22-2-2.5 0-.83.42-1.64 1-2.09V6.25c-1.09.53-2 1.84-2 3.25C6 11.31 7.55 13 9 13h4c1.45 0 3-1.69 3-3.5S14.5 6 13 6z"></path></svg></a>9. GraphQL forces domain conversations.</h2>



<p class="wp-block-paragraph">When we first started GraphQL, our types were a mess. Sure, our endpoints <em>structurally </em>returned the same payload as the RESTful API we had in place before, and that made the front-ends work, but it was a mess to work with.&nbsp;</p>



<p class="wp-block-paragraph">Eventually, we had the opportunity to design the graph from scratch again, starting clean.&nbsp;</p>



<p class="wp-block-paragraph">We used this opportunity to start conversations which led to a better understanding of the division of responsibilities and relationships between services and types. We discussed what fields belong in which type, what to do with our massive existing types, and how to break them into smaller, better namespaced types. We’re now at a point where our dedicated selection of types work much better for us.</p>

<p class="wp-block-paragraph">It was a lot of work to migrate to GraphQL, but looking back at all that work over the last year, I <em>still </em>think that migration was a major success and was incredibly impactful to the way we work today. GraphQL has enabled us to have faster development cycles, push smaller chunks to production with fewer problems, rethink our UX, among so many other improvements.</p>

<p class="wp-block-paragraph">For this project, you will need to have nodejs and mongodb installed on your system.</p>

<p class="wp-block-paragraph">Let&#8217;s start by creating our NodeJS project. Create a new folder named&nbsp;<code class="" data-line="">accounts-js-server</code>, all the project files should be inside this folder. Let&#8217;s initialize our new project using&nbsp;<code class="" data-line="">npm</code>&nbsp;(you can use&nbsp;<code class="" data-line="">yarn</code>&nbsp;if you prefer):</p>



<pre class="wp-block-prismatic-blocks"><code class="" data-line="">npm init</code></pre>



<p class="wp-block-paragraph">Now, let&#8217;s add the dependencies we need to setup our Apollo GraphQL server.</p>



<pre class="wp-block-prismatic-blocks"><code class="" data-line="">npm install apollo-server graphql</code></pre>



<p class="wp-block-paragraph">Create a new&nbsp;<code class="" data-line="">index.js</code>&nbsp;file (to make this tutorial simpler all our code will be in a single file) and add this code to setup the Apollo server.</p>



<pre class="wp-block-prismatic-blocks"><code class="language-javascript" data-line="">// index.js

const { ApolloServer, gql } = require(&#039;apollo-server&#039;);

const typeDefs = gql`
  type Query {
    # This query will be protected so only authenticated users can access it
    sensitiveInformation: String
  }
`;

const resolvers = {
  Query: {
    sensitiveInformation: () =&gt; &#039;Sensitive info&#039;,
  },
};

const server = new ApolloServer({ typeDefs, resolvers });

// The `listen` method launches a web server.
server.listen().then(({ url }) =&gt; {
  console.log(`🚀  Server ready at ${url}`);
});</code></pre>



<p class="wp-block-paragraph">Now let&#8217;s start the server to make sure everything is working as expected.</p>



<pre class="wp-block-prismatic-blocks"><code class="" data-line="">node index.js</code></pre>



<p class="wp-block-paragraph">In your console you should see:</p>



<pre class="wp-block-prismatic-blocks"><code class="" data-line="">🚀  Server ready at http://localhost:4000/</code></pre>



<p class="wp-block-paragraph">Our GraphQL server is now ready, it&#8217;s time to add accounts-js!</p>

<p class="wp-block-paragraph">First, we will setup mongoose and connect to our database.</p>



<pre class="wp-block-prismatic-blocks"><code class="" data-line="">npm install @accounts/mongo mongoose</code></pre>



<pre class="wp-block-prismatic-blocks"><code class="language-javascript" data-line="">// index.js

const mongoose = require(&#039;mongoose&#039;);
const { Mongo } = require(&#039;@accounts/mongo&#039;);

// We connect mongoose to our local mongodb database
mongoose.connect(&#039;mongodb://localhost:27017/accounts-js-server&#039;, {
  useNewUrlParser: true,
  useUnifiedTopology: true,
});

// We tell accounts-js to use the mongo connection
const accountsMongo = new Mongo(mongoose.connection);</code></pre>



<p class="wp-block-paragraph">Then, we add the accounts-js server dependencies.</p>



<pre class="wp-block-prismatic-blocks"><code class="" data-line="">npm install @accounts/server @accounts/password</code></pre>



<ul class="wp-block-list"><li><code class="" data-line="">@accounts/server</code>: The accounts-js core dependency.</li><li><code class="" data-line="">@accounts/password</code>: The accounts-js password service, it expose a set of function to manage and authenticate users using email + password.</li></ul>



<p class="wp-block-paragraph">It&#8217;s time to setup the accounts-js server configuration</p>



<pre class="wp-block-prismatic-blocks"><code class="language-javascript" data-line="">// index.js

const { AccountsServer } = require(&#039;@accounts/server&#039;);
const { AccountsPassword } = require(&#039;@accounts/password&#039;);

const accountsPassword = new AccountsPassword({
  // You can customise the behavior of the password service by providing some options
});

const accountsServer = new AccountsServer(
  {
    // We link the mongo adapter we created in the previous step to the server
    db: accountsMongo,
    // Replace this value with a strong random secret
    tokenSecret: &#039;my-super-random-secret&#039;,
  },
  {
    // We pass a list of services to the server, in this example we just use the password service
    password: accountsPassword,
  }
);</code></pre>



<p class="wp-block-paragraph">Then, we add the accounts-js graphql dependencies.</p>



<pre class="wp-block-prismatic-blocks"><code class="" data-line="">npm install @accounts/graphql-api @graphql-toolkit/schema-merging @graphql-modules/core</code></pre>



<ul class="wp-block-list"><li><code class="" data-line="">@accounts/graphql-api</code>: The transport layer exposing all the queries and mutations accounts-js provide.</li><li><code class="" data-line="">@graphql-toolkit/schema-merging</code>: Expose a set of tools that will help us to merge our schemas.</li><li><code class="" data-line="">@graphql-modules/core</code>: An internal dependency that accounts-js use to manage his graphql schema and resolvers.</li></ul>



<p class="wp-block-paragraph">Let&#8217;s merge the accounts-js GraphQL schema and our schema, so the user can access it</p>



<pre class="wp-block-prismatic-blocks"><code class="language-javascript" data-line="">// index.js

// Add makeExecutableSchema to the imported variables
const { ApolloServer, gql, makeExecutableSchema } = require(&#039;apollo-server&#039;);
const { mergeTypeDefs, mergeResolvers } = require(&#039;@graphql-toolkit/schema-merging&#039;);
const { AccountsModule } = require(&#039;@accounts/graphql-api&#039;);

// We generate the accounts-js GraphQL module
const accountsGraphQL = AccountsModule.forRoot({ accountsServer });

// A new schema is created combining our schema and the accounts-js schema
const schema = makeExecutableSchema({
  typeDefs: mergeTypeDefs([typeDefs, accountsGraphQL.typeDefs]),
  resolvers: mergeResolvers([accountsGraphQL.resolvers, resolvers]),
  schemaDirectives: {
    ...accountsGraphQL.schemaDirectives,
  },
});

// When we instantiate our Apollo server we use the schema and context properties
const server = new ApolloServer({
  schema,
  context: accountsGraphQL.context,
});</code></pre>



<p class="wp-block-paragraph">At the end, our file should look like this:</p>



<pre class="wp-block-prismatic-blocks"><code class="language-javascript" data-line="">// index.js

const { ApolloServer, gql, makeExecutableSchema } = require(&#039;apollo-server&#039;);
const mongoose = require(&#039;mongoose&#039;);

// We connect mongoose to our local mongodb database

const accountsMongo = new Mongo(mongoose.connection);

const typeDefs = gql`
  type Query {
    # This query will be protected so only authenticated users can access it
    sensitiveInformation: String
  }
`;

const resolvers = {
  Query: {
    sensitiveInformation: () =&gt; &#039;Sensitive info&#039;,
  },
};

const accountsPassword = new AccountsPassword({});

const accountsServer = new AccountsServer(
  {
    db: accountsMongo,
    // Replace this value with a strong secret
    tokenSecret: &#039;my-super-random-secret&#039;,

);

// We generate the accounts-js GraphQL module

const server = new ApolloServer({ schema, context: accountsGraphQL.context });

// The `listen` method launches a web server.
server.listen().then(({ url }) =&gt; {
  console.log(`🚀  Server ready at ${url}`);
});</code></pre>



<p class="wp-block-paragraph">If we restart our server and visit http://localhost:4000/, we should see that the accounts-js queries and mutations are merged with our schema. Our authentication server is now ready 🚀.</p>

<p class="wp-block-paragraph">Inside the GraphQL Playground, let&#8217;s execute the following mutation:</p>



<pre class="wp-block-prismatic-blocks"><code class="language-graphql" data-line="">mutation {
  createUser(
    user: { email: &quot;john.doe@john.com&quot;, password: &quot;superSecurePassword&quot; }
  )
}</code></pre>



<p class="wp-block-paragraph">Congrats, our first user has been created 👏!</p>



<p class="wp-block-paragraph">If you take a look at the&nbsp;<code class="" data-line="">users</code>&nbsp;collection inside mongodb you should see that your user was created and looks like this:</p>



<pre class="wp-block-prismatic-blocks"><code class="language-json" data-line="">{
  &quot;_id&quot;: ObjectId(&quot;5e3da6ba13ef1a137bbc8fe4&quot;),
  &quot;services&quot;: {
    &quot;password&quot;: {
      &quot;bcrypt&quot;: &quot;$2a$10$WwhjvbDzQpS2LrdkcgQJwODn.EE95T0b9NmMUNcHKyrDOlXEeybSq&quot;
    }
  },
  &quot;createdAt&quot;: 1581098682713,
  &quot;updatedAt&quot;: 1581098682713,
  &quot;emails&quot;: [
    {
      &quot;address&quot;: &quot;john.doe@john.com&quot;,
      &quot;verified&quot;: false
    }
  ]
}
</code></pre>



<p class="wp-block-paragraph">What we can see is that a&nbsp;<code class="" data-line="">createdAt</code>&nbsp;and&nbsp;<code class="" data-line="">updatedAt</code>&nbsp;fields have been created. We also see that the password has been saved hashed in the database, we use bcrypt as a default but you can change it to argon2 via the options if you prefer.</p>



<p class="wp-block-paragraph">Now let&#8217;s try to login with this user:</p>



<pre class="wp-block-prismatic-blocks"><code class="language-graphql" data-line="">mutation {
  authenticate(
    serviceName: &quot;password&quot;
    params: {
      user: { email: &quot;john.doe@john.com&quot; }
      password: &quot;superSecurePassword&quot;
    }
  ) {
    sessionId
    tokens {
      accessToken
      refreshToken
    }
  }
}</code></pre>



<p class="wp-block-paragraph">You should see in the playground that a new session has been created. The session is represented by:</p>



<ul class="wp-block-list"><li>a sessionId (you can check the session in the database)</li><li>a short lived JWT accessToken used to authenticate the user</li><li>a long lived refreshToken that can be used to get a new accessToken once it&#8217;s expired</li></ul>



<p class="wp-block-paragraph">Save the access token, we will need it to authenticate our requests in the next part.</p>

<p class="wp-block-paragraph">Our first user has been created and we are now able to login via the API. Next step is to protect our&nbsp;<code class="" data-line="">sensitiveInformation</code>&nbsp;query so only the authenticated users can access it.</p>



<p class="wp-block-paragraph">accounts-js provide an&nbsp;<code class="" data-line="">@auth</code>&nbsp;directive that we can use to protect our private queries.</p>



<p class="wp-block-paragraph">Let&#8217;s add the directive to the query in our schema:</p>



<pre class="wp-block-prismatic-blocks"><code class="language-javascript" data-line="">// index.js

const typeDefs = gql`
  type Query {
    # We add the @auth directive
    sensitiveInformation: String @auth
  }
`;</code></pre>



<p class="wp-block-paragraph">If you try this query, you should get an&nbsp;<code class="" data-line="">Unauthorized</code>&nbsp;error 🛑. We can&#8217;t access this resource because we are not authenticated. To authenticate our request with the server we need to add the access token saved previously as a header of the request. The header key should be&nbsp;<code class="" data-line="">authorization</code>&nbsp;and the value should be prefixed with&nbsp;<code class="" data-line="">Bearer</code>. eg:&nbsp;<code class="" data-line="">{ &quot;authorization&quot;: &quot;Bearer my-access-token&quot; }</code></p>

<p class="wp-block-paragraph">You made your first authenticated query, how cool is that?</p>



<p class="wp-block-paragraph">Well, that&#8217;s it, you are done, you now have a Graphql server that can register and authenticate new users. Pretty simple right? Next step for you is to explore the playground and play with the different queries and mutations available (verify the email, change the password etc..) :).</p>

<p class="wp-block-paragraph">When we first started the Apollo blog in 2016, publishing on Medium was a natural choice because it allowed us to reach developers that may have not otherwise heard of us. It worked! Over the years, we amassed an audience of over 26,000 subscribers who enjoy learning about Apollo.</p>



<p class="wp-block-paragraph">While we want our articles to reach as many developers as possible, that goal shouldn’t come at the expense of our readers. In recent months, we’ve been disappointed with Medium’s pop-ups and paywall that distract from the reading experience and restrict developers from accessing our content.</p>



<p class="wp-block-paragraph">Instead, we decided to move off Medium in favor of creating <a href="https://www.apollographql.com/blog/" rel="noreferrer noopener" target="_blank">our own blog</a> with Gatsby, WordPress, and Netlify. Gatsby enables us to use React for our site’s frontend while querying WordPress at build time, resulting in a blog that’s fast, consistent with other Apollo sites like <a href="https://www.apollographql.com/docs/" rel="noreferrer noopener" target="_blank">the docs</a>, and easy to publish.&nbsp;</p>



<p class="wp-block-paragraph">Our blog is <a href="https://github.com/apollographql/blog" rel="noreferrer noopener" target="_blank">open source</a>, so please file an issue if you have any feedback. Additionally, be on the lookout for a deep dive into how we built the Apollo blog from lead Developer Experience engineer <a href="https://medium.com/u/e9878a0ec91c" target="_blank" rel="noreferrer noopener">Trevor Blades</a>!</p>

<p class="wp-block-paragraph">Hear about how the shift from legacy APIs to GraphQL can spark joy and productivity in developers. See Danielle walk through a live demo of connecting backend services to UI with a seamless programming model that extends from server to client using Apollo GraphQL and React.</p>



<p class="wp-block-paragraph"><strong>Who is this webcast for?</strong><br>This is a session for frontend developers of all levels. You’ll see what the modern app developer experience looks like, learn how to get started, and discover what you may not even realize you’re missing.<br><br><strong>Why does this matter?</strong><br><em>With GraphQL, it’s easier than ever to set ourselves up to have a great developer that brings more productivity and satisfaction to our jobs.</em></p>

<p class="wp-block-paragraph">As GraphQL usage increases in an organization, Evans will demonstrate why and how teams should practice agile schema development and iteratively evolve their schema over time.</p>



<p class="wp-block-paragraph">Learn specific practices and workflows that prevent outages, focus work, and foster communication when developing and maintaining a data graph. This includes schema validation, field rollover, and schema documentation.</p>



<p class="wp-block-paragraph"><strong>Who is this webcast for?</strong><br>This webcast is designed for teams with one or more data graph applications in production or development who want to improve their velocity. Developers who plan to modify or maintain a data graph will find the talk particularly interesting.<br><br><strong>Why does this matter?</strong><br>Agile schema development increases data graph developer velocity by preventing outages, focusing backend scope, and providing guided communication between client and server teams. This prevention, focus, and communication save money and time, which leads to more data graph stability, robustness, and features.</p>

<p class="wp-block-paragraph">Learn best practices for your GraphQL schema and client operations. We’ll start with some common do’s and don’ts for your schema that will help client more easily consumer your graph. Then we’ll cover some common pitfalls we see in GraphQL operations and how some small changes can being a lot of clarity to your graph. We’ll also sprinkle in some Apollo tooling and what is available in the platform to help support these common do’s and don’ts.</p>



<p class="wp-block-paragraph"><strong>Who is this Session for?</strong><br>Anyone who is using GraphQL (does not have to be using Apollo).<br><br><strong>Why does this matter?</strong><br>It’s important to design a product centric schema that can be easily consumed by clients. As you design your GraphQL schema, you may be starting with only one client application but the future could have hundreds of clients consuming your graph; this will help make sure you’re prepared.<br><br>Now that you have more than one client consuming your graph, you need to really understand who and how is your graph being consumed. This means making sure the operations are clients are sending us makes sense for our organization.</p>

<p class="wp-block-paragraph">Apollo Federation brought a new architecture to GraphQL and a new way of thinking about how to design and build a schema, but what does it mean for how your team builds a data graph? During this webcast, you will learn about the architectural principles behind federation and see how you can implement a well designed and structured data graph using Apollo.</p>



<p class="wp-block-paragraph"><strong>Who is this Session for?</strong><br>This session is for developers, engineering managers, and architects who want a deeper understanding of Apollo Federation, starting at its core concepts.<br><br><strong>Why does this matter?</strong><br>Apollo Federation is a principled implementation of a “single graph,” enabling different teams to collaborate, contribute, and manage a single graph whose implementation is loosely-coupled. Because Federation is built upon the core GraphQL syntax, it is declarative. Federation brings new opportunities to scale and optimize GraphQL across the enterprise.</p>

Roadmap to your data graph: webcast and Q&A series


<p class="wp-block-paragraph">Managing customer experiences across all the products in a single brand is hard enough. Now imagine doing that for 25 brands and more than 200 websites. Expedia Group has managed to sustain incredible growth over the years, but growing that large that quickly was bound to create a fair amount of technical debt. Development teams found themselves spending more and more time duplicating work across platforms and managing service APIs — and less time innovating on new travel offerings.</p>



<p class="wp-block-paragraph">As it goes with technical debt, every new experience and every new platform made matters exponentially worse. In particular, it was the rise of native mobile clients that really ramped up the complexity.</p>



<p class="wp-block-paragraph"><a href="https://twitter.com/imnotdanbo" target="_blank" rel="noreferrer noopener">Dan Boerner</a>, Distinguished Product Manager at Expedia Group explained:</p>



<blockquote class="wp-block-quote is-layout-flow wp-block-quote-is-layout-flow"><p>“Much of the mobile app team’s work had nothing to do with creating experiences for customers because they were constantly figuring out what API to call, on-boarding those APIs, and dealing with version and endpoint changes.”</p></blockquote>



<p class="wp-block-paragraph">To resolve their technical debt, they made a strategic decision to build a GraphQL-based data graph with Apollo.</p>

In their&nbsp;<a href="https://www.apollographql.com/customers/expediagroup" target="_blank" rel="noreferrer noopener">new customer story</a>, you’ll get a comprehensive look at their unique technical and organizational challenges, early experimentation with Backend-For-Frontend, and where they landed with an agile approach to building out a single organization-wide data graph for GraphQL.</p>



<p class="wp-block-paragraph">The results have been nothing short of transformational, both in accelerating development and in freeing up resources to experiment more.</p>



<p class="wp-block-paragraph">As&nbsp;<a href="https://www.linkedin.com/in/tyler-fleck-09b33125/" target="_blank" rel="noreferrer noopener">Tyler Fleck</a>, Director of User Experience, explains it:</p>



<blockquote class="wp-block-quote is-layout-flow wp-block-quote-is-layout-flow"><p>“Trying out new ideas across all our clients without the need to make any client-specific changes speeds up the design and learning process, and ultimately leads to better customer experiences.”</p></blockquote>



<p class="wp-block-paragraph">There are tons of learnings and practical tips to take away, whether you’re a small team starting out in your GraphQL journey or far along and looking to scale a data graph across teams.</p>

Join our first Apollo Day webcast, live from Seattle on July 16th


<p class="wp-block-paragraph">As developers, we constantly interact with documentation. It’s what welcomes us to a project for the first time, it’s a trusted companion that guides us toward celebrating our first “Hello World,” and it’s the first place we turn when we’re frustrated with a bug or curious about a new feature.</p>



<p class="wp-block-paragraph">Good documentation is at the heart of crafting an excellent developer experience, which is why we’re making a big investment in improving our docs at Apollo. Today, we’re excited to share the first big milestone on our journey:&nbsp;<strong>Apollo’s&nbsp;</strong><a href="https://www.apollographql.com/docs/" target="_blank" rel="noreferrer noopener"><strong>new docs site</strong></a><strong>&nbsp;built with Gatsby!&nbsp;</strong>🚀</p>

<p class="wp-block-paragraph">Previously, our docs site was built with Hexo, a static site generator, and shared its theme with Meteor. Although we love our Meteor roots, the shared theme was becoming difficult for our team to maintain and evolve over time.</p>



<p class="wp-block-paragraph">We wanted to migrate to React so we could share UI across all Apollo sites and add interactive elements to our docs. While I wouldn’t normally advocate for a rewrite, our team decided it was necessary in order to modernize our stack. Both our&nbsp;<a href="https://www.apollographql.com/" target="_blank" rel="noreferrer noopener">homepage</a>&nbsp;and the&nbsp;<a href="https://www.apollographql.com/" target="_blank" rel="noreferrer noopener">GraphQL Summit site</a>&nbsp;are built with&nbsp;<a href="https://www.gatsbyjs.org/" target="_blank" rel="noreferrer noopener">Gatsby</a>, so it was an easy choice for our new docs infrastructure.</p>

<p class="wp-block-paragraph">With nearly 200 repositories in the&nbsp;<a href="https://github.com/apollographql" target="_blank" rel="noreferrer noopener">Apollo organization on GitHub</a>, it’s important that each project’s documentation lives alongside the code. When we first heard about&nbsp;<a href="https://www.gatsbyjs.org/blog/2018-11-11-introducing-gatsby-themes/" target="_blank" rel="noreferrer noopener">Gatsby’s new themes feature</a>, Apollo engineer&nbsp;<a href="https://medium.com/u/e9878a0ec91c?source=post_page-----5645b9d56260----------------------" target="_blank" rel="noreferrer noopener">Trevor Blades</a>&nbsp;quickly built a proof-of-concept that confirmed it would be perfect for our needs.</p>



<p class="wp-block-paragraph">Gatsby themes allow you to easily compose UI, configuration, and functionality across multiple sites. Themes are distributed as npm packages, and we use them for sharing versioning logic, constructing the left-hand navigation, common layout components, and more. Not only are Gatsby themes awesome for building docs sites, they’re also great for quickly spinning up derivative sites like&nbsp;<a href="https://principledgraphql.com/" target="_blank" rel="noreferrer noopener">Principled GraphQL</a>, which was built by extending&nbsp;<code class="" data-line="">&lt;a href=&quot;https://github.com/apollographql/gatsby-theme-apollo/&quot; target=&quot;_blank&quot; rel=&quot;noreferrer noopener&quot;&gt;gatsby-theme-apollo&lt;/a&gt;</code>.</p>



<p class="wp-block-paragraph">We’ve been really happy with themes so far, and can’t wait to explore them further. Thank you to&nbsp;<a href="https://medium.com/u/8cb9e0fea905?source=post_page-----5645b9d56260----------------------" target="_blank" rel="noreferrer noopener">Christopher Biscardi</a>&nbsp;and the rest of the Gatsby team for all their support along the way! 🤗</p>

<p class="wp-block-paragraph">When designing our new UI, we wanted to focus on making our content more discoverable. Previously, our layout displayed too much information on the left sidebar, which made it difficult to find what you were looking for without scrolling. Apollo designer&nbsp;<a href="https://medium.com/u/12880b6da5ba?source=post_page-----5645b9d56260----------------------" target="_blank" rel="noreferrer noopener">Jess Marina</a>&nbsp;rose to the challenge and created a cleaner layout and navigation structure to solve this pain point.</p>

<p class="wp-block-paragraph">For our new docs site, we removed article details from the left sidebar and added a navigation panel to the right of the screen to show users all the topics that would be covered on a page. We also made each section on the left sidebar expand and contract so users could zero in on the pages that are relevant to them.</p>

<p class="wp-block-paragraph">Since our docs site spans a large breadth of content, we wanted to improve the search experience. We moved the search bar to a more prominent location, redesigned the search menu, and added a keyboard command to trigger search.</p>

<p class="wp-block-paragraph">We’re happy with the progress we’ve made toward improving the&nbsp;<a href="https://www.apollographql.com/docs/" target="_blank" rel="noreferrer noopener">Apollo docs</a>&nbsp;experience, but our work isn’t done yet! Over the next few months, we will be working on a refactor of our information architecture in order to help developers find what they’re looking for faster. Before embarking on this project, we will conduct user testing and publicize a plan to the Apollo community for feedback. If you’re interested in contributing, check out our&nbsp;<a href="https://spectrum.chat/apollo/docs" target="_blank" rel="noreferrer noopener">Docs channel on Spectrum</a>&nbsp;to learn more.</p>



<p class="wp-block-paragraph">With our new infrastructure, we’ll also be able to support&nbsp;<a href="https://mdxjs.com/" target="_blank" rel="noreferrer noopener">MDX</a>, which will allow us to render React components alongside markdown in the same file. We’re super excited about the creative possibilities MDX will enable, especially with integrating more interactive elements into our docs. Some ideas we’ve started to explore include: interactive code blocks that compile TypeScript to JavaScript, expansion panels with step-by-step instructions, and embedding GraphiQL for running queries.</p>

GraphQL Summit 2019 Call for Proposals


<p class="wp-block-paragraph">It’s been three weeks since the 2018 edition of GraphQL Summit concluded, and we’re still beaming from all of the excitement and energy of the GraphQL community. With over 850 developers in attendance, 35 talks, and countless hallway conversations, we were so inspired by all the learnings and best practices shared by speakers and attendees alike.</p>



<p class="wp-block-paragraph">If there’s one main takeaway from the conference, it’s that&nbsp;<strong>GraphQL has transformed into a developer mega-trend</strong>. Still not convinced? Watch the beginning of Apollo CEO&nbsp;<a href="https://youtu.be/IjJkAL4RWyQ" target="_blank" rel="noreferrer noopener">Geoff Schmidt’s keynote</a>&nbsp;to witness the explosive growth of GraphQL for yourself.</p>



<p class="wp-block-paragraph">Now that all of the talks are live on the&nbsp;<a href="https://summit.graphql.com/speakers/" target="_blank" rel="noreferrer noopener">GraphQL Summit site</a>, I wanted to highlight a few that I thought captured some of the most important ideas learned for doing GraphQL right:</p>



<ul class="wp-block-list"><li><strong>One cohesive workflow:&nbsp;</strong><a href="https://www.youtube.com/watch?v=JsvElHDuqoA" target="_blank" rel="noreferrer noopener">Adam Neary’s live-coding demo of Airbnb’s GraphQL development workflow</a>&nbsp;is an inside look at how an investment in tools and workflows makes GraphQL a killer technology for one of the most forward-thinking product engineering organizations.</li><li><strong>Design the schema for your product:</strong>&nbsp;GitHub’s Marc-Andre Giroux has&nbsp;<a href="https://medium.com/@__xuorig__" target="_blank" rel="noreferrer noopener">written extensively</a>&nbsp;about GraphQL based on his experience building two of the largest production uses of it at GitHub and Shopify.&nbsp;<a href="https://youtu.be/pJamhW2xPYw" target="_blank" rel="noreferrer noopener">In his Summit talk</a>, he covers many best patterns for GraphQL schemas, including the importance of designing for product behavior and team collaboration.</li><li><strong>Managing your client state with GraphQL:&nbsp;</strong>At last year’s Summit, Peggy Rayzis introduced the idea of&nbsp;<a href="https://www.apollographql.com/docs/react/essentials/local-state.html" target="_blank" rel="noreferrer noopener">using GraphQL to manage local state</a>&nbsp;by extending your GraphQL schema on the clientwith additional types and fields. One year later, local state management is baked into the core Apollo Client.&nbsp;<a href="https://youtu.be/WM7YsPzWuTA" target="_blank" rel="noreferrer noopener">Watch her talk to learn how to use it</a>&nbsp;— once you try it you’ll never go back.</li><li><strong>Testing GraphQL end-to-end:&nbsp;</strong><a href="https://youtu.be/loA3FwbVt90" target="_blank" rel="noreferrer noopener">Jake Dawkins gave a standing-room-only talk</a>&nbsp;packed full of code examples showing the most important patterns for client tests, server tests, and end-to-end tests of the full GraphQL layer.</li><li><strong>Integrating GraphQL and CI:&nbsp;</strong>James Baxley, longtime leader in the GraphQL ecosystem, led the charge to add schema change validation and operation safelisting to Apollo.&nbsp;<a href="https://youtu.be/pmcjl4WCDwY" target="_blank" rel="noreferrer noopener">In his talk he shows how to tie it all into your CI workflow</a>&nbsp;so you can go into production safely and with confidence.</li><li><strong>Taking an agile approach to GraphQL:</strong>&nbsp;Trulia’s&nbsp;<a href="https://youtu.be/eUrtRzqN0h0" target="_blank" rel="noreferrer noopener">Natalie Qabazard &amp; Aditi Garg walk through the most important lessons they learned</a>&nbsp;adopting GraphQL into Trulia’s product engineering stack. Their best practices are especially relevant for teams newer to GraphQL or engineers coming onto a project.</li><li><strong>Modeling your data with best patterns:</strong>&nbsp;Kiyan Azarbar from Shopify laid out&nbsp;<a href="https://youtu.be/mqaz6vmAGis" target="_blank" rel="noreferrer noopener">14 of the most important patterns</a>&nbsp;their API team has used to build their API, all worth considering early in the design process.</li></ul>



<p class="wp-block-paragraph">If you’re looking for examples of companies adopting GraphQL, we’ve got that too:&nbsp;<a href="https://youtu.be/UBCKJZe6-kA" target="_blank" rel="noreferrer noopener">Audi</a>,&nbsp;<a href="https://youtu.be/NKMDBH0CWHs" target="_blank" rel="noreferrer noopener">Braintree</a>,&nbsp;<a href="https://youtu.be/e6ziHGPkaKM" target="_blank" rel="noreferrer noopener">Netflix</a>,&nbsp;<a href="https://youtu.be/HL7gZnrEy68" target="_blank" rel="noreferrer noopener">PayPal</a>,&nbsp;<a href="https://youtu.be/dstMUwyF5oU" target="_blank" rel="noreferrer noopener">SurveyMonkey</a>,&nbsp;<a href="https://youtu.be/K6_GVXsT8Zs" target="_blank" rel="noreferrer noopener">TV 2 Denmark</a>&nbsp;and others all walked us through their GraphQL journeys.</p>



<p class="wp-block-paragraph">We’re so excited to see what the future holds for GraphQL and can’t wait to see you at next year’s GraphQL Summit! 🚀 Let us know which talks you enjoyed in the comments.</p>

<p class="wp-block-paragraph">On Monday morning news broke of a security vulnerability that impacted the JavaScript ecosystem at large. A popular dependency called&nbsp;<code class="" data-line="">event-stream</code>&nbsp;was discovered to have been compromised. The package, when installed alongside a bitcoin wallet tool called&nbsp;<code class="" data-line="">copay</code>&nbsp;or&nbsp;<code class="" data-line="">copay-dash</code>, would attempt to siphon and steal bitcoins from users.</p>



<p class="wp-block-paragraph">We determined that the&nbsp;<code class="" data-line="">vscode</code>&nbsp;package that we use to build the Apollo VS Code editor extension was installing&nbsp;<code class="" data-line="">event-stream</code>. We locked our versions down to a&nbsp;<a href="https://github.com/apollographql/apollo-tooling/pull/739" target="_blank" rel="noreferrer noopener">previous safe version</a>&nbsp;and uploaded a release to the VS Code Marketplace.</p>

<p class="wp-block-paragraph">We received reports of the editor extension being removed from the marketplace and flagged as malicious. Our team reached out to the VS Code team to ask what was happening and why were flagged.</p>

Security notice for Apollo VS Code 11/28/18


<p class="wp-block-paragraph"><em>We’re proud to introduce Claire Hough as our new VP of Engineering. Claire joins Apollo with over 20 years of experience building impactful and inclusive engineering teams at Udemy and Napster. She will be responsible for leading our engineering efforts and ensuring that Apollo continues to help developers build great apps. Please read this post from Claire outlining her vision for Apollo Engineering and help me welcome her to the Apollo community!</em></p>



<p class="wp-block-paragraph"><em>— Matt DeBergalis, Founder &amp; VP of R&amp;D</em></p>



<hr class="wp-block-separator"/>



<p class="wp-block-paragraph">Today, I join the Apollo team with humility, excitement, and resolve.</p>



<p class="wp-block-paragraph">When Chris Shaw, Apollo’s Head of People Operations, reached out to me several weeks ago on a Sunday morning, I wasn’t expecting the conversation to be much more than an executive recruiter call. He and I had a much deeper discussion for over an hour that centered on Apollo’s culture of kindness and transparency. It ended with me receiving an invite to their team event, where I was able to experience the company’s culture for the first time. I immediately felt included by the team, and it was apparent everyone at Apollo loved their work and the company of their teammates.</p>



<p class="wp-block-paragraph">As I continued my conversations with Geoff and Matt and the engineering leadership team, I was struck in awe by what the team and the community behind Apollo had accomplished to date and what they are striving to achieve. I was humbled when I was offered the position to lead engineering at Apollo.</p>



<p class="wp-block-paragraph">The developer tools space is new to me, but I bring enthusiasm and a love of learning to Apollo. One of the most important lessons I learned over the years leading teams at Netscape, Napster, Nextag, and Udemy is to adopt a growth mindset and always be ready to learn new things. Without this approach, I don’t think I would have had the career I’ve had. I still consider myself to be a “work-in-progress” continually trying to figure out how best to serve my teams.</p>



<p class="wp-block-paragraph">As an engineering leader, I strive to create a great work environment where everyone can do their best work while contributing to the organization’s mission and vision. Living up to this statement can be overwhelming, perhaps even unattainable at times. But, I look at this as part of the learning journey.</p>



<blockquote class="wp-block-quote is-layout-flow wp-block-quote-is-layout-flow"><p>I believe creating a great work environment starts with a psychologically safe work environment.</p></blockquote>



<p class="wp-block-paragraph">Creating such an atmosphere is not easy. It takes each person on the team investing in building personal relationships and committing to a journey of broadening awareness while always acting with the best intentions. When everyone feels their unique set of identities, experiences, ideas, and talents are embraced and valued by the team, they are more likely to speak up, engage with teammates, and take risks to achieve greater things.</p>



<p class="wp-block-paragraph">Psychological safety is also essential in building and serving more diverse and inclusive communities around us. Having meaningful conversations, expanding our understanding of all groups especially those from underserved communities, and practicing allyship whenever possible are small actions we can take to promote diversity and inclusion in our community.</p>



<p class="wp-block-paragraph">In addition to a psychologically safe work environment, engineers do their best work when they have the full context of the problems they are trying to solve. I consider Product, Design, and Engineering to be one team working toward creating the best possible products and services for their users. One of the attractions of joining Apollo is that we have access to direct feedback from our customers and the GraphQL community, who are also a part of our extended team.</p>



<p class="wp-block-paragraph">Developers’ ability to do their best work also is directly linked to the quality of the code base, development processes, and development tools. I believe in thoughtful, purposeful, and prompt actions when it comes to development.</p>



<p class="wp-block-paragraph">Consequently, if the code base is outdated and unmanageable, it should be rewritten or refactored back to health. If parts of the development process add no value, we get rid of them. If more consistency and predictability in the process are needed, build them in. If a set of tools allows us to produce higher quality work faster, they should be adopted. I am not trying to make all these actions sound easy; rather, I’m pointing out that these are things we can control. Continuing to evaluate the code base, architecture, development processes, and tools and making prudent investments in these areas are crucial to the success of a fast-growing organization.</p>



<p class="wp-block-paragraph">As software engineers in the industry where our skills are in demand, we all have choices on how we invest our time and energy. We all want to feel good about what we do, and it starts with choosing a right company whose mission speaks to us personally. When you care about the company’s mission, you are motivated to go the extra mile and feel enriched every day.</p>



<p class="wp-block-paragraph">Early in my conversations with Geoff, CEO of Apollo, he spoke passionately about positively enabling developers to build great apps by lowering the barrier for them to succeed. This mission resonated deeply with me. As a person who cares a lot about developer happiness, working with the Apollo team and the community is a compelling and exciting opportunity.</p>



<p class="wp-block-paragraph">When I left Udemy in July 2018, I had hoped my next endeavor would include the following attributes:</p>



<ol class="wp-block-list"><li>A mission-driven company serving others</li><li>A team embracing diversity, inclusion and belonging</li><li>A place where I can continue to learn and grow while contributing to the growth of the team</li></ol>



<p class="wp-block-paragraph">I found all of them at Apollo. Even though I have much to learn to get up to speed, I come on board eager, committed, and dedicated to helping software developers build awesome applications using GraphQL.</p>



<hr class="wp-block-separator"/>



<p class="wp-block-paragraph"><em>I hope you’ll also&nbsp;</em><a href="https://summit.graphql.com/" target="_blank" rel="noreferrer noopener"><em>join us at the 3rd annual GraphQL Summit on Nov 7–8 in San Francisco</em></a><em>.

Why I joined Apollo


<p class="wp-block-paragraph">I’ve never been surfing. To me, surfing forces you to put a lot of trust in the ocean, and I do not trust the ocean at all. If I ever felt the need to go surfing, I probably wouldn’t head out to Mavericks on Day One. Instead, I’d start in a lesson, doing that thing where you lie on your surfboard on the beach and pretend to surf until the instructor trusts you not to drown.</p>



<p class="wp-block-paragraph">With our company&nbsp;<a href="https://www.moonhighway.com/" target="_blank" rel="noreferrer noopener">Moon Highway</a>,&nbsp;<a href="https://www.twitter.com/moontahoe" target="_blank" rel="noreferrer noopener">Alex Banks</a>&nbsp;and I have spent countless hours researching, working with, and writing about GraphQL to ensure that our students and readers do not drown. We know that GraphQL is the future of APIs, but we also know that people don’t adopt new technologies if their first introduction is confusing, complicated, and not fun. If people have a great experience learning, they’ll get excited about working with GraphQL.</p>



<p class="wp-block-paragraph">Getting people excited to build awesome products with GraphQL is our main goal, and now we have a book for that!</p>

<p class="wp-block-paragraph">As much as we try to eliminate confusing jargon in our documentation, you’ll probably encounter some unfamiliar GraphQL terms when you start building apps with Apollo. We understand that a head-first guide into the nitty-gritty of GraphQL vocabulary goes a long way to simplify the GraphQL learning process.</p>



<p class="wp-block-paragraph">Recently, I recommended some resources to a developer trying to get the hang of GraphQL and she requested for them in this order:</p>



<ol class="wp-block-list"><li>GraphQL concepts</li><li>GraphQL on the backend</li><li>GraphQL on the frontend</li></ol>



<p class="wp-block-paragraph">In my response to her, I also provided additional resources on&nbsp;<a href="https://www.apollographql.com/docs/guides/performance.html" target="_blank" rel="noreferrer noopener">performance monitoring</a>&nbsp;and guides on&nbsp;<a href="https://www.apollographql.com/docs/guides/" target="_blank" rel="noreferrer noopener">how to succeed with GraphQL and the Apollo platform</a>. Immediately, I wished there was a simple, straight-forward guide of GraphQL words and terms that I could show her instead.</p>



<p class="wp-block-paragraph">No more wishes! It’s here now. We have defined some of the most common GraphQL vocabulary here in&nbsp;<a href="https://www.apollographql.com/docs/resources/graphql-glossary.html" target="_blank" rel="noreferrer noopener">this handy cheat sheet</a>. We hope that this practical and accessible reference will help you on your journey in learning and comprehending GraphQL.</p>

<p class="wp-block-paragraph">We also came up with a list of frequently asked questions pertinent to different stages in the adoption of GraphQL. As an individual developer, or a team of product developers, moving from experimenting with GraphQL to adoption in your product architecture with open-source platforms like Apollo, several questions pop up such as:</p>



<ol class="wp-block-list"><li>How do I set up caching and authentication?</li><li>When should we start tracking the performance of our queries?</li><li>What’s the best way to design a schema?</li><li>What kind of caching strategy is best for our app?</li></ol>

New! GraphQL Glossary & FAQ guide


<p class="wp-block-paragraph">Thanks to our investments in <a rel="noreferrer noopener" href="https://github.com/apollographql/" target="_blank">Apollo tools and libraries</a>, we’ve had the fortune to work with many product engineering teams putting GraphQL into production. As they move from a few first experiments to serious rollout, they’ve started to ask important questions. What’s the best, right way to use GraphQL and <a rel="noreferrer noopener" href="https://www.apollographql.com/docs/" target="_blank">Apollo</a>? How does it fit with the rest of my infrastructure? Who owns this new data layer, and how do we integrate it into our development workflow?</p>

</div></figure>



<p class="wp-block-paragraph">With those questions in mind, we recently held our first event specifically designed for teams running Apollo in production or well on their way there. We wanted to help teams learn about the best patterns and practices that the ecosystem has converged on, show off some of the tools and we’re building that support these patterns, and — most importantly — connect over 150 attendees with engineers at companies like Airbnb and Brigade that have made big and successful commitments to Apollo and GraphQL. Our goal was to give everyone who came the confidence to commit to GraphQL and go faster and further with it.</p>

<p class="wp-block-paragraph">One big theme of the day was how the ecosystem is converging on a set of tools and patterns. My opening keynote covered some of those and showed off some of what we’re working on, like schema validation with a GitHub integration and <a rel="noreferrer noopener" href="https://www.apollographql.com/docs/apollo-server/v2/" target="_blank">our new Apollo Server 2.0 release</a> with integrated APIs for GraphQL metrics collection, CDN integration, and partial query caching.</p>

Apollo Day SF: from promise to production with GraphQL


<p class="wp-block-paragraph">If you’ve been following Apollo’s progress on this blog, you’ve seen a steady stream of major new features announced across the Apollo project spectrum. While new feature announcements are exciting, behind the scenes contributors and maintainers are constantly working on incremental improvements, to make your tools better.</p>



<p class="wp-block-paragraph">As a quick example, we&#8217;ve recently released&nbsp;<a href="http://github.com/apollographql/apollo-client" target="_blank" rel="noreferrer noopener">Apollo Client 2.3.2</a>. This version includes numerous tweaks and bug fixes, submitted by Apollo&#8217;s amazing community of contributors:</p>

<p class="wp-block-paragraph">We here at Apollo HQ absolutely love the amazing community of users and contributors who have rallied around Apollo! Every day we’re blown away by the community’s level of knowledge, thoughtfulness, dedication and amazing willingness to help out those who are just getting started in the Apollo GraphQL space. We’ve been working really hard on exciting additions to the GraphQL landscape, but while keeping our heads down getting things done, we’ve seen the list of reported issues and PRs continue to grow.</p>



<p class="wp-block-paragraph">Dealing with issues and PRs is definitely one of the most challenging aspects of an open source project. Letting issues and PRs sit without any feedback is something that we want to try to avoid as much as possible. We couldn’t be happier to get community PR’s, and really want to make sure people know their contributions are welcome and appreciated.</p>

<ul class="wp-block-list"><li><strong>Updating all Apollo repos to include new (and accurate) issue/PR workflow and triage guidelines.</strong>&nbsp;This will help make it easier for community members to understand how issues/PRs are going to be reviewed and worked on in the future.</li><li><strong>Dedicating resources to work on reviewing repo issues and PRs.</strong>&nbsp;We’re working on a process to make sure issues are triaged appropriately, and outstanding PRs receive some form of feedback. PRs that are close to being merged will be finished and merged, PRs that are no longer relevant will be closed (<em>sorry!</em>), and PRs that still need a fair amount of work done will be marked as works in progress (and contributors will be notified of what’s missing).</li><li><strong>Outlining a regular release schedule and making sure it’s clearly visible in the project README.</strong>&nbsp;This will let community members know when they can expect to see merged PRs show up in a release. This won’t be added to every repo; just the more popular ones that see regular updates.</li><li><strong>Create new contributor ramp-up guides for the most popular Apollo projects, to make it easy for future contributors to hit the ground running when it comes to submitting PRs.</strong>&nbsp;These guides will outline how a project’s source is designed/structured, where the major chunks of functionality lie, how to build the project, how to add and run tests, how to integrate the project into a sample application while developing, where the changelogs are and how they should be updated, etc.</li><li><strong>Streamlining our changelog process.</strong>&nbsp;Right now the changelogs for various Apollo projects are a bit spread out, making it difficult to ramp-up quickly on what has changed in a certain release. The source for the Apollo Client project, for example, is structured such that a main&nbsp;<code class="" data-line="">apollo-client</code>&nbsp;package is defined, that depends on other packages in the same project (e.g.&nbsp;<code class="" data-line="">apollo-cache</code>,&nbsp;<code class="" data-line="">apollo-cache-inmemory</code>,&nbsp;<code class="" data-line="">apollo-utilities</code>, etc.). These packages are all managed using&nbsp;<a href="https://lernajs.io/" target="_blank" rel="noreferrer noopener">lerna</a>, and are published to NPM as their own standalone packages. Each of these packages currently has their own changelog. When a bug fix is applied to the Apollo Client project, it’s possible that bug fix was actually made in say the&nbsp;<code class="" data-line="">apollo-cache-inmemory&nbsp;</code>package, which means its specific changelog is updated with the fix details. Someone looking for an overview of recent&nbsp;<code class="" data-line="">apollo-client&nbsp;</code>changes will not see this fix in the main&nbsp;<code class="" data-line="">apollo-client</code>&nbsp;changelog. Needless to say, we’re definitely aware that this can cause problems for people, and will be consolidating changelogs.</li><li><strong>Getting the community more involved!</strong>&nbsp;🎉 I think we all know that the Apollo community is absolutely amazing! We’ve received so many excellent library feature requests, bug reports (sometimes with multi-hour created reproductions), PRs for super complex and difficult to work on edge case bugs, amazing documentation sections, the list goes on. Moving forward, we’re going to be much more involved with getting interested community members involved with Apollo projects. Anyone who has shown an interest in a specific Apollo project, has submitted a few accepted PR’s, and is interested in helping triage issues and/or PRs, will be welcomed with open arms. We’ll get you elevated repo privileges and add you to an internal triager Slack channel, where we can all help steer the future direction of Apollo.</li></ul>

<p class="wp-block-paragraph">The good news is that we’ve already started on some of the above changes, tackling the Apollo Client project first. Apollo Client is our most popular library, and has been in need of some tender loving care. Over the past couple of weeks we’ve been working on clearing out the backlog of open issues, and have just about covered every outstanding PR. We’ve moved to a once a week release cycle for&nbsp;<code class="" data-line="">&lt;a href=&quot;https://github.com/apollographql/apollo-client&quot; target=&quot;_blank&quot; rel=&quot;noreferrer noopener&quot;&gt;apollo-client&lt;/a&gt;&nbsp;</code>and have been happily working with community members to get code changes in place. Once we’re satisfied with Apollo Client’s overall repo health (and have a process in place to make sure we don’t fall behind on issues/PRs again), we’ll be tackling&nbsp;<code class="" data-line="">&lt;a href=&quot;https://github.com/apollographql/react-apollo&quot; target=&quot;_blank&quot; rel=&quot;noreferrer noopener&quot;&gt;react-apollo&lt;/a&gt;</code>&nbsp;next.</p>

Evolving Apollo repository maintenance

Apollo is hiring!


<blockquote class="wp-block-quote is-layout-flow wp-block-quote-is-layout-flow"><p>This is a guest post by Mikhail Novikov, who worked on GraphQL schema delegation and schema stitching in the&nbsp;<a href="https://github.com/apollographql/graphql-tools" target="_blank" rel="noreferrer noopener">graphql-tools library</a>.

<p class="wp-block-paragraph">In this article I’m going to talk about schema delegation — a way to automatically forward a GraphQL query (or a part of it) to another schema.&nbsp;Schema delegation allows reusing parts of other schemas without manually querying them.&nbsp;Examples where schema delegation would be particularly appropriate include:</p>



<ul class="wp-block-list"><li>Building a GraphQL gateway that would forward queries to underlying GraphQL microservices</li><li>Using a third-party GraphQL API as part of your schema</li><li>Using a GraphQL database proxy like&nbsp;<a href="https://www.prisma.io/" target="_blank" rel="noreferrer noopener">Prisma</a></li></ul>

<p class="wp-block-paragraph">Let’s consider a GraphQL service for a basic blog API. The schema has two types —&nbsp;<code class="" data-line="">User</code>&nbsp;and&nbsp;<code class="" data-line="">Blog</code>. It also has root fields to retrieve them by their&nbsp;<code class="" data-line="">_id</code>. On top of the service there is a GraphQL gateway implementing a&nbsp;<code class="" data-line="">Node</code>&nbsp;interface for the types of an underlying GraphQL service.</p>



<blockquote class="wp-block-quote is-layout-flow wp-block-quote-is-layout-flow"><p><code class="" data-line="">Node</code>&nbsp;is a common interface in the GraphQL world which indicates any object that can be globally addressed by some&nbsp;<code class="" data-line="">id</code>. It’s usually coupled with a root field called&nbsp;<code class="" data-line="">node</code>, which returns any object of a type that implements&nbsp;<code class="" data-line="">Node</code>, by id. You can read more about&nbsp;<code class="" data-line="">Node</code>&nbsp;interface in&nbsp;<a href="https://facebook.github.io/relay/graphql/objectidentification.htm" target="_blank" rel="noreferrer noopener">this article</a>.</p></blockquote>



<p class="wp-block-paragraph">The gateway reuses the same <code class="" data-line="">User</code> and <code class="" data-line="">Blog</code> types extending them so that they implement the <code class="" data-line="">Node</code> interface. It also provides <code class="" data-line="">node</code> root field on top of the two existing ones. Here are the schemas for the service and the gateway.</p>



<pre class="wp-block-prismatic-blocks"><code class="language-graphql" data-line="">type User {
  _id: ID!
  username: String
  blogs: [Blog]
}

type Blog {
  _id: ID!
  user: User
  title: String!
  text: String
}

type Query {
  userById(id: ID!): User
  blogById(id: ID!): Blog
}</code></pre>



<pre class="wp-block-prismatic-blocks"><code class="language-graphql" data-line="">interface Node {
  id: ID!
}

extend type User implements Node {
  id: ID!
}

extend type Blog implements Node {
  id: ID!
}

extend type Query {
  node(id: ID!): Node
}</code></pre>



<p class="wp-block-paragraph">Instead of reimplementing&nbsp;<code class="" data-line="">userById</code>&nbsp;and&nbsp;<code class="" data-line="">blogById</code>&nbsp;in the gateway, it will execute the query using the service schema. To do it, you could build the query from the information you get as the fourth argument of a resolver —&nbsp;<code class="" data-line="">GraphQLResolveInfo</code>. It has the subquery starting at the current resolver (<code class="" data-line="">fieldNodes</code>), fragments used in the operation (<code class="" data-line="">fragments</code>) and variables in&nbsp;<code class="" data-line="">operation</code>. Out of this information you could create a GraphQL&nbsp;<code class="" data-line="">Document</code>,&nbsp;<code class="" data-line="">print</code>&nbsp;it and send it to the service schema.</p>



<p class="wp-block-paragraph">For the root fields that match with the service fields you don’t need to do anything else. As for the new fields like&nbsp;<code class="" data-line="">node</code>&nbsp;you also need to change the name of the root field depending on the global&nbsp;<code class="" data-line="">id</code>.</p>



<h3 class="wp-block-heading" id="06f1"><a href="#filtering-the-query" aria-hidden="true" class="aal_anchor" id="filtering-the-query"><svg aria-hidden="true" class="aal_svg" height="16" version="1.1" viewBox="0 0 16 16" width="16"><path fill-rule="evenodd" d="M4 9h1v1H4c-1.5 0-3-1.69-3-3.5S2.55 3 4 3h4c1.45 0 3 1.69 3 3.5 0 1.41-.91 2.72-2 3.25V8.59c.58-.45 1-1.27 1-2.09C10 5.22 8.98 4 8 4H4c-.98 0-2 1.22-2 2.5S3 9 4 9zm9-3h-1v1h1c1 0 2 1.22 2 2.5S13.98 12 13 12H9c-.98 0-2-1.22-2-2.5 0-.83.42-1.64 1-2.09V6.25c-1.09.53-2 1.84-2 3.25C6 11.31 7.55 13 9 13h4c1.45 0 3-1.69 3-3.5S14.5 6 13 6z"></path></svg></a>Filtering the query</h3>



<p class="wp-block-paragraph">The above would work for the simpler cases where the query only selects data available on both the gateway and the service. However, it’s not always the case. The underlying service schema doesn’t have <code class="" data-line="">id</code> fields that <code class="" data-line="">Node</code> interface has. In addition, one can only spread the fragment with compatible types: when both <code class="" data-line="">User</code> and <code class="" data-line="">Blog</code> fragments are spread inside the query, it will fail.</p>



<pre class="wp-block-prismatic-blocks"><code class="language-graphql" data-line=""># Source query

{
  node(id: &quot;test-global-id&quot;) {
    id # Does not exist on User or Blog in original schemas
    ... on User { # Only valid in userById 
      username
    }
    ... on Blog { # Only valid in blogById
      title
    }    
  }
}</code></pre>



<p class="wp-block-paragraph">To fix this, the delegation must filter out the incompatible fields and fragments, as well as unused fragments and variables after filter. Of course, you can do it by going through the document manually, tracking down the types and removing all the fields that don’t exist on the original schema. But you don’t have to because there is a&nbsp;<code class="" data-line="">delegateToSchema</code>&nbsp;function inside&nbsp;<code class="" data-line="">graphql-tools</code>&nbsp;that can do all that work for you.</p>



<p class="wp-block-paragraph"><em>Schema delegation is adapting the source query so that it matches the subschema automatically.</em></p>

<p class="wp-block-paragraph"><code class="" data-line="">delegateToSchema</code>&nbsp;creates a GraphQL query that’s a valid query for an underlying schema and executes it. It accepts an object of options:</p>



<ul class="wp-block-list"><li><code class="" data-line="">schema</code>&nbsp;is the sub-schema that should handle the delegated query</li><li><code class="" data-line="">operation</code>&nbsp;is either&nbsp;<code class="" data-line="">&quot;query&quot;</code>,&nbsp;<code class="" data-line="">&quot;mutation&quot;</code>&nbsp;or&nbsp;<code class="" data-line="">&quot;subscription&quot;</code>&nbsp;and determines the operation of the GraphQL document</li><li><code class="" data-line="">fieldName</code>&nbsp;is the root field in the schema from which the query will start</li><li><code class="" data-line="">args</code>&nbsp;is an object of&nbsp;<em>additional</em>&nbsp;arguments to pass to the field.

<p class="wp-block-paragraph">Gateway resolvers using <code class="" data-line="">delegateToSchema</code> will look like:</p>



<pre class="wp-block-prismatic-blocks"><code class="language-javascript" data-line="">import { delegateToSchema } from &#039;graphql-tools&#039;;

const resolvers = {

<p class="wp-block-paragraph">Here is how a <code class="" data-line="">node</code> query would delegate to the service:</p>

<p class="wp-block-paragraph">Schema delegation is often used together with schema stitching. Schema stitching is a process of combining multiple GraphQL schemas together. It simplifies the creation of a gateway schema — especially when there are multiple services. Schema stitching automatically sets up delegation for root fields that already exist in the stitched-together schemas. New root fields (as well as any new non-root fields) require new resolvers. The above gateway schema can be created as follows:</p>



<pre class="wp-block-prismatic-blocks"><code class="" data-line="">import { mergeSchemas, delegateToSchema } from &#039;graphql-tools&#039;;

const extensionSchema = `
  interface Node {
    id: ID!
  }
  extend type User implements Node {
    id: ID!
  }
  extend type Blog implements Node {
    id: ID!
  }
  extend type Query {
    node(id: ID!): Node
  }
`;

const schema = mergeSchemas({
  schemas: [serviceSchema, extensionSchema],
  resolvers: {
    Query: {
      node(parent, { id }, context, info) {
        const { type, localId } = deserializeGlobalId(id);
        let fieldName;
        if (type === &#039;Blog&#039;) {
          fieldName = &#039;blogById&#039;,
        } else if (type === &#039;User&#039;) {
          fieldName = &#039;userById&#039;,
        } else {
          throw new Error(&#039;Invalid global id&#039;);
        }
        return delegateToSchema({
          schema: serviceSchema,
          operation: &#039;query&#039;,
          fieldName,
          args: { id: localId },
          context,
          info,       
         });
      },
    },
    // ... more resolvers
 },
});</code></pre>

GraphQL schema delegation

GraphQL over REST with Node, Heroku, and Apollo Engine


<p class="wp-block-paragraph">Developing new products is difficult, especially by the dependencies involved when talking about frontend UI and server-side APIs. To be truly useful, a UI must display and manipulate real data (likely through APIs). This means that many times, UI is blocked on building a backend. Similarly, building REST APIs through a tool that generates endpoints for you can result in locking API endpoints to a specific database schema (thus breaking proper separation of concerns between the frontend and database schema).</p>



<p class="wp-block-paragraph">Recently, I was able to talk about how the GraphQL SDL addresses these concerns at the <a rel="noreferrer noopener" href="https://www.youtube.com/watch?v=iW4il6wUlvs&amp;list=PLpi1lPB6opQxp6zPDuwhHd8MLm_BhBgN9" target="_blank">Apollo GraphQL meetup</a> in San Francisco.</p>

It is, I would argue, the primary place to define and structure the relationship between the backend and the frontend. Backends can use a schema definition file to abstract the makeup of backend services and frontends can use the SDL and introspection result to validate and pre-ordain queries that will be sent to the server before any resolvers are implemented.</p>

<p class="wp-block-paragraph">First, let’s talk a bit about what the SDL actually is and how to write it. The SDL is a typed language for specifying various objects that can be accessed through a GraphQL API.</p>



<figure class="wp-block-image size-large"><img loading="lazy" decoding="async" width="1024" height="657" src="https://apollographql.wpengine.com/wp-content/uploads/2020/03/1_8l14KSD4oGIE70gxVQxFyw-1024x657.png" alt="" class="wp-image-842" srcset="https://wp.apollographql.com/wp-content/uploads/2020/03/1_8l14KSD4oGIE70gxVQxFyw-1024x657.png 1024w, https://wp.apollographql.com/wp-content/uploads/2020/03/1_8l14KSD4oGIE70gxVQxFyw-300x192.png 300w, https://wp.apollographql.com/wp-content/uploads/2020/03/1_8l14KSD4oGIE70gxVQxFyw-768x492.png 768w, https://wp.apollographql.com/wp-content/uploads/2020/03/1_8l14KSD4oGIE70gxVQxFyw-1200x769.png 1200w, https://wp.apollographql.com/wp-content/uploads/2020/03/1_8l14KSD4oGIE70gxVQxFyw.png 1488w" sizes="auto, (max-width: 1024px) 100vw, 1024px" /><figcaption>Example of the Schema Definition Language</figcaption></figure>



<p class="wp-block-paragraph">This example has two main types,&nbsp;<code class="" data-line="">Post</code>&nbsp;and&nbsp;<code class="" data-line="">Blog</code>. These types are made up of a number of fields that are either required (noted by an exclamation point) or optional. The structure is very similar to a JSON object with normal keys and weird looking values. In this case the values are the types of each field.&nbsp;<code class="" data-line="">Post</code>&nbsp;<code class="" data-line="">id</code>s are required&nbsp;<code class="" data-line="">Strings</code>,&nbsp;<code class="" data-line="">likes</code>&nbsp;are required&nbsp;<code class="" data-line="">Ints</code>, and the&nbsp;<code class="" data-line="">blog</code>&nbsp;field refers to&nbsp;<code class="" data-line="">Blog</code>&nbsp;type. You can define your own primitives similar to the way Ints and Strings are defined.</p>



<p class="wp-block-paragraph">One use case for custom primitives (or Scalars in GraphQL parlance) would be for dealing with dates or with extremely large integers. When defining a new Scalar, you tell the GraphQL implementation how to parse and serialize the new Scalar. This means that you could define a&nbsp;<code class="" data-line="">BigInt</code>&nbsp;which is treated as a string in the client side JavaScript, thus not losing any accuracy.</p>

<p class="wp-block-paragraph">So when building a new product, how do we best experiment with the SDL to create new GraphQL APIs? One example of an SDL first tool is&nbsp;<a href="https://github.com/graphcool/prisma" target="_blank" rel="noreferrer noopener">Prisma</a>. Prisma turns a database into a GraphQL API by letting you design your schema using the GraphQL SDL. This means that there are two APIs, one for the database and one layered on top. Both APIs are able to generate a number of useful methods from the well typed SDL, such as querying for collections.</p>



<p class="wp-block-paragraph">If we take the previous&nbsp;<code class="" data-line="">Blog</code>&nbsp;schema example earlier in this post, we can easily generate a GraphQL API from it. First, we’ll run&nbsp;<code class="" data-line="">prisma init</code>&nbsp;to bootstrap a new API using a full stack boilerplate.</p>



<pre class="wp-block-preformatted">➜ prisma init full-03<br>? How to set up a new Prisma service?Minimal setup: database-only<br>❯ GraphQL server/fullstack boilerplate (recommended)</pre>



<p class="wp-block-paragraph">We will choose the basic node boilerplate for now, but could also start with a more interesting API that includes authentication.</p>



<pre class="wp-block-preformatted">➜ prisma init full-03<br>? How to set up a new Prisma service?Running $ graphql create …<br>? Choose GraphQL boilerplate project:<br>❯ node-basic Basic GraphQL server (incl. database)<br> node-advanced GraphQL server (incl. database &amp; authentication)<br> typescript-basic Basic GraphQL server (incl. database)<br> typescript-advanced GraphQL server (incl. database &amp; authentication)<br> react-fullstack-basic React app + GraphQL server (incl. database )</pre>



<p class="wp-block-paragraph">Then we immediately have to choose where we want to deploy it. In our case, we will use a local Docker cluster (although we could use one of graph.cool’s clusters or deploy a kubernetes pod to handle it as well).</p>



<pre class="wp-block-preformatted">[graphql create] Running boilerplate install script…<br>Running $ prisma deploy…? Please choose the cluster you want to deploy “full-03@dev” to  prisma-eu1 Public development cluster <br>  prisma-us1 Public development cluster <br>❯ local Local cluster (requires Docker)</pre>



<p class="wp-block-paragraph">You may notice that Prisma is a collection of other tools in the ecosystem, so if you like a given piece of Prisma you can pull it out and use it without adopting wholesale.</p>



<p class="wp-block-paragraph">Now that we’ve deployed it, we can see the migrations that happen as a result of our Post type. Notice the seed.graphql import.</p>

<p class="wp-block-paragraph">We can use the&nbsp;<code class="" data-line="">seed.graphql</code>&nbsp;file to populate data in development (for example). The seed file operates on the API that results from our Post SDL so will use migrations to insert data.</p>



<pre class="wp-block-preformatted">mutation {<br>  first: createPost(data: {<br>    title: "Hello World"<br>    text: "This is my first blog post ever!"<br>    isPublished: true<br>  }) {<br>    id<br>  }second: createPost(data: {<br>    title: "My Second Post"<br>    text: "My first post was good, but this one is better!"<br>    isPublished: true<br>  }) {<br>    id<br>  }third: createPost(data: {<br>    title: "Solving World Hunger"<br>    text: "This is a draft..."<br>    isPublished: false<br>  }) {<br>    id<br>  }<br>}</pre>



<p class="wp-block-paragraph">Taking this SDL first approach also allows you to experiment with advanced features like&nbsp;<a href="https://github.com/graphcool/prisma/tree/c9869a4a2135e3b31ca64702e899ac00f3caf71b/examples/subscriptions" target="_blank" rel="noreferrer noopener">subscriptions</a>, which can be a huge pain to implement and manage on the client side and server side without GraphQL.</p>

<p class="wp-block-paragraph">To finish off, I’d like to whet your appetite a little more by pointing out that you can use an SDL file to generate fake data with&nbsp;<a href="https://github.com/APIs-guru/graphql-faker" target="_blank" rel="noreferrer noopener">graphql-faker</a>&nbsp;through an @fake directive. The introspection data can be used for exploration with&nbsp;<a href="https://www.graphqlbin.com/RVIn" target="_blank" rel="noreferrer noopener">graphql-playground</a>. Finally, a client application can extend this approach with&nbsp;<a href="https://www.apollographql.com/docs/link/links/state.html" target="_blank" rel="noreferrer noopener">apollo-link-state</a>&nbsp;to manage local data with Apollo Client, unifying the querying abstractions. As of today, link-state is works with your existing application’s GraphQL schema, rather than allowing a client-only SDL to define its behavior. I’d love to see it support a client-side SDL-based extension mechanism in the future.</p>

<p class="wp-block-paragraph">More and more, we find that GraphQL APIs are being developed by product developers that don’t want to worry about operating backend services.

Real World GraphQL: Talk Videos


<p class="wp-block-paragraph">With GraphQL you can query exactly what you want whenever you want. That is amazing for working with an API, but also has complex security implications. Instead of asking for legitimate, useful data, a malicious actor could submit an expensive, nested query to overload your server, database, network, or all of these. Without the right protections you open yourself up to a DoS (Denial of Service) attack.</p>



<p class="wp-block-paragraph">For example, in our GraphQL API at&nbsp;<a rel="noreferrer noopener" href="https://spectrum.chat/" target="_blank">Spectrum</a>&nbsp;we have a relationship like this:</p>



<pre class="wp-block-prismatic-blocks"><code class="language-graphql" data-line="">type Thread {
  messages(first: Int, after: String): [Message]
}

type Message {
  thread: Thread
}

type Query {
  thread(id: ID!): Thread
}</code></pre>



<p class="wp-block-paragraph">As you can see, you can query both the messages of a thread or the thread of a message. This circular relationship allows a bad actor to construct an expensive nested query like so:</p>



<pre class="wp-block-prismatic-blocks"><code class="language-graphql" data-line="">query maliciousQuery {
  thread(id: &quot;some-id&quot;) {
    messages(first: 99999) {
      thread {
        messages(first: 99999) {
          thread {
            messages(first: 99999) {
              thread {
                # ...repeat times 10000...
              }
            }
          }
        }
      }
    }
  }
}</code></pre>



<p class="wp-block-paragraph">Letting this kind of query through is very bad, since it exponentially increases the amount of objects loaded and will crash your entire server. While there are certain mitigations at other layers which make sending the query in the first place a bit harder (e.g. CORS), they can’t fully prevent it from happening.</p>



<h2 class="wp-block-heading" id="2031"><a href="#size-limiting" aria-hidden="true" class="aal_anchor" id="size-limiting"><svg aria-hidden="true" class="aal_svg" height="16" version="1.1" viewBox="0 0 16 16" width="16"><path fill-rule="evenodd" d="M4 9h1v1H4c-1.5 0-3-1.69-3-3.5S2.55 3 4 3h4c1.45 0 3 1.69 3 3.5 0 1.41-.91 2.72-2 3.25V8.59c.58-.45 1-1.27 1-2.09C10 5.22 8.98 4 8 4H4c-.98 0-2 1.22-2 2.5S3 9 4 9zm9-3h-1v1h1c1 0 2 1.22 2 2.5S13.98 12 13 12H9c-.98 0-2-1.22-2-2.5 0-.83.42-1.64 1-2.09V6.25c-1.09.53-2 1.84-2 3.25C6 11.31 7.55 13 9 13h4c1.45 0 3-1.69 3-3.5S14.5 6 13 6z"></path></svg></a>Size Limiting</h2>



<p class="wp-block-paragraph">A first, naïve approach we considered was to limit the incoming query size by raw bytes. Since the query is sent as a string, a quick length check would suffice:</p>



<pre class="wp-block-prismatic-blocks"><code class="language-javascript" data-line="">app.use(&#039;*&#039;, (req, res, next) =&gt; {
  const query = req.query.query || req.body.query || &#039;&#039;;
  if (query.length &gt; 2000) {
    throw new Error(&#039;Query too large&#039;);
  }
  next();
});</code></pre>



<p class="wp-block-paragraph">Unfortunately, that doesn’t work very well in the real world: the check might allow nasty queries using short field names or block legitimate queries using long field names or nested fragments.</p>

<p class="wp-block-paragraph">A second approach we considered was to have a whitelist of approved queries we use in our own application, and telling the server to not let any query pass except for those.</p>



<pre class="wp-block-prismatic-blocks"><code class="language-javascript" data-line="">app.use(&#039;/api&#039;, graphqlServer((req, res) =&gt; {
  const query = req.query.query || req.body.query;
  // TODO: Get whitelist somehow
  if (!whitelist[query]) {
    throw new Error(&#039;Query is not in whitelist.&#039;);
  }
  /* ... */
}));</code></pre>



<p class="wp-block-paragraph">Maintaining that list of approved queries manually would obviously be a pain, but thankfully the Apollo team created&nbsp;<a rel="noreferrer noopener" href="https://github.com/apollographql/persistgraphql" target="_blank">persistgraphql</a>, which automatically extracts all queries from your client-side code and generates a nice JSON file out of it.</p>



<pre class="wp-block-prismatic-blocks"><code class="language-json" data-line="">{
  &quot;scripts&quot;: {
    &quot;postbuild&quot;: &quot;persistgraphql src api/query-whitelist.json&quot;
  }
}</code></pre>



<p class="wp-block-paragraph">This technique works beautifully and will block all vicious queries reliably. Unfortunately, it also has two major tradeoffs:</p>



<ol class="wp-block-list">
<li><strong>We can never change or delete queries, only add new ones</strong><strong>:</strong>&nbsp;if any user is running an outdated client we can’t just block their request. We’d likely have to keep a history of all queries ever used in production which is a lot more complex.</li>



<li><strong>We cannot open our API to the public:</strong>&nbsp;sometime in the future we’d like to open up our API to the public so that other developers can build their interpretation of what the Spectrum interface could look like. If we only let a whitelist of queries through that severely limits their options already and defeats the point of having a GraphQL API (super flexible system restrained by a synthetic whitelist).</li>
</ol>



<p class="wp-block-paragraph">Those were constraints we couldn’t work with, so we went back to the drawing board.</p>



<h2 class="wp-block-heading" id="66f5"><a href="#depth-limiting" aria-hidden="true" class="aal_anchor" id="depth-limiting"><svg aria-hidden="true" class="aal_svg" height="16" version="1.1" viewBox="0 0 16 16" width="16"><path fill-rule="evenodd" d="M4 9h1v1H4c-1.5 0-3-1.69-3-3.5S2.55 3 4 3h4c1.45 0 3 1.69 3 3.5 0 1.41-.91 2.72-2 3.25V8.59c.58-.45 1-1.27 1-2.09C10 5.22 8.98 4 8 4H4c-.98 0-2 1.22-2 2.5S3 9 4 9zm9-3h-1v1h1c1 0 2 1.22 2 2.5S13.98 12 13 12H9c-.98 0-2-1.22-2-2.5 0-.83.42-1.64 1-2.09V6.25c-1.09.53-2 1.84-2 3.25C6 11.31 7.55 13 9 13h4c1.45 0 3-1.69 3-3.5S14.5 6 13 6z"></path></svg></a>Depth Limiting</h2>



<p class="wp-block-paragraph">One harmful aspect of the malicious query above is the nesting, classified by its&nbsp;<em>depth</em>, which makes the query exponentially more expensive. Each layer adds a lot more work for your backend, which can quickly add up when combined with lists.</p>



<p class="wp-block-paragraph">We looked around and found&nbsp;<a rel="noreferrer noopener" href="https://github.com/stems/graphql-depth-limit" target="_blank">graphql-depth-limit</a>, a lovely module by&nbsp;<a rel="noreferrer noopener" href="https://twitter.com/acarl005" target="_blank">Andrew Carlson</a>, which enables us to easily limit the maximum depth of incoming queries. We checked our client and the deepest query we use has 7 levels, so we went with a (quite lenient) maximum depth of 10 and added it to our validation rules:</p>



<pre class="wp-block-prismatic-blocks"><code class="language-javascript" data-line="">app.use(&#039;/api&#039;, graphqlServer({
  validationRules: [depthLimit(10)]
}));</code></pre>



<p class="wp-block-paragraph">That’s how simple depth limiting is!</p>



<h2 class="wp-block-heading" id="1a60"><a href="#amount-limiting" aria-hidden="true" class="aal_anchor" id="amount-limiting"><svg aria-hidden="true" class="aal_svg" height="16" version="1.1" viewBox="0 0 16 16" width="16"><path fill-rule="evenodd" d="M4 9h1v1H4c-1.5 0-3-1.69-3-3.5S2.55 3 4 3h4c1.45 0 3 1.69 3 3.5 0 1.41-.91 2.72-2 3.25V8.59c.58-.45 1-1.27 1-2.09C10 5.22 8.98 4 8 4H4c-.98 0-2 1.22-2 2.5S3 9 4 9zm9-3h-1v1h1c1 0 2 1.22 2 2.5S13.98 12 13 12H9c-.98 0-2-1.22-2-2.5 0-.83.42-1.64 1-2.09V6.25c-1.09.53-2 1.84-2 3.25C6 11.31 7.55 13 9 13h4c1.45 0 3-1.69 3-3.5S14.5 6 13 6z"></path></svg></a>Amount Limiting</h2>



<p class="wp-block-paragraph">The second harmful aspect of the query above is fetching 99999 of an object. No matter what that object is, fetching a ton of it will always be expensive. (Although the database stress might be mitigated by DataLoader, the network and processing stress won’t)</p>



<p class="wp-block-paragraph">Instead of setting the type of the first argument to Int (which allows any arbitrary number) we have a custom scalar created with&nbsp;<a rel="noreferrer noopener" href="https://github.com/joonhocho/graphql-input-number" target="_blank">graphql-input-number</a>, that restricts the maximum value to 100:</p>



<pre class="wp-block-prismatic-blocks"><code class="language-javascript" data-line="">const PaginationAmount = GraphQLInputInt({
  name: &#039;PaginationAmount&#039;,
  min: 1,
  max: 100,
});</code></pre>



<p class="wp-block-paragraph">This will throw an error, if anybody queries for more than 100 objects. We then use that across our API anywhere we have a connection:</p>



<pre class="wp-block-prismatic-blocks"><code class="language-graphql" data-line="">type Thread {
  messages(first: PaginationAmount, after: String): [Message]
}</code></pre>



<p class="wp-block-paragraph">Now we’ve entirely prevented the malicious query from above! 🎉</p>



<h2 class="wp-block-heading" id="9e7f"><a href="#query-cost-analysis" aria-hidden="true" class="aal_anchor" id="query-cost-analysis"><svg aria-hidden="true" class="aal_svg" height="16" version="1.1" viewBox="0 0 16 16" width="16"><path fill-rule="evenodd" d="M4 9h1v1H4c-1.5 0-3-1.69-3-3.5S2.55 3 4 3h4c1.45 0 3 1.69 3 3.5 0 1.41-.91 2.72-2 3.25V8.59c.58-.45 1-1.27 1-2.09C10 5.22 8.98 4 8 4H4c-.98 0-2 1.22-2 2.5S3 9 4 9zm9-3h-1v1h1c1 0 2 1.22 2 2.5S13.98 12 13 12H9c-.98 0-2-1.22-2-2.5 0-.83.42-1.64 1-2.09V6.25c-1.09.53-2 1.84-2 3.25C6 11.31 7.55 13 9 13h4c1.45 0 3-1.69 3-3.5S14.5 6 13 6z"></path></svg></a>Query Cost Analysis</h2>



<p class="wp-block-paragraph">Unfortunately, there’s still a potential to overwhelm the server under the right conditions: there are certain app-specific queries that are neither too deep nor request too many objects but are still very expensive. For us at Spectrum, such a query could look like this:</p>



<pre class="wp-block-prismatic-blocks"><code class="language-graphql" data-line="">query evilQuery {
  thread(id: &quot;54887141-57a9-4386-807c-ed950c4d5132&quot;) {
    messageConnection(first: 100) { ... }
    participants(first: 100) {
      threadConnection(first: 100) { ... }
      communityConnection { ... }
      channelConnection { ... }
      everything(first: 100) { ... }
    }
  }
}</code></pre>



<p class="wp-block-paragraph">Neither the depth nor the individual amounts are exceptionally high in this query, so it would pass through our current protections. Yet, it potentially fetches tens of thousands of records, meaning it’s intensive on the database, server and network, a worst-case scenario.</p>



<p class="wp-block-paragraph">To prevent this we would need to analyze queries before we run them to calculate their complexity and block them if were too expensive. While this is more work than both of our previous protections, it’ll make 100% sure no malicious query can get to our resolvers.</p>



<p class="wp-block-paragraph"><strong>Before you go ahead and spend a ton of time implementing query cost analysis be certain you need it.</strong>&nbsp;Try to crash or slow down your staging API with a nasty query and see how far you get — maybe your API doesn’t have these kinds of nested relationships, or maybe it can handle fetching thousands of records at a time perfectly fine and doesn’t need query cost analysis!</p>



<p class="wp-block-paragraph">I ran the above query locally on my maxed-out 2017 MacBook Pro and it took our API server a good 10–15 seconds to respond with a megabyte of JSON. We really need it since we never want anybody bombarding our API with that. (<a href="https://developer.github.com/v4/guides/resource-limitations/" target="_blank" rel="noreferrer noopener">The GitHub GraphQL API also uses Query Cost Analysis</a>)</p>



<h3 class="wp-block-heading" id="6723"><a href="#implementing-query-cost-analysis" aria-hidden="true" class="aal_anchor" id="implementing-query-cost-analysis"><svg aria-hidden="true" class="aal_svg" height="16" version="1.1" viewBox="0 0 16 16" width="16"><path fill-rule="evenodd" d="M4 9h1v1H4c-1.5 0-3-1.69-3-3.5S2.55 3 4 3h4c1.45 0 3 1.69 3 3.5 0 1.41-.91 2.72-2 3.25V8.59c.58-.45 1-1.27 1-2.09C10 5.22 8.98 4 8 4H4c-.98 0-2 1.22-2 2.5S3 9 4 9zm9-3h-1v1h1c1 0 2 1.22 2 2.5S13.98 12 13 12H9c-.98 0-2-1.22-2-2.5 0-.83.42-1.64 1-2.09V6.25c-1.09.53-2 1.84-2 3.25C6 11.31 7.55 13 9 13h4c1.45 0 3-1.69 3-3.5S14.5 6 13 6z"></path></svg></a>Implementing Query Cost Analysis</h3>



<p class="wp-block-paragraph">There are a couple of packages on npm to implement query cost analysis. Our two front-runners were&nbsp;<a href="https://github.com/4Catalyzer/graphql-validation-complexity" target="_blank" rel="noreferrer noopener">graphql-validation-complexity</a>, a plug-n-play module, or&nbsp;<a href="https://github.com/pa-bru/graphql-cost-analysis" target="_blank" rel="noreferrer noopener">graphql-cost-analysis</a>, which gives you more control by letting you specify a @cost directive. There’s also&nbsp;<a href="https://github.com/ivome/graphql-query-complexity" target="_blank" rel="noreferrer noopener">graphql-query-complexity</a>, but I wouldn’t recommend choosing it over graphql-cost-analysis since it’s the same idea without directive or multiplier support.</p>



<p class="wp-block-paragraph">We went with&nbsp;<a href="https://github.com/pa-bru/graphql-cost-analysis" target="_blank" rel="noreferrer noopener">graphql-cost-analysis</a>&nbsp;because we have a large discrepancy between our fastest resolvers (20μs) and our slowest ones (10s+), so we needed the control we got from it. That being said, maybe graphql-validation-complexity is enough for you, try it out for sure!</p>



<p class="wp-block-paragraph">The way it works is that you specify the relative cost of resolving a certain field or type. It also has multiplication support, so if you requested a list any nested field within would be multiplied by the pagination amount, which is very neat.</p>



<p class="wp-block-paragraph">This is what the @cost directive looks like in practice:</p>



<pre class="wp-block-prismatic-blocks"><code class="language-graphql" data-line="">type Participant {
  # The complexity of getting one thread in a thread connection is 3, and multiply that by the amount of threads fetched
  threadConnection(first: PaginationAmount, after: String): ThreadConnection @cost(complexity: 3, multipliers: [&quot;first&quot;])
}

type Thread {
  author: Author @cost(complexity: 1)
  participants(first: PaginationAmount,...): [Participant] @cost(complexity: 2, multipliers: [&quot;first&quot;])
}</code></pre>



<p class="wp-block-paragraph">This is just a snippet of our API types, but you get the point. You specify how complex a certain field is, which argument to multiply by and the maximum cost and graphql-cost-analysis does the rest for you.</p>



<p class="wp-block-paragraph">I determined how complex certain resolvers are via the performance tracking data exposed by <a href="https://studio.apollographql.com/signup?referrer=blog">Apollo Studio</a>. I went through the entire schema and assigned a value based on the p99 service time. Then we looked through all the queries on our client to figure out the most expensive one, which got ~500 complexity points. To give us a bit of leeway for the future we set the maximum complexity to 750.</p>



<p class="wp-block-paragraph">Running the evilQuery from above, now that we’ve added graphql-cost-analysis, I get an error message telling me that the “GraphQL query exceeds maximum complexity, please remove some nesting or fields and try again. (max: 750, actual: 1010319)”</p>



<p class="wp-block-paragraph"><strong>1 million complexity points? Rejected!</strong></p>

<p class="wp-block-paragraph">To summarize, I’d recommend using Depth and Amount Limiting as the minimum protection for any GraphQL API — they’re easy to implement and will give ample safety. Depending on your specific security requirements and schema, you might also want to investigate Query Cost Analysis. While it is a bit more work than the other tools, it does provide full coverage in the defense against malicious actors.</p>

Securing Your GraphQL API from Malicious Queries

2017: The year in GraphQL


<p class="wp-block-paragraph">A couple of months ago, we started to use Apollo Client (+React Native) at&nbsp;<a href="https://werkspot.nl/" target="_blank" rel="noreferrer noopener">Werkspot</a>. From the very beginning, Apollo overwhelmed us by the simplicity and flexibility it provides. It inspired us to create our own vision about technology and experiment with various approaches to data fetching that we think are worth sharing.</p>



<p class="wp-block-paragraph">Enjoy the ride! 🚀</p>

<p class="wp-block-paragraph">One of the very powerful concepts that we found for ourselves with Apollo is Query Components. These components are meant to express a domain-specific data logic in a clear, declarative way:</p>



<pre class="wp-block-prismatic-blocks"><code class="language-javascript" data-line="">const QUERY = gql`
  query allCities($country: String!) { 
    allCities { 
      id
      name
    }
  }
`;

class CitiesQuery extends Component {
  render() {
    return this.props.children(this.props.data);
  }
}

export default graphql(QUERY, {
  options: ({ country }) =&gt; ({ variables: { country } }),
})(CitiesQuery);</code></pre>



<p class="wp-block-paragraph"><code class="" data-line="">CitiesQuery</code>&nbsp;component is an oversimplified example of an average Query Component. It exports a&nbsp;<code class="" data-line="">Component</code>, enhanced by a&nbsp;<code class="" data-line="">graphql</code>&nbsp;wrapper for fetching data. After Apollo takes care of fetching and mapping props to query parameters, query component uses “function-as-a-child” approach to expose a child-independent API with injected data.</p>



<p class="wp-block-paragraph">Comparing to the standard approach where you add a&nbsp;<code class="" data-line="">graphql</code>&nbsp;wrapper to your higher-order components, query components have a set of advantages:</p>



<ul class="wp-block-list"><li><strong>Testability</strong>. Unless you have a very good reason, you can test your components without any data management logic.</li><li><strong>Separation of concerns</strong>. From now on, higher-order components are no longer concerned about the way data is fetched/pushed to the server.</li><li><strong>Abstraction over data management layer</strong>. Frankly speaking, it doesn’t really matter which library you use under the hood. Query Components abstracts out your data management layer so you can focus on business logic and change underlying implementation if needed.</li></ul>



<p class="wp-block-paragraph">Once a Query Component is defined, it can be used as any other component in your application:</p>



<pre class="wp-block-prismatic-blocks"><code class="" data-line="">class MapPicker extends PureComponent {
  render() {
    return (
      // ...
      &lt;CitiesQuery country=&quot;Netherlands&quot;&gt;
        {({ allCities }) =&gt; &lt;CitiesList cities={allCities} /&gt;}
      &lt;/CitiesQuery&gt;
      // ...
    );
  }
}</code></pre>



<p class="wp-block-paragraph">A nice side effect of decoupling higher-order components into Query Components is minimizing bloat. If the data management layer grows, it won’t affect presenter components unless they have to reflect new data properties.</p>



<h2 class="wp-block-heading" id="78d8"><a href="#mutations-with-query-components" aria-hidden="true" class="aal_anchor" id="mutations-with-query-components"><svg aria-hidden="true" class="aal_svg" height="16" version="1.1" viewBox="0 0 16 16" width="16"><path fill-rule="evenodd" d="M4 9h1v1H4c-1.5 0-3-1.69-3-3.5S2.55 3 4 3h4c1.45 0 3 1.69 3 3.5 0 1.41-.91 2.72-2 3.25V8.59c.58-.45 1-1.27 1-2.09C10 5.22 8.98 4 8 4H4c-.98 0-2 1.22-2 2.5S3 9 4 9zm9-3h-1v1h1c1 0 2 1.22 2 2.5S13.98 12 13 12H9c-.98 0-2-1.22-2-2.5 0-.83.42-1.64 1-2.09V6.25c-1.09.53-2 1.84-2 3.25C6 11.31 7.55 13 9 13h4c1.45 0 3-1.69 3-3.5S14.5 6 13 6z"></path></svg></a>Mutations with Query Components</h2>



<p class="wp-block-paragraph">Mutations are not that straightforward as queries. When a query component is mounted, Apollo immediately tries to fetch. However, when we talk about mutations, there is no need (in 99% of our cases) to perform any mutations at the mount time. This idea brings us to the point that we should have a way to control a moment when we execute our mutations. For example:</p>



<pre class="wp-block-prismatic-blocks"><code class="" data-line="">const MUTATION = gql`
  mutation (name: String!) {
    createProposal(input: $input) { clientMutationId }
  }
`;

class UserMutation extends Component {
  constructor(props, ctx) {
    super(props, ctx);

    this.execute = () =&gt; this.executeMutation();
  }

  executeMutation() {
    this.props.mutate({
      variables: {
        name: this.props.name
      },
    });
  }

  render() {
    return this.props.children(this.execute);
  }
}

export default graphql(MUTATION)(UserMutation);</code></pre>



<p class="wp-block-paragraph">Therefore, you can use this component in a similar way:</p>



<pre class="wp-block-prismatic-blocks"><code class="" data-line="">class Profile extends PureComponent {
  render() {
    return (
      // ...
      &lt;UserMutation name=&quot;Alexey&quot;&gt;
        {execute =&gt; &lt;Button onPress={execute} /&gt;}

<p class="wp-block-paragraph">So the concept is the same: Query Component receives a bunch of props that are later on used as parameters for the mutation query.</p>

<p class="wp-block-paragraph">When it comes to testing, Apollo-based components have a bunch of features that we need to take into account. The most complicated one is related to React context and Apollo Client reference in particular. All components that intent to use Apollo should be put into the subtree of&nbsp;<code class="" data-line="">&lt;ApolloProvider /&gt;</code>&nbsp;which gives them a reference to the client through the React context. Hopefully, if we use Enzyme and shallow rendering, we can supply context object as one of the options.</p>



<h3 class="wp-block-heading" id="8957"><a href="#assertions" aria-hidden="true" class="aal_anchor" id="assertions"><svg aria-hidden="true" class="aal_svg" height="16" version="1.1" viewBox="0 0 16 16" width="16"><path fill-rule="evenodd" d="M4 9h1v1H4c-1.5 0-3-1.69-3-3.5S2.55 3 4 3h4c1.45 0 3 1.69 3 3.5 0 1.41-.91 2.72-2 3.25V8.59c.58-.45 1-1.27 1-2.09C10 5.22 8.98 4 8 4H4c-.98 0-2 1.22-2 2.5S3 9 4 9zm9-3h-1v1h1c1 0 2 1.22 2 2.5S13.98 12 13 12H9c-.98 0-2-1.22-2-2.5 0-.83.42-1.64 1-2.09V6.25c-1.09.53-2 1.84-2 3.25C6 11.31 7.55 13 9 13h4c1.45 0 3-1.69 3-3.5S14.5 6 13 6z"></path></svg></a>Assertions</h3>



<p class="wp-block-paragraph">One of the very first things we would like to test is that every Query Component is able to produce variables, required by a query. To ensure that, we check a shape of resulting variables.</p>



<p class="wp-block-paragraph">Another assertion that we would like to make is about response shape. In other words, we check if given&nbsp;<code class="" data-line="">data.x</code>&nbsp;complies with the shape of the mock that was passed to the fake client during initialization.</p>



<p class="wp-block-paragraph">And the last, but not least: query component should call a function that we pass as a child with the data pulled from Apollo. Altogether, the test suit looks like this:</p>



<pre class="wp-block-prismatic-blocks"><code class="" data-line="">describe(&#039;CitiesQuery component&#039;, () =&gt; {
  it(&#039;renders children with a query result&#039;, () =&gt; {
    const spy = jest.fn(() =&gt; null);
    const config = {
      context: {
        client: makeFakeClient({
          resolveWith: {
            allCities: allCitiesFixture,
          },
        }),
      },
    };

    shallow(&lt;CitiesQuery country=&quot;Netherlands&quot;&gt;{spy}&lt;/CitiesQuery&gt;, config).render();

    expect(spy).toHaveBeenCalled();
    expect(spy.mock.calls[0][0].variables.country).toEqual(&#039;Netherlands&#039;);
    expect(spy.mock.calls[0][0].allCities).toMatchObject(allCitiesFixture);
  });
});</code></pre>



<p class="wp-block-paragraph">The very last uncovered function is <code class="" data-line="">makeFakeClient</code>. It is a self-written helper that generates an Apollo Client with a fake link:</p>



<pre class="wp-block-prismatic-blocks"><code class="" data-line="">import { ApolloLink, Observable } from &#039;apollo-link&#039;;
import { InMemoryCache } from &#039;apollo-cache-inmemory&#039;;
import ApolloClient from &#039;apollo-client&#039;;

function createMockLink(options) {
  return new ApolloLink(() =&gt;
    new Observable((observer) =&gt; {
      if (!options.fail) {
        observer.next({
          data: options.resolveWith,
        });
        observer.complete();
      } else {
        observer.error(options.failWith);
      }
    }),
  );
}

export default options =&gt; new ApolloClient({
  link: createMockLink(options).request,
  cache: new InMemoryCache(),
});</code></pre>



<p class="wp-block-paragraph">This should be more or less it. I didn’t cover mutation components testing, but it isn’t anyhow different. The only thing I can foresee is an additional assertion that&nbsp;<code class="" data-line="">execute</code>&nbsp;handler triggers Apollo fetcher, but I’ll leave it to the reader.</p>

Query Components with Apollo


<p class="wp-block-paragraph"><em>This is a guest post from Apollo contributor&nbsp;</em><a href="https://medium.com/u/373d9846244b?source=post_page-----cb05aec16325----------------------" target="_blank" rel="noreferrer noopener"><em>James Reggio</em></a><em>, co-founder of&nbsp;</em><a href="http://banter.fm/" target="_blank" rel="noreferrer noopener"><em>Banter</em></a><em>, a podcasting client built with Apollo and React Native.</em></p>



<p class="wp-block-paragraph">First impressions are important, but with mobile apps the second impression is sometimes what counts the most.

<p class="wp-block-paragraph">Whether you’re persisting data with&nbsp;<code class="" data-line="">AsyncStorage</code>&nbsp;or&nbsp;<code class="" data-line="">localForage</code>,&nbsp;<code class="" data-line="">apollo-cache-persist</code>&nbsp;works with a&nbsp;<a href="https://github.com/apollographql/apollo-cache-persist#storage-providers" target="_blank" rel="noreferrer noopener">variety of storage providers</a>&nbsp;for the web and React Native. It also supports any cache that works with Apollo Client 2.0, including the default&nbsp;<code class="" data-line="">&lt;a href=&quot;https://www.npmjs.com/package/apollo-cache-inmemory&quot; target=&quot;_blank&quot; rel=&quot;noreferrer noopener&quot;&gt;InMemoryCache&lt;/a&gt;</code>&nbsp;and&nbsp;<code class="" data-line="">&lt;a href=&quot;https://www.npmjs.com/package/apollo-cache-hermes&quot; target=&quot;_blank&quot; rel=&quot;noreferrer noopener&quot;&gt;Hermes&lt;/a&gt;</code>, a community-built alternative.</p>



<p class="wp-block-paragraph">Best of all, you can get started with just a couple lines of code:</p>



<pre class="wp-block-prismatic-blocks"><code class="language-javascript" data-line="">import { InMemoryCache } from ‘apollo-cache-inmemory’;
import { persistCache } from ‘apollo-cache-persist’;

// Set up your cache.
const cache = new InMemoryCache({...});

// Set up cache persistence.
persistCache({
  cache,
  storage: window.localStorage,
});

// Finish configuring Apollo.</code></pre>



<p class="wp-block-paragraph"><code class="" data-line="">persistCache</code>&nbsp;will immediately restore your cache from storage, and automatically persist it after every update (with a short, configurable, debounce interval).</p>



<p class="wp-block-paragraph">If you need more control over the process, we’ve got you covered. You can instantiate a&nbsp;<code class="" data-line="">&lt;a href=&quot;https://github.com/apollographql/apollo-cache-persist#advanced-usage&quot; target=&quot;_blank&quot; rel=&quot;noreferrer noopener&quot;&gt;CachePersistor&lt;/a&gt;</code>, which offers methods to explicitly extract, restore, purge, and measure the cache, as well as methods to pause and resume the automatic persistence.</p>



<p class="wp-block-paragraph">Have specific storage needs?&nbsp;<code class="" data-line="">apollo-cache-persist</code>&nbsp;is compatible with any storage provider that works with&nbsp;<code class="" data-line="">&lt;a href=&quot;https://www.npmjs.com/package/redux-persist&quot; target=&quot;_blank&quot; rel=&quot;noreferrer noopener&quot;&gt;redux-persist&lt;/a&gt;</code>, so there’s already a&nbsp;<a href="https://github.com/apollographql/apollo-cache-persist#storage-providers" target="_blank" rel="noreferrer noopener">suite of well-tested packages</a>&nbsp;at your disposal, including providers for compression and encryption.</p>

<p class="wp-block-paragraph">The default persistence timing — after every write to the cache — rarely loses data, and performs well in modern browsers. However, in resource-constrained environments like React Native, it’s less than ideal.</p>



<p class="wp-block-paragraph">Your app’s UI typically needs to update in response to a write to the cache, so it’s not the best time to send potentially hundreds of kilobytes over the native bridge. (It takes around 600ms to send 100kb over the bridge to AsyncStorage on an iPhone 6, during which your app will not be responsive to touch.)</p>



<p class="wp-block-paragraph">That’s why we’ve included a <code class="" data-line="">background</code> persistence trigger for React Native, which will persist the cache as soon as your app leaves the foreground. This happens whenever the phone is locked, or whenever the home screen, multitasking view, or another app is activated — all good times for an expensive operation.</p>



<pre class="wp-block-prismatic-blocks"><code class="language-javascript" data-line="">import { InMemoryCache } from ‘apollo-cache-inmemory’;
import { persistCache } from ‘apollo-cache-persist’;
import { AsyncStorage } from ‘react-native’;

// Set up your cache.
const cache = new InMemoryCache({...});

// Set up cache persistence.
persistCache({
  cache,
  storage: AsyncStorage,
  trigger: &#039;background&#039;,
});

// Finish configuring Apollo.</code></pre>



<p class="wp-block-paragraph">I’ve been using the&nbsp;<code class="" data-line="">background</code>&nbsp;persistence trigger in my app,&nbsp;<a href="https://banter.fm/" target="_blank" rel="noreferrer noopener">Banter</a>, for months without any issues.

<p class="wp-block-paragraph">The Apollo community is in the&nbsp;<a href="https://github.com/apollographql/apollo-cache-persist/issues/2" target="_blank" rel="noreferrer noopener">early stages</a>&nbsp;of designing fine-grained cache controls, including the ability to utilize directives and metadata to control cache policy on a per-key basis. In the meantime, we’re limited to persisting and restoring the entire cache, which will cause it to grow over time.</p>



<p class="wp-block-paragraph">In my own usage, I haven’t seen this become a performance problem, even with hundreds of kilobytes in the cache. However, it’s good practice to set a high upper bound on its growth, which you can do with the&nbsp;<code class="" data-line="">maxSize</code>&nbsp;option. When your cache exceeds the size limit, persistence will pause and the cache will be reset upon the next launch of the app. I recommend starting with 500kb (<code class="" data-line="">512000</code>&nbsp;bytes) and tuning from there.</p>



<p class="wp-block-paragraph">For further control, you can setup a background task to periodically reset the cache to contain only your app’s most important data. (On the web, you can use a service worker; on React Native, there’s&nbsp;<a href="https://www.npmjs.com/package/react-native-background-task" target="_blank" rel="noreferrer noopener">react-native-background-task</a>.) The background task would start with an empty cache, query the most important data from your GraphQL API, and then persist. This strategy has the added benefit of ensuring the cache is loaded with fresh data when your app launches.</p>

<p class="wp-block-paragraph">There was a lot of excitement as GraphQL&nbsp;<a href="https://dev-blog.apollodata.com/graphql-schema-stitching-8af23354ac37" target="_blank" rel="noreferrer noopener">schema stitching</a>, a method to combine multiple schemas into a unified API, was unveiled during both the workshop and the conference. Schema stitching shows promise as a way to structure microservices while getting the advantages of a manageable, central API. We had the opportunity to link an external API to the app’s schema built during the training, which was one of the training exercises that attendees were most enthused about.</p>



<p class="wp-block-paragraph">If you’re interested in using microservices with GraphQL, you should check out this talk by Jason Lengstorf from IBM where he speaks about his solution, <a rel="noreferrer noopener" href="https://github.com/gramps-graphql/" target="_blank">GRAMPS</a> (GraphQL Apollo Microservice Pattern Server):</p>

<p class="wp-block-paragraph">With the increased focus on production GraphQL in complex architectures, we saw a lot more interest in understanding what was happening with the GraphQL stack and what it means GraphQL API management at scale:</p>



<ul class="wp-block-list"><li>We noticed in the training that not everyone was using a batching/caching solution for their GraphQL backend. If you aren’t already, we highly recommend&nbsp;<a href="https://github.com/facebook/dataloader" target="_blank" rel="noreferrer noopener">dataloader</a>&nbsp;(or a similar tool in your language of choice if you don’t use JavaScript).</li><li>Apollo proposes a&nbsp;<a href="https://github.com/apollographql/apollo-tracing" target="_blank" rel="noreferrer noopener">GraphQL tracing extension</a>&nbsp;that profiles all of your GraphQL operations, supported by many server implementations.</li><li><a href="https://dev-blog.apollodata.com/introducing-apollo-engine-insights-error-reporting-and-caching-for-graphql-6a55147f63fc" target="_blank" rel="noreferrer noopener">Apollo Engine</a>&nbsp;is a new product tailored for production GraphQL users that offers GraphQL query performance monitoring, error tracking, schema management and data caching.</li></ul>

<p class="wp-block-paragraph">The release of&nbsp;<a href="https://dev-blog.apollodata.com/apollo-client-2-0-5c8d0affcec7" target="_blank" rel="noreferrer noopener">Apollo Client 2.0</a>&nbsp;took the most popular client for GraphQL and made it smaller and more flexible. The network interface is now built from composable links that can not only control network connections, but also retries and errors.</p>



<p class="wp-block-paragraph">Apollo Client can even store state data in the local cache, potentially even displacing Redux for some developers. It also allows a choice of client cache technologies, which should help for mobile adoption.</p>

<p class="wp-block-paragraph">GraphQL Summit was an awesome event — full of great people, great discussions and great discoveries. Let’s continue sharing our passion for GraphQL, discover new best practices, and keep building great applications.</p>



<p class="wp-block-paragraph">We’ve tailored the Advanced GraphQL workshop to this conference, and continue to thanks to attendee feedback. We couldn’t have asked for a better group to work with, and look forward to hopefully doing it again next year.

<p class="wp-block-paragraph">A big thank you to the Apollo team at Meteor Development Group for organizing this second edition of GraphQL Summit and to Lee Byron for doing such an amazing job at MCing the event.</p>

Key Takeaways from GraphQL Summit 2017


<p class="wp-block-paragraph">Yesterday at reInvent,&nbsp;<a href="https://aws.amazon.com/blogs/aws/introducing-amazon-appsync/" target="_blank" rel="noreferrer noopener">Amazon launched AppSync</a>, a new GraphQL service featuring real-time updates and built-in offline support. Managed in the AWS console, AppSync’s GraphQL layer aggregates data from other AWS products such as ElasticSearch and DynamoDB. In your application, you query your GraphQL API with the AppSync Client, available for web and native.</p>



<p class="wp-block-paragraph">The AppSync announcement got a lot of love from the developer community, and it’s easy to see why people are excited about GraphQL! Architecting your application with GraphQL enables you to build complex features quickly by simply describing your data requirements and letting your GraphQL layer take care of the rest.

<p class="wp-block-paragraph">Last month, we officially released&nbsp;<a href="https://dev-blog.apollodata.com/apollo-client-2-0-5c8d0affcec7" target="_blank" rel="noreferrer noopener">Apollo Client 2.0</a>&nbsp;at GraphQL Summit 2017. In addition to making it smaller and faster, one of our main goals was to also make it much more modular.

<p class="wp-block-paragraph">In only a few weeks, the AWS team was able to make complex features like offline support and authentication a reality by extending the Apollo&nbsp;<code class="" data-line="">InMemoryCache</code>&nbsp;and using Apollo Link to customize their network interface. We think this is a testament to the extensibility of Apollo Client and hope their example inspires more teams to experiment with personalizing their GraphQL client. Let’s dive into how AWS accomplished this.</p>



<h3 class="wp-block-heading" id="de54"><a href="#apollo-link-enables-offline-support" aria-hidden="true" class="aal_anchor" id="apollo-link-enables-offline-support"><svg aria-hidden="true" class="aal_svg" height="16" version="1.1" viewBox="0 0 16 16" width="16"><path fill-rule="evenodd" d="M4 9h1v1H4c-1.5 0-3-1.69-3-3.5S2.55 3 4 3h4c1.45 0 3 1.69 3 3.5 0 1.41-.91 2.72-2 3.25V8.59c.58-.45 1-1.27 1-2.09C10 5.22 8.98 4 8 4H4c-.98 0-2 1.22-2 2.5S3 9 4 9zm9-3h-1v1h1c1 0 2 1.22 2 2.5S13.98 12 13 12H9c-.98 0-2-1.22-2-2.5 0-.83.42-1.64 1-2.09V6.25c-1.09.53-2 1.84-2 3.25C6 11.31 7.55 13 9 13h4c1.45 0 3-1.69 3-3.5S14.5 6 13 6z"></path></svg></a>Apollo Link enables offline support</h3>



<p class="wp-block-paragraph">To achieve offline support, the AWS team created a&nbsp;<a rel="noreferrer noopener" href="https://github.com/awslabs/aws-mobile-appsync-sdk-js/blob/254930e3de1211c20bbac3efadf571008826bc32/packages/aws-appsync/src/link/offline-link.js" target="_blank">custom Apollo Link</a>&nbsp;that takes a Redux store augmented by&nbsp;<a rel="noreferrer noopener" href="https://github.com/redux-offline/redux-offline" target="_blank">redux-offline</a>&nbsp;for persistence. This link also queues up any pending mutations and calls to refetch queries when the device is offline and stores them in a Redux subtree to be executed when the device goes back online. Since the AppSync Client is based on Apollo Client, you still get the benefit of optimistic UI responses even if the device is offline when the mutation is fired.</p>

<p class="wp-block-paragraph">One AppSync feature that generated a lot of buzz is its emphasis on real-time data. Under the hood, AppSync’s real-time feature is powered by GraphQL subscriptions. While Apollo bases its subscriptions on WebSockets via&nbsp;<a href="https://github.com/apollographql/subscriptions-transport-ws" target="_blank" rel="noreferrer noopener">subscriptions-transport-ws</a>, subscriptions in GraphQL are actually flexible enough for you to base them on another messaging technology. Instead of WebSockets, AppSync’s subscriptions use MQTT as the transport layer.</p>



<p class="wp-block-paragraph">The AWS team even&nbsp;<a href="https://github.com/awslabs/aws-mobile-appsync-sdk-js/blob/254930e3de1211c20bbac3efadf571008826bc32/packages/aws-appsync/src/link/subscription-handshake-link.js" target="_blank" rel="noreferrer noopener">wrote their own Apollo Link</a>&nbsp;to execute subscriptions over MQTT, which we think is a really cool use case. If you’d like to integrate real-time features into your application in only a few lines of code with Apollo Link,&nbsp;<a href="https://www.apollographql.com/docs/react/features/subscriptions.html#subscriptions-client" target="_blank" rel="noreferrer noopener">please check out our example</a>&nbsp;which serves queries &amp; mutations over HTTP and subscriptions over WebSockets.

<p class="wp-block-paragraph">As one of the biggest specialty retail brands in the world, Express keeps up with both fashion and technology trends. Keeping pace technologically means balancing innovation with performance and security. Overhauling the architecture behind the shopping experience’s key eCommerce pages for&nbsp;<a href="https://www.express.com/" target="_blank" rel="noreferrer noopener">Express.com</a>&nbsp;is no task to be taken lightly.</p>



<p class="wp-block-paragraph">I’m part of the team building a new shopping architecture. Today, Express leverages Adobe Experience Manager (AEM) as the customer-facing experience layer powered by our proprietary APIs built on Oracle’s ATG Web Commerce engine. We wanted to upgrade to a more responsive stack for the website’s experience to be “faster and snappier,” while also being flexible enough to react to changing design trends and customer experience patterns. To meet this goal, we formed a new product development team steeped in Javascript, React, and GraphQL expertise and focused on the product page to introduce a new technical stack.</p>

<p class="wp-block-paragraph">We chose React as our foundational Javascript framework. Since more than 50% of our traffic is mobile, we selected GraphQL, which lets the client-side developer control how much data is flowing to the client. That optimization benefit alone was worth the integration. We considered other data orchestration engines, but GraphQL was selected as the best fit with our familiarity and general community acceptance and knowledge.</p>

<p class="wp-block-paragraph">Since&nbsp;<a href="https://github.com/graphql/graphql-js" target="_blank" rel="noreferrer noopener"><em>graphql-js</em></a>&nbsp;is the reference implementation for a GraphQL server, but isn’t built to scale, we needed a production-tolerant solution. Apollo was new to the team. During GraphQL proof-of-concepting, we decided to explore&nbsp;<a href="https://github.com/apollographql/apollo-server" target="_blank" rel="noreferrer noopener">Apollo Server</a>&nbsp;based on its reputation as being very developer friendly and production ready. Apollo Server adds numerous features on top of that reference implementation, such as error handling and easy-to-understand responses. After selecting Apollo’s GraphQL Server,&nbsp;<a href="https://github.com/apollographql/apollo-client" target="_blank" rel="noreferrer noopener">Apollo Client</a>&nbsp;was an obvious choice. Elegant Apollo Client design choices (like the easy-to-use pagination model) made for a great developer experience as well as an efficient new tool in our tool-set.</p>

<p class="wp-block-paragraph">Now GraphQL helps us move faster in product development. We recently had a scenario calling for a new field to be added to a product response to determine the products category. Our API team estimated two weeks to complete the addition. By simply creating a new resolver, we added the new Boolean value, specifying whether the product ID was one of a special set of 25 products, to the response. Within thirty minutes, everyone who uses that API on our side had access to the new field, instead of it being hidden in a client-side module. We saved two weeks of development time.</p>

<p class="wp-block-paragraph">Early on in our POC we started using&nbsp;<a href="https://www.apollographql.com/engine/" target="_blank" rel="noreferrer noopener">Apollo Engine</a>&nbsp;(previously Apollo Optics) to understand performance of our new stack. During this proof of concept, we wrote a query to get product data which had a large variance in running time. As product developers, Engine helped us understand our backend APIs’ impact on performance. In production we now had the ability to see all the data thanks to Engine. Now we could see all the calls coming to the website and deeper specific traffic data. From a monitoring perspective, we are complementing our traffic and conversion data. We now have a view of how the stack is handling traffic that has illustrated where we need optimization and has provided a more accurate view of scale of traffic and any potential issues.</p>



<p class="wp-block-paragraph">We leverage Akamai to cache our GraphQL queries every 24 hours. Each product on page is seen by Engine once every 24 hours. In Engine we should see a maximum of around 5,000 products if it’s cached properly. However, in Engine we were seeing around 300,000 a day. This called out a caching challenge we are still researching.</p>



<p class="wp-block-paragraph">Another challenge Engine helped identify was backend API return errors. We were alerted to a window of 20-second responses that our API team verified as 503s. Those errors were impacting customer experiences, but we were not aware of them. Once identified we adjusted our integration. In short, Engine has been instrumental in identifying issues across our product architecture to improve the end user experience. It has given us confidence in the entire stack.</p>

<p class="wp-block-paragraph"><em>This is a guest post from&nbsp;</em><a href="https://medium.com/u/cff8a83d5fc3?source=post_page-----f23bd884943e----------------------" target="_blank" rel="noreferrer noopener"><em>Peter Piekarczyk</em></a><em>, technical co-founder and Apollo / React Native guru at&nbsp;</em><a href="https://www.orchard.ai/" target="_blank" rel="noreferrer noopener"><em>Orchard.ai</em></a><em>.</em></p>



<p class="wp-block-paragraph"><a href="https://github.com/peterpme/apollo-tote" target="_blank" rel="noreferrer noopener">Apollo Tote</a>&nbsp;is a declarative React component. Take what you’ve been doing inside your “smart” containers and apply it with JSX! It’s meant to be a simple helper library for your Apollo queries until declarative components are released in Apollo 2.</p>



<blockquote class="wp-block-quote is-layout-flow wp-block-quote-is-layout-flow"><p>I created this because I don’t believe separate components and containers need to be applied everywhere. There are times where I’d prefer to see everything in one, succinct file.</p></blockquote>



<p class="wp-block-paragraph">I came up with the idea for Apollo Tote while working on&nbsp;<a href="https://www.orchard.ai/" target="_blank" rel="noreferrer noopener">Orchard Ai</a>. We’re utilizing&nbsp;<a href="https://www.expo.io/" target="_blank" rel="noreferrer noopener">Expo</a>&nbsp;and&nbsp;<a href="https://apollodata.com/" target="_blank" rel="noreferrer noopener">Apollo</a>&nbsp;to help you stay on top of your relationships &amp; network the same way you do about diet, health and fitness.</p>



<p class="wp-block-paragraph">At the very minimum, give it a query and a few render props:</p>



<pre class="wp-block-preformatted">&lt;ApolloTote<br>    query={`<br>      user {<br>        imageUrl<br>      }<br>    `}<br>    renderLoading={() =&gt; &lt;Avatar.Loading /&gt;}<br>    render={result =&gt; &lt;Avatar imageUrl={result.user.imageUrl /&gt;}<br>/&gt;</pre>



<p class="wp-block-paragraph">Note: Apollo Tote is not meant to be used everywhere. We only support queries for now. That being said, there are places where Apollo Tote shines!</p>

<p class="wp-block-paragraph">Authentication &amp; Authorization have always been a drag, for whatever reason. You’ll save a user token in localStorage, but you start to realize there’s a few cases you need to handle:</p>



<ul class="wp-block-list"><li>A token exists but the user no longer does (this sounds so dark IRL)</li><li>A token exists but has expired</li><li>There is no token (this one’s easy!)</li></ul>



<pre class="wp-block-prismatic-blocks"><code class="language-jsx" data-line="">&lt;ApolloTote
    query={`
      query {
        user {
          id
        }
      }
    `}
    test={data =&gt; !!(data &amp;&amp; data.user &amp;&amp; data.user.id)}

    renderLoading={() =&gt; &lt;App.Loading /&gt;}
    render={() =&gt; &lt;App /&gt;}
/&gt;</code></pre>



<p class="wp-block-paragraph"><code class="" data-line="">renderError, renderLoading, render</code>&nbsp;are all Apollo-specific and map directly to { error, loading, data }.</p>



<p class="wp-block-paragraph"><code class="" data-line="">test, handleFail, handlePass</code>&nbsp;are additional helper methods you can use to test for something specific.</p>



<p class="wp-block-paragraph">In this case I’m testing for&nbsp;<code class="" data-line="">user.id</code>, but you can use it for anything where you might use&nbsp;<code class="" data-line="">branch</code>&nbsp;in Recompose: anything that needs to pass or fail.</p>



<p class="wp-block-paragraph">In this case, I’m dispatching&nbsp;<code class="" data-line="">LOG_IN / LOG_OUT</code>&nbsp;with Redux, but feel free to use an event emitter or call a class method, etc.</p>

<p class="wp-block-paragraph">I like to load a different component when I’m handling error state. My favorite way of doing that is by exporting a&nbsp;<code class="" data-line="">Loading</code>&nbsp;component. This way I don’t have to fk around with any of the styling to get the loading state I’d like. It just works!</p>



<p class="wp-block-paragraph">Apollo Tote makes that super easy for ya by giving you the <code class="" data-line="">renderLoading</code> prop:</p>



<pre class="wp-block-prismatic-blocks"><code class="language-jsx" data-line="">&lt;ApolloTote

<p class="wp-block-paragraph">Apollo Tote &amp; render props are a great option when it comes to working with a complex application structure. While Apollo Tote is around today, a version of it will appear in Apollo 2. I’ll keep the API as similar as I can so when its ready, all you’ll have to do is replace the import!</p>



<p class="wp-block-paragraph">This is an awesome opportunity for the community to help make Apollo 2’s declarative components an awesome experience.</p>

Announcing Speakers & Sessions for GraphQL Summit 2017


<p class="wp-block-paragraph">The last month has been an interesting time in the React and GraphQL communities, with a lot of discussion about different software licenses, patent grants, and patents involved in the GraphQL specification. Today, just a few days after&nbsp;<a href="https://code.facebook.com/posts/300798627056246/relicensing-react-jest-flow-and-immutable-js/" target="_blank" rel="noreferrer noopener">React was relicensed to MIT</a>, I’m excited to report that GraphQL is joining in, and all of these issues can finally be put to rest.</p>



<p class="wp-block-paragraph">Here are today’s new developments in regards to the licensing of Facebook’s GraphQL projects:</p>



<ol class="wp-block-list"><li><strong>The&nbsp;</strong><a href="http://facebook.github.io/graphql/draft/" target="_blank" rel="noreferrer noopener"><strong>GraphQL specification</strong></a><strong>, the document on which all GraphQL implementations are based, has been relicensed under the&nbsp;</strong><a href="http://www.openwebfoundation.org/legal/the-owf-1-0-agreements/owfa-1-0" target="_blank" rel="noreferrer noopener"><strong>Open Web Foundation Agreement (OWFa) v1.0</strong></a><strong>.</strong>This change unambiguously grants all the necessary patent rights to use GraphQL in any setting.</li><li><strong>The&nbsp;</strong><a href="https://github.com/graphql/graphql-js" target="_blank" rel="noreferrer noopener"><strong>GraphQL.js reference implementation</strong></a><strong>, which most JavaScript GraphQL projects are based on, and&nbsp;</strong><a href="https://github.com/facebook/relay" target="_blank" rel="noreferrer noopener"><strong>Relay</strong></a><strong>, are being relicensed under the MIT license.</strong>&nbsp;This is an extremely popular and permissive license used by a huge number of open source projects including React and Apollo.</li></ol>



<p class="wp-block-paragraph">Read the&nbsp;<a href="https://medium.com/@leeb/relicensing-the-graphql-specification-e7d07a52301b" target="_blank" rel="noreferrer noopener">post on the Facebook blog</a>&nbsp;for the official announcement from Lee Byron.</p>



<p class="wp-block-paragraph">This is a critical step forward for the GraphQL community, and underscores the GraphQL team’s commitment to empower as many people as possible to adopt GraphQL. We on the Apollo team are thankful that Lee and the team at Facebook were responsive and communicative throughout the process, and reached what we feel is the best possible outcome very quickly.</p>



<p class="wp-block-paragraph">The team at Apollo knew that patent issues were an open question for many GraphQL and Apollo developers, and finding a constructive resolution to these patent questions had been a top priority of ours for the last several months.</p>



<p class="wp-block-paragraph">Read on for more details about these new licenses.</p>

<p class="wp-block-paragraph">The most important news today is that the GraphQL specification has been relicensed under the OWFa, an open license that allows anyone to use or implement the GraphQL specification without worrying about copyright or patent issues.</p>



<p class="wp-block-paragraph">Essentially, the OWFa license says that anyone using the GraphQL specification automatically gets a grant to any patents that are necessary to the spec. This is a standard license that has also been used by&nbsp;<a href="http://www.openwebfoundation.org/faqs/users-of-owf-agreements" target="_blank" rel="noreferrer noopener">many other specifications</a>&nbsp;that you might have heard of or used, including some versions of the&nbsp;<a href="https://dom.spec.whatwg.org/" target="_blank" rel="noreferrer noopener">Document Object Model (DOM) spec</a>&nbsp;from WHATWG and TypeScript from Microsoft.</p>



<p class="wp-block-paragraph">I’m excited that this new license will make it easy for people to use the specification, contribute to it, and build new GraphQL implementations without any legal concerns.</p>



<h2 class="wp-block-heading" id="aa04"><a href="#mit-license-for-graphql-js" aria-hidden="true" class="aal_anchor" id="mit-license-for-graphql-js"><svg aria-hidden="true" class="aal_svg" height="16" version="1.1" viewBox="0 0 16 16" width="16"><path fill-rule="evenodd" d="M4 9h1v1H4c-1.5 0-3-1.69-3-3.5S2.55 3 4 3h4c1.45 0 3 1.69 3 3.5 0 1.41-.91 2.72-2 3.25V8.59c.58-.45 1-1.27 1-2.09C10 5.22 8.98 4 8 4H4c-.98 0-2 1.22-2 2.5S3 9 4 9zm9-3h-1v1h1c1 0 2 1.22 2 2.5S13.98 12 13 12H9c-.98 0-2-1.22-2-2.5 0-.83.42-1.64 1-2.09V6.25c-1.09.53-2 1.84-2 3.25C6 11.31 7.55 13 9 13h4c1.45 0 3-1.69 3-3.5S14.5 6 13 6z"></path></svg></a>MIT license for GraphQL.js</h2>



<p class="wp-block-paragraph">One other point of concern in the community in the past has been the BSD + patents license that Facebook used for some of its most prominent open source projects. Part of today’s announcement is that GraphQL.js, the reference implementation of the GraphQL spec, is going to be licensed under the&nbsp;<a href="https://en.wikipedia.org/wiki/MIT_License" target="_blank" rel="noreferrer noopener">MIT license</a>. This is a standard permissive license used by a huge number of popular open source projects, including all of the Apollo GraphQL open source tools.</p>



<p class="wp-block-paragraph">This means anyone can use, fork, and build upon GraphQL.js without worrying about the license. Since you’re probably already using multiple open source projects with the MIT license, you can use GraphQL.js with the peace of mind that it comes with exactly the same permissions.</p>



<p class="wp-block-paragraph">This is great news for the Apollo project as well, since many of our tools depend on GraphQL.js, which means developers can now use all Apollo open source tools and dependencies under an MIT license.</p>

<p class="wp-block-paragraph">At Apollo, we believe GraphQL is a big step forward for how people manage data in their applications. That’s why we’ve been working hard for almost two years to make GraphQL better, easier to adopt, and more useful for developers, teams, and companies of all shapes and sizes. One part of that work is building great technology, but the social and legal aspects are just as important.</p>



<p class="wp-block-paragraph">On behalf of the whole team, I’d like to express how excited we are that GraphQL is now in the best possible position to grow and thrive as one of the main tools people use to build software. Now, let’s get back to building cool stuff!</p>

<p class="wp-block-paragraph">GraphQL First, or “schema first”, development is a concept that was unveiled about a year ago when the Apollo Dev team first published an <a rel="noreferrer noopener" href="https://dev-blog.apollodata.com/graphql-first-a-better-way-to-build-modern-apps-b5a04f7121a0" target="_blank">article</a> about it and then described it in detail at <a rel="noreferrer noopener" href="https://summit.graphql.com/" target="_blank">GraphQL Summit</a> in San Francisco:</p>

<p class="wp-block-paragraph">At&nbsp;<a href="https://quri.com/" target="_blank" rel="noreferrer noopener">Quri</a>, we have been betting big on GraphQL since early 2016, and that philosophy was just another “Aha!” moment for us.</p>



<p class="wp-block-paragraph">The concept is rather simple: before starting any implementation, the different stakeholders (usually front-end and back-end developers) look at the UI mockups and how the data would be accessed, and then draft a schema proposal either from scratch or based on the existing types. From there, since the&nbsp;<em>contract</em>&nbsp;is settled,&nbsp;<em>in theory</em>&nbsp;the back-end and front-end teams could work independently.&nbsp;Here are a few key slides from&nbsp;<a href="https://medium.com/u/47b3b199a712?source=post_page-----7bf84b260135----------------------" target="_blank" rel="noreferrer noopener">Danielle Man</a>’s presentation last year that demonstrate that workflow:</p>

<p class="wp-block-paragraph">After a little experimentation at Quri, we were able to introduce a GraphQL-based development workflow that has front-end devs and back-end devs building features in parallel. Read on to see how we got there, and what that workflow looks like in the real world.</p>

<p class="wp-block-paragraph">Since this idea was first introduced, there has been only a&nbsp;<a href="https://www.youtube.com/watch?v=SdWI7XaAeeY" target="_blank" rel="noreferrer noopener">few</a>&nbsp;posts about how GraphQL First works in practice. We tried a few things — one of them was to run a mocked version of our schema with&nbsp;<a href="https://github.com/apollographql/graphql-tools" target="_blank" rel="noreferrer noopener">graphql-tools</a>&nbsp;and a copy of the schema. It didn’t really work since we weren’t able to build a process around it, and we found it hard to keep the&nbsp;<em>copy</em>&nbsp;of the schema in sync with our actual, constantly evolving schema.</p>



<p class="wp-block-paragraph">Most of the mocking solutions we found were in&nbsp;<a href="http://dev.apollodata.com/tools/graphql-tools/mocking.html" target="_blank" rel="noreferrer noopener">javascript</a>. We were able to experiment with them, but it was not a viable option for our development workflow since we use&nbsp;<a href="http://graphql-ruby.org/" target="_blank" rel="noreferrer noopener">graphql-ruby</a>. There wasn’t a common language the back-end and front-end developers could use.</p>

<p class="wp-block-paragraph">About two months ago, my colleague Prasanna found about&nbsp;<a href="https://github.com/APIs-guru/graphql-faker" target="_blank" rel="noreferrer noopener">graphql-faker</a>. It is a CLI tool that allows you to extend an existing schema by specifying its endpoint and then writing the new types in the&nbsp;<a href="https://www.graph.cool/docs/faq/graphql-sdl-schema-definition-language-kr84dktnp0/" target="_blank" rel="noreferrer noopener">GraphQL IDL Language</a>:</p>

<p class="wp-block-paragraph">Being able to proxy an existing endpoint is one thing, but this tool went a step further to make it a great experience. You can:</p>



<ol class="wp-block-list"><li>Run the tool with a simple command</li><li>Extend the types in one tab of the browser</li><li>Switch tabs</li><li>Explore the schema with Graph<em>i</em>QL</li><li>Run queries against it</li><li>Get results with both real data and realistic mocked data (utilizing&nbsp;<a href="https://github.com/Marak/faker.js" target="_blank" rel="noreferrer noopener">faker.js</a>)</li></ol>

<p class="wp-block-paragraph">We experimented with it, and since the results were positive we decided to adopt it and include this tool in our development process.</p>

<p class="wp-block-paragraph">Here’s an overview of how this process operates at Quri. First, we’ve created a GitHub repository named&nbsp;<code class="" data-line="">quri/schema-extensions</code>&nbsp;(I created a public&nbsp;<a href="https://github.com/chollier/schema-extensions" target="_blank" rel="noreferrer noopener">example repository</a>, just fork it!).</p>



<p class="wp-block-paragraph">In there, when either a front-end or back-end developer wants to suggest some changes to the schema, we create a pull-request that adds a&nbsp;<code class="" data-line="">&lt;a href=&quot;https://github.com/chollier/schema-extensions/blob/master/example.faker.graphql&quot; target=&quot;_blank&quot; rel=&quot;noreferrer noopener&quot;&gt;feature.faker.graphql&lt;/a&gt;</code>&nbsp;file. We can then use the normal GitHub review process to provide feedback, approval or ask for some modifications. Both the front-end and back-end teams have to approve the changes for it to be merged and then implemented.</p>



<p class="wp-block-paragraph">Let’s have a look at that development workflow. For that use case, we will assume I’m an engineer looking at some product specifications: we want to add to the user page a profile picture. We should be able to see a thumbnail, and, when clicking on the picture, the full-size image.</p>



<ol class="wp-block-list"><li>First I would create a new extension file&nbsp;<code class="" data-line="">user-avatar.faker.graphql</code>&nbsp;in the repository.</li><li>Then I would run the project:&nbsp;<code class="" data-line="">npm start --open --extend http://localhost:3000/graphql/queries --header &quot;Authorization:Bearer [OAuth token]&quot; ./user-avatar.faker.graphql</code>&nbsp;(This assumes my GraphQL endpoint is running on localhost and has some Authentication requirements.)</li><li>Then we can start writing the type extensions in the browser:</li></ol>

<p class="wp-block-paragraph">4. By switching tab on the left side, I can now visualize these additions in Graph<em>i</em>QL:</p>



<figure class="wp-block-image size-large"><img loading="lazy" decoding="async" width="700" height="490" src="https://apollographql.wpengine.com/wp-content/uploads/2020/03/1_99j1ONtJ6rf2hfQPYl2_eA.png" alt="" class="wp-image-982" srcset="https://wp.apollographql.com/wp-content/uploads/2020/03/1_99j1ONtJ6rf2hfQPYl2_eA.png 700w, https://wp.apollographql.com/wp-content/uploads/2020/03/1_99j1ONtJ6rf2hfQPYl2_eA-300x210.png 300w" sizes="auto, (max-width: 700px) 100vw, 700px" /></figure>



<p class="wp-block-paragraph">5. Finally, I can write a query against this schema:</p>



<figure class="wp-block-image alignfull size-large"><img loading="lazy" decoding="async" width="1024" height="543" src="https://apollographql.wpengine.com/wp-content/uploads/2020/03/1_JlRN9GBxnelL4qkTM7D4ow-1024x543.png" alt="" class="wp-image-981" srcset="https://wp.apollographql.com/wp-content/uploads/2020/03/1_JlRN9GBxnelL4qkTM7D4ow-1024x543.png 1024w, https://wp.apollographql.com/wp-content/uploads/2020/03/1_JlRN9GBxnelL4qkTM7D4ow-300x159.png 300w, https://wp.apollographql.com/wp-content/uploads/2020/03/1_JlRN9GBxnelL4qkTM7D4ow-768x407.png 768w, https://wp.apollographql.com/wp-content/uploads/2020/03/1_JlRN9GBxnelL4qkTM7D4ow-1536x815.png 1536w, https://wp.apollographql.com/wp-content/uploads/2020/03/1_JlRN9GBxnelL4qkTM7D4ow-2048x1086.png 2048w, https://wp.apollographql.com/wp-content/uploads/2020/03/1_JlRN9GBxnelL4qkTM7D4ow-1200x636.png 1200w, https://wp.apollographql.com/wp-content/uploads/2020/03/1_JlRN9GBxnelL4qkTM7D4ow-1980x1050.png 1980w" sizes="auto, (max-width: 1024px) 100vw, 1024px" /><figcaption>Utilizing graphql-faker integration with faker.js I was able to provide a different set of mocked data for the two fields</figcaption></figure>



<p class="wp-block-paragraph">6. The last part of the process would be to open a pull request, ask for feedback, incorporate it, and, when a consensus is reached, merge it. For instance, someone might suggest we use some real world examples:</p>



<pre class="wp-block-prismatic-blocks"><code class="language-graphql" data-line="">type Avatar {
  # The original avatar URL
  originalUrl: String @fake(type:avatarUrl, options: { imageCategory: people })
  # The thumbnail resized to 64x64px
- thumbnail64Url: String @fake(type:imageUrl, options: { imageWidth: 64, imageHeight: 64, randomizeImageUrl: true })
+ thumbnail64Url: String @examples(values: [&quot;http://example.com/image.jpg&quot;, &quot;http://example.com/image2.jpg&quot;])
}</code></pre>



<p class="wp-block-paragraph">There is one gotcha: since it is not possible to override types (you can only extend them) as the schema changes get incrementally worked on, we need the team to make pull requests to remove the types and fields that just got implemented from the&nbsp;<code class="" data-line="">.faker.graphql</code>&nbsp;extension file.</p>

<p class="wp-block-paragraph">With this workflow, not only have we improved our feedback loop by making sure every voice is heard during the design process, but we also got a huge gain in productivity and reduced sequencing: once the API contract is settled, the front-end team can start implementing components without the back-end even having started to implement it.</p>

Server Side Rendering with GraphQL


<p class="wp-block-paragraph">Client developers at Coursera love GraphQL’s flexibility, type-safety, and community of support, and&nbsp;<a href="https://building.coursera.org/blog/2016/11/23/why-ui-developers-love-graphql/" target="_blank" rel="noreferrer noopener">we’ve made</a>&nbsp;<a href="https://speakerdeck.com/jnwng/going-graphql-first" target="_blank" rel="noreferrer noopener">that</a>&nbsp;<a href="https://dev-blog.apollodata.com/graphql-just-got-a-whole-lot-prettier-7701d4675f42" target="_blank" rel="noreferrer noopener">well</a>&nbsp;<a href="https://building.coursera.org/blog/2017/05/11/coursera-engineering-podcast-episode-one/" target="_blank" rel="noreferrer noopener">known</a>.

<p class="wp-block-paragraph">Over the past year, we’ve built tooling to dynamically translate all of our REST APIs to GraphQL, allowing our backend devs to continue writing the APIs they’re familiar with, while giving client developers full access to all of the data through GraphQL.</p>

<p class="wp-block-paragraph">Coursera’s approach to REST APIs was to build&nbsp;<em>resource-based</em>&nbsp;APIs (i.e. an API for courses, an API for instructors, an API for course grades, etc.). These were really easy to build and test, and provided a nice separation of concerns on the backend. However, as our product scaled and the number of APIs grew, we began to face many problems around performance, documentation, and general ease-of-use. On many pages, we found ourselves making four or five round-trips to the server to fetch the data that we needed to render.</p>



<p class="wp-block-paragraph">I still remember the excitement on my team when Facebook first introduced GraphQL — we almost immediately realized how GraphQL could solve a lot of our problems, allowing us to fetch all data in a single roundtrip, and providing structured documentation for our APIs. But as much as we wanted to begin writing GraphQL endpoints for everything and stop using REST on our clients, that wasn’t an option that we were able to consider, because:</p>



<ul class="wp-block-list"><li>At the time, we had over 1,000 different REST endpoints at Coursera (and now we have many more) — even if we wanted to stop using REST entirely, the migration cost to GraphQL would be astronomical.</li><li>All of our backend services use REST APIs for inter-service communication, and we often expose the same API for use in both our backend services and our frontend clients.</li><li>We also have three different clients (web, iOS, and Android), and wanted the flexibility to roll out slowly.</li></ul>



<p class="wp-block-paragraph">After some investigation, we found a great approach to help us get to GraphQL — we decided to add a GraphQL proxy layer on top of our REST APIs. This approach is actually pretty common and has&nbsp;<a href="http://graphql.org/blog/rest-api-graphql-wrapper/" target="_blank" rel="noreferrer noopener">been</a>&nbsp;<a href="https://medium.com/@raxwunter/moving-existing-api-from-rest-to-graphql-205bab22c184" target="_blank" rel="noreferrer noopener">very</a>&nbsp;<a href="http://nordicapis.com/how-to-wrap-a-rest-api-in-graphql/" target="_blank" rel="noreferrer noopener">well</a>&nbsp;<a href="https://0x2a.sh/from-rest-to-graphql-b4e95e94c26b" target="_blank" rel="noreferrer noopener">documented</a>, so I won’t go into details here.</p>

<p class="wp-block-paragraph">Wrapping our REST APIs was a pretty easy process — we built some utilities around making downstream REST calls to fetch data in our resolver, and wrote up some rules around converting our existing models into GraphQL.</p>



<p class="wp-block-paragraph">Our first step was to build a few GraphQL resolvers and then launch a GraphQL server in production to make downstream REST calls to our source endpoints. Once we had this working (using GraphiQL to verify everything), we displayed this data on a demo page that we set up, and within a matter of days were ready to call our GraphQL pilot a success.</p>

<p class="wp-block-paragraph">If there’s one thing I’ve learned from this project though, it’s not to celebrate too early.</p>



<p class="wp-block-paragraph">Our GraphQL server worked perfectly for a few days. But suddenly, right before we were set to demo this page to the team, every GraphQL query started failing. This caught us off guard, because we hadn’t deployed any changes to our GraphQL server since we last verified that it was working.</p>



<p class="wp-block-paragraph">After some investigation, we realized that our downstream course catalog service was rolled back to a previous version due to an unrelated bug, and the schema that we had built in our GraphQL service was now out of sync. We were able to manually update the schema and fix our demo, but we quickly realized then that as our GraphQL schema scaled to 1,000 different resources, backed by over 50 different services, keeping everything up to date was going to be impossible.&nbsp;If you have multiple sources of truth in a microservice architecture, it’s a matter of&nbsp;<em>when</em>, not&nbsp;<em>if</em>&nbsp;they’ll become out of sync.</p>



<h3 class="wp-block-heading" id="81d6"><a href="#automating-the-process" aria-hidden="true" class="aal_anchor" id="automating-the-process"><svg aria-hidden="true" class="aal_svg" height="16" version="1.1" viewBox="0 0 16 16" width="16"><path fill-rule="evenodd" d="M4 9h1v1H4c-1.5 0-3-1.69-3-3.5S2.55 3 4 3h4c1.45 0 3 1.69 3 3.5 0 1.41-.91 2.72-2 3.25V8.59c.58-.45 1-1.27 1-2.09C10 5.22 8.98 4 8 4H4c-.98 0-2 1.22-2 2.5S3 9 4 9zm9-3h-1v1h1c1 0 2 1.22 2 2.5S13.98 12 13 12H9c-.98 0-2-1.22-2-2.5 0-.83.42-1.64 1-2.09V6.25c-1.09.53-2 1.84-2 3.25C6 11.31 7.55 13 9 13h4c1.45 0 3-1.69 3-3.5S14.5 6 13 6z"></path></svg></a>Automating the process</h3>



<p class="wp-block-paragraph">So we went back to the drawing boards, and tried to figure out a cleaner solution to get to a single source of truth — it made sense for us to treat our REST APIs as the source of truth, since they’re what we’re basing our GraphQL schema on. To do this, we’d need to&nbsp;<em>automatically</em>&nbsp;and&nbsp;<em>deterministically</em>&nbsp;build our GraphQL layer, reflecting what was currently running in our architecture, not what we thought was running.</p>



<p class="wp-block-paragraph">Luckily for us (perhaps with a bit of foresight),&nbsp;<a href="https://github.com/coursera/naptime" target="_blank" rel="noreferrer noopener">our REST framework</a>&nbsp;gave us everything that we needed to build this automation layer:</p>



<ul class="wp-block-list"><li>Each service in our infrastructure was able to dynamically provide us with a list of REST resources running on it</li><li>For each of those resources, we could introspect the list of endpoints and arguments (i.e. a course endpoint would have a fetch by id, or lookup by instructor)</li><li>Additionally, we received&nbsp;<a href="https://github.com/linkedin/rest.li/wiki/DATA-Data-Schema-and-Templates" target="_blank" rel="noreferrer noopener">Pegasus Schemas</a>, defined by our&nbsp;<a href="http://coursera.github.io/courier/schemalanguage/" target="_blank" rel="noreferrer noopener">Courier schema language</a>&nbsp;for each model returned</li></ul>



<p class="wp-block-paragraph">Once we discovered the different pieces we’d need to build a GraphQL schema, we set up a task on our GraphQL server to ping every downstream service every five minutes, and request all of that information. We then were able to write a 1:1&nbsp;<a href="https://github.com/coursera/naptime/blob/master/naptime-graphql/src/main/scala/org/coursera/naptime/ari/graphql/schema/FieldBuilder.scala" target="_blank" rel="noreferrer noopener">conversion layer</a>&nbsp;between the Pegasus Schemas and GraphQL types.</p>



<p class="wp-block-paragraph">Next, we simply defined a translation between GraphQL queries and REST requests, using most of the logic from our earlier resolvers, and were able to generate a fully-functioning GraphQL server, never more than five minutes out of date.</p>



<h3 class="wp-block-heading" id="6f00"><a href="#relating-the-resources" aria-hidden="true" class="aal_anchor" id="relating-the-resources"><svg aria-hidden="true" class="aal_svg" height="16" version="1.1" viewBox="0 0 16 16" width="16"><path fill-rule="evenodd" d="M4 9h1v1H4c-1.5 0-3-1.69-3-3.5S2.55 3 4 3h4c1.45 0 3 1.69 3 3.5 0 1.41-.91 2.72-2 3.25V8.59c.58-.45 1-1.27 1-2.09C10 5.22 8.98 4 8 4H4c-.98 0-2 1.22-2 2.5S3 9 4 9zm9-3h-1v1h1c1 0 2 1.22 2 2.5S13.98 12 13 12H9c-.98 0-2-1.22-2-2.5 0-.83.42-1.64 1-2.09V6.25c-1.09.53-2 1.84-2 3.25C6 11.31 7.55 13 9 13h4c1.45 0 3-1.69 3-3.5S14.5 6 13 6z"></path></svg></a>Relating the resources</h3>



<p class="wp-block-paragraph">One of the main reasons we wanted to adopt GraphQL was to fetch all data we needed for a page in a single roundtrip to the server. However, our initial approach only provided a one-to-one mapping between the models returned from our REST APIs and what we returned in GraphQL. Without actually linking our resources together, we’d still end up making just as many GraphQL queries to fetch data as we would while using our REST APIs. While there are definitely developer experience gains that come from fetching data about a user in GraphQL instead of REST, there aren’t actually performance gains if you have to wait for that query to return before fetching more data.</p>



<p class="wp-block-paragraph">Our REST APIs each live in a silo — they don’t need to know about the existence of any other API. However, with GraphQL, models and resources&nbsp;<em>do</em>&nbsp;need to know about each other, and how everything is connected.</p>



<p class="wp-block-paragraph">There’s no way to build the links between resources automatically though, so we defined a simple annotation that developers could add to resources to specify the relations between them. For example, we could say that a course resource should have an instructors field representing the instructors who teach that course. And to fetch those instructors, we should lookup instructors by id, using the instructorIds field already available on the course. We called these “forward relations,” because we knew exactly what instructors to fetch by id.</p>



<p class="wp-block-paragraph">In the case where we wanted to go from one resource to another where there wasn’t an explicit link, we added support to do a reverse lookup to fetch the data — i.e. to get a user’s enrollments on a course, we could call the&nbsp;<code class="" data-line="">byCourseId</code>&nbsp;lookup on the&nbsp;<code class="" data-line="">userEnrollments.v1</code>&nbsp;resource, which could return the matching enrollment data for a given user on a given course.</p>



<p class="wp-block-paragraph">The syntax that we developed looks something like this:</p>



<pre class="wp-block-preformatted">courseAPI.addRelation(<br>  "instructors" -&gt; ReverseRelation(<br>    resourceName = "instructors.v1",<br>    finderName = "byCourseId",<br>    arguments = Map("courseId" -&gt; "$id", "version" -&gt; "$version"))</pre>



<p class="wp-block-paragraph">Once these links were in place, our GraphQL schema began coming together— instead of lots of small data pieces that we could fetch with GraphQL, a web of all Coursera’s data and resources formed.</p>

<p class="wp-block-paragraph">We’ve been running our GraphQL server in production at Coursera for over six months now, and while the road has certainly been bumpy at times, we’re really able to recognize the benefits that GraphQL provides. Developers have an easier time discovering data and writing queries, our site is more reliable due to the additional&nbsp;<a href="https://github.com/apollographql/apollo-codegen" target="_blank" rel="noreferrer noopener">type-safety</a>&nbsp;that GraphQL provides, and pages using GraphQL load data much faster.</p>



<p class="wp-block-paragraph">Just as importantly though, this migration didn’t come at a huge cost of developer productivity. Our frontend developers&nbsp;<em>did</em>&nbsp;have to learn how to use GraphQL, but we didn’t have to rewrite any backend APIs or run complex migrations to begin taking advantage of GraphQL — it was simply available for developers to use as they created new applications.</p>



<p class="wp-block-paragraph">Overall, we’ve been really happy with what GraphQL has provided our developers (and ultimately our users) and are really excited for what’s to come in the GraphQL ecosystem.</p>

<p class="wp-block-paragraph">One of my favorite times of year at the office is when the interns join us for the summer.

<p class="wp-block-paragraph">Shadaj is a senior at Lynbrook High School, and has been programming for a long time. He’s been historically interested in Scala, but was working mostly in JavaScript during his internship. Here’s what he worked on:</p>



<ul class="wp-block-list"><li><strong>Subscriptions tutorial:</strong>&nbsp;Shadaj continued the Full-stack GraphQL tutorial with two steps about subscriptions:&nbsp;<a href="https://dev-blog.apollodata.com/tutorial-graphql-subscriptions-server-side-e51c32dc2951" target="_blank" rel="noreferrer noopener">Server-side</a>&nbsp;and&nbsp;<a href="https://dev-blog.apollodata.com/tutorial-graphql-subscriptions-server-side-e51c32dc2951" target="_blank" rel="noreferrer noopener">client-side</a>.</li><li><strong>Apollo Cache API:&nbsp;</strong>He refactored Apollo Client internals to separate out the internal GraphQL cache implementation behind a clean API. In Apollo Client 2.0, the cache will be completely pluggable, so that people can integrate caches based on different technologies like MobX, and build new features like offline support.&nbsp;<a href="https://github.com/apollographql/apollo-client/pulls?q=is%3Apr+author%3Ashadaj" target="_blank" rel="noreferrer noopener">Check out his PRs to add this support here.</a>&nbsp;There are already people in the community working on alternative cache implementations that will be compatible with Apollo Client 2.0, such as&nbsp;<a href="https://github.com/convoyinc/apollo-cache-hermes" target="_blank" rel="noreferrer noopener">apollo-cache-hermes</a>!</li><li><strong>Scala.js and codegen:&nbsp;</strong>In his spare time, Shadaj implemented a typed wrapper and even GraphQL query code generation for Scala for Apollo Client, which can be used with React and Scala.js.&nbsp;<a href="https://dev-blog.apollodata.com/scala-js-and-apollo-better-together-b066c6b09af4" target="_blank" rel="noreferrer noopener">Read the post here.</a></li></ul>

<p class="wp-block-paragraph">Ramya is a sophomore at MIT studying Electrical Engineering and Computer Science. She joined the Apollo team for the summer to work on tools that could help people be more productive in their work, and boy was she successful! Here’s what she worked on:</p>



<ul class="wp-block-list"><li><strong>Apollo Client Devtools:&nbsp;</strong>First, Ramya started out by learning about Apollo and writing&nbsp;<a href="https://dev-blog.apollodata.com/inspecting-your-graphql-client-in-the-browser-2481f8bcdd55" target="_blank" rel="noreferrer noopener">a post about different use cases for the devtools</a>. The&nbsp;<a href="https://github.com/apollographql/apollo-client-devtools" target="_blank" rel="noreferrer noopener">Apollo Client Devtools</a>&nbsp;allow you to send queries to your server, inspect the queries and mutations on your page, and look at the current state of the cache. Since they were built in a hack week, the original implementation relied on a brittle polling approach that used a lot of resources and even had the potential to lock up your browser. Ramya&nbsp;<a href="https://github.com/apollographql/apollo-client-devtools/pulls?q=is%3Apr+author%3Aramyanaga+is%3Aclosed" target="_blank" rel="noreferrer noopener">rewrote the architecture to use a message-passing approach instead</a>, which was infinitely more efficient and also made the tools more reliable.</li><li><strong>New features for Launchpad:</strong>&nbsp;<a href="https://dev-blog.apollodata.com/introducing-launchpad-the-graphql-server-demo-platform-cc4e7481fcba" target="_blank" rel="noreferrer noopener">Apollo Launchpad</a>&nbsp;is the open source platform for GraphQL server demos. It’s got a ton of&nbsp;<a href="https://github.com/apollographql/launchpad" target="_blank" rel="noreferrer noopener">GraphQL server examples</a>&nbsp;with complete working code that you can edit and download. Ramya dove into the complicated world of modern UI development to refactor the code to use modern libraries like React Router 4, add meta tags with React Helmet for social sharing, and a button to use Prettier to format the code.&nbsp;<a href="https://github.com/apollographql/launchpad/pulls?utf8=%E2%9C%93&amp;q=is%3Apr%20author%3Aramyanaga%20" target="_blank" rel="noreferrer noopener">See her work here.</a></li></ul>

<p class="wp-block-paragraph">Evans is a Master’s degree student at Carnegie Mellon University, studying Electrical and Computer Engineering. He got interested in interning at MDG because of his excitement about the Meteor platform, and got to work on the most futuristic feature of Apollo Client:&nbsp;<a href="https://dev-blog.apollodata.com/apollo-link-the-modular-graphql-network-stack-3b6d5fcf9244" target="_blank" rel="noreferrer noopener">Apollo Link.</a>&nbsp;Here’s more detail about his projects:</p>

<p class="wp-block-paragraph">In just the last year, GraphQL has gone from an open source curiosity to a mainstream technology for professional app developers. Companies like GitHub, Shopify, and Yelp have launched public GraphQL APIs, and even large enterprises have standardized their app development around it.&nbsp;Summit is the answer to your GraphQL FOMO: it’s the best place to learn how companies are using GraphQL in production, check out the future of the technology, and meet the friendly community working to support and advance it.</p>



<blockquote class="wp-block-quote is-layout-flow wp-block-quote-is-layout-flow"><p>New to GraphQL? Get started by&nbsp;<a href="http://graphql.org/" target="_blank" rel="noreferrer noopener">reading the docs</a>,&nbsp;<a href="https://www.graphql.com/" target="_blank" rel="noreferrer noopener">understanding the value proposition</a>, and&nbsp;<a href="https://www.howtographql.com/" target="_blank" rel="noreferrer noopener">doing a tutorial</a>&nbsp;to join a growing number of&nbsp;<a href="http://graphql.org/users" target="_blank" rel="noreferrer noopener">GraphQL users</a>.</p></blockquote>



<p class="wp-block-paragraph">We’re anticipating over 700 attendees this year, including developers from the companies and open source projects leading the GraphQL community today. Summit will feature a single track of technical talks over a full two days, covering everything from GraphQL fundamentals to advanced implementation topics. This year, we’re also including a paid workshop day on October 24th (details TBA) and a kick-off party on October 25th at Bespoke, our conference venue.</p>

<p class="wp-block-paragraph">Last month&nbsp;<a href="https://dev-blog.apollodata.com/introducing-launchpad-the-graphql-server-demo-platform-cc4e7481fcba" target="_blank" rel="noreferrer noopener">we released Apollo Launchpad</a>, a platform to prototype and demo GraphQL servers. Today we are releasing all of the code for Launchpad as&nbsp;<a href="https://github.com/apollographql/launchpad" target="_blank" rel="noreferrer noopener">open source</a>&nbsp;on GitHub!</p>



<p class="wp-block-paragraph">In the Apollo project, we’re committed to building valuable open source tools for GraphQL. One thing that’s new for us is building and maintaining Launchpad as an application, not a library. However, just like the open source libraries maintained by the Apollo community, we see Launchpad as a tool to benefit everyone interested in GraphQL.</p>



<p class="wp-block-paragraph">We’ve already seen Launchpad be an effective tool to help people get started with GraphQL, and we want to take it to the next level.</p>

<p class="wp-block-paragraph">We’ve gotten lots of feedback on how to improve and extend Launchpad in the past month. We’re going to continue to support and improve it, but we think we can go much faster with help from the community. For Launchpad to help as many people as possible, we not only need to have more pads and examples, but also new features.</p>



<p class="wp-block-paragraph">In the Launchpad repository,&nbsp;<a href="https://github.com/apollographql/launchpad/issues" target="_blank" rel="noreferrer noopener">we have created issues</a>&nbsp;where we want your help.

<p class="wp-block-paragraph">We are happy we’re able to open source Launchpad and are really excited to move it forward together with the community!</p>


Launchpad is now open source


<p class="wp-block-paragraph">It’s no secret that the Apollo community thinks GraphQL is the best thing to happen to development since sliced bread. We talk to new teams every week who have gotten huge improvements in their workflow and development speed by adopting GraphQL as their new API layer. So we wanted to create a new resource that can help communicate that excitement and give people the tools to get GraphQL running in production at their organization.</p>



<p class="wp-block-paragraph">That’s where&nbsp;<a href="https://www.graphql.com/" target="_blank" rel="noreferrer noopener">Explore GraphQL</a>&nbsp;comes in.</p>

<p class="wp-block-paragraph">What’s this new site for, and how can you get involved? Let’s dive in.</p>



<h2 class="wp-block-heading" id="fbbc"><a href="#the-case-for-graphql-%f0%9f%92%bc" aria-hidden="true" class="aal_anchor" id="the-case-for-graphql-%f0%9f%92%bc"><svg aria-hidden="true" class="aal_svg" height="16" version="1.1" viewBox="0 0 16 16" width="16"><path fill-rule="evenodd" d="M4 9h1v1H4c-1.5 0-3-1.69-3-3.5S2.55 3 4 3h4c1.45 0 3 1.69 3 3.5 0 1.41-.91 2.72-2 3.25V8.59c.58-.45 1-1.27 1-2.09C10 5.22 8.98 4 8 4H4c-.98 0-2 1.22-2 2.5S3 9 4 9zm9-3h-1v1h1c1 0 2 1.22 2 2.5S13.98 12 13 12H9c-.98 0-2-1.22-2-2.5 0-.83.42-1.64 1-2.09V6.25c-1.09.53-2 1.84-2 3.25C6 11.31 7.55 13 9 13h4c1.45 0 3-1.69 3-3.5S14.5 6 13 6z"></path></svg></a>The case for GraphQL 💼</h2>



<p class="wp-block-paragraph">There are a lot of talks being given at conferences around the world introducing people to GraphQL and getting them excited. Once someone is interested in the technology though, there isn’t a clear place to link them to so they can take the next steps to explore GraphQL’s benefits and try it for themselves. That’s why you’ll see slides at the end of every GraphQL talk with 5–7 links pointing to a variety of resources.</p>



<p class="wp-block-paragraph">Here are two types of resources people often link to:</p>



<ul class="wp-block-list"><li><a href="http://graphql.org/" target="_blank" rel="noreferrer noopener"><strong>GraphQL.org</strong></a>: This is the home of the specification and technical documentation about GraphQL as a technology. It’s a critical resource for the community, but it’s focused on presenting the facts and less about presenting the reasons why to start using GraphQL.</li><li><strong>Tutorials and other learning resources for GraphQL</strong>: These do a great job of introducing people to GraphQL and giving a hands-on experience, but they only work if the reader is already interested in adopting the technology. They usually don’t start with a rundown of why GraphQL is good to use in the first place.</li></ul>



<p class="wp-block-paragraph">We are building Explore GraphQL to tell the whole story of why engineering teams adopt GraphQL, and the value it brings from an organization and business perspective. One of the things we’re trying to focus on are the benefits to development velocity engineers get from GraphQL. People who move some or all of their data into a GraphQL API tell us it’s much easier to build new apps and prototype experiences than ever before, and we want to make that super clear to people considering the technology.</p>



<p class="wp-block-paragraph">We’re excited to hear any ideas you might have about how to make that pitch stronger so newcomers have all the tools they need for a great experience with GraphQL!</p>



<h2 class="wp-block-heading" id="69d4"><a href="#guides-and-best-practices-%f0%9f%93%9a" aria-hidden="true" class="aal_anchor" id="guides-and-best-practices-%f0%9f%93%9a"><svg aria-hidden="true" class="aal_svg" height="16" version="1.1" viewBox="0 0 16 16" width="16"><path fill-rule="evenodd" d="M4 9h1v1H4c-1.5 0-3-1.69-3-3.5S2.55 3 4 3h4c1.45 0 3 1.69 3 3.5 0 1.41-.91 2.72-2 3.25V8.59c.58-.45 1-1.27 1-2.09C10 5.22 8.98 4 8 4H4c-.98 0-2 1.22-2 2.5S3 9 4 9zm9-3h-1v1h1c1 0 2 1.22 2 2.5S13.98 12 13 12H9c-.98 0-2-1.22-2-2.5 0-.83.42-1.64 1-2.09V6.25c-1.09.53-2 1.84-2 3.25C6 11.31 7.55 13 9 13h4c1.45 0 3-1.69 3-3.5S14.5 6 13 6z"></path></svg></a>Guides and best practices 📚</h2>



<p class="wp-block-paragraph">One thing we’ve heard over and over again is that there isn’t enough information about how to go from zero to production with GraphQL. There are lots of “hello world” style tutorials, and examples of building something from scratch, but there aren’t many good in-depth resources for advanced topics.</p>



<p class="wp-block-paragraph">The first version of the website puts together some of the articles we’ve found around the web. They cover getting started with GraphQL and address some production issues like authentication, testing, and more. We hope to rapidly improve this part of the site most with community input and brand new content.</p>



<p class="wp-block-paragraph"><strong>If you have an idea for content that is needed in the community, or are interested in writing content (and get prominent credit as an author), please&nbsp;</strong><a href="mailto:community@graphql.com" target="_blank" rel="noreferrer noopener"><strong>let us know</strong></a><strong>!</strong></p>



<p class="wp-block-paragraph">I already think this page is off to a good start, with a list of difficult-to-find articles in one curated place, but it has limitless potential.</p>

<p class="wp-block-paragraph">The last major part of the site is a list of articles written by companies who have adopted GraphQL in production and gotten great results.</p>

<p class="wp-block-paragraph">It’s inspiring to see how many people have already gotten value out of GraphQL on an organizational level, and it’s one of the main things that gives developers the confidence to push for it at their company. We hope that an actively curated list on the new Explore GraphQL website will make it easier to find great examples of GraphQL success stories.</p>

<p class="wp-block-paragraph">After talking to lots of people at the excellent&nbsp;<a href="https://graphql-europe.com/" target="_blank" rel="noreferrer noopener">GraphQL Europe</a>&nbsp;conference, we were convinced that the world needed a clear set of GraphQL resources to help people learn about GraphQL, test it out in their organization, convince their colleagues of its value, and implement it in production. We worked hard to create this first version of Explore GraphQL as a first step towards that goal, but it’s just the initial version.</p>



<p class="wp-block-paragraph">First, we want to expand the set of best practices, production guides, and success stories available. There just aren’t enough resources around the internet, so we’ll be creating a list of articles that need to be written which we think will be important to people learning GraphQL — hope to share this with the community soon! We’ve been writing these articles as fast as we can (mostly here on the blog), but the whole community will need to pull together to create a complete story to get people from zero to production.</p>



<p class="wp-block-paragraph">Then, we want to significantly improve the landing page to tell the best possible story about why people do (and should) adopt GraphQL, by talking to as many people as we can to learn what the technology has done for them. We want to put together a message that resonates with frontend developers, backend administrators, product managers, architects, and everyone else.</p>



<p class="wp-block-paragraph">Long story short, Explore GraphQL is going to be an ever-improving resource and I’m excited to work on it together with you all!</p>


Introducing Explore GraphQL


<p class="wp-block-paragraph">We’ve all seen the&nbsp;<code class="" data-line="">prettier</code>&nbsp;<a href="https://github.com/prettier/prettier#ride-the-hype-train" target="_blank" rel="noreferrer noopener">hype train</a>&nbsp;(and a lot of us are on it!) and while it began as an opinionated code formatter for JavaScript, it has quickly grown to take on other languages like Flow, Typescript, and CSS. As of&nbsp;<code class="" data-line="">prettier@v1.5.0</code>, it now supports one of my favorites,&nbsp;<a href="http://graphql.org/" target="_blank" rel="noreferrer noopener">GraphQL</a>!</p>



<p class="wp-block-paragraph">Let’s let the GIF do the talking:</p>

<p class="wp-block-paragraph">Using&nbsp;<code class="" data-line="">prettier</code>&nbsp;for GraphQL is more than just hitting the “prettify” button in GraphiQL — it’ll take into account things like maximum line-width, whether or not you like commas in your queries, breaking up long lists of arguments on to their own lines, and even works on queries embedded in your JavaScript.</p>



<p class="wp-block-paragraph">If you haven’t given it a try, its&nbsp;<a href="https://github.com/prettier/prettier#usage" target="_blank" rel="noreferrer noopener">really easy to get started</a>; soon you’ll realize you and your team will stop having to nitpick things like spaces, braces, and commas and can focus on basking in the sweet glory of GraphQL!</p>

<p class="wp-block-paragraph">GraphQL support didn’t just happen overnight, though.

GraphQL just got a whole lot “Prettier”!


<p class="wp-block-paragraph"><em>This is a guest post from Kurtis Kemple, tech lead on the UI team&nbsp;</em><a href="https://twitter.com/MLS" target="_blank" rel="noreferrer noopener"><em>@MLS</em></a><em>.</em></p>



<p class="wp-block-paragraph">All jokes aside,&nbsp;<code class="" data-line="">&lt;a href=&quot;http://dev.apollodata.com/react/&quot; target=&quot;_blank&quot; rel=&quot;noreferrer noopener&quot;&gt;react-apollo&lt;/a&gt;</code>&nbsp;is an amazing tool that allows you to solve some really hard data fetching problems with very minimal code. It integrates very easily with existing and greenfield apps&nbsp;<em>and&nbsp;</em>supports Redux integration. If you want to use GraphQL, it’s a tool that I highly recommend investigating.</p>



<p class="wp-block-paragraph">Over the last few months at&nbsp;<a href="https://labs.mlssoccer.com/" target="_blank" rel="noreferrer noopener">Major League Soccer</a>, we have been working a lot with GraphQL/Apollo and have discovered some really interesting tricks (and things that aren’t exactly “tricks”, but are still pretty awesome) you can use to solve some of the more common data fetching/handling issues in building highly dynamic applications. Here are our top five, along with code examples showing how they work.</p>

<p class="wp-block-paragraph">A problem that most developers face is fetching paginated data. React-apollo makes this a pretty trivial thing with the <code class="" data-line="">fetchMore</code> method off of the <code class="" data-line="">data</code> prop. This method allows you to repeat the same query with new variables and then alter the original response, adding the new results to the old.</p>

Conditional Data Fetching</h2>



<p class="wp-block-paragraph">There may be times when you only want to fetch data if some requirements are met — for example, one case might be offering more functionality for desktop users. We can accomplish things like this by using the <code class="" data-line="">&lt;a rel=&quot;noreferrer noopener&quot; href=&quot;http://dev.apollodata.com/react/higher-order-components.html#compose&quot; target=&quot;_blank&quot;&gt;compose&lt;/a&gt;</code> higher order component that <code class="" data-line="">react-apollo</code> provides in conjunction with the <code class="" data-line="">skip</code> config property. The <code class="" data-line="">skip</code> property allows you to tell <code class="" data-line="">react-apollo</code> to skip queries based on certain parameters (in most cases based on the props passed to the component).</p>

At MLS we faced an issue where we wanted to display a match timeline if there were no highlights available.

Polling</h2>



<p class="wp-block-paragraph">At MLS we decided to move away from real-time push in favor of polling for a number of reasons, but a big driving factor was moving to GraphQL. Once we saw how easy it was to fine-tune data fetching in <code class="" data-line="">react-apollo</code> via the <code class="" data-line="">pollInterval</code> option on the config object, we knew we would easily be able to achieve that real-time feel that is necessary for our industry.</p>

Building React Apps with GraphQL, Graphcool & Apollo


<p class="wp-block-paragraph"><a href="http://summit.graphql.com/2016/" target="_blank" rel="noreferrer noopener">Last year</a>&nbsp;on October 26, 2016, 350 developers packed&nbsp;<a href="http://thepearlsf.com/" target="_blank" rel="noreferrer noopener">the Pearl</a>&nbsp;in San Francisco to hear leaders at Facebook, Coursera, Shopify, GitHub, and more speak at the world’s first conference dedicated entirely to GraphQL.</p>



<p class="wp-block-paragraph">We were so thrilled by the level of excitement for the GraphQL technology and ecosystem that the team at Apollo decided to make&nbsp;<a href="http://summit.graphql.com/" target="_blank" rel="noreferrer noopener">this year’s conference</a>&nbsp;longer, bigger, and more focused on the technical questions GraphQL adopters are eager to explore. You will hear from developers and engineering leaders using GraphQL in large, production applications, as well as those at the forefront of the community building the services and open source tools to make that possible.</p>

<p class="wp-block-paragraph">The Neo4j team is happy to be sponsoring and attending GraphQL Europe this year. At Neo4j we’re very excited to see the GraphQL community taking off as developers adopt a new way of building APIs.</p>



<p class="wp-block-paragraph">That’s why today we’re announcing the&nbsp;<strong>Neo4j GraphQL Community Graph Hackathon</strong>. It’s open to anyone, anywhere, but we’ll be helping folks get started at our booth during GraphQL Europe.</p>



<p class="wp-block-paragraph">The hackathon runs now through Monday May 22nd. All valid submissions will receive a Neo4j tshirt, but only the first 15 participants who submit a valid submission will receive a prize of one set of Apple Airpods (or equivilent value Amazon gift certificate). See details below for how to get started.</p>

<p class="wp-block-paragraph">No matter where you are active, your contributions should be visible.</p>

Announcing The Neo4j GraphQL Community Graph Hackathon


<p class="wp-block-paragraph">It’s going to be a huge week in the GraphQL community with GraphQL Europe, the first ever European GraphQL conference! So we’re hitting the road and stopping by several cities and events to give some talks and connect with the community. We hope to see you there!</p>

The Apollo Team Goes to Europe!


<p class="wp-block-paragraph">It’s not often the best engineering decision to use the “coolest new thing”. It’s almost universally agreed upon that the smart thing to do is to rely on time-tested and stable technologies. With regards to a web or mobile backend, the sage advice is to use a relational database, build RESTful APIs, and in general just use things that everybody knows and understands; “Keep it simple” is the agreed upon mantra.</p>



<p class="wp-block-paragraph">At&nbsp;<a href="https://expo.io/" target="_blank" rel="noreferrer noopener">Expo</a>, we diligently follow the “keep it simple” rule. Being a small startup, we have a lot of projects and not many people, and it’s important that we focus on shipping features. That being said, we strongly believe in evaluating technologies, both new and old, by their merits and flaws, over adhering a particular dogma.</p>



<p class="wp-block-paragraph"><a href="http://graphql.org/" target="_blank" rel="noreferrer noopener">GraphQL</a>&nbsp;and the&nbsp;<a href="http://dev.apollodata.com/" target="_blank" rel="noreferrer noopener">Apollo</a>&nbsp;toolchain were choices that we evaluated not by their GitHub star count or release dates, but by how effective we felt they would be in helping our small team build and iterate on our products: They allow for quick, reliable iteration, and an intuitive way to bridge the gap between back-end and front-end development. There’s a multitude of examples of large companies&nbsp;<a href="http://graphql.org/users/" target="_blank" rel="noreferrer noopener">using GraphQL</a>&nbsp;and Apollo in production, but this stack is just as powerful for a company the size of Expo. The tools continue to prove their worth, and are definitely examples of a time when choosing the cool new thing paid off.</p>

<p class="wp-block-paragraph">At the end of 2016, one of Expo’s main internal goals was revamping our&nbsp;<a href="https://expo.io/tools#mobile" target="_blank" rel="noreferrer noopener">client</a>&nbsp;app, a project we affectionately call “Expo Home”.</p>



<p class="wp-block-paragraph">The previous version of the app was basically&nbsp;<em>just</em>&nbsp;an Expo project viewer. You could view your recent projects but couldn’t view someone’s profile with the projects they’d worked on.</p>

<p class="wp-block-paragraph">Besides a nice visual facelift (pictured below), our goal with the new version of the client was to make it much more community-oriented. We have sign in/sign up, user profiles, a way to explore “featured”, “new”, and “top” projects, and project/user search. We have much more planned for Expo Home in the future, but these features are what we agreed would be our MVP, for launch in February 2017.</p>

<p class="wp-block-paragraph">Prior to starting the project, we had some, but not all, of the necessary data available through a myriad of RESTful-ish endpoints exposed by our backend, which we had used in other ancillary parts of our products. In addition to not exposing the data we needed and not being well documented, this part of our codebase also wasn’t very well tested or maintained. We didn’t want to build the future of the Expo client on these shaky foundations, so we had two options —<strong>&nbsp;rearchitect and build out a more maintainable RESTful API, or take a different approach altogether.</strong></p>



<p class="wp-block-paragraph">Prior to working at Expo, I had the opportunity to work on a few apps that used GraphQL and Relay, and was very impressed with the outcome, and was particularly enthusiastic about GraphQL. As the backend engineer on this project, I thought it would be a great idea to try GraphQL for Expo Home, and use Apollo on the frontend.</p>



<p class="wp-block-paragraph">We had a ton of new features to build, and I had wanted to introduce GraphQL into the Expo tech stack for a while. This project seemed like the perfect fit, but I needed to sell it to my team.</p>

<p class="wp-block-paragraph"><a href="https://medium.freecodecamp.com/so-whats-this-graphql-thing-i-keep-hearing-about-baf4d36c20cf" target="_blank" rel="noreferrer noopener">Lots</a>&nbsp;<a href="https://medium.freecodecamp.com/give-it-a-rest-use-graphql-for-your-apis-40a2761e6336" target="_blank" rel="noreferrer noopener">has</a>&nbsp;<a href="https://0x2a.sh/from-rest-to-graphql-b4e95e94c26b" target="_blank" rel="noreferrer noopener">been</a>&nbsp;<a href="https://dev-blog.apollodata.com/the-business-case-for-graphql-cc7a2b93148d" target="_blank" rel="noreferrer noopener">written</a>&nbsp;about GraphQL vs REST, as well as about the problems REST APIs often face. I presented some of these arguments to the team while pitching them on using GraphQL to power Expo Home.</p>



<p class="wp-block-paragraph">Building a performant, maintainable, RESTful application is absolutely possible. Doing it quickly, on the other hand, is another story. We had less than two months to ship the first version of the new Expo mobile app, and thus working quickly was important.</p>



<p class="wp-block-paragraph">Engineering, as with most other things in life, is about tradeoffs. Some considerations I posed to the team:</p>



<ul class="wp-block-list"><li>User experience — If we spend a ton of time making our data fetching logic in the app really robust, are we sacrificing the user experience of our app and polish around UI?</li><li>Performance and stability — If we spend a ton of time on UI polish, are we making a slow app, or one that doesn’t gracefully handle failure?</li><li>Over-fetching — On the backend, we could spend our time focusing on API coverage, and making sure that every last thing that a front-end engineer could ever think of doing is covered by the APIs. If we did that, however, are we building slow endpoints (by providing too much data) or are we causing a request waterfall from our clients because they have to request many API resources to build the UI for a single screen?</li><li>Tech debt— What if we spend time building individual, bespoke APIs that provide perfect coverage for a given screen with no over or under-fetching? Are we backing ourselves into an implementation corner, making everything difficult to manage when we want to add a feature?</li></ul>



<p class="wp-block-paragraph">With GraphQL and Apollo, we didn’t have to make these same tradeoffs and could build a fast and easy-to-maintain front-end and back-end from the outset of the project.</p>

<p class="wp-block-paragraph">In web and mobile development, it’s common practice to build some UI with mock data before integrating with any APIs/services. This workflow allows both back-end and front-end developers to work mostly in parallel.</p>



<p class="wp-block-paragraph">But eventually it’s time to bring in real data. This process will typically be a carefully coordinated dance between front-end and back-end engineers, as each person (or team) finds places where they misjudged the other. Even if a careful spec is put in place beforehand, there will almost certainly be constant back-and-forth.</p>



<p class="wp-block-paragraph">In our case, it was imperative that with the short timeline&nbsp;<a href="https://medium.com/u/d5a707474bd2?source=post_page-----4c1f21f0f115----------------------" target="_blank" rel="noreferrer noopener">Brent Vatne</a>&nbsp;and I could work in parallel as much as possible. As I look back on building the new version of the Expo app, the part that sticks out to me the most is how smooth the workflow was as&nbsp;<a href="https://medium.com/u/d5a707474bd2?source=post_page-----4c1f21f0f115----------------------" target="_blank" rel="noreferrer noopener">Brent Vatne</a>&nbsp;and I worked on the app.</p>



<p class="wp-block-paragraph">Brent and I had almost none of this forced collaboration. This was due to two things:</p>



<ol class="wp-block-list"><li>Apollo and its surrounding tooling makes it trivial to use mock data/a mock server, which we leveraged from the beginning of the project.</li><li><a href="https://github.com/graphql/graphiql" target="_blank" rel="noreferrer noopener">Graph<em>i</em>QL</a>&nbsp;the in-browser IDE for exploring GraphQL servers (pictured below) is simply an amazing tool for browsing an API and discovering its capabilities.</li></ol>



<p class="wp-block-paragraph">Instead of spending time discussing API design or what data should be in which endpoint, Brent and I were able to talk about how to make the product better and provide a great user experience.</p>

<p class="wp-block-paragraph">Another thing that sticks out to me about the GraphQL/Apollo development experience is that at the end of the day, you’re not left with something that was easy to get started with but doesn’t fulfill production needs. It’s quite the opposite — everything we built, because we leveraged the Apollo toolchain and followed GraphQL best-practices, was production-ready from the get-go.</p>

<p class="wp-block-paragraph">Expo Home is far from complete — we have tons of planned improvements for 2017.</p>



<p class="wp-block-paragraph">An example of one such improvement is a feature that shows the current project you have open in&nbsp;<a href="https://github.com/expo/xde" target="_blank" rel="noreferrer noopener">XDE</a>, our desktop developer environment, on the main screen of Expo Home. There are a few moving pieces to this feature, but one of the parts I’m most excited about is leveraging GraphQL subscriptions to update the app front-end.</p>



<p class="wp-block-paragraph">Apollo’s&nbsp;<code class="" data-line="">graphql-tools</code>&nbsp;<a href="https://github.com/apollographql/graphql-tools" target="_blank" rel="noreferrer noopener">package</a>&nbsp;makes this pretty simple to do, and we can leverage&nbsp;<a href="https://www.pubnub.com/" target="_blank" rel="noreferrer noopener">PubNub</a>&nbsp;as the backend, alleviating us from implementing our own WebSocket-based solution.</p>



<figure class="wp-block-image size-large"><img loading="lazy" decoding="async" width="1024" height="324" src="https://apollographql.wpengine.com/wp-content/uploads/2020/03/1_qnhgSmEcAq9X-nSip0nMNA-1024x324.png" alt="" class="wp-image-1114" srcset="https://wp.apollographql.com/wp-content/uploads/2020/03/1_qnhgSmEcAq9X-nSip0nMNA-1024x324.png 1024w, https://wp.apollographql.com/wp-content/uploads/2020/03/1_qnhgSmEcAq9X-nSip0nMNA-300x95.png 300w, https://wp.apollographql.com/wp-content/uploads/2020/03/1_qnhgSmEcAq9X-nSip0nMNA-768x243.png 768w, https://wp.apollographql.com/wp-content/uploads/2020/03/1_qnhgSmEcAq9X-nSip0nMNA-1200x380.png 1200w, https://wp.apollographql.com/wp-content/uploads/2020/03/1_qnhgSmEcAq9X-nSip0nMNA.png 1264w" sizes="auto, (max-width: 1024px) 100vw, 1024px" /></figure>



<p class="wp-block-paragraph">At Expo, we’re also working on bringing pieces of the Expo Home experience to web. All of Expo Home’s backend work, in addition to a reasonable amount of front-end work, can be reused in this effort. And as Expo grows, and we need to move pieces of our infrastructure out of our monolith and into some individual services, the web and mobile clients can stay untouched, allowing us to move quickly in all parts of our infrastructure without blocking any particular team or project.</p>



<p class="wp-block-paragraph">It’s rare to find a technology that is valuable to both the enterprise and the ten person company. GraphQL can help the 5000 person organization wrangle their 1000’s of REST APIs and services into a coherent, discoverable schema and interface, but it can also help the small startup foster good communication patterns between their back-end and front-end developers, enable better parallel work, and provide a solid basis for future API and feature development.</p>



<p class="wp-block-paragraph">GraphQL and the Apollo toolchain have already been instrumental in our product roadmap in 2017, and we’ve only scratched the surface of their overall potential.</p>

<p class="wp-block-paragraph">The standard GraphiQL library already supports passing in a fetcher that returns an observable&nbsp;<em>or</em>&nbsp;promise. That means that anyone can configure it with their own transport, even if it supports multiple results. We’ve already done that for you, using a new<code class="" data-line="">&lt;a href=&quot;https://github.com/apollographql/GraphiQL-Subscriptions-Fetcher&quot; target=&quot;_blank&quot; rel=&quot;noreferrer noopener&quot;&gt;graphql-subscriptions-fetcher&lt;/a&gt;</code>, so you don’t have to.</p>



<p class="wp-block-paragraph">The following steps are all you need to do. (We’re using&nbsp;<code class="" data-line="">graphql-server-express</code>&nbsp;for the example.)</p>



<p class="wp-block-paragraph">First, make sure you have the latest&nbsp;<code class="" data-line="">graphql-server-express</code>&nbsp;package:</p>



<pre class="wp-block-preformatted">npm install —-save graphql-server-express</pre>



<p class="wp-block-paragraph">Now, all you need to do is to set a new field we added to&nbsp;<code class="" data-line="">graphqlExpress</code>&nbsp;config, called&nbsp;<code class="" data-line="">subscriptionsEndpoint</code>, with the Websocket URL subscriptions endpoint (this is the same endpoint you use in your&nbsp;<code class="" data-line="">SubscriptionClient</code>). For example:</p>



<pre class="wp-block-preformatted">app.use(‘/graphiql’, graphiqlExpress({<br>  endpointURL: ‘/graphql’,<br>  subscriptionsEndpoint: `ws://localhost:3000/subscriptions`,<br>}));</pre>



<p class="wp-block-paragraph">That’s it! Finally, all you have to do is start your server, open your browser in&nbsp;<a href="http://api.githunt.com/graphiql" target="_blank" rel="noreferrer noopener">http://localhost:3000/graph<em>i</em>ql</a>, write a GraphQL subscriptions query inside, and the published data from the server will be pushed into your Graph<em>i</em>QL client and displayed in the result screen of Graph<em>i</em>QL.</p>



<blockquote class="wp-block-quote is-layout-flow wp-block-quote-is-layout-flow"><p>This example uses GraphQL server with express — but it also works with graphql-server-hapi, Koa, Restify and Lambda. Just add the&nbsp;<code class="" data-line="">&lt;em&gt;subscriptionsEndpoint&lt;/em&gt;</code>&nbsp;field to your GraphiQL configuration and you are good to go! You can also check out the live GitHunt example&nbsp;<a href="http://api.githunt.com/graphiql" target="_blank" rel="noreferrer noopener">here</a>.</p></blockquote>

<p class="wp-block-paragraph">We added the new Graph<em>i</em>QL subscriptions support to&nbsp;<a href="http://dev.apollodata.com/tools/graphql-server/index.html" target="_blank" rel="noreferrer noopener">graphql-server</a>&nbsp;by default, but in case you’re not using it, it’s still very easy to add that support to your own server.</p>



<p class="wp-block-paragraph">Graph<em>i</em>QL is usually served as static HTML (<a href="https://github.com/apollographql/graphql-server/blob/master/packages/graphql-server-module-graphiql/src/renderGraphiQL.ts#L39" target="_blank" rel="noreferrer noopener">here’s how we do it in graphql-server</a>), so first you need to load&nbsp;<code class="" data-line="">&lt;a href=&quot;https://github.com/apollographql/subscriptions-transport-ws&quot; target=&quot;_blank&quot; rel=&quot;noreferrer noopener&quot;&gt;subscriptions-transport-ws&lt;/a&gt;</code>&nbsp;and&nbsp;<code class="" data-line="">&lt;a href=&quot;https://github.com/apollographql/GraphiQL-Subscriptions-Fetcher&quot; target=&quot;_blank&quot; rel=&quot;noreferrer noopener&quot;&gt;graphql-subscriptions-fetcher&lt;/a&gt;&nbsp;</code>inside the&nbsp;<code class="" data-line="">&lt;head&gt;</code>&nbsp;tag. We’ve published the transport client so that it’s easy to use in a script tag from&nbsp;<a href="https://unpkg.com/" target="_blank" rel="noreferrer noopener">Unpkg</a>:</p>



<pre class="wp-block-preformatted">&lt;script src=”//unpkg.com/subscriptions-transport-ws@0.5.4/browser/client.js”&gt;&lt;/script&gt;&lt;script src="//unpkg.com/graphiql-subscriptions-fetcher@0.0.2/browser/client.js"&gt;&lt;/script&gt;</pre>



<p class="wp-block-paragraph">Next, you need to create a&nbsp;<code class="" data-line="">SubscriptionClient</code>&nbsp;with your subscriptions endpoint:</p>

How to Use Subscriptions in GraphiQL

What’s Next.js for Apollo


<p class="wp-block-paragraph">It’s been so fun to be working with the community on the Apollo project for the last year. There have already been dozens of blog posts, meetup talks, announcements, events, and more! Now that we’re headed for a&nbsp;<a href="https://dev-blog.apollodata.com/apollo-client-1-0-is-coming-23b74b13fbbb#.1dgnl8yjo" target="_blank" rel="noreferrer noopener">1.0 release</a>&nbsp;of some of the core libraries, things are only going to get more exciting.</p>



<p class="wp-block-paragraph">It can sometimes be hard to follow along with all of the happenings in GraphQL in general and Apollo in particular, so I wanted to put together this quick round up of all of the best places to keep up with what we’re working on, get involved in the project, and find out what’s going on in the community. I’ll put them in order of importance.</p>

<p class="wp-block-paragraph">On the Apollo team, we’ve been passionate about realtime data in GraphQL, and subscriptions in particular, for a long time. We&nbsp;<a href="https://dev-blog.apollodata.com/graphql-subscriptions-in-apollo-client-9a2457f015fb#.lg5kcvr7u" target="_blank" rel="noreferrer noopener">released the first version of our GraphQL subscriptions library</a>, which was the start of our exploration, almost 6 months ago in September.</p>



<p class="wp-block-paragraph">While we initially launched this as a feature for Apollo Client, we quickly realized there was a lot of demand for this across the community, so we put together&nbsp;<a href="https://dev-blog.apollodata.com/a-proposal-for-graphql-subscriptions-1d89b1934c18" target="_blank" rel="noreferrer noopener">a proposal for a subscriptions architecture</a>&nbsp;that could work with any client or server.</p>



<p class="wp-block-paragraph">Since then, we’ve been hard at work improving the implementation libraries, using GraphQL subscriptions internally and getting feedback from the community.</p>



<h3 class="wp-block-heading" id="9504"><a href="#the-new-releases" aria-hidden="true" class="aal_anchor" id="the-new-releases"><svg aria-hidden="true" class="aal_svg" height="16" version="1.1" viewBox="0 0 16 16" width="16"><path fill-rule="evenodd" d="M4 9h1v1H4c-1.5 0-3-1.69-3-3.5S2.55 3 4 3h4c1.45 0 3 1.69 3 3.5 0 1.41-.91 2.72-2 3.25V8.59c.58-.45 1-1.27 1-2.09C10 5.22 8.98 4 8 4H4c-.98 0-2 1.22-2 2.5S3 9 4 9zm9-3h-1v1h1c1 0 2 1.22 2 2.5S13.98 12 13 12H9c-.98 0-2-1.22-2-2.5 0-.83.42-1.64 1-2.09V6.25c-1.09.53-2 1.84-2 3.25C6 11.31 7.55 13 9 13h4c1.45 0 3-1.69 3-3.5S14.5 6 13 6z"></path></svg></a>The new releases</h3>



<p class="wp-block-paragraph">In this post I want to talk about the latest releases:</p>



<ul class="wp-block-list"><li><a href="https://github.com/apollographql/graphql-subscriptions" target="_blank" rel="noreferrer noopener">graphql-subscriptions</a>&nbsp;0.3.0</li><li><a href="https://github.com/apollographql/subscriptions-transport-ws" target="_blank" rel="noreferrer noopener">subscriptions-transport-ws</a>&nbsp;0.5.0</li></ul>



<p class="wp-block-paragraph">These releases included lots of merged PRs and issues fixed from community members who use GraphQL subscriptions in production. We put most of the effort into areas where we had received a lot of feedback from the community:</p>



<ul class="wp-block-list"><li>Improvements for authorization flows</li><li>More lifecycle hooks for the client, giving more control and expression with the connection</li><li>Improved websockets implementation</li><li>Integration with the MQTT protocol in addition to Redis</li></ul>



<p class="wp-block-paragraph">The goal was to make a flexible implementation while keeping the app-specific code easier. On top of that, we wanted to create smaller and more modular package by splitting the subscriptions client and subscriptions server into separate bundles.</p>



<h2 class="wp-block-heading" id="696d"><a href="#client-and-server-lifecycle-events" aria-hidden="true" class="aal_anchor" id="client-and-server-lifecycle-events"><svg aria-hidden="true" class="aal_svg" height="16" version="1.1" viewBox="0 0 16 16" width="16"><path fill-rule="evenodd" d="M4 9h1v1H4c-1.5 0-3-1.69-3-3.5S2.55 3 4 3h4c1.45 0 3 1.69 3 3.5 0 1.41-.91 2.72-2 3.25V8.59c.58-.45 1-1.27 1-2.09C10 5.22 8.98 4 8 4H4c-.98 0-2 1.22-2 2.5S3 9 4 9zm9-3h-1v1h1c1 0 2 1.22 2 2.5S13.98 12 13 12H9c-.98 0-2-1.22-2-2.5 0-.83.42-1.64 1-2.09V6.25c-1.09.53-2 1.84-2 3.25C6 11.31 7.55 13 9 13h4c1.45 0 3-1.69 3-3.5S14.5 6 13 6z"></path></svg></a>Client and server lifecycle events</h2>



<p class="wp-block-paragraph">One of the features most requested by the community was more lifecycle events to track both the state of a subscription and the state of the connection overall. Many of the issues we closed in the last few weeks were related to this missing feature — and now it’s finally here.</p>



<p class="wp-block-paragraph">With the new version of&nbsp;<a href="https://github.com/apollographql/subscriptions-transport-ws" target="_blank" rel="noreferrer noopener">subscriptions-transport-ws</a>&nbsp;you can subscribe for client lifecycle events:&nbsp;<em>connect</em>,&nbsp;<em>disconnect</em>, and&nbsp;<em>reconnect</em>.</p>



<p class="wp-block-paragraph">This gives client developers the ability to respond to those network changes. For example, you can let the user know the app is offline, clear state after logout, disconnect the websocket, or initiate a retry after the connection has reconnected.</p>



<p class="wp-block-paragraph">The new version also adds server lifecycle events:&nbsp;<em>connect</em>,&nbsp;<em>disconnect</em>,&nbsp;<em>subscribe</em>, and&nbsp;<em>unsubscribe</em>.</p>



<p class="wp-block-paragraph">This gives the server developer easier control over authentication logic and the ability to clean up state on the client if the server decides to terminate the connection.</p>

<p class="wp-block-paragraph">In addition to independent life cycle events, in the new version of&nbsp;<a href="https://github.com/apollographql/subscriptions-transport-ws" target="_blank" rel="noreferrer noopener">subscriptions-transport-ws</a>, we added a new type of WebSocket message, called&nbsp;<code class="" data-line="">INIT</code>&nbsp;, which gives developers the ability to pass custom arguments from the client to the server. You can think of this as a way to pass information would have been a header in HTTP.</p>



<p class="wp-block-paragraph">Using this new type of message, you can create an authorized WebSocket by passing your authorization data in the initial request and writing code that accepts or rejects the connection before accepting subscriptions from the client using the&nbsp;<code class="" data-line="">onConnect</code>&nbsp;callback.</p>



<p class="wp-block-paragraph">The following example creates a GraphQL subscriptions client and server, using the new initialization feature and lifecycle events:</p>

<p class="wp-block-paragraph">We also did some code refactor and made the API more flexible. For example, you can now use a Promise for lifecycle events, setupFunctions, setting up the pub/sub engine, and more.</p>



<p class="wp-block-paragraph">Also, there is now a&nbsp;<code class="" data-line="">addGraphQLSubscriptions</code>&nbsp;method in the client side bundle of&nbsp;<a href="https://github.com/apollographql/subscriptions-transport-ws" target="_blank" rel="noreferrer noopener">subscriptions-transport-ws</a>&nbsp;so that developers using Apollo Client no longer need to write this code every time. This method allows you to extend your Apollo network interface to execute GraphQL subscriptions over the WebSocket transport, while using the regular network interface for queries and mutations.</p>



<p class="wp-block-paragraph">We updated our implementation to use the&nbsp;<a href="https://www.npmjs.com/package/ws" target="_blank" rel="noreferrer noopener">ws</a>&nbsp;package for the server side websocket implementation. This means you can also use the client if your subscriptions client is in a server-side NodeJS environment (in browser environment, it’s better to use the native implementation of your browser).</p>



<p class="wp-block-paragraph">The new&nbsp;<code class="" data-line="">ws</code>&nbsp;dependency is much&nbsp;<a href="http://websockets.github.io/ws/benchmarks.html" target="_blank" rel="noreferrer noopener">faster</a>&nbsp;than our previous websocket library. It’s also smaller library and adds less overhead over the websocket standard, which means it’s easier to abstract out and change the implementation if you need to.</p>

<p class="wp-block-paragraph"><a href="https://github.com/apollostack/graphql-subscriptions" target="_blank" rel="noreferrer noopener">graphql-subscriptions</a>&nbsp;package exports a default in-process pub/sub implementation, but for the best result in production it’s better to use an external pub/sub product, such as Redis or an MQTT service.</p>



<p class="wp-block-paragraph">We worked with&nbsp;<a href="https://medium.com/u/c544f341ba49?source=post_page-----f11be19e6569----------------------" target="_blank" rel="noreferrer noopener">David Yahalomi</a>&nbsp;to create the&nbsp;<a href="https://github.com/davidyaha/graphql-redis-subscriptions" target="_blank" rel="noreferrer noopener">graphql-redis-subscriptions</a>&nbsp;and&nbsp;<a href="https://github.com/davidyaha/graphql-mqtt-subscriptions" target="_blank" rel="noreferrer noopener">graphql-mqtt-subscriptions</a>&nbsp;packages, which can be easily dropped in as a replacement for the default PubSub object without making any changes to the rest of your code. Using an external pub/sub system gives you more publication features — such as persistence, caching, delivery guarantees and other optimizations.</p>

<p class="wp-block-paragraph">The&nbsp;<a href="https://github.com/apollostack/apollo-ios" target="_blank" rel="noreferrer noopener">Apollo iOS Client</a>&nbsp;is the best way to work with a GraphQL API from a native iOS app. Developers using the client will benefit from two major features:</p>



<ul class="wp-block-list"><li><strong>Type generation based on GraphQL queries and mutations</strong></li><li><strong>Normalized cache &amp; automatic UI updates</strong></li></ul>



<h3 class="wp-block-heading" id="41bb"><a href="#type-generation" aria-hidden="true" class="aal_anchor" id="type-generation"><svg aria-hidden="true" class="aal_svg" height="16" version="1.1" viewBox="0 0 16 16" width="16"><path fill-rule="evenodd" d="M4 9h1v1H4c-1.5 0-3-1.69-3-3.5S2.55 3 4 3h4c1.45 0 3 1.69 3 3.5 0 1.41-.91 2.72-2 3.25V8.59c.58-.45 1-1.27 1-2.09C10 5.22 8.98 4 8 4H4c-.98 0-2 1.22-2 2.5S3 9 4 9zm9-3h-1v1h1c1 0 2 1.22 2 2.5S13.98 12 13 12H9c-.98 0-2-1.22-2-2.5 0-.83.42-1.64 1-2.09V6.25c-1.09.53-2 1.84-2 3.25C6 11.31 7.55 13 9 13h4c1.45 0 3-1.69 3-3.5S14.5 6 13 6z"></path></svg></a>Type Generation</h3>



<p class="wp-block-paragraph">The first and presumably most important feature of the Apollo iOS client is the&nbsp;<a href="https://dev-blog.apollodata.com/mapping-graphql-types-to-swift-aa85e5693db4#.tjm7h9e8q" target="_blank" rel="noreferrer noopener">generation of native Swift types</a>&nbsp;that reflect the data requirements of your specific application. The types are generated based on all the queries and mutations that are specified within the app’s Xcode project.</p>



<p class="wp-block-paragraph">This approach leverages Swift’s static type system and, unlike most other data fetching approaches, provides&nbsp;<em>compile-time safety&nbsp;</em>for the developer in terms of what data they can expect from the backend. In Swift, this means that developers can get rid of all the&nbsp;<em>optional</em>&nbsp;properties they’d have to use when parsing the untyped JSON into their model objects, thus providing extra safety while retaining flexibility when it comes to changing data requirements.</p>



<h3 class="wp-block-heading" id="dc5f"><a href="#normalized-caching-automatic-ui-updates" aria-hidden="true" class="aal_anchor" id="normalized-caching-automatic-ui-updates"><svg aria-hidden="true" class="aal_svg" height="16" version="1.1" viewBox="0 0 16 16" width="16"><path fill-rule="evenodd" d="M4 9h1v1H4c-1.5 0-3-1.69-3-3.5S2.55 3 4 3h4c1.45 0 3 1.69 3 3.5 0 1.41-.91 2.72-2 3.25V8.59c.58-.45 1-1.27 1-2.09C10 5.22 8.98 4 8 4H4c-.98 0-2 1.22-2 2.5S3 9 4 9zm9-3h-1v1h1c1 0 2 1.22 2 2.5S13.98 12 13 12H9c-.98 0-2-1.22-2-2.5 0-.83.42-1.64 1-2.09V6.25c-1.09.53-2 1.84-2 3.25C6 11.31 7.55 13 9 13h4c1.45 0 3-1.69 3-3.5S14.5 6 13 6z"></path></svg></a>Normalized Caching &amp; Automatic UI updates</h3>



<p class="wp-block-paragraph">The second major feature of the Apollo iOS client is a&nbsp;<a href="http://dev.apollodata.com/ios/watching-queries.html" target="_blank" rel="noreferrer noopener">normalized cache</a>&nbsp;that allows for automatic UI updates. The responses that the client receives from the server are flattened and put into the client-side store. Similar to the Apollo client for other platforms, queries are&nbsp;<a href="http://dev.apollodata.com/ios/watching-queries.html" target="_blank" rel="noreferrer noopener"><em>watched</em></a>&nbsp;in a reactive way so that an update function automatically gets executed whenever data associated with a watched query changes in the store — no matter where that change came from!</p>

<p class="wp-block-paragraph">At&nbsp;<a href="https://www.graph.cool/" target="_blank" rel="noreferrer noopener">Graphcool</a>, we strongly believe that&nbsp;<strong>GraphQL is the API design paradigm of the future</strong>! Despite its young age, it already created an incredible impact on the way how web developers write their applications and interface with backends.</p>



<blockquote class="wp-block-quote is-layout-flow wp-block-quote-is-layout-flow"><p><em>“We were frustrated with the differences between the data we wanted to use in our apps and the server queries they required. We don’t think of data in terms of resource URLs, secondary keys, or join tables; we think about it in terms of a graph of objects and the models we ultimately use in our apps like NSObjects or JSON.” —&nbsp;</em><a href="https://twitter.com/leeb" target="_blank" rel="noreferrer noopener"><em>Lee Byron</em></a><em>&nbsp;(Co-Inventor of GraphQL, Facebook)</em></p></blockquote>



<p class="wp-block-paragraph">Though GraphQL has been widely adopted in the web development community so far, Facebook initially developed it to deal with networking issues they primarily saw on&nbsp;<em>mobile devices</em>&nbsp;— with the&nbsp;<a href="http://graphql.org/blog/graphql-a-query-language/#why-graphql" target="_blank" rel="noreferrer noopener">goal of making the data transfer as efficient as possible</a>&nbsp;while still enabling developers to iterate quickly. This is why we think that there is an&nbsp;<strong>enormous potential for GraphQL in the native mobile development space</strong>! We’re very excited to see more mobile developers using GraphQL, and want to build an ecosystem that makes it as easy as possible for every native developer to integrate GraphQL in their applications.</p>


How to use GraphQL in your iOS app


<p class="wp-block-paragraph">As&nbsp;<a href="https://medium.com/u/db65a320cccc?source=post_page-----39dd139c70ee----------------------" target="_blank" rel="noreferrer noopener">Thea</a>&nbsp;wrote in her&nbsp;<a href="https://medium.com/p/save-the-date-apollo-contributor-week-eef66d09f0e6" target="_blank" rel="noreferrer noopener">announcement blog post</a>&nbsp;last week, the idea for contributor week came to us when we were having our own hack week back in November.

Apollo Contributor Week Starts Today!


<p class="wp-block-paragraph">Late last year, the Apollo team took a week do some collaborative hacking on projects ideas that had been floating around our heads but hadn’t made it into planned sprints. Not only did this end up being really fun, it also yielded some awesome additions to the open source project, including these&nbsp;<a href="https://dev-blog.apollodata.com/apollo-client-developer-tools-ff89181ebcf" target="_blank" rel="noreferrer noopener">Chrome devtools</a>&nbsp;for Apollo Client.</p>



<p class="wp-block-paragraph">Almost immediately afterwards, we had the idea of organizing a hack week for the wider community of Apollo contributors and people looking for a fun opportunity to get involved in open source projects.</p>



<p class="wp-block-paragraph">So 🎉 we’re excited to announce&nbsp;<strong>Apollo Contributor Week</strong>&nbsp;— an online hack week for anyone looking to make contributions to Apollo and related projects, with the core maintainers on deck throughout the week to provide help, design feedback, quick PR reviews, and emotional support. Leading up to Contributor Week, we’ll also be shoring up our projects’ resources and tools to make for an awesome contributing experience.</p>

<p class="wp-block-paragraph">We welcome anyone who is interested in Apollo and GraphQL to join in, including new, existing and past contributors. This is a great chance to help make Apollo an even better tool for your needs, and leave your mark on a&nbsp;<a href="https://dev-blog.apollodata.com/get-involved-in-open-source-today-7c4708cf2a33#.nmf1098ua" target="_blank" rel="noreferrer noopener">rapidly growing open source project</a>. Contributions can span everything from adding tests and updating documentation to significant PRs.</p>



<p class="wp-block-paragraph">We’d love to see contributors from the other open source communities as well, especially if you have ideas on how to better integrate Apollo with your project (and vice versa).</p>



<p class="wp-block-paragraph">For those who are new to our codebase, not all contributions need to come in the form of code! We’ll also be around to help you improve documentation, write that blog post about GraphQL you’ve had on the back burner, or hone a talk you’ve been wanting to give at your local meetup.</p>

Save the Date: Apollo Contributor Week


<p class="wp-block-paragraph">A little over a year ago, we at Meteor Development Group were looking for a way to build the data layer of the future. GraphQL ended up grabbing our attention mainly because it offered a solution to the problem we were trying to solve at the time: how to let clients use just one intuitive query language to query many different backends — Postgres, MySQL, MongoDB, etc. Completely flouting the principle of “not-invented-here”, we decided to see if we could use GraphQL instead of building our own solution in-house.</p>



<p class="wp-block-paragraph">GraphQL checked all the boxes, except for one: there was no easy-to-use client library. There was Relay, but Relay had a notoriously steep learning curve, only worked with React, and didn’t integrate with anything else, not even React-Router. We tried to bend Relay to our will and make it easier and more flexible to use, but quickly realized that it was an almost impossible task because of how tightly coupled Relay was.</p>

<p class="wp-block-paragraph">We were convinced that for GraphQL to be widely adopted, it had to integrate with other popular tools in the Javascript ecosystem, and we believed that the best way to achieve that goal was to involve the open-source community from the start. In short: we needed to build the GraphQL client “for the community, by the community”.</p>



<p class="wp-block-paragraph">At Apollo we strongly believe in the power of open source, but as many of you know, building open source software can be both a source of joy as well as frustration. In this blog post I want to share a few lessons that we’ve learned, in the hope that this will encourage and enable more people to start successful open source projects, because:</p>



<p class="wp-block-paragraph">Every time an open source project succeeds, we all win!</p>

Getting off the ground</h2>



<p class="wp-block-paragraph">The biggest hurdle for every open-source project is to get the first user and the first contributor. It’s usually only when projects become really successful that contributions start pouring in. Unfortunately, there’s no easy shortcut to getting there; you have to make the first step and build something to get the project off the ground.</p>



<p class="wp-block-paragraph">However, if you’re working on something exciting, you can almost always find someone who has the same problem and who’d be happy to start contributing if you take the lead (a friend, a coworker, a lost soul somewhere on a forum)!</p>



<p class="wp-block-paragraph">That’s exactly how things worked out with Apollo Client:&nbsp;<a href="https://medium.com/u/803918030a60?source=post_page-----7c4708cf2a33----------------------" target="_blank" rel="noreferrer noopener">Sashko Stubailo</a>&nbsp;started writing code and quickly found&nbsp;<a href="https://medium.com/u/fd3d3dea3cd3?source=post_page-----7c4708cf2a33----------------------" target="_blank" rel="noreferrer noopener">James Baxley III</a>&nbsp;as our first contributor and production user.

Getting the word out</h3>



<p class="wp-block-paragraph">Successful open source projects — those that help the greatest number of people — are just as much about getting the word out there as they are about quality code. For a project to succeed, it needs to have both. Every once in a while a project comes along that’s so great that word gets around without the authors lifting a finger. That generally only happens to one project out of a thousand, so you’ll have to get the ball rolling yourself.</p>



<p class="wp-block-paragraph">I really can’t emphasize enough how important it is to start getting the word out there so new users and contributors can find your project. An open source project stays alive only as long as it has users who are also able to contribute to it. There are probably hundreds of amazing open source projects that disappear because no one found out about how great they are.</p>



<hr class="wp-block-separator"/>



<p class="wp-block-paragraph">For Apollo Client, this very publication is the main way we reach new users and contributors. We simply set ourselves a goal of writing two posts per week, even if there wasn’t anything specific to write about. If there were no news to share about the project itself, we simply wrote up some of the insights that we had while working on the project, like&nbsp;<a href="https://dev-blog.apollodata.com/understanding-pagination-rest-graphql-and-relay-b10f835549e7" target="_blank" rel="noreferrer noopener">how to do pagination</a>&nbsp;or a&nbsp;<a href="https://dev-blog.apollodata.com/graphql-vs-falcor-4f1e9cbf7504" target="_blank" rel="noreferrer noopener">comparison between GraphQL and Falcor</a>.</p>



<p class="wp-block-paragraph">You don’t need to be famous to start a blog on Medium, all you have to do is sign up and start writing. Literally anyone can start a blog, or post on Reddit, and submit stuff to Hacker News. Do it now!</p>



<p class="wp-block-paragraph">If you’re thinking about waiting on that blog until the code looks nicer, until the documentation is better etc., here’s a secret tip:&nbsp;<strong>don’t</strong>! Your project will never be perfect. In fact, if you’re like me, you’ll never think that your project is good enough. Fortunately, it doesn’t have to be. The sooner you talk about it the better: nobody expects a project or idea to be perfect in the early stages, but if you wait until you think it’s perfect, it will be difficult to make use of helpful criticism.</p>



<p class="wp-block-paragraph">There’s another upside to writing and talking about your project early: We’re usually not the best at judging the merit of our own projects. If you put your idea out there early you can get feedback much sooner, and focus on building what’s really valuable. You might even find some early contributors that way.</p>

Making it easy to understand</h3>



<p class="wp-block-paragraph">As I mentioned earlier, an open source project lives and dies by its contributors. Apart from getting the word out early and often, a critical part of acquiring new contributors is to lower the barrier of entry and make it as easy as possible to contribute. If you can explain your project’s purpose to someone in a few sentences and get an example running for them in a few minutes, the chances are much higher that they’ll be able to understand enough about your project to be able to contribute to it.</p>



<p class="wp-block-paragraph">Here are a few ways that we used to make Apollo Client easier to understand:</p>



<ul class="wp-block-list"><li>We have a&nbsp;<a href="https://github.com/apollostack/GitHunt-React" target="_blank" rel="noreferrer noopener">demo</a>&nbsp;that anyone can run, or copy-paste from</li><li>We have&nbsp;<a href="http://dev.apollodata.com/" target="_blank" rel="noreferrer noopener">extensive documentation</a></li><li>We wrote blog posts about many of the&nbsp;<a href="https://medium.com/p/the-concepts-of-graphql-bc68bd819be3" target="_blank" rel="noreferrer noopener">concepts</a>&nbsp;and&nbsp;<a href="https://medium.com/p/apollo-client-0-5-f1eb3f122ace" target="_blank" rel="noreferrer noopener">features</a></li><li>We made Apollo integrate with&nbsp;<a href="http://redux.js.org/" target="_blank" rel="noreferrer noopener">Redux</a>&nbsp;because&nbsp;<a href="https://egghead.io/courses/getting-started-with-redux" target="_blank" rel="noreferrer noopener">everyone gets Redux</a>.</li></ul>



<p class="wp-block-paragraph">There’s still room to do a lot more, which is why we’re constantly working on improving our documentation and creating better examples.</p>



<h3 class="wp-block-heading" id="be49"><a href="#4-empowering-contributors" aria-hidden="true" class="aal_anchor" id="4-empowering-contributors"><svg aria-hidden="true" class="aal_svg" height="16" version="1.1" viewBox="0 0 16 16" width="16"><path fill-rule="evenodd" d="M4 9h1v1H4c-1.5 0-3-1.69-3-3.5S2.55 3 4 3h4c1.45 0 3 1.69 3 3.5 0 1.41-.91 2.72-2 3.25V8.59c.58-.45 1-1.27 1-2.09C10 5.22 8.98 4 8 4H4c-.98 0-2 1.22-2 2.5S3 9 4 9zm9-3h-1v1h1c1 0 2 1.22 2 2.5S13.98 12 13 12H9c-.98 0-2-1.22-2-2.5 0-.83.42-1.64 1-2.09V6.25c-1.09.53-2 1.84-2 3.25C6 11.31 7.55 13 9 13h4c1.45 0 3-1.69 3-3.5S14.5 6 13 6z"></path></svg></a>4. Empowering contributors</h3>



<p class="wp-block-paragraph">Maintaining an open source project requires constant effort. Responding to issues and fixing bugs can be a lot of work, especially if your project becomes successful. It’s much better if that responsibility can be shared by more people. The best way to do that is to empower contributors and make sure they get the appreciation they deserve. Your goal should be to enable every contributor to become a potential maintainer.</p>



<p class="wp-block-paragraph">Empowering contributors is one of the best things you can do for your project, because it will not only greatly increase the amount of work that can go into the project, it will also make the project much more likely to survive if one of the core contributors/maintainers pulls out.</p>



<p class="wp-block-paragraph">Here are some of the things you can do to empower contributors:</p>



<ul class="wp-block-list"><li>Respond to issues and pull requests as soon as possible (but don’t overwork yourself)</li><li>Give people an opportunity to fix the bugs they find. Make sure to give them all the instructions they need to succeed.</li><li>Work with contributors to get their PRs merged quickly. As a new contributor, it’s very motivating to see your PR getting attention from the maintainers.</li><li>Make your project easier to contribute to by enforcing good coding style and good tests.</li><li>Let contributors make major contributions and listen to them when making major design decisions.</li></ul>



<p class="wp-block-paragraph">On Apollo we’ve been incredibly lucky with the contributors we’ve had. Each of them contributed their own expertise to our project, and without them we wouldn’t be where we are today.

Thanks a lot guys, you are awesome!!</p>



<p class="wp-block-paragraph">Of course that’s only the tip of the iceberg, and we have many more great contributors that I wish I had the space to write about here! Each and every contribution makes a difference, no matter how small. If you’re one of the contributors, thank you very much for your efforts! I hope I’ll get a chance to write about your help in a future post!</p>

<p class="wp-block-paragraph">While getting off the ground and getting the word out are things that should require less and less of your time as your project matures, making your project easy to understand and empowering contributors are things that require constant attention. These are also the things we still feel like we need to improve on the most:</p>



<ul class="wp-block-list"><li>We still need to make the project easier to contribute to by simplifying the code and writing better documentation.</li><li>We still need to get better at empowering and connecting with contributors.</li><li>We still need to work harder to get PRs merged and issues resolved quickly.</li></ul>



<p class="wp-block-paragraph">Despite all the things that still need to improve, I’m extremely optimistic and constantly amazed by how far we have come: In less than 10 months Apollo Client went from zero to over 1600 stars on GitHub. It now has 60 contributors and over 2300 commits in 86 releases, and with over 10,000 downloads per week it is the most popular GraphQL client on npm!</p>



<p class="wp-block-paragraph">None of this would have been possible without our amazing&nbsp;<a href="https://github.com/apollostack/apollo-client/graphs/contributors" target="_blank" rel="noreferrer noopener">community of open-source contributors</a>, so a big Thank You to all of you!</p>

<p class="wp-block-paragraph">NewSpring Church is a Southern Baptist megachurch headquartered in Anderson, South Carolina. In addition to its main location, which receives an average of 32,000 visitors per week, NewSpring has more than a dozen locations in cities and towns throughout the state.</p>



<div class="wp-block-image"><figure class="alignleft size-large"><img loading="lazy" decoding="async" width="300" height="77" src="https://apollographql.wpengine.com/wp-content/uploads/2020/03/1_QAWOno5bP8XMRCSmp1BKag.png" alt="" class="wp-image-479"/></figure></div>



<p class="wp-block-paragraph">NewSpring is one of the fastest-growing churches in the country. The church’s development team has had to build and maintain a variety of websites and applications for the various locations in order to adequately serve employees and congregants. The church also operates several institutions, including a leadership college and a youth ministry, each with its own technical needs.</p>



<p class="wp-block-paragraph">Due to the massive increases in growth and attendance year after year, NewSpring’s technical team has cobbled together a number of internal and third-party solutions in order to keep everything running. “I came into an organization that had grown very fast, and needed very quickly to sign up for a number of different services to be able to sustain itself,” said James Baxley, NewSpring’s director of web systems development. “It was a very distributed data system, with a lot of stuff in the wrong place and not really in sync.” The team wanted to unify the various solutions put into place so that users could have one central hub of activity without signing into a dozen different portals.</p>



<h2 class="wp-block-heading" id="3306"><a href="#migrating-to-graphql" aria-hidden="true" class="aal_anchor" id="migrating-to-graphql"><svg aria-hidden="true" class="aal_svg" height="16" version="1.1" viewBox="0 0 16 16" width="16"><path fill-rule="evenodd" d="M4 9h1v1H4c-1.5 0-3-1.69-3-3.5S2.55 3 4 3h4c1.45 0 3 1.69 3 3.5 0 1.41-.91 2.72-2 3.25V8.59c.58-.45 1-1.27 1-2.09C10 5.22 8.98 4 8 4H4c-.98 0-2 1.22-2 2.5S3 9 4 9zm9-3h-1v1h1c1 0 2 1.22 2 2.5S13.98 12 13 12H9c-.98 0-2-1.22-2-2.5 0-.83.42-1.64 1-2.09V6.25c-1.09.53-2 1.84-2 3.25C6 11.31 7.55 13 9 13h4c1.45 0 3-1.69 3-3.5S14.5 6 13 6z"></path></svg></a>Migrating to GraphQL</h2>



<p class="wp-block-paragraph">With this objective in mind, Baxley and the NewSpring team began to seriously look into adding&nbsp;<a href="https://graphql.com/" target="_blank" rel="noreferrer noopener">GraphQL</a>&nbsp;into its technical stack. The team already relied on ExpressionEngine, a PHP and MySQL content management system, as well as third-party church management software and a number of REST endpoints. Because the stack was so large, any new solution needed to play nicely with these existing technologies.</p>



<p class="wp-block-paragraph">When deciding whether to use GraphQL, the development team had three main concerns:</p>



<ul class="wp-block-list"><li>First, GraphQL was a very new technology; the specifications had only been officially been announced five or six months previously. The team needed reassurance that GraphQL would have support for the foreseeable future and wasn’t just a flash in the pan.</li><li>Second, even a delay of 100 milliseconds is enough to push users away from a website, so speed would be a paramount concern.</li><li>Third, NewSpring keeps track of a large amount of sensitive data, including financial information and personal conversations. Protecting user data was a critical need for the new system.</li></ul>



<p class="wp-block-paragraph">“Whatever choice we made in how to handle our data had to provide the security and reliability to keep the lights on and set us up for future success,” said Baxley. “GraphQL is that choice.”</p>

<p class="wp-block-paragraph">To supplement the adoption of GraphQL, NewSpring used&nbsp;<a href="http://apollodata.com/optics" target="_blank" rel="noreferrer noopener">Apollo Optics</a>&nbsp;to provide system analytics. Optics let the NewSpring team target queries that were unnecessarily slow or causing problems with caching, allowing them to make numerous improvements and optimizations. Optics makes it simple for the team to find any significant spike in response time, offering a closer look in order to identify where the issue is coming from and determine how much of the problem is due to the application’s caching mechanisms.</p>

<p class="wp-block-paragraph">By using&nbsp;<a href="http://apollodata.com/optics" target="_blank" rel="noreferrer noopener">Apollo Optics</a>&nbsp;to sort by the length of time taken for a query, the NewSpring team can easily identify the weak spots in their application. For example, the development team noticed that looking up a person was one of the most time-consuming tasks because the application needed to move from a user account to a record for a person, which could potentially involve merge operations in SQL. Initially, developers assumed that one person would only have one user account and only require a simple check, but this proved not to be the case in production. Optics allowed NewSpring to troubleshoot the issue and tag this pain point for optimization.</p>



<p class="wp-block-paragraph">“Optics was the fastest way for us to take GraphQL projects from prototype to production” — James Baxley</p>



<p class="wp-block-paragraph">The operations team also uses Optics to analyze queries during major events, such as Sunday or holiday services. The application lets them view the different usage patterns in the form of GraphQL queries to give them an idea of how successful their efforts have been. By helping to identify inefficiencies, points of overuse and potential areas of improvement, Optics has become a key part of the NewSpring team’s daily toolbox. “Optics was the fastest way for us to take GraphQL projects from prototype to production,” said Baxley.</p>

<p class="wp-block-paragraph">After working with GraphQL and Optics, the NewSpring team is excited about the chance to use what they’ve built and help other churches unify around a common schema. In addition, the team wants to implement some key system features that have been sorely missing so far.</p>



<p class="wp-block-paragraph">First, Apollo is able to support subscriptions as they are implemented in GraphQL. The NewSpring team is hoping to use the subscriptions feature to build a chat platform using GraphQL, giving end users more functionality and putting a cutting-edge technology into production.</p>



<p class="wp-block-paragraph">Second, NewSpring’s GraphQL server is currently written in JavaScript, but the team has developed an application in conjunction with other churches written in C#. Moving forward, one of the biggest tasks will be to transition the NewSpring GraphQL server to C#, so that they can promote GraphQL amongst the church tech community.</p>

<p class="wp-block-paragraph"><em>I guess before we get too deep into some of this technical stuff, for people that are listening that maybe haven’t used Apollo. What is the elevator pitch for Apollo? When you guys built this thing, what was the main problem that you were trying to solve? What’s the main draw and idea behind it?</em><br><br><strong>Sashko:&nbsp;</strong>At the end of the day it’s very simple. Our goal with Apollo is to make it easy for people to get all the benefits of GraphQL in their apps, regardless of what frontends or backends they are using. The benefits of GraphQL are so great that we don’t have to do very much on top of that. It’s just about enabling people to take advantage of GraphQL in the best way.<br><br>For example, Apollo Client is a caching JavaScript client for GraphQL. React Apollo is a really popular way to use GraphQL data in your React application. The integration there is quite simple because the Apollo client core does most of the work for you. You can come in, you can say, “Okay, I don’t like the way it does Optimistic UI, and I’m going to replace that part.” Then you have essentially your own GraphQL client that does what you need. Or you can integrate with Polymer or Angular or Ember, or any other framework that you like. The idea is it implements the core stuff that’s really useful and then you can customize from there to get what you need.<br><br>On the server it’s a lot more JavaScript focused. The server-side tools we’re building are just some layers around the JavaScript reference implementation, but just make it easier to describe your schema, or set up a server, things like that.<br><br><strong>Tom:</strong>&nbsp;Our specialty I suppose is primarily JavaScript, given that we’re a dev tools company that build a JavaScript framework, but it’s not exclusively that. For instance we now have a client for iOS that we’ve been building, just because there wasn’t really a complete iOS client out there for GraphQL that people were commonly using, so we saw a need for that and so invested a bunch of time in getting that going.<br><br>That’s really the focus of Apollo, is just making it easier for people to get going, as Sashko said, especially in the open source world. It’s about making your experience better.</p>

<p class="wp-block-paragraph"><em>Could I use Redux or any one of these other Flux frameworks with Apollo? Is there any reason why I would want to do something like this?</em><br><br><strong>Sashko:</strong>&nbsp;It’s even better than that. Apollo client is built on top of Redux. Basically everyone’s who’s building React apps is using Redux to manage their data. That was one of the things we were missing when we started, is the way to integrate that with GraphQL. That’s actually where Apollo Client started from, the idea that using Redux with GraphQL should be really powerful and intuitive.<br><br>The way Apollo client works is you can use it without thinking about Redux, you just initialize the client and it just works, but you can also attach it to an existing Redux store. You get the benefit of being able to look at the Redux dev tools. You can see exactly where your query results are coming in, and how they’re being recorded in the store alongside your client data.<br><br>It’s really natural to use your Redux data as input into your query results. It’s actually designed especially for people who like the insight into their app data that Redux gives you, and people that are already using Redux in their app.<br><br><em>That’s so cool. I’m so glad that I asked that question.</em><br><br><strong>Sashko:&nbsp;</strong>We saw a billion questions on the internet that were like, “How do I use Redux for GraphQL?” It’s silly that there wasn’t a first class way to do that, because everyone is using Redux and everyone wants to learn about GraphQL. They should go together, because they’re the two most popular data related things right now, so yeah I’m really fond of that.</p>

<p class="wp-block-paragraph"><em>One other question that I want to ask is, since we’re talking about the Redux and components. In my current job I have to do a lot of server site rendering, and I’m just wondering if I start using Apollo, do I have to do any configuration or it comes out of the box?</em><br><br><strong>Tom:</strong>&nbsp;Yeah, that’s actually something that we have in the React integration of Apollo client. There’s a function in there called renderToStringWithData. It basically just calls React render to string, but before doing that it walks the tree, figures out which queries you need to call, calls them, waits for the data to come back, and then renders the string. So in a sense I guess you don’t have to really do anything beyond write one line of code that calls it. In general, in my experience, you don’t really need to change the way that you wrote your components, it should all just work out of the box. Like any isomorphic thing there can be caveats and stuff, but I haven’t seen any problems with SSR in Apollo client itself.<br><br><strong>Sashko:</strong>&nbsp;One other cool thing I wanted to add to that, because all of the data is stored in Redux, the way that you do server hydration is identical. You just serialize the contents of the Redux store and then put that back in on the client. It also works with some of these other libraries that help manage Redux data. They work out of the box, because it’s just regular Redux stuff.<br><br><strong>Tom:</strong>&nbsp;And some users that generate their HTML on the server outside of Node, for instance some Rails users, have also been able to inject hydrated data, which is really cool.</p>

<p class="wp-block-paragraph"><em>Nader: What are you guys working on now and what do you want to introduce into the project in the near and far future?</em><br><br><strong>Sashko:</strong>&nbsp;I am really excited about this because we only very recently got to the point where we’re really comfortable with the set of features Apollo Client has as a GraphQL client. We have high standards so for us stuff like server-side rendering was included as a base level feature that we wanted to have. The next step we’re working on is sugar on top you might say.<br><br>The first thing is working on performance, so benchmarking in our own apps, what can we do to squeeze out a little bit of extra performance here and there, or to find out if it’s even a problem. I think it’s particularly something that people might care about on really slow devices like mobile. React Native might be running on some really old device and in that case, we’re not really sure yet exactly what the characteristics will be.<br><br>The other thing is just things we’ve never really seen done before. One thing in particular I’m really excited about is having something like an Apollo dev tools. There’s the Redux dev tools for example which gives you some insight into your redux store. I think it’s one of the most exciting parts about using redux, is that you can see exactly what’s going on in your app.<br><br>Because our redux store and our actions are much more meaningful, we know exactly what action it’s going to be firing, what they mean. We can build an experience on top of that, that will show you exactly what data from your server is cached, let you run GraphQL queries inside Chrome against your client store, tell you what queries are attached to which UI component and when they’re re-running and why and how often UI is working. We think we can build some really great tooling that will help people understand even more about what their app is doing at any given time.</p>



<p class="wp-block-paragraph">(Editor note: The dev tools we were talking about were built as part of our company hack week and released a week ago!)<a href="https://dev-blog.apollodata.com/apollo-client-developer-tools-ff89181ebcf" target="_blank" rel="noreferrer noopener">Apollo Client Developer ToolsGraphQL debugging tools for Apollo Client in the Chrome developer consoledev-blog.apollodata.com</a></p>



<p class="wp-block-paragraph"><strong>Tom:&nbsp;</strong>Yeah. The other thing that I wanted to mention that we’re looking at in the larger context is investigating if there are ways to make it even easier to get started, especially on the server. It would be great to have, at least for that first exposure to GraphQL, a way to just get something up and running really quickly, start building your frontend, and start playing around with what your schema might look like. We’re big proponents of what we call&nbsp;<a href="https://dev-blog.apollodata.com/navigating-your-transition-to-graphql-28a4dfa3acfb#.4t5ahyr5u" target="_blank" rel="noreferrer noopener">GraphQL first</a>&nbsp;application development, which is basically where you start with your schema.</p>



<p class="wp-block-paragraph">Once you’ve done that you can start building your frontend and backend in parallel, so figuring out a way to really make it really easy to stand up a schema and start playing with it, and have a server that serves it, but without necessarily having to properly implement the server in a production way could be really fruitful, so something we’re investigating at the moment. I think it would be really cool.</p>

<p class="wp-block-paragraph"><em>For anyone listening that might not be familiar enough with GraphQL in general, is this something they can pick up and attach to the their existing Rest API database implementation, or does their backend need to be rewritten to handle this type of technology.</em></p>



<p class="wp-block-paragraph"><strong>Tom:</strong>&nbsp;GraphQL is definitely something that you can add on, both on the frontend and the backend. For instance in the Node world, if you’re using Express you can just add a new route, typically called /graphql, which will serve GraphQL queries. You can continue to serve all your old endpoints, and you may continue to do that indefinitely. There’s no reason you can’t use Rest and GraphQL side by side. On the server you have GraphQL resolvers, which are the functions that get called to figure out what the result of a query should be. They can go ahead and call any other function in your backend. Typically they should be pretty thin and they should go straight to your model layer, where all of the logic should live.</p>



<p class="wp-block-paragraph">Typically your REST endpoint handlers and GraphQL resolvers will look pretty similar, and they both just call out to a model somewhere with some arguments. They don’t do a lot of logic.</p>



<p class="wp-block-paragraph">On the front end you can definitely start using GraphQL while continuing to do whatever it is that you were doing before to get data. You could have one part of your site which uses Apollo or Relay to fetch data, and attach it to one sub-tree of your React rendering tree, and the rest of your tree might use data that’s been fetched into Redux via REST or whatever other mechanism you have fetching data.</p>



<p class="wp-block-paragraph">There’s really, absolutely no reason why you shouldn’t do that. In fact that’s what a lot of people do and do it very successfully. Our hope would be that over time all of your app would become GraphQL or Apollo, but of course that going to depend on what makes sense for you and what works best.</p>

<p class="wp-block-paragraph">To help you focus entirely on using Apollo in a frontend application, we’ve included a pre-configured GraphQL backend endpoint which works out of the box with every example app. Your backend can be accessed via GraphiQL or the integrated data browser. All you need to do is to authenticate with Github to get your personal GraphQL endpoint.</p>

<p class="wp-block-paragraph">In my latest job, I worked on a large GraphQL project where we had a lot of fragments. This rapidly became a pain to work with. We had many issues to correctly import those fragments in files scattered around the project. This made most of our fragment resolution not static at all.&nbsp;<code class="" data-line="">&lt;a href=&quot;https://github.com/apollostack/graphql-document-collector&quot; target=&quot;_blank&quot; rel=&quot;noreferrer noopener&quot;&gt;graphql-document-collector&lt;/a&gt;</code>&nbsp;has been created to solve this problem: instead of storing queries and fragments in js files, we can now store them in static graphql files around the project. The collector will gather all documents (fragments, queries, mutations, etc) found in the project and put them in a single file containing all of the project documents with their fragments auto-resolved!</p>



<p class="wp-block-paragraph">This is usually done using a single command:</p>



<pre class="wp-block-preformatted">graphql-document-collector '**/*.graphql' &gt; documents.json</pre>



<p class="wp-block-paragraph">This JSON file contains all of the documents you may want to use, let’s see how I would use that in my project:</p>



<pre class="wp-block-prismatic-blocks"><code class="language-javascript" data-line="">// ...
import {graphql} from &#039;react-apollo&#039;;
const graphqlDocuments = require(&#039;./documents.json&#039;);

// ...

const FeedWithData = graphql(graphqlDocuments[&#039;Feed.graphql&#039;])(Feed);

// ...</code></pre>



<p class="wp-block-paragraph">That’s pretty straightforward; you don’t even need to use the&nbsp;<code class="" data-line="">gql</code>&nbsp;tag. In this case,&nbsp;<code class="" data-line="">Feed.graphql</code>&nbsp;can use fragments located in a file named&nbsp;<code class="" data-line="">fragments/Item.graphql</code>: the collector will handle that for us. The only limitation is that you can&#8217;t have two fragments with the same name in your project.</p>



<h2 class="wp-block-heading" id="be50"><a href="#automatic-type-annotation-generation-for-typescript" aria-hidden="true" class="aal_anchor" id="automatic-type-annotation-generation-for-typescript"><svg aria-hidden="true" class="aal_svg" height="16" version="1.1" viewBox="0 0 16 16" width="16"><path fill-rule="evenodd" d="M4 9h1v1H4c-1.5 0-3-1.69-3-3.5S2.55 3 4 3h4c1.45 0 3 1.69 3 3.5 0 1.41-.91 2.72-2 3.25V8.59c.58-.45 1-1.27 1-2.09C10 5.22 8.98 4 8 4H4c-.98 0-2 1.22-2 2.5S3 9 4 9zm9-3h-1v1h1c1 0 2 1.22 2 2.5S13.98 12 13 12H9c-.98 0-2-1.22-2-2.5 0-.83.42-1.64 1-2.09V6.25c-1.09.53-2 1.84-2 3.25C6 11.31 7.55 13 9 13h4c1.45 0 3-1.69 3-3.5S14.5 6 13 6z"></path></svg></a>Automatic type annotation generation for TypeScript</h2>



<p class="wp-block-paragraph">Another issue we had was in guaranteeing the data we were accessing in our UI was corresponding to the query we just had fetched, even when we changed our queries in our codebase. Alongside our operations and fragments we added type annotations corresponding to the graphql document. Unfortunately, the annotations and the queries stopped matching each other over time. Either we forgot to report a field removal or we just misinterpreted the type from the schema, for instance, making something non-nullable that should be nullable.</p>



<p class="wp-block-paragraph">Since GraphQL is a completely typed language and our queries are now completely static, we can now generate those annotations automatically! In order to do that in a TypeScript project, I added to&nbsp;<code class="" data-line="">&lt;a href=&quot;https://github.com/apollostack/apollo-codegen&quot; target=&quot;_blank&quot; rel=&quot;noreferrer noopener&quot;&gt;apollo-codegen&lt;/a&gt;</code>&nbsp;a generator that converts GraphQL documents and schema to typescript interfaces.</p>



<p class="wp-block-paragraph">Let’s take this simple query with a fragment:</p>



<pre class="wp-block-prismatic-blocks"><code class="language-graphql" data-line="">fragment DescribeHero on Character {
  name
  appearsIn
}

query HeroName($episode: Episode) {
  hero(episode: $episode) {
    ...DescribeHero
  }
}</code></pre>



<p class="wp-block-paragraph">With the following schema:</p>



<pre class="wp-block-prismatic-blocks"><code class="language-graphql" data-line="">enum Episode {
  NEWHOPE
  EMPIRE
  JEDI
}

type Character {
  id: ID!
  name: String!
  friends: [Character]
  appearsIn: [Episode]
}

type Query {
  hero(episode: Episode): Character!
}</code></pre>



<p class="wp-block-paragraph">With those, using <code class="" data-line="">apollo-codegen</code> for TypeScript, we can generate this annotations file:</p>



<pre class="wp-block-prismatic-blocks"><code class="language-typescript" data-line="">//  This file was automatically generated and should not be edited.

// The episodes in the Star Wars trilogy
export type Episode =
  &quot;NEWHOPE&quot; | // Star Wars Episode IV: A New Hope, released in 1977.
  &quot;EMPIRE&quot; | // Star Wars Episode V: The Empire Strikes Back, released in 1980.
  &quot;JEDI&quot;; // Star Wars Episode VI: Return of the Jedi, released in 1983.


export interface HeroNameQueryVariables {
  episode: Episode | null;
}

export interface HeroNameQuery {
  hero: DescribeHeroFragment;
}

export interface DescribeHeroFragment {
  name: string;
  appearsIn: Array&lt; Episode | null &gt;;
}</code></pre>



<p class="wp-block-paragraph">All you have to do is pull your schema with an introspection query from your server:</p>



<pre class="wp-block-preformatted">apollo-codegen download <a href="http://localhost:8080/graphql" target="_blank" rel="noreferrer noopener">http://localhost:8080/graphql</a> \<br>  --output schema.json</pre>



<p class="wp-block-paragraph">Once you have the schema, generate the annotations:</p>



<pre class="wp-block-preformatted">apollo-codegen generate **/*.graphql \<br>  --schema schema.json \<br>  --target ts \<br>  --output schema.ts</pre>



<p class="wp-block-paragraph">You can now import and use those annotations in your codebase to ensure your GraphQL results are used safely. For instance, now, if I try to type this:</p>



<pre class="wp-block-prismatic-blocks"><code class="language-typescript" data-line="">import {
  HeroNameQueryVariables,
  HeroNameQuery,
} from &#039;./schema&#039;;

// ...

const variables: HeroNameQueryVariables = {
  episode: &#039;JARJAR&#039;,
};
// [ts] Type &#039;{ episode: &quot;JARJAR&quot;; }&#039; is not assignable to type &#039;HeroNameQueryVariables&#039;.
//      Types of property &#039;episode&#039; are incompatible.
//      Type &#039;&quot;JARJAR&quot;&#039; is not assignable to type &#039;Episode&#039;.

client.query({
  query: graphqlDocuments[&#039;DescribeHero.graphql&#039;],
  variables,
})
.then(({data}: {data: HeroNameQuery}) =&gt; {
  data.hero.friends.forEach(friend =&gt; console.log(friend.name));
  // [ts] Property &#039;friends&#039; does not exist on type &#039;DescribeHeroFragment&#039;.
});</code></pre>

<p class="wp-block-paragraph">Since we just downloaded a&nbsp;<code class="" data-line="">schema.json</code>, it&#8217;s good to know we can use it to type check our GraphQL documents as well.

(you will need to configure your editor to consider graphql files as javascript files.) You can then write correct queries from the start without having to type them in Graph<em>i</em>QL since ESLint will show you errors directly:</p>



<pre class="wp-block-prismatic-blocks"><code class="language-graphql" data-line="">fragment DescribeHero on Character {
  name
  appearsIn
  isJarJar
  # [eslint] Cannot query field &quot;isJarJar&quot; on type &quot;Character&quot;. (graphql/template-strings)

query HeroName {

  # [eslint] Argument &quot;episode&quot; has invalid value JARJAR.
  #          Expected type &quot;Episode&quot;, found JARJAR. (graphql/template-strings)
    ...DescribeHero
  }

There’s one thing in particular that is starting to emerge as a de-facto best practice in the GraphQL community:</p>



<p class="wp-block-paragraph"><strong>It’s best to write your GraphQL queries as static strings using the GraphQL query language.</strong></p>



<p class="wp-block-paragraph">This means:</p>



<ol class="wp-block-list"><li>It’s best to avoid generating queries dynamically at runtime</li><li>It’s good to use the GraphQL query language directly, rather than a language-specific syntax or query builder</li></ol>



<p class="wp-block-paragraph">You have two approaches: write the query strings inside your code, using something like a&nbsp;<a href="https://github.com/apollostack/graphql-tag" target="_blank" rel="noreferrer noopener">tagged template literal</a>&nbsp;in JavaScript, or alongside your code in .graphql files, which is the preferred approach for&nbsp;<a href="https://github.com/apollostack/apollo-ios" target="_blank" rel="noreferrer noopener">native mobile clients</a>.</p>



<p class="wp-block-paragraph">The most common objection is that if you use strings for queries, you won’t get features like editor integration and code highlighting, but in fact it’s just the opposite: all of the best GraphQL tools and integrations rely on the static query language.</p>

<p class="wp-block-paragraph">Below is an animation taken from the <a rel="noreferrer noopener" href="https://github.com/jimkyndemeyer/js-graphql-intellij-plugin" target="_blank">GitHub page</a> of Jim Kynde Meyer’s GraphQL IntelliJ plugin:</p>

<p class="wp-block-paragraph">As you can see, with this plugin your query strings become much more than just strings — they give you validation errors, autocompletion, highlighting, and more. Because this tool just works with the GraphQL query language, it also works with all popular GraphQL clients, including&nbsp;<a href="http://dev.apollodata.com/" target="_blank" rel="noreferrer noopener">Apollo</a>&nbsp;and&nbsp;<a href="https://facebook.github.io/relay/" target="_blank" rel="noreferrer noopener">Relay</a>.</p>

Code generation for static typing</h2>



<p class="wp-block-paragraph">Internally at Facebook, GraphQL queries are used to generate native code that does the fetch and returns typed results. You can read more about this in our&nbsp;<a href="https://medium.com/apollo-stack/native-code-generation-at-facebook-7d6d0db4f3ee#.hp9jv7pvo" target="_blank" rel="noreferrer noopener">previous post summarizing a talk by Hyo Jeong from Facebook</a>.</p>



<p class="wp-block-paragraph">But it’s not just a Facebook thing anymore; the community is starting to catch up! For example, take&nbsp;<a href="https://medium.com/apollo-stack/bringing-graphql-to-ios-fc46423befa1#.4598i3hcp" target="_blank" rel="noreferrer noopener">Apollo iOS</a>, a code-generation GraphQL client for Swift. This tool has some great features:</p>



<ol class="wp-block-list"><li>Detects all .graphql files in the project</li><li>Validates queries against your schema</li><li>Rebuilds your code when you change the queries</li><li>Gives you typed result objects based on queries and fragments</li></ol>



<p class="wp-block-paragraph">It integrates deeply with the Swift type system, making sure that fields are declared as optional when they are nullable in the GraphQL schema, for example.</p>

<p class="wp-block-paragraph">And that’s just the start — people in the Apollo community are working on&nbsp;<a href="https://github.com/apollostack/apollo-codegen/tree/ts-codegen" target="_blank" rel="noreferrer noopener">TypeScript and Flow code generation</a>&nbsp;as well, so that you can get the same experience in your JS app! Because GraphQL is so structured, you can make sure you get only the data you need, and your tools can check it for you.</p>

Server-side logging</h2>



<p class="wp-block-paragraph">Have you even wondered what GraphQL&nbsp;<a href="http://graphql.org/learn/queries/#operation-name" target="_blank" rel="noreferrer noopener">operation names</a>&nbsp;are for? For example, in the following query:</p>



<pre class="wp-block-preformatted">query HeroNameAndFriends($episode: Episode) {<br>  hero(episode: $episode) {<br>    name<br>    friends {<br>      name<br>    }<br>  }<br>}</pre>



<p class="wp-block-paragraph">The&nbsp;<strong>HeroNameAndFriends</strong>&nbsp;is the operation name of the query. Fragments have names, too. In REST, we had endpoint URLs to track what data was being accessed. Operation names are the equivalent for GraphQL.</p>



<p class="wp-block-paragraph">These can be&nbsp;<em>extremely</em>&nbsp;useful tools to use on the server side to analyze the performance and frequency of your GraphQL queries. Facebook uses them heavily to track changes in their native iOS and Android apps over time, which use their closed-source internal GraphQL clients.</p>



<p class="wp-block-paragraph">Unfortunately, most open-source GraphQL clients available today, including Relay 1 and Lokka, generate dynamic queries on the fly, making the operation name and fragment names no longer meaningful (for example, a common fragment name you’ll see on your server if you’re using Relay 1 is&nbsp;<em>RQL_12</em>or similar).</p>



<p class="wp-block-paragraph">That’s why Apollo Client only uses static queries with no dynamic generation at all, keeping your operation and fragment names intact. Relay 2 is being re-architected to have much more predictable queries as well.</p>

Persisted queries</h2>



<p class="wp-block-paragraph"><em>Note: Since the time of writing,&nbsp;</em><strong><em>we launched persisted queries for Apollo Client</em></strong><em>! Read about it in the post below:</em><a href="https://dev-blog.apollodata.com/persisted-graphql-queries-with-apollo-client-119fd7e6bba5" target="_blank" rel="noreferrer noopener">Persisted GraphQL Queries with Apollo ClientIf you’re a regular at a diner, you know that saying the full name of a dish is a rookie move. If you refer to the…dev-blog.apollodata.com</a></p>



<p class="wp-block-paragraph">In addition to queries being analyzable, trackable, and identifiable, there’s one more important benefit to static queries. It’s a concept Facebook uses heavily and has been calling&nbsp;<strong>persisted queries</strong>.</p>



<p class="wp-block-paragraph">This question has been asked in many ways before:</p>



<blockquote class="wp-block-quote is-layout-flow wp-block-quote-is-layout-flow"><p>“If my GraphQL server accepts and executes any query sent to it, how can I prevent malicious clients from querying too much data, or sending really expensive queries?”</p></blockquote>



<p class="wp-block-paragraph">Well, one answer is to introduce a complexity measurement for queries, or to limit the length of time they can spend executing. But here’s how Facebook does it:</p>



<ol class="wp-block-list"><li>In development mode, the server accepts any query you throw at it.</li><li>When you deploy your code, all of the queries are saved to a database.</li><li>In production, the server only supports the queries that have been previously stored.</li></ol>



<p class="wp-block-paragraph">As an added bonus, this enables Facebook to save bandwidth by not sending the entire query string (the mobile news feed query was many kilobytes in size). Since all of the queries are already stored on the server, they just need to send a query ID and the pre-validated query is looked up directly.</p>



<p class="wp-block-paragraph">This means you no longer have to worry about arbitrary queries hitting your server in production, and it’s very easy to identify which query is causing a performance issue since you can just look up the ID.</p>



<p class="wp-block-paragraph">Currently none of the open source GraphQL clients include tools to enable this, but the next version of Apollo Client will have a tool to pull queries out of your code and save them. The ability to use persisted queries is also one of the reasons Relay 2 will have a much more static architecture, which is critical for production use at Facebook.</p>

A common language for data fetching</h2>



<p class="wp-block-paragraph">There’s one more important reason why you should write GraphQL queries directly in your code rather than using a dynamic query builder: It’s amazing to be able to use a GraphiQL to explore the data available from your API, then paste that query into your UI code and be good to go. Having a shared language to talk about data fetching is extremely useful to be able to share tools and vocabulary across different apps.</p>



<p class="wp-block-paragraph">The API developers can easily read any query across any client codebase and see what the data requirements are, and the UI developers can look into the server logs to identify why their queries are taking longer than expected. This kind of communication is facilitated by the static and language-agnostic nature of GraphQL.</p>



<hr class="wp-block-separator"/>



<p class="wp-block-paragraph">After talking with Facebook, building our own tools, and writing several production apps in GraphQL, we’re pretty convinced that using static GraphQL queries in UI code is the right approach. You can expect to see our open source tools, like the Apollo JS Client, Apollo iOS, and the Apollo GraphQL server, gaining features to better enable this approach soon.</p>



<p class="wp-block-paragraph">If this is something you’re interested in, let’s work together! Getting complete code generation for a variety of typed languages and building tools to collect queries from the UI and persist them to the server is going to require a lot of collaboration across the whole GraphQL ecosystem.</p>



<p class="wp-block-paragraph">Today, we’ve only scratched the surface of the tooling that could be built around GraphQL clients and servers. There are so many more benefits to be gained.</p>


5 benefits of static GraphQL queries


<figure class="wp-block-image"><img decoding="async" src="https://miro.medium.com/max/3038/1*h1RDyEx7ccDzrxK86tgjfg.png" alt=""/><figcaption>This is a specific collection of packages we put together for a Node.js server and a JavaScript client, but an equivalent set of packages can and should exist for every server and client platform.</figcaption></figure>



<p class="wp-block-paragraph">Real-time subscriptions have been an exciting topic in the GraphQL community almost from the start.&nbsp;<a href="https://medium.com/u/8d9de11eda52?source=post_page-----1d89b1934c18----------------------" target="_blank" rel="noreferrer noopener">Laney Kuenzel</a>&nbsp;has given several talks about&nbsp;<a href="https://medium.com/apollo-stack/new-features-in-graphql-batch-defer-stream-live-and-subscribe-7585d0c28b07#.n5am6tg1c" target="_blank" rel="noreferrer noopener">Facebook’s internal implementation of subscriptions</a>, and there have been a few community implementations. Unfortunately, a lot of these have been coupled to specific frameworks or application architectures, so it’s been hard for GraphQL subscriptions to take off as a standard.</p>



<p class="wp-block-paragraph">We wanted to build something anyone can integrate into their servers and clients, without reinventing the common features any implementation would need. That way, as a community we can start building and sharing integrations for different backends, such as Redis, PostgreSQL triggers, Kafka, and more.</p>



<p class="wp-block-paragraph">That’s why we are shipping an open-source GraphQL subscriptions implementation designed to be as general as possible.</p>

<p class="wp-block-paragraph">Today, I’d like to introduce you to two packages in particular:</p>



<ol class="wp-block-list"><li><a href="https://github.com/apollostack/graphql-subscriptions" target="_blank" rel="noreferrer noopener"><strong>graphql-subscriptions</strong></a>, a package you can use to manage parsing, pub/sub handling, and execution for GraphQL subscriptions with GraphQL.js, Facebook’s reference JavaScript implementation. This is completely transport and backend independent, and only implements the kinds of things we think could be part of the spec for GraphQL subscriptions some day.</li><li><a href="https://github.com/apollostack/subscriptions-transport-ws" target="_blank" rel="noreferrer noopener"><strong>subscriptions-transport-ws</strong></a>, a server and client implementation of a simple Websocket protocol for GraphQL subscriptions. This is not coupled to any specific GraphQL clients, and can be used from Apollo, Relay, or just plain JavaScript. It implements subscribing, unsubscribing, and receiving new results or errors for subscriptions. You can easily run it alongside your HTTP server, and plug it into your schema via the graphql-subscriptions package above.</li></ol>



<p class="wp-block-paragraph">We’re getting started on integrating GraphQL subscriptions into our production apps, but we wanted to open source the tools above up front, so that we can all work together on them as a community. If this sounds interesting, try them out, and open an issue or maybe file a PR with an improvement.</p>

<p class="wp-block-paragraph"><a href="https://github.com/apollostack/graphql-subscriptions" target="_blank" rel="noreferrer noopener">GitHub</a>,&nbsp;<a href="https://www.npmjs.com/package/graphql-subscriptions" target="_blank" rel="noreferrer noopener">npm</a></p>



<p class="wp-block-paragraph">When you build an HTTP-based GraphQL server in JavaScript, you usually use Facebook’s reference GraphQL.js execution engine, which accepts a query string and a schema and returns a result. The&nbsp;<em>graphql-subscriptions</em>&nbsp;package is a small wrapper around GraphQL.js that can execute subscriptions as well.</p>



<p class="wp-block-paragraph">The main component of&nbsp;<em>graphql-subscriptions</em>&nbsp;is the&nbsp;<strong>SubscriptionManager</strong>, which takes a schema, a pub-sub handler, and some optional configuration in the form of&nbsp;<em>setup functions</em>, and creates an object which can execute subscriptions in response to pub-sub events.</p>



<p class="wp-block-paragraph">What is a&nbsp;<em>setup function</em>? Well, it’s simple. While queries and mutations execute in one step, GraphQL subscriptions run in two steps:</p>



<ol class="wp-block-list"><li>Receive the subscription string, validate it, store it, and set up any state necessary on the server to subscribe to the right channels.</li><li>Receive a pub-sub message on some channel, execute the subscription, and send the result to the client.</li></ol>



<p class="wp-block-paragraph">The second step is handled by your GraphQL resolvers, as usual. But the first is a new thing, and that’s what the setup functions in the GraphQL subscriptions package do. By default, they just use the subscription field as the channel name, which makes it easy to write simple demos.</p>



<p class="wp-block-paragraph">The best part about <em>graphql-subscriptions</em> is that it’s totally decoupled from the pub-sub system and transport you are using. For example, you can plug it into a <a rel="noreferrer noopener" href="https://medium.com/apollo-stack/graphql-subscriptions-with-redis-pub-sub-f636fc84a0c4#.i7bxnctwy" target="_blank">Redis implementation</a> we recently blogged about. What about the transport? Well, before we move on to the transport, let’s run some very simple GraphQL subscriptions using just GraphQL.js and the <em>graphql-subscriptions</em> package:</p>



<pre class="wp-block-prismatic-blocks"><code class="language-javascript" data-line="">// npm install graphql graphql-tools graphql-subscriptions
const { PubSub, SubscriptionManager } = require(&#039;graphql-subscriptions&#039;);
const { makeExecutableSchema } = require(&#039;graphql-tools&#039;);

// Our &quot;database&quot;
const messages = [];

// Minimal schema
const typeDefs = `
type Query {
  messages: [String!]!
}
type Subscription {
  newMessage: String!
}
`;

// Minimal resolvers
const resolvers = {
  Query: { messages: () =&gt; messages },
  // This just passes through the pubsub message contents
  Subscription: { newMessage: (rootValue) =&gt; rootValue },
};

// Use graphql-tools to make a GraphQL.js schema
const schema = makeExecutableSchema({ typeDefs, resolvers });

// Initialize GraphQL subscriptions
const pubsub = new PubSub();
const subscriptionManager = new SubscriptionManager({ schema, pubsub });

// Run a subscription
subscriptionManager.subscribe({
  query: `
    subscription NewMessageSubscription {
      newMessage
    }
  `,
  callback: (err, result) =&gt;
    console.log(`New message: ${result.data.newMessage}`),
});

// Create a message
const helloWorldMessage = &#039;Hello, world!&#039;;

// Add it to &quot;database&quot;
messages.push(helloWorldMessage);

// Push it over pubsub, this could be replaced with Redis easily
pubsub.publish(&#039;newMessage&#039;, helloWorldMessage);

// Prints &quot;New message: Hello, world!&quot; in the console via the subscription!</code></pre>



<p class="wp-block-paragraph">As you can see, the&nbsp;<em>graphql-subscriptions</em>&nbsp;package is the only thing you need to start running subscriptions against your schema and getting updates. Just like there is often one popular GraphQL execution engine for each server-side language, we think there should be one core subscription implementation, so that people can target it when writing tools and backend integrations. See how this is possible by&nbsp;<a href="https://medium.com/apollo-stack/graphql-subscriptions-with-redis-pub-sub-f636fc84a0c4#.wejfu4x6i" target="_blank" rel="noreferrer noopener">reading about the Redis integration</a>.</p>



<p class="wp-block-paragraph">But it’s not quite enough to go off and write a real app; you also need some way to get those results from a client. That’s where the transport comes in.</p>

<p class="wp-block-paragraph"><a href="https://github.com/apollostack/subscriptions-transport-ws" target="_blank" rel="noreferrer noopener">GitHub</a>,&nbsp;<a href="https://www.npmjs.com/package/subscriptions-transport-ws" target="_blank" rel="noreferrer noopener">npm</a></p>



<p class="wp-block-paragraph">This package includes a client and server that works with&nbsp;<em>graphql-subscriptions</em>&nbsp;from above. It defines a minimal websocket protocol that only includes support for starting and stopping subscriptions, and receiving data. It doesn’t even support queries and mutations, since we think it’s currently best to do those over the more standard HTTP transport. Here’s a summary of the messages used by the transport at the time of writing:</p>



<ul class="wp-block-list"><li>Client to server: SUBSCRIPTION_START, SUBSCRIPTION_END</li><li>Server to client: SUBSCRIPTION_SUCCESS, SUBSCRIPTION_FAIL, SUBSCRIPTION_DATA</li></ul>



<p class="wp-block-paragraph">As you can see, there is nothing extra in there — just the minimal set of operations needed to run subscriptions. It’s designed to run alongside your existing GraphQL setup.</p>



<p class="wp-block-paragraph">Here’s how easy it is to add GraphQL subscriptions to a basic Node server using this package:</p>



<pre class="wp-block-preformatted">import { createServer } from 'http';<br>import { SubscriptionServer } from 'subscriptions-transport-ws';const websocketServer = createServer((request, response) =&gt; {<br>  response.writeHead(404);<br>  response.end();<br>});<br><br>websocketServer.listen(WS_PORT, () =&gt; console.log(<br>  `Websocket Server is now running on http://localhost:${WS_PORT}`<br>));<br><br>new SubscriptionServer(<br>  { subscriptionManager },<br>  websocketServer<br>);</pre>



<p class="wp-block-paragraph">As you can see we just pass the&nbsp;<em>subscriptionManager</em>&nbsp;we created above into a new&nbsp;<strong>SubscriptionServer</strong>&nbsp;instance, which attaches itself to a regular Node web server. You can also pass any options you need, such as a per-subscription&nbsp;<em>context</em>.</p>



<p class="wp-block-paragraph">Now let’s try calling this subscription over the network, instead of before when we had it in-process!</p>



<h2 class="wp-block-heading" id="3920"><a href="#running-a-simple-subscription-in-js" aria-hidden="true" class="aal_anchor" id="running-a-simple-subscription-in-js"><svg aria-hidden="true" class="aal_svg" height="16" version="1.1" viewBox="0 0 16 16" width="16"><path fill-rule="evenodd" d="M4 9h1v1H4c-1.5 0-3-1.69-3-3.5S2.55 3 4 3h4c1.45 0 3 1.69 3 3.5 0 1.41-.91 2.72-2 3.25V8.59c.58-.45 1-1.27 1-2.09C10 5.22 8.98 4 8 4H4c-.98 0-2 1.22-2 2.5S3 9 4 9zm9-3h-1v1h1c1 0 2 1.22 2 2.5S13.98 12 13 12H9c-.98 0-2-1.22-2-2.5 0-.83.42-1.64 1-2.09V6.25c-1.09.53-2 1.84-2 3.25C6 11.31 7.55 13 9 13h4c1.45 0 3-1.69 3-3.5S14.5 6 13 6z"></path></svg></a>Running a simple subscription in JS</h2>



<p class="wp-block-paragraph">Luckily, the <em>subscriptions-transport-ws</em> package also includes a handy client implementation, which we can use to connect to our server and run some subscriptions:</p>



<pre class="wp-block-prismatic-blocks"><code class="language-javascript" data-line="">// To run this code yourself:
// 1. Download and run the demo server: https://github.com/apollostack/frontpage-server
// 2. Use create-react-app to create a build system
// 3. npm install subscriptions-transport-ws
// 4. Replace all of the code in src/ with just this file

import { Client } from &#039;subscriptions-transport-ws&#039;;

const client = new Client(&#039;ws://localhost:8090&#039;);

client.subscribe({
  query: `
    subscription UpvotedPostSubscription {
      postUpvoted {
        title
        votes
      }
    }
  `
}, (err, res) =&gt; {
  if (err) {
    console.error(err);
    return;
  }

  console.log(`&quot;${res.postUpvoted.title}&quot; has ${res.postUpvoted.votes} votes now.`);
})</code></pre>



<p class="wp-block-paragraph">As you can see, this package is very tiny. It only implements the transport, and doesn’t integrate with any fancy libraries, providing only a basic callback-style interface. Together, we can easily set this up to work with observables, Redux, Apollo, Relay, and any other client-side technology we like to use in our apps.</p>



<h2 class="wp-block-heading" id="4fb9"><a href="#the-future" aria-hidden="true" class="aal_anchor" id="the-future"><svg aria-hidden="true" class="aal_svg" height="16" version="1.1" viewBox="0 0 16 16" width="16"><path fill-rule="evenodd" d="M4 9h1v1H4c-1.5 0-3-1.69-3-3.5S2.55 3 4 3h4c1.45 0 3 1.69 3 3.5 0 1.41-.91 2.72-2 3.25V8.59c.58-.45 1-1.27 1-2.09C10 5.22 8.98 4 8 4H4c-.98 0-2 1.22-2 2.5S3 9 4 9zm9-3h-1v1h1c1 0 2 1.22 2 2.5S13.98 12 13 12H9c-.98 0-2-1.22-2-2.5 0-.83.42-1.64 1-2.09V6.25c-1.09.53-2 1.84-2 3.25C6 11.31 7.55 13 9 13h4c1.45 0 3-1.69 3-3.5S14.5 6 13 6z"></path></svg></a>The future</h2>



<p class="wp-block-paragraph">We hope that by the end of the year GraphQL subscriptions are going to be one of the three main operations people expect from their server:&nbsp;<em>query, mutation, and subscription</em>.</p>



<p class="wp-block-paragraph">To make this happen, there is still some work to do:</p>



<ol class="wp-block-list"><li><strong>Servers:</strong>&nbsp;We’re excited to work with GraphQL server authors to implement support for a&nbsp;<a href="https://github.com/apollostack/subscriptions-transport-ws" target="_blank" rel="noreferrer noopener">common transport</a>, and work on other pub-sub plugins for Kafka, Postgres triggers, and more. Let us know if you’re interested!</li><li><strong>Clients:</strong>&nbsp;Apollo has support for subscriptions built in, and we should add integration with other frontend libraries and tools such as Relay and GraphiQL.</li><li><strong>Spec:</strong>&nbsp;We’re working hard to figure out what parts of GraphQL subscriptions are common to all implementations, and should be core to the GraphQL specification. Look out for a post about this soon!</li></ol>



<p class="wp-block-paragraph">The coolest thing about GraphQL is that it’s an open spec and community, not just one implementation. So let’s work together to move it into the future!</p>


A proposal for GraphQL subscriptions


<p class="wp-block-paragraph">If you haven’t visited Apollo’s&nbsp;<a href="http://dev.apollodata.com/" target="_blank" rel="noreferrer noopener">documentation</a>&nbsp;in a while, you might notice it’s a little different now— we’ve recently overhauled our developer site from the ground up.</p>



<figure class="wp-block-image alignfull size-large"><img loading="lazy" decoding="async" width="1024" height="969" src="https://apollographql.wpengine.com/wp-content/uploads/2020/03/1_Z5wCLKPwTWDGzDJja-ZDSA-1024x969.png" alt="" class="wp-image-379" srcset="https://wp.apollographql.com/wp-content/uploads/2020/03/1_Z5wCLKPwTWDGzDJja-ZDSA-1024x969.png 1024w, https://wp.apollographql.com/wp-content/uploads/2020/03/1_Z5wCLKPwTWDGzDJja-ZDSA-300x284.png 300w, https://wp.apollographql.com/wp-content/uploads/2020/03/1_Z5wCLKPwTWDGzDJja-ZDSA-768x727.png 768w, https://wp.apollographql.com/wp-content/uploads/2020/03/1_Z5wCLKPwTWDGzDJja-ZDSA-1200x1136.png 1200w, https://wp.apollographql.com/wp-content/uploads/2020/03/1_Z5wCLKPwTWDGzDJja-ZDSA.png 1210w" sizes="auto, (max-width: 1024px) 100vw, 1024px" /></figure>



<p class="wp-block-paragraph">The new site is about a lot more than a beautiful new theme however; we’ve totally restructured how our documentation is organized.</p>



<h2 class="wp-block-heading" id="88e2"><a href="#guide-oriented-documentation" aria-hidden="true" class="aal_anchor" id="guide-oriented-documentation"><svg aria-hidden="true" class="aal_svg" height="16" version="1.1" viewBox="0 0 16 16" width="16"><path fill-rule="evenodd" d="M4 9h1v1H4c-1.5 0-3-1.69-3-3.5S2.55 3 4 3h4c1.45 0 3 1.69 3 3.5 0 1.41-.91 2.72-2 3.25V8.59c.58-.45 1-1.27 1-2.09C10 5.22 8.98 4 8 4H4c-.98 0-2 1.22-2 2.5S3 9 4 9zm9-3h-1v1h1c1 0 2 1.22 2 2.5S13.98 12 13 12H9c-.98 0-2-1.22-2-2.5 0-.83.42-1.64 1-2.09V6.25c-1.09.53-2 1.84-2 3.25C6 11.31 7.55 13 9 13h4c1.45 0 3-1.69 3-3.5S14.5 6 13 6z"></path></svg></a>Guide-oriented documentation</h2>



<p class="wp-block-paragraph">The vision was to structure the documentation as a guide to help you get your app built, rather than a dry list of API functions (although we still do have&nbsp;<a href="http://dev.apollodata.com/core/apollo-client-api.html" target="_blank" rel="noreferrer noopener">API docs</a>&nbsp;of course!).</p>



<p class="wp-block-paragraph">With that in mind, we’ve produced two primary guides for our JavaScript GraphQL client — one for&nbsp;<a href="http://dev.apollodata.com/react" target="_blank" rel="noreferrer noopener">React</a>&nbsp;and one for&nbsp;<a href="http://dev.apollodata.com/angular2" target="_blank" rel="noreferrer noopener">Angular 2</a>. These are the the view layers that have the most mature integrations with Apollo, and as such we’ve tried to orient our documentation around how to get things done with those technologies.</p>



<p class="wp-block-paragraph">As an example, rather than describing Apollo’s&nbsp;<a href="http://dev.apollodata.com/core/apollo-client-api.html#ApolloClient\.mutate" target="_blank" rel="noreferrer noopener">Optimistic UI</a>&nbsp;support in the abstract as an API for our vanilla JS library, and leaving it up to you to figure out how to use it, we show you exactly how to use it in both&nbsp;<a href="http://dev.apollodata.com/react/optimistic-ui.html" target="_blank" rel="noreferrer noopener">React</a>&nbsp;and&nbsp;<a href="http://dev.apollodata.com/angular2/optimistic-ui.html" target="_blank" rel="noreferrer noopener">Angular</a>, with appropriate code examples for each.</p>



<p class="wp-block-paragraph">Hopefully our list of recipes gives you the boost you need to get your GraphQL-based application off the ground and lets you focus on what actually matters: your app!</p>



<p class="wp-block-paragraph">As a bonus, this round of documentation updates includes a first explanation of how to start using our&nbsp;<a href="https://medium.com/apollo-stack/bringing-graphql-to-ios-fc46423befa1#.gvtmdc9dh" target="_blank" rel="noreferrer noopener">iOS client</a>&nbsp;and some information about how to get more involved in our&nbsp;<a href="http://dev.apollodata.com/community/" target="_blank" rel="noreferrer noopener">developer community</a>.</p>

<p class="wp-block-paragraph">Those snippets use a simple, common “Hello World” example&nbsp;<a href="https://github.com/apollostack/frontpage-api" target="_blank" rel="noreferrer noopener">server</a>&nbsp;and show you how to implement the same basic list query and mutation.

Documenting Apollo


<p class="wp-block-paragraph"><em>Editor’s note: This post is from Guillaume Chau, an Apollo contributor who built an integration package between VueJS and Apollo. Check it out and contribute to it&nbsp;</em><a href="https://github.com/Akryum/vue-apollo" target="_blank" rel="noreferrer noopener"><em>here</em></a><em>!</em></p>



<p class="wp-block-paragraph">As you may know, the Apollo team has built a great GraphQL client and tooling that makes it easy to use data from your server in any JavaScript app. Why not use it with another amazing technology like&nbsp;<a href="https://vuejs.org/" target="_blank" rel="noreferrer noopener">VueJS</a>?</p>



<p class="wp-block-paragraph">Now you can do just that with&nbsp;<a href="https://github.com/Akryum/vue-apollo" target="_blank" rel="noreferrer noopener">vue-apollo</a>, an npm package I wrote that allows you to write GraphQL queries in your VueJS components while using Apollo under the hood.</p>

<p class="wp-block-paragraph">First, install these packages in your project folder:</p>



<blockquote class="wp-block-quote is-layout-flow wp-block-quote-is-layout-flow"><p>npm install — save apollo-client vue-apollo</p></blockquote>



<p class="wp-block-paragraph">Then, you need to create an Apollo client and install the vue-apollo plugin into VueJS:</p>



<pre class="wp-block-prismatic-blocks"><code class="language-javascript" data-line="">import Vue from &#039;vue&#039;;
import App from &#039;./App.vue&#039;;
import ApolloClient, { createNetworkInterface, addTypename } from &#039;apollo-client&#039;;
import VueApollo from &#039;vue-apollo&#039;;

// Create the apollo client
const apolloClient = new ApolloClient({
  networkInterface: createNetworkInterface({
    uri: &#039;http://localhost:8080/graphql&#039;,
    transportBatching: true,
  }),
  queryTransformer: addTypename,
  dataIdFromObject: r =&gt; r.id,
});

// Install the vue plugin
// With the apollo client instance
Vue.use(VueApollo, {
  apolloClient,
});

// Start the Vue app
new Vue({
  el: &#039;#app&#039;,
  render: h =&gt; h(App)
});</code></pre>



<h3 class="wp-block-heading" id="8aba"><a href="#fetch-data-with-graphql-queries" aria-hidden="true" class="aal_anchor" id="fetch-data-with-graphql-queries"><svg aria-hidden="true" class="aal_svg" height="16" version="1.1" viewBox="0 0 16 16" width="16"><path fill-rule="evenodd" d="M4 9h1v1H4c-1.5 0-3-1.69-3-3.5S2.55 3 4 3h4c1.45 0 3 1.69 3 3.5 0 1.41-.91 2.72-2 3.25V8.59c.58-.45 1-1.27 1-2.09C10 5.22 8.98 4 8 4H4c-.98 0-2 1.22-2 2.5S3 9 4 9zm9-3h-1v1h1c1 0 2 1.22 2 2.5S13.98 12 13 12H9c-.98 0-2-1.22-2-2.5 0-.83.42-1.64 1-2.09V6.25c-1.09.53-2 1.84-2 3.25C6 11.31 7.55 13 9 13h4c1.45 0 3-1.69 3-3.5S14.5 6 13 6z"></path></svg></a>Fetch data with GraphQL queries</h3>



<p class="wp-block-paragraph">You can now use Apollo directly in your components to query your GraphQL server. Inside a component, the Apollo client can be accessed with ‘this.$apollo’:</p>



<pre class="wp-block-prismatic-blocks"><code class="language-markup" data-line="">&lt;script&gt;
export default {
  created() {
    this.$apollo.watchQuery({
      /* options */
    }).then(data =&gt; {
      console.log(data);
    });
  },
};
&lt;/script&gt;</code></pre>



<p class="wp-block-paragraph">But the preferred way to make queries is to declare them with the ‘apollo’ option in the component definition:</p>



<pre class="wp-block-prismatic-blocks"><code class="language-markup" data-line="">&lt;script&gt;
import gql from &#039;graphql-tag&#039;;
// GraphQL query
const postsQuery = gql`
  query allPosts {
    posts {
      id
      title
      votes
      author {
        id
        firstName
        lastName
      }
    }
  }
`;
// Vue component definition
export default {
  // Local state
  data: () =&gt; ({
    // You can initialize the &#039;posts&#039; data here
    posts: [],
    loading: 0,
  }),
  // Apollo GraphQL
  apollo: {
    // Local state &#039;posts&#039; data will be updated
    // by the GraphQL query result
    posts: {
      // GraphQL query
      query: postsQuery,
      // Will update the &#039;loading&#039; attribute
      // +1 when a new query is loading
      // -1 when a query is completed
      loadingKey: &#039;loading&#039;,
    },
  },
};
&lt;/script&gt;

&lt;template&gt;
  &lt;div class=&quot;post-list&quot;&gt;
    &lt;!-- If there is one or more queries loading --&gt;
    &lt;template v-if=&quot;loading &gt; 0&quot;&gt;
      Loading
    &lt;/template&gt;
    &lt;!-- Actual view --&gt;
    &lt;template v-else&gt;
      &lt;ul&gt;
        &lt;!-- Post list items --&gt;
        &lt;li v-for=&quot;post in posts&quot; :key=&quot;post.id&quot;&gt;
          {{ post.title }} by
          {{ post.author.firstName }} {{ post.author.lastName }}
        &lt;/li&gt;
      &lt;/ul&gt;
    &lt;/template&gt;
  &lt;/div&gt;
&lt;/template&gt;</code></pre>



<p class="wp-block-paragraph">Thanks to the VueJS reactivity system, the ‘posts’ local data will be automatically updated with the GraphQL query result and your DOM updated.</p>



<p class="wp-block-paragraph">You can initialize the corresponding data attribute in the ‘data’ hook with a default value:</p>



<pre class="wp-block-prismatic-blocks"><code class="language-javascript" data-line="">
  // Local state
  data: () =&gt; ({
    // You can initialize the &#039;posts&#039; data here
    posts: [],
    loading: 0,
  }),</code></pre>



<p class="wp-block-paragraph">If you want to update your data automatically when another user changes it, you can poll the server with the ‘pollInterval’ option, specifying an interval duration in milliseconds:</p>



<pre class="wp-block-prismatic-blocks"><code class="language-javascript" data-line="">
  apollo: {
    posts: {
      query: postsQuery,
      loadingKey: &#039;loading&#039;,
      // Polling query
      pollInterval: 300, // ms
    },
  },</code></pre>

<p class="wp-block-paragraph">In the component methods and hooks, you can use the ‘$apollo’ object to call mutations:</p>



<pre class="wp-block-prismatic-blocks"><code class="language-markup" data-line="">&lt;script&gt;
import gql from &#039;graphql-tag&#039;;
// GraphQL Mutation with one parameter
const upvoteMutation = gql`
  mutation upvotePost($postId: Int!) {
    upvotePost(postId: $postId) {
      id
      votes
    }
  }
`;
export default {
  // Attribute
  props: {
    // Post id passed down to this component
    postId: {
      type: Number,
      required: true,
    },
  },
  methods: {
    upvote() {
      // Mutation
      this.$apollo.mutate({
        mutation: upvoteMutation,
        variables: {
          postId: this.postId,
        },
      }).then(data =&gt; {
        console.log(&#039;Done upvoting.&#039;);
      });
    },
  },
};
&lt;/script&gt;

&lt;template&gt;
  &lt;button @click=&quot;upvote&quot;&gt;Upvote&lt;/button&gt;
&lt;/template&gt;</code></pre>



<p class="wp-block-paragraph">In this component, we call the ‘upvotePost’ mutation on the GraphQL server, that returns the updated post data. That way, the Apollo cache is up-to-date, and again, thanks to VueJS reactivity system, your view should reflect the new votes count.</p>

Native code generation at Facebook


<p class="wp-block-paragraph">As some of you may know, GraphQL was originally developed for the Facebook iOS team, and it has powered the main Facebook iOS app since 2012.</p>



<p class="wp-block-paragraph">Outside of Facebook however, GraphQL on the client is still mostly associated with JavaScript. By now, there are dozens of GraphQL libraries in other languages available, including implementations in&nbsp;<a href="https://github.com/rmosolgo/graphql-ruby" target="_blank" rel="noreferrer noopener">Ruby</a>,&nbsp;<a href="https://github.com/graphql-python/graphene" target="_blank" rel="noreferrer noopener">Python</a>,&nbsp;<a href="https://github.com/graphql-java/graphql-java" target="_blank" rel="noreferrer noopener">Java</a>,&nbsp;<a href="https://github.com/sangria-graphql/sangria" target="_blank" rel="noreferrer noopener">Scala</a>, and&nbsp;<a href="https://github.com/graphql-dotnet/graphql-dotnet" target="_blank" rel="noreferrer noopener">.NET</a>, but these only cover the server side.</p>



<p class="wp-block-paragraph">We believe GraphQL is a great match for native mobile apps, so as a first step we’ve started working on a GraphQL client for iOS. The main design goal of the current version of Apollo iOS is to return typed results for GraphQL queries.</p>

<p class="wp-block-paragraph">Performing a GraphQL request is actually pretty straightforward. If you send an HTTP request with a query string to a GraphQL server, you get back a JSON response:</p>



<figure class="wp-block-image size-large"><img loading="lazy" decoding="async" width="1024" height="372" src="https://apollographql.wpengine.com/wp-content/uploads/2020/03/1_9hZQs9FUPn8O3p8OFz2dEA-1024x372.png" alt="" class="wp-image-350" srcset="https://wp.apollographql.com/wp-content/uploads/2020/03/1_9hZQs9FUPn8O3p8OFz2dEA-1024x372.png 1024w, https://wp.apollographql.com/wp-content/uploads/2020/03/1_9hZQs9FUPn8O3p8OFz2dEA-300x109.png 300w, https://wp.apollographql.com/wp-content/uploads/2020/03/1_9hZQs9FUPn8O3p8OFz2dEA-768x279.png 768w, https://wp.apollographql.com/wp-content/uploads/2020/03/1_9hZQs9FUPn8O3p8OFz2dEA-1200x436.png 1200w, https://wp.apollographql.com/wp-content/uploads/2020/03/1_9hZQs9FUPn8O3p8OFz2dEA.png 1344w" sizes="auto, (max-width: 1024px) 100vw, 1024px" /></figure>



<p class="wp-block-paragraph">While JSON responses are convenient to work with in dynamic languages like JavaScript, dealing with dictionaries and untyped values is a pain in statically typed languages like Swift.</p>



<p class="wp-block-paragraph">The code you have to write to extract data from a JSON response in Swift quickly gets repetitive and is prone to errors. Even ignoring error reporting, parsing query results manually requires quite a bit of code because it relies on string-based dictionary access and conditional casts:</p>



<figure class="wp-block-image size-large"><img loading="lazy" decoding="async" width="1024" height="118" src="https://apollographql.wpengine.com/wp-content/uploads/2020/03/1_p3GzuIxgeKbt8xUVxPmdLg-1024x118.png" alt="" class="wp-image-349" srcset="https://wp.apollographql.com/wp-content/uploads/2020/03/1_p3GzuIxgeKbt8xUVxPmdLg-1024x118.png 1024w, https://wp.apollographql.com/wp-content/uploads/2020/03/1_p3GzuIxgeKbt8xUVxPmdLg-300x35.png 300w, https://wp.apollographql.com/wp-content/uploads/2020/03/1_p3GzuIxgeKbt8xUVxPmdLg-768x89.png 768w, https://wp.apollographql.com/wp-content/uploads/2020/03/1_p3GzuIxgeKbt8xUVxPmdLg-1536x177.png 1536w, https://wp.apollographql.com/wp-content/uploads/2020/03/1_p3GzuIxgeKbt8xUVxPmdLg-1200x139.png 1200w, https://wp.apollographql.com/wp-content/uploads/2020/03/1_p3GzuIxgeKbt8xUVxPmdLg.png 1766w" sizes="auto, (max-width: 1024px) 100vw, 1024px" /></figure>



<p class="wp-block-paragraph">The repetitive nature of writing well-behaved parsing code is the reason&nbsp;<a href="https://swiftmodules.com/blog/json-parsing-in-swift-pt1" target="_blank" rel="noreferrer noopener">so many JSON libraries have sprung up in the Swift community</a>. While these can make dealing with JSON a lot more convenient and somewhat safer, they do nothing to solve a more fundamental problem with manually writing code to parse query results.</p>



<p class="wp-block-paragraph">Depending on an implicit understanding of the shape and typings of a response makes your parsing code brittle. When query results change, you’ll have to remember to make corresponding changes to your parsing code. Errors may not show up until runtime, or even until a particular response is received in production.</p>



<p class="wp-block-paragraph">GraphQL has been designed from the start to avoid these issues by incorporating strong typing into the language. GraphQL servers define a schema, a type system that precisely describes what data is available to clients, and servers support introspection to access the type information. Queries are written against a particular schema, and this allows for&nbsp;<a href="https://medium.com/apollo-stack/power-tools-for-your-api-42529706ae78#.u98zo1nxl" target="_blank" rel="noreferrer noopener">powerful developer tools</a>&nbsp;like autocompletion and validation.</p>

<p class="wp-block-paragraph">The strongly-typed nature of GraphQL is a great match for native development. Within Facebook, the iOS and Android teams have long relied on code generation to generate native model classes that know how to parse raw JSON into properly typed data objects.</p>



<p class="wp-block-paragraph">Apollo iOS has been built around the same process. We integrate with the Xcode build process to generate Swift types from a GraphQL schema and a set of query documents. At runtime, query results are parsed into query-specific nested structs, which allows us to write code like this:</p>



<figure class="wp-block-image size-large"><img loading="lazy" decoding="async" width="1024" height="43" src="https://apollographql.wpengine.com/wp-content/uploads/2020/03/1_K2KhR6Uiy9YB2j3PcwiIYw-1024x43.png" alt="" class="wp-image-348" srcset="https://wp.apollographql.com/wp-content/uploads/2020/03/1_K2KhR6Uiy9YB2j3PcwiIYw-1024x43.png 1024w, https://wp.apollographql.com/wp-content/uploads/2020/03/1_K2KhR6Uiy9YB2j3PcwiIYw-300x13.png 300w, https://wp.apollographql.com/wp-content/uploads/2020/03/1_K2KhR6Uiy9YB2j3PcwiIYw-768x32.png 768w, https://wp.apollographql.com/wp-content/uploads/2020/03/1_K2KhR6Uiy9YB2j3PcwiIYw-1536x64.png 1536w, https://wp.apollographql.com/wp-content/uploads/2020/03/1_K2KhR6Uiy9YB2j3PcwiIYw-1200x50.png 1200w, https://wp.apollographql.com/wp-content/uploads/2020/03/1_K2KhR6Uiy9YB2j3PcwiIYw.png 1766w" sizes="auto, (max-width: 1024px) 100vw, 1024px" /></figure>



<p class="wp-block-paragraph">Instead of passing around dictionaries and making clients cast values to the right type manually, these generated types allow you to access data and navigate relationships using the appropriate native types directly.</p>



<p class="wp-block-paragraph">Being able to rely on the Swift type checker means that errors in data access now show up at compile time. The type system guarantees that the data we access from our code is actually fetched as part of the query:</p>

<p class="wp-block-paragraph">Apollo iOS is still at its early stages, but we hope you’ll want to give it a try and report back on your experiences. The easiest way to get started is through&nbsp;<a href="https://github.com/apollostack/apollo-ios-quickstart" target="_blank" rel="noreferrer noopener">Apollo iOS Quickstart</a>, which contains a sample app and playgrounds that allow you to experiment with query results for particular APIs (including your own).</p>



<p class="wp-block-paragraph">One of the things we’re trying to figure out is what a good native workflow for developing with GraphQL looks like. Even with the limited extensibility of the current version of Xcode, we’ve been able to achieve some neat integrations, like showing inline validation errors for GraphQL documents as part of the build process:</p>

<p class="wp-block-paragraph">Apollo iOS is under active development, and there is plenty to work on, but we want to ensure we’re addressing real needs, and prioritizing features accordingly. So if you’re using or planning to use GraphQL in an iOS app, please&nbsp;<a href="http://apollostack.com/#slack" target="_blank" rel="noreferrer noopener">get in touch on the #ios channel on Slack</a>.</p>



<p class="wp-block-paragraph">Although we’ve chosen to start with iOS, we’re excited about bringing Apollo to more platforms in the future. We expect much of the design of an Android version to carry over from iOS, and we should even be able to reuse parts of the code generation tool. There has been some interest from the community in helping to bring Apollo Android to life faster, so if you’d like to contribute to that effort, please&nbsp;<a href="http://apollostack.com/#slack" target="_blank" rel="noreferrer noopener">let us know on the #android channel on Slack</a>.</p>

Bringing GraphQL to iOS


<p class="wp-block-paragraph">The GraphQL community has been super hyped in the last few days after a truly landmark announcement — the&nbsp;<a href="https://medium.com/apollo-stack/the-new-github-graphql-api-811b005d1b6e#.fhdp8u6ap" target="_blank" rel="noreferrer noopener">first major public GraphQL API</a>. And not just from anyone, from GitHub, one of the most important, developer-oriented API providers out there. While that’s a big piece of news for the wider developer community, and a lot of people will be hearing about GraphQL for the first time because of it, you shouldn’t miss another huge milestone:</p>



<p class="wp-block-paragraph"><strong>GraphQL.org has been rewritten from the ground up, and GraphQL has been announced to be a stable, production ready platform!</strong></p>



<p class="wp-block-paragraph">For the last year, GraphQL has been a bit of a hidden gem — if you put in the effort to learn about it, you got hooked, but there wasn’t one place you could get a great summary of its benefits, an explanation of the technology, and comprehensive learning and “getting started” materials. Now there is!</p>



<p class="wp-block-paragraph">Here are the five best parts of the new GraphQL.org website:</p>

GraphQL.org just got a makeover


<p class="wp-block-paragraph">In September of 2016 GitHub casually dropped some big news when they&nbsp;<a href="http://githubengineering.com/the-github-graphql-api/" target="_blank" rel="noreferrer noopener">officially announced</a>&nbsp;their new GraphQL API and made it available to everyone in&nbsp;<a href="https://developer.github.com/early-access/" target="_blank" rel="noreferrer noopener">early access</a>.</p>



<p class="wp-block-paragraph">In this post I’ll explain the most important things you need to know about GitHub’s GraphQL API:</p>



<ol class="wp-block-list"><li><strong>Why it matters</strong></li><li><strong>What it looks like&nbsp;</strong>(also check out the&nbsp;<a href="https://youtu.be/6xO87LlijoQ" target="_blank" rel="noreferrer noopener">video tour</a>!)</li><li><strong>How you can use it</strong></li><li><strong>What’s coming next</strong></li></ol>



<blockquote class="wp-block-quote is-layout-flow wp-block-quote-is-layout-flow"><p>If you don’t yet know what GraphQL is, go check out the excellent introduction on&nbsp;<a href="http://graphql.org/" target="_blank" rel="noreferrer noopener">graphql.org</a>&nbsp;before reading the rest of this post. You’ll get more out of it.</p></blockquote>

<p class="wp-block-paragraph">For years, GitHub’s REST API has been used by others as a great example of a well-designed REST API, and many companies modeled their REST API after GitHub’s.</p>



<p class="wp-block-paragraph">If GitHub’s REST API was so good, why are they moving to GraphQL? For the same reasons that many other companies have started adopting GraphQL. You can read the details in their&nbsp;<a href="http://githubengineering.com/the-github-graphql-api/" target="_blank" rel="noreferrer noopener">announcement post</a>, but the gist of it is this:</p>



<ul class="wp-block-list"><li>Where REST requires many requests, GraphQL takes just one</li><li>With REST, you request too much or too little data; with GraphQL you request exactly what you need</li><li>REST often turns into a maze of poorly-documented endpoints; GraphQL is strongly-typed and self-documenting</li></ul>



<p class="wp-block-paragraph">In the words of the GitHub platform team:</p>



<blockquote class="wp-block-quote is-layout-flow wp-block-quote-is-layout-flow"><p>GraphQL represents a&nbsp;<strong>massive leap forward for API development</strong>. Type safety, introspection, generated documentation, and predictable responses benefit both the maintainers and consumers of our platform. We’re looking forward to our new era of a GraphQL-backed platform, and we hope that you do, too!</p></blockquote>



<p class="wp-block-paragraph">Thanks to GraphQL, GitHub no longer needs to separately maintain a public and a private API. Instead there will be just one API, used for both.</p>



<p class="wp-block-paragraph">GitHub’s announcement is so significant because their new API is the first large-scale, public GraphQL API, and&nbsp;<strong>where GitHub goes many others will follow.&nbsp;</strong>On top of that, other notable companies are&nbsp;<em>already</em>&nbsp;using GraphQL, including Facebook, Twitter, Intuit, Shopify, and many more. There’s so much interest that the&nbsp;<a href="http://graphqlsummit.com/" target="_blank" rel="noreferrer noopener">first GraphQL conference</a>&nbsp;ever is coming to San Francisco this October.</p>



<p class="wp-block-paragraph">But enough about why this is so exciting, let’s take a look at their actual API.</p>



<h2 class="wp-block-heading" id="c5d7"><a href="#what-it-looks-like" aria-hidden="true" class="aal_anchor" id="what-it-looks-like"><svg aria-hidden="true" class="aal_svg" height="16" version="1.1" viewBox="0 0 16 16" width="16"><path fill-rule="evenodd" d="M4 9h1v1H4c-1.5 0-3-1.69-3-3.5S2.55 3 4 3h4c1.45 0 3 1.69 3 3.5 0 1.41-.91 2.72-2 3.25V8.59c.58-.45 1-1.27 1-2.09C10 5.22 8.98 4 8 4H4c-.98 0-2 1.22-2 2.5S3 9 4 9zm9-3h-1v1h1c1 0 2 1.22 2 2.5S13.98 12 13 12H9c-.98 0-2-1.22-2-2.5 0-.83.42-1.64 1-2.09V6.25c-1.09.53-2 1.84-2 3.25C6 11.31 7.55 13 9 13h4c1.45 0 3-1.69 3-3.5S14.5 6 13 6z"></path></svg></a>What it looks like</h2>



<p class="wp-block-paragraph">If you sign their prerelease agreement, you get early access to the GitHub GraphQL API. I did just that, and then headed straight to the API Explorer.

<p class="wp-block-paragraph">After a couple seconds of typing, I sent my first query and got back a response — it worked! I could have used GraphiQL to explore the schema, but it’s not the easiest way to get a quick overview, so I turned to the&nbsp;<a href="https://developer.github.com/early-access/graphql/" target="_blank" rel="noreferrer noopener">API documentation</a>&nbsp;to find out what queries or mutations I could make. The starting points for queries were pretty much as expected: you can search for things, look up users and organizations, and get info about yourself using the&nbsp;<em>viewer</em>&nbsp;query. From there you can drill deeper and get lists of repositories, which in turn let you get PRs, issues, comments, reactions (the emojis), forks, branches, commits and even the Git trees of individual commits. And that’s really only the tip of the iceberg. Pretty cool, right?</p>



<p class="wp-block-paragraph">Next up, I took a look at the mutations — GraphQL’s way of modifying data. The selection there is a lot more limited. Right now, the only things you can do are comment on issues, add reactions to comments, subscribe/unsubscribe from issues, and manage projects — a new feature GitHub introduced yesterday, and which is powered by GraphQL.</p>



<p class="wp-block-paragraph">Of course, I had to try posting a comment via the new GraphQL API:</p>

<p class="wp-block-paragraph">Here’s a&nbsp;<a href="https://github.com/apollostack/apollo/issues/66" target="_blank" rel="noreferrer noopener">link to the issue</a>. Go give it a try, and see if you can post to it via GitHub’s GraphQL API!</p>



<p class="wp-block-paragraph">Overall, I think the existing parts of the API are already in excellent shape, and there were just a few rough edges:</p>



<ul class="wp-block-list"><li>The API documentation was slightly outdated and incomplete in places. I worked around it by using the introspection query to print myself a neat little schema in GraphQL schema language (<a href="https://gist.github.com/helfer/16ae2323ff3c23cedc69471a973a4f0f" target="_blank" rel="noreferrer noopener">see the schema</a>).</li><li>Connections (<a href="https://medium.com/apollo-stack/understanding-pagination-rest-graphql-and-relay-b10f835549e7" target="_blank" rel="noreferrer noopener">a type of pagination</a>) are used extensively, which can make initial interaction with the API quite confusing for people who are not familiar with connections.</li><li>All mutations take only one input argument, which makes them harder to write and read. This was done because of a&nbsp;<a href="https://github.com/facebook/relay/issues/112" target="_blank" rel="noreferrer noopener">limitation in Relay</a>, but Relay 2 is going to remove that limitation, and&nbsp;<a href="https://github.com/apollostack/apollo-client" target="_blank" rel="noreferrer noopener">Apollo Client</a>&nbsp;already supports multiple arguments today.</li></ul>

<p class="wp-block-paragraph">Once you’ve signed the prerelease agreement, you can start building your own apps against GitHub’s GraphQL API. Technically you can send your GraphQL queries as simple strings in a POST request, but your life is going to be a lot easier if you use a GraphQL client like&nbsp;<a href="https://github.com/apollostack/apollo-client" target="_blank" rel="noreferrer noopener">Apollo Client</a>&nbsp;or&nbsp;<a href="https://github.com/facebook/relay" target="_blank" rel="noreferrer noopener">Relay</a>.</p>
