Enhance customer experiences with Apollo GraphOS


<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">Apollo Kotlin 5 comes with a new, separately versioned, normalized cache that supports:</p>



<ul class="wp-block-list">
<li>TTL</li>



<li>Garbage collection</li>



<li>Pagination</li>



<li>Binary format</li>



<li>Partial results</li>

<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">Previous <code class="" data-line="">DeprecationLevel.WARNING</code> symbols are now <code class="" data-line="">DeprecationLevel.ERROR</code>. Previous <code class="" data-line="">DeprecationLevel.ERROR</code> symbols are removed.</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


<p class="wp-block-paragraph">Whether you&#8217;re trying to build a demo, create a workshop, or learn how GraphQL works, it&#8217;s nice to have some examples to reference instead of having to build your own. 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>

<p class="wp-block-paragraph">The GitHub API is one of my favorite APIs for creating examples. It supports both queries and mutations (you can create repositories, add comments to PRs, and more) and has a vast amount of data making it possible to build really in-depth examples and demos or see what GraphQL looks like at scale. <a href="https://studio.apollographql.com/public/github">Try it out here!</a></p>



<blockquote class="wp-block-quote is-layout-flow wp-block-quote-is-layout-flow"><p>While the API is free to use, you will still need to add an Authorization header in Apollo Explorer using a <a href="https://docs.github.com/en/github/authenticating-to-github/keeping-your-account-and-data-secure/creating-a-personal-access-token">personal access token</a>. Check out the <a href="https://docs.github.com/en/graphql/guides/introduction-to-graphql">GitHub API docs</a> for more information.</p></blockquote>
