Major Changes

• #11864 ee38b3a Thanks @ematipico! - ### [changed]: entryPoint type inside the hook astro:build:ssr
  In Astro v4.x, the entryPoint type was RouteData.

  Astro v5.0 the entryPoint type is IntegrationRouteData, which contains a subset of the RouteData type. The fields isIndex and fallbackRoutes were removed.

  What should I do?

  Update your adapter to change the type of entryPoint from RouteData to IntegrationRouteData.

  -import type {RouteData} from 'astro';
  +import type {IntegrationRouteData} from "astro"
  
  -function useRoute(route: RouteData) {
  +function useRoute(route: IntegrationRouteData) {
  
  }

• #11908 518433e Thanks @Princesseuh! - The image.endpoint config now allow customizing the route of the image endpoint in addition to the entrypoint. This can be useful in niche situations where the default route /_image conflicts with an existing route or your local server setup.

  import { defineConfig } from 'astro/config';
  
  defineConfig({
    image: {
      endpoint: {
        route: '/image',
        entrypoint: './src/image_endpoint.ts',
      },
    },
  });

• #11806 f7f2338 Thanks @Princesseuh! - Removes the assets property on supportedAstroFeatures for adapters, as it did not reflect reality properly in many cases.

  Now, relating to assets, only a single sharpImageService property is available, determining if the adapter is compatible with the built-in sharp image service.

• #11864 ee38b3a Thanks @ematipico! - ### [changed]: routes type inside the hook astro:build:done
  In Astro v4.x, the routes type was RouteData.

  Astro v5.0 the routes type is IntegrationRouteData, which contains a subset of the RouteData type. The fields isIndex and fallbackRoutes were removed.

  What should I do?

  Update your adapter to change the type of routes from RouteData to IntegrationRouteData.

  -import type {RouteData} from 'astro';
  +import type {IntegrationRouteData} from "astro"
  
  -function useRoute(route: RouteData) {
  +function useRoute(route: IntegrationRouteData) {
  
  }

• #11864 ee38b3a Thanks @ematipico! - ### [changed]: RouteData.distURL is now an array
  In Astro v4.x, RouteData.distURL was undefined or a URL

  Astro v5.0, RouteData.distURL is undefined or an array of URL. This was a bug, because a route can generate multiple files on disk, especially when using dynamic routes such as [slug] or [...slug].

  What should I do?

  Update your code to handle RouteData.distURL as an array.

  if (route.distURL) {
  -  if (route.distURL.endsWith('index.html')) {
  -    // do something
  -  }
  +  for (const url of route.distURL) {
  +    if (url.endsWith('index.html')) {
  +      // do something
  +    }
  +  }
  }

Minor Changes

• #11806 f7f2338 Thanks @Princesseuh! - The value of the different properties on supportedAstroFeatures for adapters can now be objects, with a support and message properties. The content of the message property will be shown in the Astro CLI when the adapter is not compatible with the feature, allowing one to give a better informational message to the user.

  This is notably useful with the new limited value, to explain to the user why support is limited.

• #11955 d813262 Thanks @matthewp! - Server Islands introduced behind an experimental flag in v4.12.0 is no longer experimental and is available for general use.

  Server islands are Astro's solution for highly cacheable pages of mixed static and dynamic content. They allow you to specify components that should run on the server, allowing the rest of the page to be more aggressively cached, or even generated statically.

  Turn any .astro component into a server island by adding the server:defer directive and optionally, fallback placeholder content. It will be rendered dynamically at runtime outside the context of the rest of the page, allowing you to add longer cache headers for the pages, or even prerender them.

  ---
  import Avatar from '../components/Avatar.astro';
  import GenericUser from '../components/GenericUser.astro';
  ---
  
  <header>
    <h1>Page Title</h1>
    <div class="header-right">
      <Avatar server:defer>
        <GenericUser slot="fallback" />
      </Avatar>
    </div>
  </header>

  If you were previously using this feature, please remove the experimental flag from your Astro config:

  import { defineConfig } from 'astro/config';
  
  export default defineConfig({
    experimental {
  -    serverIslands: true,
    },
  });

  If you have been waiting for stabilization before using server islands, you can now do so.

  Please see the server island documentation for more about this feature.

• #11806 f7f2338 Thanks @Princesseuh! - Adds a new limited value for the different properties of supportedAstroFeatures for adapters, which indicates that the adapter is compatible with the feature, but with some limitations. This is useful for adapters that support a feature, but not in all cases or with all options.

• #11925 74722cb Thanks @florian-lefebvre! - Updates astro/config import to reference astro/client types

  When importing astro/config, types from astro/client will be made automatically available to your project. If your project tsconfig.json changes how references behave, you'll still have access to these types after running astro sync.

Patch Changes

• #11974 60211de Thanks @ascorbic! - Exports the RenderResult type

• #11939 7b09c62 Thanks @bholmesdev! - Adds support for Zod discriminated unions on Action form inputs. This allows forms with different inputs to be submitted to the same action, using a given input to decide which object should be used for validation.

  This example accepts either a create or update form submission, and uses the type field to determine which object to validate against.

  import { defineAction } from 'astro:actions';
  import { z } from 'astro:schema';
  
  export const server = {
    changeUser: defineAction({
      accept: 'form',
      input: z.discriminatedUnion('type', [
        z.object({
          type: z.literal('create'),
          name: z.string(),
          email: z.string().email(),
        }),
        z.object({
          type: z.literal('update'),
          id: z.number(),
          name: z.string(),
          email: z.string().email(),
        }),
      ]),
      async handler(input) {
        if (input.type === 'create') {
          // input is { type: 'create', name: string, email: string }
        } else {
          // input is { type: 'update', id: number, name: string, email: string }
        }
      },
    }),
  };

  The corresponding create and update forms may look like this:

  ---
  import { actions } from 'astro:actions';
  ---
  
  <!--Create-->
  <form action={actions.changeUser} method="POST">
    <input type="hidden" name="type" value="create" />
    <input type="text" name="name" required />
    <input type="email" name="email" required />
    <button type="submit">Create User</button>
  </form>
  
  <!--Update-->
  <form action={actions.changeUser} method="POST">
    <input type="hidden" name="type" value="update" />
    <input type="hidden" name="id" value="user-123" />
    <input type="text" name="name" required />
    <input type="email" name="email" required />
    <button type="submit">Update User</button>
  </form>
