Major Changes

  • #​15654 a32aee6 Thanks @​florian-lefebvre! - Removes the experimentalErrorPageHost option

    This option allowed fetching a prerendered error page from a different host than the server is currently running on.

    However, there can be security implications with prefetching from other hosts, and often more customization was required to do this safely. This has now been removed as a built-in option so that you can implement your own secure solution as needed and appropriate for your project via middleware.

What should I do?

If you were previously using this feature, you must remove the option from your adapter configuration as it no longer exists:

// astro.config.mjs
import { defineConfig } from 'astro/config'
import node from '@​astrojs/node'

export default defineConfig({
  adapter: node({
    mode: 'standalone',
-    experimentalErrorPageHost: 'http://localhost:4321'
  })
})

You can replicate the previous behavior by checking the response status in a middleware and fetching the prerendered page yourself:

// src/middleware.ts
import { defineMiddleware } from 'astro:middleware';

export const onRequest = defineMiddleware(async (ctx, next) => {
  const response = await next();
  if (response.status === 404 || response.status === 500) {
    return fetch(`http://localhost:4321/${response.status}.html`);
  }
  return response;
});
Minor Changes

  • #​15258 d339a18 Thanks @​ematipico! - Stabilizes the adapter feature experimentalStatiHeaders. If you were using this feature in any of the supported adapters, you'll need to change the name of the flag:

    export default defineConfig({
  adapter: netlify({
-    experimentalStaticHeaders: true
+    staticHeaders: true
  })
})

  • #​15759 39ff2a5 Thanks @​matthewp! - Adds a new bodySizeLimit option to the @astrojs/node adapter

    You can now configure a maximum allowed request body size for your Node.js standalone server. The default limit is 1 GB. Set the value in bytes, or pass 0 to disable the limit entirely:

    import node from '@​astrojs/node';
import { defineConfig } from 'astro/config';

export default defineConfig({
  adapter: node({
    mode: 'standalone',
    bodySizeLimit: 1024 * 1024 * 100, // 100 MB
  }),
});

  • #​15006 f361730 Thanks @​florian-lefebvre! - Adds new session driver object shape

    For greater flexibility and improved consistency with other Astro code, session drivers are now specified as an object:

    -import { defineConfig } from 'astro/config'
+import { defineConfig, sessionDrivers } from 'astro/config'

export default defineConfig({
  session: {
-    driver: 'redis',
-    options: {
-      url: process.env.REDIS_URL
-    },
+    driver: sessionDrivers.redis({
+      url: process.env.REDIS_URL
+    }),
  }
})

    Specifying the session driver as a string has been deprecated, but will continue to work until this feature is removed completely in a future major version. The object shape is the current recommended and documented way to configure a session driver.

  • #​14946 95c40f7 Thanks @​ematipico! - Removes the experimental.csp flag and replaces it with a new configuration option security.csp - (v6 upgrade guidance)

Patch Changes

  • #​15473 d653b86 Thanks @​matthewp! - Improves error page loading to read from disk first before falling back to configured host

  • #​15562 e14a51d Thanks @​florian-lefebvre! - Updates to new Adapter API introduced in v6

  • #​15585 98ea30c Thanks @​matthewp! - Add a default body size limit for server actions to prevent oversized requests from exhausting memory.

  • #​15777 02e24d9 Thanks @​matthewp! - Fixes CSRF origin check mismatch by passing the actual server listening port to createRequest, ensuring the constructed URL origin includes the correct port (e.g., http://localhost:4321 instead of http://localhost). Also restricts X-Forwarded-Proto to only be trusted when allowedDomains is configured.

  • #​15714 9a2c949 Thanks @​ematipico! - Fixes an issue where static headers weren't correctly applied when the website uses base.

  • #​15763 1567e8c Thanks @​matthewp! - Normalizes static file paths before evaluating dotfile access rules for improved consistency

  • #​15164 54dc11d Thanks @​HiDeoo! - Fixes an issue where the Node.js adapter could fail to serve a 404 page matching a pre-rendered dynamic route pattern.

  • #​15745 20b05c0 Thanks @​matthewp! - Hardens static file handler path resolution to ensure resolved paths stay within the client directory

  • #​15495 5b99e90 Thanks @​leekeh! - Refactors to use middlewareMode adapter feature (set to classic)

  • #​15657 cb625b6 Thanks @​qzio! - Adds a new security.actionBodySizeLimit option to configure the maximum size of Astro Actions request bodies.

    This lets you increase the default 1 MB limit when your actions need to accept larger payloads. For example, actions that handle file uploads or large JSON payloads can now opt in to a higher limit.

    If you do not set this option, Astro continues to enforce the 1 MB default to help prevent abuse.

    // astro.config.mjs
export default defineConfig({
  security: {
    actionBodySizeLimit: 10 * 1024 * 1024, // set to 10 MB
  },
});

Minor Changes

  • #​14306 141c4a2 Thanks @​ematipico! - Adds new optional properties to setAdapter() for adapter entrypoint handling in the Adapter API

    Changes:

    • New optional properties:
      • entryType?: 'self' | 'legacy-dynamic' - determines if the adapter provides its own entrypoint ('self') or if Astro constructs one ('legacy-dynamic', default)

    Migration: Adapter authors can optionally add these properties to support custom dev entrypoints. If not specified, adapters will use the legacy behavior.

  • #​15700 4e7f3e8 Thanks @​ocavue! - Updates the internal logic during SSR by providing additional metadata for UI framework integrations.

  • #​15231 3928b87 Thanks @​rururux! - Adds a new optional getRemoteSize() method to the Image Service API.

    Previously, inferRemoteSize() had a fixed implementation that fetched the entire image to determine its dimensions.
    With this new helper function that extends inferRemoteSize(), you can now override or extend how remote image metadata is retrieved.

    This enables use cases such as:

    • Caching: Storing image dimensions in a database or local cache to avoid redundant network requests.
    • Provider APIs: Using a specific image provider's API (like Cloudinary or Vercel) to get dimensions without downloading the file.

    For example, you can add a simple cache layer to your existing image service:

    const cache = new Map();

const myService = {
  ...baseService,
  async getRemoteSize(url, imageConfig) {
    if (cache.has(url)) return cache.get(url);

    const result = await baseService.getRemoteSize(url, imageConfig);
    cache.set(url, result);
    return result;
  },
};

    See the Image Services API reference documentation for more information.

  • #​15077 a164c77 Thanks @​matthewp! - Updates the Integration API to add setPrerenderer() to the astro:build:start hook, allowing adapters to provide custom prerendering logic.

    The new API accepts either an AstroPrerenderer object directly, or a factory function that receives the default prerenderer:

    'astro:build:start': ({ setPrerenderer }) => {
  setPrerenderer((defaultPrerenderer) => ({
    name: 'my-prerenderer',
    async setup() {
      // Optional: called once before prerendering starts
    },
    async getStaticPaths() {
      // Returns array of { pathname: string, route: RouteData }
      return defaultPrerenderer.getStaticPaths();
    },
    async render(request, { routeData }) {
      // request: Request
      // routeData: RouteData
      // Returns: Response
    },
    async teardown() {
      // Optional: called after all pages are prerendered
    }
  }));
}

    Also adds the astro:static-paths virtual module, which exports a StaticPaths class for adapters to collect all prerenderable paths from within their target runtime. This is useful when implementing a custom prerenderer that runs in a non-Node environment:

    // In your adapter's request handler (running in target runtime)
import { App } from 'astro/app';
import { StaticPaths } from 'astro:static-paths';

export function createApp(manifest) {
  const app = new App(manifest);

  return {
    async fetch(request) {
      const { pathname } = new URL(request.url);

      // Expose endpoint for prerenderer to get static paths
      if (pathname === '/__astro_static_paths') {
        const staticPaths = new StaticPaths(app);
        const paths = await staticPaths.getAll();
        return new Response(JSON.stringify({ paths }));
      }

      // Normal request handling
      return app.render(request);
    },
  };
}

    See the adapter reference for more details on implementing a custom prerenderer.

  • #​15345 840fbf9 Thanks @​matthewp! - Adds a new emitClientAsset function to astro/assets/utils for integration authors. This function allows emitting assets that will be moved to the client directory during SSR builds, useful for assets referenced in server-rendered content that need to be available on the client.

    import { emitClientAsset } from 'astro/assets/utils';

// Inside a Vite plugin's transform or load hook
const handle = emitClientAsset(this, {
  type: 'asset',
  name: 'my-image.png',
  source: imageBuffer,
});

  • #​15460 ee7e53f Thanks @​florian-lefebvre! - Updates the Adapter API to allow providing a serverEntrypoint when using entryType: 'self'

    Astro 6 introduced a new powerful yet simple Adapter API for defining custom server entrypoints. You can now call setAdapter() with the entryType: 'self' option and specify your custom serverEntrypoint:

    export function myAdapter() {
  return {
    name: 'my-adapter',
    hooks: {
      'astro:config:done': ({ setAdapter }) => {
        setAdapter({
          name: 'my-adapter',
          entryType: 'self',
          serverEntrypoint: 'my-adapter/server.js',
          supportedAstroFeatures: {
            // ...
          },
        });
      },
    },
  };
}

    If you need further customization at the Vite level, you can omit serverEntrypoint and instead specify your custom server entrypoint with vite.build.rollupOptions.input.

  • #​15781 2de969d Thanks @​ematipico! - Adds a new clientAddress option to the createContext() function

    Providing this value gives adapter and middleware authors explicit control over the client IP address. When not provided, accessing clientAddress throws an error consistent with other contexts where it is not set by the adapter.

    Additionally, both of the official Netlify and Vercel adapters have been updated to provide this information in their edge middleware.

    import { createContext } from 'astro/middleware';

createContext({
  clientAddress: context.headers.get('x-real-ip'),
});

  • #​15258 d339a18 Thanks @​ematipico! - Stabilizes the adapter feature experimentalStatiHeaders. If you were using this feature in any of the supported adapters, you'll need to change the name of the flag:

    export default defineConfig({
  adapter: netlify({
-    experimentalStaticHeaders: true
+    staticHeaders: true
  })
})

  • #​15535 dfe2e22 Thanks @​florian-lefebvre! - Exports new createRequest() and writeResponse() utilities from astro/app/node

    To replace the deprecated NodeApp.createRequest() and NodeApp.writeResponse() methods, the astro/app/node module now exposes new createRequest() and writeResponse() utilities. These can be used to convert a NodeJS IncomingMessage into a web-standard Request and stream a web-standard Response into a NodeJS ServerResponse:

    import { createApp } from 'astro/app/entrypoint';
import { createRequest, writeResponse } from 'astro/app/node';
import { createServer } from 'node:http';

const app = createApp();

const server = createServer(async (req, res) => {
  const request = createRequest(req);
  const response = await app.render(request);
  await writeResponse(response, res);
});

  • #​15755 f9ee868 Thanks @​matthewp! - Adds a new security.serverIslandBodySizeLimit configuration option

    Server island POST endpoints now enforce a body size limit, similar to the existing security.actionBodySizeLimit for Actions. The new option defaults to 1048576 (1 MB) and can be configured independently.

    Requests exceeding the limit are rejected with a 413 response. You can customize the limit in your Astro config:

    export default defineConfig({
  security: {
    serverIslandBodySizeLimit: 2097152, // 2 MB
  },
});

  • #​15529 a509941 Thanks @​florian-lefebvre! - Adds a new build-in font provider npm to access fonts installed as NPM packages

    You can now add web fonts specified in your package.json through Astro's type-safe Fonts API. The npm font provider allows you to add fonts either from locally installed packages in node_modules or from a CDN.

    Set fontProviders.npm() as your fonts provider along with the required name and cssVariable values, and add options as needed:

    import { defineConfig, fontProviders } from 'astro/config';

export default defineConfig({
  experimental: {
    fonts: [
      {
        name: 'Roboto',
        provider: fontProviders.npm(),
        cssVariable: '--font-roboto',
      },
    ],
  },
});

    See the NPM font provider reference documentation for more details.

  • #​15471 32b4302 Thanks @​ematipico! - Adds a new experimental flag queuedRendering to enable a queue-based rendering engine

    The new engine is based on a two-pass process, where the first pass
    traverses the tree of components, emits an ordered queue, and then the queue is rendered.

    The new engine does not use recursion, and comes with two customizable options.

    Early benchmarks showed significant speed improvements and memory efficiency in big projects.

Queue-rendered based

The new engine can be enabled in your Astro config with experimental.queuedRendering.enabled set to true, and can be further customized with additional sub-features.

// astro.config.mjs
export default defineConfig({
  experimental: {
    queuedRendering: {
      enabled: true,
    },
  },
});
Pooling

With the new engine enabled, you now have the option to have a pool of nodes that can be saved and reused across page rendering. Node pooling has no effect when rendering pages on demand (SSR) because these rendering requests don't share memory. However, it can be very useful for performance when building static pages.

// astro.config.mjs
export default defineConfig({
  experimental: {
    queuedRendering: {
      enabled: true,
      poolSize: 2000, // store up to 2k nodes to be reused across renderers
    },
  },
});
Content caching

The new engine additionally unlocks a new contentCache option. This allows you to cache values of nodes during the rendering phase. This is currently a boolean feature with no further customization (e.g. size of cache) that uses sensible defaults for most large content collections:

When disabled, the pool engine won't cache strings, but only types.

// astro.config.mjs
export default defineConfig({
  experimental: {
    queuedRendering: {
      enabled: true,
      contentCache: true, // enable re-use of node values
    },
  },
});

For more information on enabling and using this feature in your project, see the experimental queued rendering docs for more details.

  • #​14888 4cd3fe4 Thanks @​OliverSpeir! - Updates astro add cloudflare to better setup types, by adding ./worker-configuration.d.ts to tsconfig includes and a generate-types script to package.json

  • #​15646 0dd9d00 Thanks @​delucis! - Removes redundant fetchpriority attributes from the output of Astro’s <Image> component

    Previously, Astro would always include fetchpriority="auto" on images not using the priority attribute.
    However, this is the default value, so specifying it is redundant. This change omits the attribute by default.

  • #​15291 89b6cdd Thanks @​florian-lefebvre! - Removes the experimental.fonts flag and replaces it with a new configuration option fonts - (v6 upgrade guidance)

  • #​15495 5b99e90 Thanks @​leekeh! - Adds a new middlewareMode adapter feature to replace the previous edgeMiddleware option.

    This feature only impacts adapter authors. If your adapter supports edgeMiddleware, you should upgrade to the new middlewareMode option to specify the middleware mode for your adapter as soon as possible. The edgeMiddleware feature is deprecated and will be removed in a future major release.

    export default function createIntegration() {
  return {
    name: '@&#8203;example/my-adapter',
    hooks: {
      'astro:config:done': ({ setAdapter }) => {
        setAdapter({
          name: '@&#8203;example/my-adapter',
          serverEntrypoint: '@&#8203;example/my-adapter/server.js',
          adapterFeatures: {
-            edgeMiddleware: true
+            middlewareMode: 'edge'
          }
        });
      },
    },
  };
}

  • #​15694 66449c9 Thanks @​matthewp! - Adds preserveBuildClientDir option to adapter features

    Adapters can now opt in to preserving the client/server directory structure for static builds by setting preserveBuildClientDir: true in their adapter features. When enabled, static builds will output files to build.client instead of directly to outDir.

    This is useful for adapters that require a consistent directory structure regardless of the build output type, such as deploying to platforms with specific file organization requirements.

    // my-adapter/index.js
export default function myAdapter() {
  return {
    name: 'my-adapter',
    hooks: {
      'astro:config:done': ({ setAdapter }) => {
        setAdapter({
          name: 'my-adapter',
          adapterFeatures: {
            buildOutput: 'static',
            preserveBuildClientDir: true,
          },
        });
      },
    },
  };
}

  • #​15332 7c55f80 Thanks @​matthewp! - Adds a fileURL option to renderMarkdown in content loaders, enabling resolution of relative image paths. When provided, relative image paths in markdown will be resolved relative to the specified file URL and included in metadata.localImagePaths.

    const loader = {
  name: 'my-loader',
  load: async ({ store, renderMarkdown }) => {
    const content = `
# My Post

![Local image](./image.png)
`;
    // Provide a fileURL to resolve relative image paths
    const fileURL = new URL('./posts/my-post.md', import.meta.url);
    const rendered = await renderMarkdown(content, { fileURL });
    // rendered.metadata.localImagePaths now contains the resolved image path
  },
};

  • #​15407 aedbbd8 Thanks @​ematipico! - Adds support for responsive images when security.csp is enabled, out of the box.

    Astro's implementation of responsive image styles has been updated to be compatible with a configured Content Security Policy.

    Instead of, injecting style elements at runtime, Astro will now generate your styles at build time using a combination of class="" and data-* attributes. This means that your processed styles are loaded and hashed out of the box by Astro.

    If you were previously choosing between Astro's CSP feature and including responsive images on your site, you may now use them together.

  • #​15543 d43841d Thanks @​Princesseuh! - Adds a new experimental.rustCompiler flag to opt into the experimental Rust-based Astro compiler

    This experimental compiler is faster, provides better error messages, and generally has better support for modern JavaScript, TypeScript, and CSS features.

    After enabling in your Astro config, the @astrojs/compiler-rs package must also be installed into your project separately:

    import { defineConfig } from 'astro/config';

export default defineConfig({
  experimental: {
    rustCompiler: true,
  },
});

    This new compiler is still in early development and may exhibit some differences compared to the existing Go-based compiler. Notably, this compiler is generally more strict in regard to invalid HTML syntax and may throw errors in cases where the Go-based compiler would have been more lenient. For example, unclosed tags (e.g. <p>My paragraph) will now result in errors.

    For more information about using this experimental feature in your project, especially regarding expected differences and limitations, please see the experimental Rust compiler reference docs. To give feedback on the compiler, or to keep up with its development, see the RFC for a new compiler for Astro for more information and discussion.

  • #​15349 a257c4c Thanks @​ascorbic! - Passes collection name to live content loaders

    Live content collection loaders now receive the collection name as part of their parameters. This is helpful for loaders that manage multiple collections or need to differentiate behavior based on the collection being accessed.

    export function storeLoader({ field, key }) {
  return {
    name: 'store-loader',
    loadCollection: async ({ filter, collection }) => {
      // ...
    },
    loadEntry: async ({ filter, collection }) => {
      // ...
    },
  };
}

  • #​15006 f361730 Thanks @​florian-lefebvre! - Adds new session driver object shape

    For greater flexibility and improved consistency with other Astro code, session drivers are now specified as an object:

    -import { defineConfig } from 'astro/config'
+import { defineConfig, sessionDrivers } from 'astro/config'

export default defineConfig({
  session: {
-    driver: 'redis',
-    options: {
-      url: process.env.REDIS_URL
-    },
+    driver: sessionDrivers.redis({
+      url: process.env.REDIS_URL
+    }),
  }
})

    Specifying the session driver as a string has been deprecated, but will continue to work until this feature is removed completely in a future major version. The object shape is the current recommended and documented way to configure a session driver.

  • #​15291 89b6cdd Thanks @​florian-lefebvre! - Adds a new Fonts API to provide first-party support for adding custom fonts in Astro.

    This feature allows you to use fonts from both your file system and several built-in supported providers (e.g. Google, Fontsource, Bunny) through a unified API. Keep your site performant thanks to sensible defaults and automatic optimizations including preloading and fallback font generation.

    To enable this feature, configure fonts with one or more fonts:

    import { defineConfig, fontProviders } from 'astro/config';

export default defineConfig({
  fonts: [
    {
      provider: fontProviders.fontsource(),
      name: 'Roboto',
      cssVariable: '--font-roboto',
    },
  ],
});

    Import and include the <Font /> component with the required cssVariable property in the head of your page, usually in a dedicated Head.astro component or in a layout component directly:

    ---
// src/layouts/Layout.astro
import { Font } from 'astro:assets';
---

<html>
  <head>
    <Font cssVariable="--font-roboto" preload />
  </head>
  <body>
    <slot />
  </body>
</html>

    In any page rendered with that layout, including the layout component itself, you can now define styles with your font's cssVariable to apply your custom font.

    In the following example, the <h1> heading will have the custom font applied, while the paragraph <p> will not.

    ---
// src/pages/example.astro
import Layout from '../layouts/Layout.astro';
---

<Layout>
  <h1>In a galaxy far, far away...</h1>

  <p>Custom fonts make my headings much cooler!</p>

  <style>
    h1 {
      font-family: var('--font-roboto');
    }
  </style>
</Layout>

  • #​14550 9c282b5 Thanks @​ascorbic! - Adds support for live content collections

    Live content collections are a new type of content collection that fetch their data at runtime rather than build time. This allows you to access frequently updated data from CMSs, APIs, databases, or other sources using a unified API, without needing to rebuild your site when the data changes.

Live collections vs build-time collections

In Astro 5.0, the content layer API added support for adding diverse content sources to content collections. You can create loaders that fetch data from any source at build time, and then access it inside a page via getEntry() and getCollection(). The data is cached between builds, giving fast access and updates.

However, there was no method for updating the data store between builds, meaning any updates to the data needed a full site deploy, even if the pages are rendered on demand. This meant that content collections were not suitable for pages that update frequently. Instead, these pages tended to access the APIs directly in the frontmatter. This worked, but it led to a lot of boilerplate, and meant users didn't benefit from the simple, unified API that content loaders offer. In most cases, users tended to individually create loader libraries shared between pages.

Live content collections (introduced experimentally in Astro 5.10) solve this problem by allowing you to create loaders that fetch data at runtime, rather than build time. This means that the data is always up-to-date, without needing to rebuild the site.

How to use

To use live collections, create a new src/live.config.ts file (alongside your src/content.config.ts if you have one) to define your live collections with a live content loader using the new defineLiveCollection() function from the astro:content module:

import { defineLiveCollection } from 'astro:content';
import { storeLoader } from '@&#8203;mystore/astro-loader';

const products = defineLiveCollection({
  loader: storeLoader({
    apiKey: process.env.STORE_API_KEY,
    endpoint: 'https://api.mystore.com/v1',
  }),
});

export const collections = { products };

You can then use the getLiveCollection() and getLiveEntry() functions to access your live data, along with error handling (since anything can happen when requesting live data!):

---
import { getLiveCollection, getLiveEntry, render } from 'astro:content';
// Get all products
const { entries: allProducts, error } = await getLiveCollection('products');
if (error) {
  // Handle error appropriately
  console.error(error.message);
}

// Get products with a filter (if supported by your loader)
const { entries: electronics } = await getLiveCollection('products', { category: 'electronics' });

// Get a single product by ID (string syntax)
const { entry: product, error: productError } = await getLiveEntry('products', Astro.params.id);
if (productError) {
  return Astro.redirect('/404');
}

// Get a single product with a custom query (if supported by your loader) using a filter object
const { entry: productBySlug } = await getLiveEntry('products', { slug: Astro.params.slug });
const { Content } = await render(product);
---

<h1>{product.data.title}</h1>
<Content />
Upgrading from experimental live collections

If you were using the experimental feature, you must remove the experimental.liveContentCollections flag from your astro.config.* file:

 export default defineConfig({
   // ...
-  experimental: {
-    liveContentCollections: true,
-  },
 });

No other changes to your project code are required as long as you have been keeping up with Astro 5.x patch releases, which contained breaking changes to this experimental feature. If you experience problems with your live collections after upgrading to Astro v6 and removing this flag, please review the Astro CHANGELOG from 5.10.2 onwards for any potential updates you might have missed, or follow the current v6 documentation for live collections.

  • #​15548 5b8f573 Thanks @​florian-lefebvre! - Adds a new optional embeddedLangs prop to the <Code /> component to support languages beyond the primary lang

  • #​14826 170f64e Thanks @​florian-lefebvre! - Adds an option prerenderConflictBehavior to configure the behavior of conflicting prerendered routes

    By default, Astro warns you during the build about any conflicts between multiple dynamic routes that can result in the same output path. For example /blog/[slug] and /blog/[...all] both could try to prerender the /blog/post-1 path. In such cases, Astro renders only the highest priority route for the conflicting path. This allows your site to build successfully, although you may discover that some pages are rendered by unexpected routes.

    With the new prerenderConflictBehavior configuration option, you can now configure this further:

    • prerenderConflictBehavior: 'error' fails the build
    • prerenderConflictBehavior: 'warn' (default) logs a warning and the highest-priority route wins
    • prerenderConflictBehavior: 'ignore' silently picks the highest-priority route when conflicts occur
    import { defineConfig } from 'astro/config';

export default defineConfig({
+    prerenderConflictBehavior: 'error',
});

  • #​14946 95c40f7 Thanks @​ematipico! - Removes the experimental.csp flag and replaces it with a new configuration option security.csp - (v6 upgrade guidance)

  • #​15579 08437d5 Thanks @​ascorbic! - Adds two new experimental flags for a Route Caching API and further configuration-level Route Rules for controlling SSR response caching.

    Route caching gives you a platform-agnostic way to cache server-rendered responses, based on web standard cache headers. You set caching directives in your routes using Astro.cache (in .astro pages) or context.cache (in API routes and middleware), and Astro translates them into the appropriate headers or runtime behavior depending on your adapter. You can also define cache rules for routes declaratively in your config using experimental.routeRules, without modifying route code.

    This feature requires on-demand rendering. Prerendered pages are already static and do not use route caching.

Getting started

Enable the feature by configuring experimental.cache with a cache provider in your Astro config:

// astro.config.mjs
import { defineConfig } from 'astro/config';
import node from '@&#8203;astrojs/node';
import { memoryCache } from 'astro/config';

export default defineConfig({
  adapter: node({ mode: 'standalone' }),
  experimental: {
    cache: {
      provider: memoryCache(),
    },
  },
});
Using Astro.cache and context.cache

In .astro pages, use Astro.cache.set() to control caching:

---
// src/pages/index.astro
Astro.cache.set({
  maxAge: 120, // Cache for 2 minutes
  swr: 60, // Serve stale for 1 minute while revalidating
  tags: ['home'], // Tag for targeted invalidation
});
---

<html><body>Cached page</body></html>

In API routes and middleware, use context.cache:

// src/pages/api/data.ts
export function GET(context) {
  context.cache.set({
    maxAge: 300,
    tags: ['api', 'data'],
  });
  return Response.json({ ok: true });
}
Cache options

cache.set() accepts the following options:

  • maxAge (number): Time in seconds the response is considered fresh.
  • swr (number): Stale-while-revalidate window in seconds. During this window, stale content is served while a fresh response is generated in the background.
  • tags (string[]): Cache tags for targeted invalidation. Tags accumulate across multiple set() calls within a request.
  • lastModified (Date): When multiple set() calls provide lastModified, the most recent date wins.
  • etag (string): Entity tag for conditional requests.

Call cache.set(false) to explicitly opt out of caching for a request.

Multiple calls to cache.set() within a single request are merged: scalar values use last-write-wins, lastModified uses most-recent-wins, and tags accumulate.

Invalidation

Purge cached entries by tag or path using cache.invalidate():

// Invalidate all entries tagged 'data'
await context.cache.invalidate({ tags: ['data'] });

// Invalidate a specific path
await context.cache.invalidate({ path: '/api/data' });
Config-level route rules

Use experimental.routeRules to set default cache options for routes without modifying route code. Supports Nitro-style shortcuts for ergonomic configuration:

import { memoryCache } from 'astro/config';

export default defineConfig({
  experimental: {
    cache: {
      provider: memoryCache(),
    },
    routeRules: {
      // Shortcut form (Nitro-style)
      '/api/*': { swr: 600 },

      // Full form with nested cache
      '/products/*': { cache: { maxAge: 3600, tags: ['products'] } },
    },
  },
});

Route patterns support static paths, dynamic parameters ([slug]), and rest parameters ([...path]). Per-route cache.set() calls merge with (and can override) the config-level defaults.

You can also read the current cache state via cache.options:

const { maxAge, swr, tags } = context.cache.options;
Cache providers

Cache behavior is determined by the configured cache provider. There are two types:

  • CDN providers set response headers (e.g. CDN-Cache-Control, Cache-Tag) and let the CDN handle caching. Astro strips these headers before sending the response to the client.
  • Runtime providers implement onRequest() to intercept and cache responses in-process, adding an X-Astro-Cache header (HIT/MISS/STALE) for observability.
Built-in memory cache provider

Astro includes a built-in, in-memory LRU runtime cache provider. Import memoryCache from astro/config to configure it.

Features:

  • In-memory LRU cache with configurable max entries (default: 1000)
  • Stale-while-revalidate support
  • Tag-based and path-based invalidation
  • X-Astro-Cache response header: HIT, MISS, or STALE
  • Query parameter sorting for better hit rates (?b=2&a=1 and ?a=1&b=2 hit the same entry)
  • Common tracking parameters (utm_*, fbclid, gclid, etc.) excluded from cache keys by default
  • Vary header support — responses that set Vary automatically get separate cache entries per variant
  • Configurable query parameter filtering via query.exclude (glob patterns) and query.include (allowlist)

For more information on enabling and using this feature in your project, see the Experimental Route Caching docs.
For a complete overview and to give feedback on this experimental API, see the Route Caching RFC.

  • #​15483 7be3308 Thanks @​florian-lefebvre! - Adds streaming option to the createApp() function in the Adapter API, mirroring the same functionality available when creating a new App instance

    An adapter's createApp() function now accepts streaming (defaults to true) as an option. HTML streaming breaks a document into chunks to send over the network and render on the page in order. This normally results in visitors seeing your HTML as fast as possible but factors such as network conditions and waiting for data fetches can block page rendering.

    HTML streaming helps with performance and generally provides a better visitor experience. In most cases, disabling streaming is not recommended.

    However, when you need to disable HTML streaming (e.g. your host only supports non-streamed HTML caching at the CDN level), you can opt out of the default behavior by passing streaming: false to createApp():

    import { createApp } from 'astro/app/entrypoint';

const app = createApp({ streaming: false });

    See more about the createApp() function in the Adapter API reference.

Patch Changes

  • #​15423 c5ea720 Thanks @​matthewp! - Improves error message when a dynamic redirect destination does not match any existing route.

    Previously, configuring a redirect like /categories/[category] → /categories/[category]/1 in static output mode would fail with a misleading "getStaticPaths required" error. Now, Astro detects this early and provides a clear error explaining that the destination does not match any existing route.

  • #​15167 4fca170 Thanks @​HiDeoo! - Fixes an issue where CSS from unused components, when using content collections, could be incorrectly included between page navigations in development mode.

  • #​15565 30cd6db Thanks @​ematipico! - Fixes an issue where the use of the Astro internal logger couldn't work with Cloudflare Vite plugin.

  • #​15508 2c6484a Thanks @​KTibow! - Fixes behavior when shortcuts are used before server is ready

  • #​15125 6feb0d7 Thanks @​florian-lefebvre! - Improves JSDoc annotations for AstroGlobal, AstroSharedContext and APIContext types

  • #​15712 7ac43c7 Thanks @​florian-lefebvre! - Improves astro info by supporting more operating systems when copying the information to the clipboard.

  • #​15054 22db567 Thanks @​matthewp! - Improves zod union type error messages to show expected vs received types instead of generic "Invalid input"

  • #​15064 caf5621 Thanks @​ascorbic! - Fixes a bug that caused incorrect warnings of duplicate entries to be logged by the glob loader when editing a file

  • #​15801 01db4f3 Thanks @​ascorbic! - Improves the experience of working with experimental route caching in dev mode by replacing some errors with silent no-ops, avoiding the need to write conditional logic to handle different modes

    Adds a cache.enabled property to CacheLike so libraries can check whether caching is active without try/catch.

  • #​15562 e14a51d Thanks @​florian-lefebvre! - Removes types for the astro:ssr-manifest module, which was removed

  • #​15542 9760404 Thanks @​rururux! - Improves rendering by preserving hidden="until-found" value in attributes

  • #​15044 7cac71b Thanks @​florian-lefebvre! - Removes an exposed internal API of the preview server

  • #​15573 d789452 Thanks @​matthewp! - Clear the route cache on content changes so slug pages reflect updated data during dev.

  • #​15308 89cbcfa Thanks @​matthewp! - Fixes styles missing in dev for prerendered pages when using Cloudflare adapter

  • #​15435 957b9fe Thanks @​rururux! - Improves compatibility of the built-in image endpoint with runtimes that don't support CJS dependencies correctly

  • #​15640 4c1a801 Thanks @​ematipico! - Reverts the support of Shiki with CSP. Unfortunately, after exhaustive tests, the highlighter can't be supported to cover all cases.

    Adds a warning when both Content Security Policy (CSP) and Shiki syntax highlighting are enabled, as they are incompatible due to Shiki's use of inline styles

  • #​15415 cc3c46c Thanks @​ematipico! - Fixes an issue where CSP headers were incorrectly injected in the development server.

  • #​15412 c546563 Thanks @​florian-lefebvre! - Improves the AstroAdapter type and how legacy adapters are handled

  • #​15322 18e0980 Thanks @​matthewp! - Prevents missing CSS when using both SSR and prerendered routes

  • #​15760 f49a27f Thanks @​ematipico! - Fixed an issue where queued rendering wasn't correctly re-using the saved nodes.

  • #​15277 cb99214 Thanks @​ematipico! - Fixes an issue where the function createShikiHighlighter would always create a new Shiki highlighter instance. Now the function returns a cached version of the highlighter based on the Shiki options. This should improve the performance for sites that heavily rely on Shiki and code in their pages.

  • #​15394 5520f89 Thanks @​florian-lefebvre! - Fixes a case where using the Fonts API with netlify dev wouldn't work because of query parameters

  • #​15605 f6473fd Thanks @​ascorbic! - Improves .astro component SSR rendering performance by up to 2x.

    This includes several optimizations to the way that Astro generates and renders components on the server. These are mostly micro-optimizations, but they add up to a significant improvement in performance. Most pages will benefit, but pages with many components will see the biggest improvement, as will pages with lots of strings (e.g. text-heavy pages with lots of HTML elements).

  • #​15721 e6e146c Thanks @​matthewp! - Fixes action route handling to return 404 for requests to prototype method names like constructor or toString used as action paths

  • #​15497 a93c81d Thanks @​matthewp! - Fix dev reloads for content collection Markdown updates under Vite 7.

  • #​15780 e0ac125 Thanks @​ematipico! - Prevents vite.envPrefix misconfiguration from exposing access: "secret" environment variables in client-side bundles. Astro now throws a clear error at startup if any vite.envPrefix entry matches a variable declared with access: "secret" in env.schema.

    For example, the following configuration will throw an error for API_SECRET because it's defined as secret its name matches ['PUBLIC_', 'API_'] defined in env.schema:

    // astro.config.mjs
import { defineConfig } from 'astro/config';

export default defineConfig({
  env: {
    schema: {
      API_SECRET: envField.string({ context: 'server', access: 'secret', optional: true }),
      API_URL: envField.string({ context: 'server', access: 'public', optional: true }),
    },
  },
  vite: {
    envPrefix: ['PUBLIC_', 'API_'],
  },
});

  • #​15514 999a7dd Thanks @​veeceey! - Fixes font flash (FOUT) during ClientRouter navigation by preserving inline <style> elements and font preload links in the head during page transitions.

    Previously, @font-face declarations from the <Font> component were removed and re-inserted on every client-side navigation, causing the browser to re-evaluate them.

  • #​15560 170ed89 Thanks @​z0mt3c! - Fix X-Forwarded-Proto validation when allowedDomains includes both protocol and hostname fields. The protocol check no longer fails due to hostname mismatch against the hardcoded test URL.

  • #​15704 862d77b Thanks @​umutkeltek! - Fixes i18n fallback middleware intercepting non-404 responses

    The fallback middleware was triggering for all responses with status >= 300, including legitimate 3xx redirects, 403 forbidden, and 5xx server errors. This broke auth flows and form submissions on localized server routes. The fallback now correctly only triggers for 404 (page not found) responses.

  • #​15661 7150a2e Thanks @​ematipico! - Fixes a build error when generating projects with 100k+ static routes.

  • #​15580 a92333c Thanks @​ematipico! - Fixes a build error when generating projects with a large number of static routes

  • #​15176 9265546 Thanks @​matthewp! - Fixes hydration for framework components inside MDX when using Astro.slots.render()

    Previously, when multiple framework components with client:* directives were passed as named slots to an Astro component in MDX, only the first slot would hydrate correctly. Subsequent slots would render their HTML but fail to include the necessary hydration scripts.

  • #​15506 074901f Thanks @​ascorbic! - Fixes a race condition where concurrent requests to dynamic routes in the dev server could produce incorrect params.

  • #​15444 10b0422 Thanks @​AhmadYasser1! - Fixes Astro.rewrite returning 404 when rewriting to a URL with non-ASCII characters

    When rewriting to a path containing non-ASCII characters (e.g., /redirected/héllo), the route lookup compared encoded distURL hrefs against decoded pathnames, causing the comparison to always fail and resulting in a 404. This fix compares against the encoded pathname instead.

  • #​15728 12ca621 Thanks @​SvetimFM! - Improves internal state retention for persisted elements during view transitions, especially avoiding WebGL context loss in Safari and resets of CSS transitions and iframes in modern Chromium and Firefox browsers

  • #​15279 8983f17 Thanks @​ematipico! - Fixes an issue where the dev server would serve files like /README.md from the project root when they shouldn't be accessible. A new route guard middleware now blocks direct URL access to files that exist outside of srcDir and publicDir, returning a 404 instead.

  • #​15703 829182b Thanks @​matthewp! - Fixes server islands returning a 500 error in dev mode for adapters that do not set adapterFeatures.buildOutput (e.g. @astrojs/netlify)

  • #​15749 573d188 Thanks @​ascorbic! - Fixes a bug that caused session.regenerate() to silently lose session data

    Previously, regenerated session data was not saved under the new session ID unless set() was also called.

  • #​15549 be1c87e Thanks @​0xRozier! - Fixes an issue where original (unoptimized) images from prerendered pages could be kept in the build output during SSR builds.

  • #​15454 b47a4e1 Thanks @​Fryuni! - Fixes a race condition in the content layer which could result in dropped content collection entries.

  • #​15685 1a323e5 Thanks @​jcayzac! - Fix regression where SVG images in content collection image() fields could not be rendered as inline components. This behavior is now restored while preserving the TLA deadlock fix.

  • #​15603 5bc2b2c Thanks @​0xRozier! - Fixes a deadlock that occurred when using SVG images in content collections

  • #​15385 9e16d63 Thanks @​matthewp! - Fixes content layer loaders that use dynamic imports

    Content collection loaders can now use await import() and import.meta.glob() to dynamically import modules during build. Previously, these would fail with "Vite module runner has been closed."

  • #​15565 30cd6db Thanks @​ematipico! - Fixes an issue where the use of the Code component would result in an unexpected error.

  • #​15125 6feb0d7 Thanks @​florian-lefebvre! - Fixes remote images Etag header handling by disabling internal cache

  • #​15317 7e1e35a Thanks @​matthewp! - Fixes ?raw imports failing when used in both SSR and prerendered routes

  • #​15809 94b4a46 Thanks @​Princesseuh! - Fixes fit defaults not being applied unless layout was also specified

  • #​15563 e959698 Thanks @​ematipico! - Fixes an issue where warnings would be logged during the build using one of the official adapters

  • #​15121 06261e0 Thanks @​ematipico! - Fixes a bug where the Astro, with the Cloudflare integration, couldn't correctly serve certain routes in the development server.

  • #​15585 98ea30c Thanks @​matthewp! - Add a default body size limit for server actions to prevent oversized requests from exhausting memory.

  • #​15264 11efb05 Thanks @​florian-lefebvre! - Lower the Node version requirement to allow running on Stackblitz until it supports v22

  • #​15778 4ebc1e3 Thanks @​ematipico! - Fixes an issue where the computed clientAddress was incorrect in cases of a Request header with multiple values. The clientAddress is now also validated to contain only characters valid in IP addresses, rejecting injection payloads.

  • #​15565 30cd6db Thanks @​ematipico! - Fixes an issue where the new Astro v6 development server didn't log anything when navigating the pages.

  • #​15024 22c48ba Thanks @​florian-lefebvre! - Fixes a case where JSON schema generation would fail for unrepresentable types

  • #​15669 d5a888b Thanks @​florian-lefebvre! - Removes the cssesc dependency

    This CommonJS dependency could sometimes cause errors because Astro is ESM-only. It is now replaced with a built-in ESM-friendly implementation.

  • #​15740 c5016fc Thanks @​matthewp! - Removes an escape hatch that skipped attribute escaping for URL values containing &, ensuring all dynamic attribute values are consistently escaped

  • #​15756 b6c64d1 Thanks @​matthewp! - Hardens the dev server by validating Sec-Fetch metadata headers to restrict cross-origin subresource requests

  • #​15744 fabb710 Thanks @​matthewp! - Fixes cookie handling during error page rendering to ensure cookies set by middleware are consistently included in the response

  • #​15776 e9a9cc6 Thanks @​matthewp! - Hardens error page response merging to ensure framing headers from the original response are not carried over to the rendered error page

  • #​15759 39ff2a5 Thanks @​matthewp! - Adds a new bodySizeLimit option to the @astrojs/node adapter

    You can now configure a maximum allowed request body size for your Node.js standalone server. The default limit is 1 GB. Set the value in bytes, or pass 0 to disable the limit entirely:

    import node from '@&#8203;astrojs/node';
import { defineConfig } from 'astro/config';

export default defineConfig({
  adapter: node({
    mode: 'standalone',
    bodySizeLimit: 1024 * 1024 * 100, // 100 MB
  }),
});

  • #​15777 02e24d9 Thanks @​matthewp! - Fixes CSRF origin check mismatch by passing the actual server listening port to createRequest, ensuring the constructed URL origin includes the correct port (e.g., http://localhost:4321 instead of http://localhost). Also restricts X-Forwarded-Proto to only be trusted when allowedDomains is configured.

  • #​15742 9d9699c Thanks @​matthewp! - Hardens clientAddress resolution to respect security.allowedDomains for X-Forwarded-For, consistent with the existing handling of X-Forwarded-Host, X-Forwarded-Proto, and X-Forwarded-Port. The X-Forwarded-For header is now only used to determine Astro.clientAddress when the request's host has been validated against an allowedDomains entry. Without a matching domain, clientAddress falls back to the socket's remote address.

  • #​15768 6328f1a Thanks @​matthewp! - Hardens internal cookie parsing to use a null-prototype object consistently for the fallback path, aligning with how the cookie library handles parsed values

  • #​15125 6feb0d7 Thanks @​florian-lefebvre! - Fixes images not working in development when using setups with port forwarding

  • #​15811 2ba0db5 Thanks @​ematipico! - Fixes integration-injected scripts (e.g. Alpine.js via injectScript()) not being loaded in the dev server when using non-runnable environment adapters like @astrojs/cloudflare.

  • #​15208 8dbdd8e Thanks @​matthewp! - Makes session.driver optional in config schema, allowing adapters to provide default drivers

    Adapters like Cloudflare, Netlify, and Node provide default session drivers, so users can now configure session options (like ttl) without explicitly specifying a driver.

  • #​15260 abca1eb Thanks @​ematipico! - Fixes an issue where adding new pages weren't correctly shown when using the development server.

  • #​15591 1ed07bf Thanks @​renovate! - Upgrades devalue to v5.6.3

  • #​15137 2f70bf1 Thanks @​matthewp! - Adds legacy.collectionsBackwardsCompat flag that restores v5 backwards compatibility behavior for legacy content collections - (v6 upgrade guidance)

    When enabled, this flag allows:

    • Collections defined without loaders (automatically get glob loader)
    • Collections with type: 'content' or type: 'data'
    • Config files located at src/content/config.ts (legacy location)
    • Legacy entry API: entry.slug and entry.render() methods
    • Path-based entry IDs instead of slug-based IDs
    // astro.config.mjs
export default defineConfig({
  legacy: {
    collectionsBackwardsCompat: true,
  },
});

    This is a temporary migration helper for v6 upgrades. Migrate collections to the Content Layer API, then disable this flag.

  • #​15125 6feb0d7 Thanks @​florian-lefebvre! - BREAKING CHANGE to the experimental Fonts API only

    Changes the font format downloaded by default when using the experimental Fonts API. Additionally, adds a new formats configuration option to specify which font formats to download.

    Previously, Astro was opinionated about which font sources would be kept for usage, mainly keeping woff2 and woff files.

    You can now specify what font formats should be downloaded (if available). Only woff2 files are downloaded by default.

What should I do?

If you were previously relying on Astro downloading the woff format, you will now need to specify this explicitly with the new formats configuration option. Additionally, you may also specify any additional file formats to download if available:

// astro.config.mjs
import { defineConfig, fontProviders } from 'astro/config'

export default defineConfig({
    experimental: {
        fonts: [{
            name: 'Roboto',
            cssVariable: '--font-roboto',
            provider: fontProviders.google(),
+            formats: ['woff2', 'woff', 'otf']
        }]
    }
})

However, there can be security implications with prefetching from other hosts, and often more customization was required to do this safely. This has now been removed as a built-in option so that you can implement your own secure solution as needed and appropriate for your project via middleware. ##### What should I do? If you were previously using this feature, you must remove the option from your adapter configuration as it no longer exists: ```diff // astro.config.mjs import { defineConfig } from 'astro/config' import node from '@&#8203;astrojs/node' export default defineConfig({ adapter: node({ mode: 'standalone', - experimentalErrorPageHost: 'http://localhost:4321' }) }) ``` You can replicate the previous behavior by checking the response status in a middleware and fetching the prerendered page yourself: ```ts // src/middleware.ts import { defineMiddleware } from 'astro:middleware'; export const onRequest = defineMiddleware(async (ctx, next) => { const response = await next(); if (response.status === 404 || response.status === 500) { return fetch(`http://localhost:4321/${response.status}.html`); } return response; }); ``` ##### Minor Changes - [#&#8203;15258](https://github.com/withastro/astro/pull/15258) [`d339a18`](https://github.com/withastro/astro/commit/d339a182b387a7a1b0d5dd0d67a0638aaa2b4262) Thanks [@&#8203;ematipico](https://github.com/ematipico)! - Stabilizes the adapter feature `experimentalStatiHeaders`.

The default limit is 1 GB. Set the value in bytes, or pass `0` to disable the limit entirely: ```js import node from '@&#8203;astrojs/node'; import { defineConfig } from 'astro/config'; export default defineConfig({ adapter: node({ mode: 'standalone', bodySizeLimit: 1024 * 1024 * 100, // 100 MB }), }); ``` - [#&#8203;15006](https://github.com/withastro/astro/pull/15006) [`f361730`](https://github.com/withastro/astro/commit/f361730bc820c01a2ec3e508ac940be8077d8c04) Thanks [@&#8203;florian-lefebvre](https://github.com/florian-lefebvre)! - Adds new session driver object shape For greater flexibility and improved consistency with other Astro code, session drivers are now specified as an object: ```diff -import { defineConfig } from 'astro/config' +import { defineConfig, sessionDrivers } from 'astro/config' export default defineConfig({ session: { - driver: 'redis', - options: { - url: process.env.REDIS_URL - }, + driver: sessionDrivers.redis({ + url: process.env.REDIS_URL + }), } }) ``` Specifying the session driver as a string has been deprecated, but will continue to work until this feature is removed completely in a future major version.

- **BREAKING CHANGE to the v6 beta Adapter API only**: renames `entryType` to `entrypointResolution` and updates possible values Astro 6 introduced a way to let adapters have more control over the entrypoint by passing `entryType: 'self'` to `setAdapter()`. However during beta development, the name was unclear and confusing. `entryType` is now renamed to `entrypointResolution` and its possible values are updated: - `legacy-dynamic` becomes `explicit`. - `self` becomes `auto`. If you are building an adapter with v6 beta and specifying `entryType`, update it: ```diff setAdapter({ // ... - entryType: 'legacy-dynamic' + entrypointResolution: 'explicit' }) setAdapter({ // ... - entryType: 'self' + entrypointResolution: 'auto' }) ``` - [#&#8203;14426](https://github.com/withastro/astro/pull/14426) [`861b9cc`](https://github.com/withastro/astro/commit/861b9cc770a05d9fcfcb2f1f442a3ba41e94b510) Thanks [@&#8203;florian-lefebvre](https://github.com/florian-lefebvre)!

If you were using experimental CSP runtime utilities, you must now access methods conditionally: ```diff -Astro.csp.insertDirective("default-src 'self'"); +Astro.csp?.insertDirective("default-src 'self'"); ``` - [#&#8203;14445](https://github.com/withastro/astro/pull/14445) [`ecb0b98`](https://github.com/withastro/astro/commit/ecb0b98396f639d830a99ddb5895ab9223e4dc87) Thanks [@&#8203;florian-lefebvre](https://github.com/florian-lefebvre)! - Astro v6.0 upgrades to Vite v7.0 as the development server and production bundler - ([v6 upgrade guidance](https://docs.astro.build/en/guides/upgrade-to/v6/#vite-70)) - [#&#8203;15407](https://github.com/withastro/astro/pull/15407) [`aedbbd8`](https://github.com/withastro/astro/commit/aedbbd818628bed0533cdd627b73e2c5365aa17e) Thanks [@&#8203;ematipico](https://github.com/ematipico)! - Changes how styles of responsive images are emitted - ([v6 upgrade guidance](https://docs.astro.build/en/guides/upgrade-to/v6/#changed-how-responsive-image-styles-are-emitted)) - [#&#8203;14306](https://github.com/withastro/astro/pull/14306) [`141c4a2`](https://github.com/withastro/astro/commit/141c4a26419fe5bb4341953ea5a0a861d9b398c0) Thanks [@&#8203;ematipico](https://github.com/ematipico)! - Changes integration hooks and HMR access patterns in the Integration API - ([v6 upgrade guidance](https://docs.astro.build/en/guides/upgrade-to/v6/#changed-integration-hooks-and-hmr-access-patterns-integration-api)) - [#&#8203;14306](https://github.com/withastro/astro/pull/14306) [`141c4a2`](https://github.com/withastro/astro/commit/141c4a26419fe5bb4341953ea5a0a861d9b398c0) Thanks [@&#8203;ematipico](https://github.com/ematipico)! - Removes the unused `astro:ssr-manifest` virtual module - ([v6 upgrade guidance](https://docs.astro.build/en/guides/upgrade-to/v6/#removed-astrossr-manifest-virtual-module-integration-api)) - [#&#8203;14485](https://github.com/withastro/astro/pull/14485) [`6f67c6e`](https://github.com/withastro/astro/commit/6f67c6eef2647ef1a1eab78a65a906ab633974bb) Thanks [@&#8203;florian-lefebvre](https://github.com/florian-lefebvre)! - Updates `import.meta.env` values to always be inlined - ([v6 upgrade guidance](https://docs.astro.build/en/guides/upgrade-to/v6/#changed-importmetaenv-values-are-always-inlined)) - [#&#8203;14480](https://github.com/withastro/astro/pull/14480) [`36a461b`](https://github.com/withastro/astro/commit/36a461bf3f64c467bc52aecf511cd831d238e18b) Thanks [@&#8203;florian-lefebvre](https://github.com/florian-lefebvre)! - Updates `<script>` and `<style>` tags to render in the order they are defined - ([v6 upgrade guidance](https://docs.astro.build/en/guides/upgrade-to/v6/#changed-script-and-style-tags-are-rendered-in-the-order-they-are-defined)) - [#&#8203;14407](https://github.com/withastro/astro/pull/14407) [`3bda3ce`](https://github.com/withastro/astro/commit/3bda3ce4edcb1bd1349890c6ed8110f05954c791) Thanks [@&#8203;ascorbic](https://github.com/ascorbic)! - Removes legacy content collection support - ([v6 upgrade guidance](https://docs.astro.build/en/guides/upgrade-to/v6/#removed-legacy-content-collections)) ##### Minor Changes - [#&#8203;14306](https://github.com/withastro/astro/pull/14306) [`141c4a2`](https://github.com/withastro/astro/commit/141c4a26419fe5bb4341953ea5a0a861d9b398c0) Thanks [@&#8203;ematipico](https://github.com/ematipico)! - Adds new optional properties to `setAdapter()` for adapter entrypoint handling in the Adapter API **Changes:** - New optional properties: - `entryType?: 'self' | 'legacy-dynamic'` - determines if the adapter provides its own entrypoint (`'self'`) or if Astro constructs one (`'legacy-dynamic'`, default) **Migration:** Adapter authors can optionally add these properties to support custom dev entrypoints.

Previously, `inferRemoteSize()` had a fixed implementation that fetched the entire image to determine its dimensions. With this new helper function that extends `inferRemoteSize()`, you can now override or extend how remote image metadata is retrieved. This enables use cases such as: - Caching: Storing image dimensions in a database or local cache to avoid redundant network requests. - Provider APIs: Using a specific image provider's API (like Cloudinary or Vercel) to get dimensions without downloading the file. For example, you can add a simple cache layer to your existing image service: ```js const cache = new Map(); const myService = { ...baseService, async getRemoteSize(url, imageConfig) { if (cache.has(url)) return cache.get(url); const result = await baseService.getRemoteSize(url, imageConfig); cache.set(url, result); return result; }, }; ``` See the [Image Services API reference documentation](https://docs.astro.build/en/reference/image-service-reference/#getremotesize) for more information. - [#&#8203;15077](https://github.com/withastro/astro/pull/15077) [`a164c77`](https://github.com/withastro/astro/commit/a164c77336059f2dc3e7f7fe992aa754ed145ef3) Thanks [@&#8203;matthewp](https://github.com/matthewp)! - Updates the Integration API to add `setPrerenderer()` to the `astro:build:start` hook, allowing adapters to provide custom prerendering logic. The new API accepts either an `AstroPrerenderer` object directly, or a factory function that receives the default prerenderer: ```js 'astro:build:start': ({ setPrerenderer }) => { setPrerenderer((defaultPrerenderer) => ({ name: 'my-prerenderer', async setup() { // Optional: called once before prerendering starts }, async getStaticPaths() { // Returns array of { pathname: string, route: RouteData } return defaultPrerenderer.getStaticPaths(); }, async render(request, { routeData }) { // request: Request // routeData: RouteData // Returns: Response }, async teardown() { // Optional: called after all pages are prerendered } })); } ``` Also adds the `astro:static-paths` virtual module, which exports a `StaticPaths` class for adapters to collect all prerenderable paths from within their target runtime. This is useful when implementing a custom prerenderer that runs in a non-Node environment: ```js // In your adapter's request handler (running in target runtime) import { App } from 'astro/app'; import { StaticPaths } from 'astro:static-paths'; export function createApp(manifest) { const app = new App(manifest); return { async fetch(request) { const { pathname } = new URL(request.url); // Expose endpoint for prerenderer to get static paths if (pathname === '/__astro_static_paths') { const staticPaths = new StaticPaths(app); const paths = await staticPaths.getAll(); return new Response(JSON.stringify({ paths })); } // Normal request handling return app.render(request); }, }; } ``` See the [adapter reference](https://docs.astro.build/en/reference/adapter-reference/#custom-prerenderer) for more details on implementing a custom prerenderer. - [#&#8203;15345](https://github.com/withastro/astro/pull/15345) [`840fbf9`](https://github.com/withastro/astro/commit/840fbf9e4abc7f847e23da8d67904ffde4d95fff) Thanks [@&#8203;matthewp](https://github.com/matthewp)! - Adds a new `emitClientAsset` function to `astro/assets/utils` for integration authors.

The `npm` font provider allows you to add fonts either from locally installed packages in `node_modules` or from a CDN. Set `fontProviders.npm()` as your fonts provider along with the required `name` and `cssVariable` values, and add `options` as needed: ```js import { defineConfig, fontProviders } from 'astro/config'; export default defineConfig({ experimental: { fonts: [ { name: 'Roboto', provider: fontProviders.npm(), cssVariable: '--font-roboto', }, ], }, }); ``` See the [NPM font provider reference documentation](https://docs.astro.build/en/reference/font-provider-reference/#npm) for more details. - [#&#8203;15471](https://github.com/withastro/astro/pull/15471) [`32b4302`](https://github.com/withastro/astro/commit/32b430213bbe51898b77ec2eadbacb9dfb220f75) Thanks [@&#8203;ematipico](https://github.com/ematipico)! - Adds a new experimental flag `queuedRendering` to enable a queue-based rendering engine The new engine is based on a two-pass process, where the first pass traverses the tree of components, emits an ordered queue, and then the queue is rendered. The new engine does not use recursion, and comes with two customizable options. Early benchmarks showed significant speed improvements and memory efficiency in big projects. ##### Queue-rendered based The new engine can be enabled in your Astro config with `experimental.queuedRendering.enabled` set to `true`, and can be further customized with additional sub-features. ```js // astro.config.mjs export default defineConfig({ experimental: { queuedRendering: { enabled: true, }, }, }); ``` ##### Pooling With the new engine enabled, you now have the option to have a pool of nodes that can be saved and reused across page rendering. Node pooling has no effect when rendering pages on demand (SSR) because these rendering requests don't share memory. However, it can be very useful for performance when building static pages. ```js // astro.config.mjs export default defineConfig({ experimental: { queuedRendering: { enabled: true, poolSize: 2000, // store up to 2k nodes to be reused across renderers }, }, }); ``` ##### Content caching The new engine additionally unlocks a new `contentCache` option. This allows you to cache values of nodes during the rendering phase. This is currently a boolean feature with no further customization (e.g. size of cache) that uses sensible defaults for most large content collections: When disabled, the pool engine won't cache strings, but only types. ```js // astro.config.mjs export default defineConfig({ experimental: { queuedRendering: { enabled: true, contentCache: true, // enable re-use of node values }, }, }); ``` For more information on enabling and using this feature in your project, see the [experimental queued rendering docs](https://docs.astro.build/en/reference/experimental-flags/queued-rendering/) for more details. - [#&#8203;14888](https://github.com/withastro/astro/pull/14888) [`4cd3fe4`](https://github.com/withastro/astro/commit/4cd3fe412bddbb0deb1383e83f3f8ae6e72596af) Thanks [@&#8203;OliverSpeir](https://github.com/OliverSpeir)! - Updates `astro add cloudflare` to better setup types, by adding `./worker-configuration.d.ts` to tsconfig includes and a `generate-types` script to package.json - [#&#8203;15646](https://github.com/withastro/astro/pull/15646) [`0dd9d00`](https://github.com/withastro/astro/commit/0dd9d00cf8be38c53217426f6b0e155a6f7c2a22) Thanks [@&#8203;delucis](https://github.com/delucis)! - Removes redundant `fetchpriority` attributes from the output of Astro’s `<Image>` component Previously, Astro would always include `fetchpriority="auto"` on images not using the `priority` attribute.

This feature only impacts adapter authors. If your adapter supports `edgeMiddleware`, you should upgrade to the new `middlewareMode` option to specify the middleware mode for your adapter as soon as possible. The `edgeMiddleware` feature is deprecated and will be removed in a future major release. ```diff export default function createIntegration() { return { name: '@&#8203;example/my-adapter', hooks: { 'astro:config:done': ({ setAdapter }) => { setAdapter({ name: '@&#8203;example/my-adapter', serverEntrypoint: '@&#8203;example/my-adapter/server.js', adapterFeatures: { - edgeMiddleware: true + middlewareMode: 'edge' } }); }, }, }; } ``` - [#&#8203;15694](https://github.com/withastro/astro/pull/15694) [`66449c9`](https://github.com/withastro/astro/commit/66449c930e73e9a58ce547b9c32635a98a310966) Thanks [@&#8203;matthewp](https://github.com/matthewp)! - Adds `preserveBuildClientDir` option to adapter features Adapters can now opt in to preserving the client/server directory structure for static builds by setting `preserveBuildClientDir: true` in their adapter features. When enabled, static builds will output files to `build.client` instead of directly to `outDir`. This is useful for adapters that require a consistent directory structure regardless of the build output type, such as deploying to platforms with specific file organization requirements. ```js // my-adapter/index.js export default function myAdapter() { return { name: 'my-adapter', hooks: { 'astro:config:done': ({ setAdapter }) => { setAdapter({ name: 'my-adapter', adapterFeatures: { buildOutput: 'static', preserveBuildClientDir: true, }, }); }, }, }; } ``` - [#&#8203;15332](https://github.com/withastro/astro/pull/15332) [`7c55f80`](https://github.com/withastro/astro/commit/7c55f80fa1fd91f8f71ad60437f81e6c7f98f69d) Thanks [@&#8203;matthewp](https://github.com/matthewp)! - Adds a `fileURL` option to `renderMarkdown` in content loaders, enabling resolution of relative image paths.

Astro's implementation of responsive image styles has been updated to be compatible with a configured Content Security Policy. Instead of, injecting style elements at runtime, Astro will now generate your styles at build time using a combination of `class=""` and `data-*` attributes. This means that your processed styles are loaded and hashed out of the box by Astro. If you were previously choosing between Astro's CSP feature and including responsive images on your site, you may now use them together. - [#&#8203;15543](https://github.com/withastro/astro/pull/15543) [`d43841d`](https://github.com/withastro/astro/commit/d43841dfa8998c4dc1a510a2b120fedbd9ce77c6) Thanks [@&#8203;Princesseuh](https://github.com/Princesseuh)! - Adds a new `experimental.rustCompiler` flag to opt into the experimental Rust-based Astro compiler This experimental compiler is faster, provides better error messages, and generally has better support for modern JavaScript, TypeScript, and CSS features. After enabling in your Astro config, the `@astrojs/compiler-rs` package must also be installed into your project separately: ```js import { defineConfig } from 'astro/config'; export default defineConfig({ experimental: { rustCompiler: true, }, }); ``` This new compiler is still in early development and may exhibit some differences compared to the existing Go-based compiler. Notably, this compiler is generally more strict in regard to invalid HTML syntax and may throw errors in cases where the Go-based compiler would have been more lenient. For example, unclosed tags (e.g. `<p>My paragraph`) will now result in errors. For more information about using this experimental feature in your project, especially regarding expected differences and limitations, please see the [experimental Rust compiler reference docs](https://docs.astro.build/en/reference/experimental-flags/rust-compiler/). To give feedback on the compiler, or to keep up with its development, see the [RFC for a new compiler for Astro](https://github.com/withastro/roadmap/discussions/1306) for more information and discussion. - [#&#8203;15349](https://github.com/withastro/astro/pull/15349) [`a257c4c`](https://github.com/withastro/astro/commit/a257c4c3c7f0cdc5089b522ed216401d46d214c9) Thanks [@&#8203;ascorbic](https://github.com/ascorbic)! - Passes collection name to live content loaders Live content collection loaders now receive the collection name as part of their parameters.

This feature allows you to use fonts from both your file system and several built-in supported providers (e.g. Google, Fontsource, Bunny) through a unified API. Keep your site performant thanks to sensible defaults and automatic optimizations including preloading and fallback font generation. To enable this feature, configure `fonts` with one or more fonts: ```js title="astro.config.mjs" import { defineConfig, fontProviders } from 'astro/config'; export default defineConfig({ fonts: [ { provider: fontProviders.fontsource(), name: 'Roboto', cssVariable: '--font-roboto', }, ], }); ``` Import and include the `<Font />` component with the required `cssVariable` property in the head of your page, usually in a dedicated `Head.astro` component or in a layout component directly: ```astro --- // src/layouts/Layout.astro import { Font } from 'astro:assets'; --- <html> <head> <Font cssVariable="--font-roboto" preload /> </head> <body> <slot /> </body> </html> ``` In any page rendered with that layout, including the layout component itself, you can now define styles with your font's `cssVariable` to apply your custom font. In the following example, the `<h1>` heading will have the custom font applied, while the paragraph `<p>` will not. ```astro --- // src/pages/example.astro import Layout from '../layouts/Layout.astro'; --- <Layout> <h1>In a galaxy far, far away...</h1> <p>Custom fonts make my headings much cooler!</p> <style> h1 { font-family: var('--font-roboto'); } </style> </Layout> ``` Visit the updated [fonts guide](https://docs.astro.build/en/guides/fonts/) to learn more about adding custom fonts to your project. - [#&#8203;14550](https://github.com/withastro/astro/pull/14550) [`9c282b5`](https://github.com/withastro/astro/commit/9c282b5e6d3f0d678bc478a863e883fa4765dd17) Thanks [@&#8203;ascorbic](https://github.com/ascorbic)! - Adds support for live content collections Live content collections are a new type of [content collection](https://docs.astro.build/en/guides/content-collections/) that fetch their data at runtime rather than build time. This allows you to access frequently updated data from CMSs, APIs, databases, or other sources using a unified API, without needing to rebuild your site when the data changes. ##### Live collections vs build-time collections In Astro 5.0, the content layer API added support for adding diverse content sources to content collections. You can create loaders that fetch data from any source at build time, and then access it inside a page via `getEntry()` and `getCollection()`. The data is cached between builds, giving fast access and updates. However, there was no method for updating the data store between builds, meaning any updates to the data needed a full site deploy, even if the pages are rendered on demand. This meant that content collections were not suitable for pages that update frequently. Instead, these pages tended to access the APIs directly in the frontmatter. This worked, but it led to a lot of boilerplate, and meant users didn't benefit from the simple, unified API that content loaders offer. In most cases, users tended to individually create loader libraries shared between pages. Live content collections ([introduced experimentally in Astro 5.10](https://astro.build/blog/live-content-collections-deep-dive/)) solve this problem by allowing you to create loaders that fetch data at runtime, rather than build time. This means that the data is always up-to-date, without needing to rebuild the site. ##### How to use To use live collections, create a new `src/live.config.ts` file (alongside your `src/content.config.ts` if you have one) to define your live collections with a live content loader using the new `defineLiveCollection()` function from the `astro:content` module: ```ts title="src/live.config.ts" import { defineLiveCollection } from 'astro:content'; import { storeLoader } from '@&#8203;mystore/astro-loader'; const products = defineLiveCollection({ loader: storeLoader({ apiKey: process.env.STORE_API_KEY, endpoint: 'https://api.mystore.com/v1', }), }); export const collections = { products }; ``` You can then use the `getLiveCollection()` and `getLiveEntry()` functions to access your live data, along with error handling (since anything can happen when requesting live data!): ```astro --- import { getLiveCollection, getLiveEntry, render } from 'astro:content'; // Get all products const { entries: allProducts, error } = await getLiveCollection('products'); if (error) { // Handle error appropriately console.error(error.message); } // Get products with a filter (if supported by your loader) const { entries: electronics } = await getLiveCollection('products', { category: 'electronics' }); // Get a single product by ID (string syntax) const { entry: product, error: productError } = await getLiveEntry('products', Astro.params.id); if (productError) { return Astro.redirect('/404'); } // Get a single product with a custom query (if supported by your loader) using a filter object const { entry: productBySlug } = await getLiveEntry('products', { slug: Astro.params.slug }); const { Content } = await render(product); --- <h1>{product.data.title}</h1> <Content /> ``` ##### Upgrading from experimental live collections If you were using the experimental feature, you must remove the `experimental.liveContentCollections` flag from your `astro.config.*` file: ```diff export default defineConfig({ // ... - experimental: { - liveContentCollections: true, - }, }); ``` No other changes to your project code are required as long as you have been keeping up with Astro 5.x patch releases, which contained breaking changes to this experimental feature. If you experience problems with your live collections after upgrading to Astro v6 and removing this flag, please review the [Astro CHANGELOG from 5.10.2](https://github.com/withastro/astro/blob/main/packages/astro/CHANGELOG.md#5102) onwards for any potential updates you might have missed, or follow the [current v6 documentation for live collections](https://docs.astro.build/en/guides/content-collections/). - [#&#8203;15548](https://github.com/withastro/astro/pull/15548) [`5b8f573`](https://github.com/withastro/astro/commit/5b8f5737feb1a051b7cbd5d543dd230492e5211f) Thanks [@&#8203;florian-lefebvre](https://github.com/florian-lefebvre)! - Adds a new optional `embeddedLangs` prop to the `<Code />` component to support languages beyond the primary `lang` This allows, for example, highlighting `.vue` files with a `<script setup lang="tsx">` block correctly: ```astro --- import { Code } from 'astro:components'; const code = ` <script setup lang="tsx"> const Text = ({ text }: { text: string }) => <div>{text}</div>; </script> <template> <Text text="hello world" /> </template>`; --- <Code {code} lang="vue" embeddedLangs={['tsx']} /> ``` See the [`<Code />` component documentation](https://docs.astro.build/en/guides/syntax-highlighting/#code-) for more details. - [#&#8203;14826](https://github.com/withastro/astro/pull/14826) [`170f64e`](https://github.com/withastro/astro/commit/170f64e977290b8f9d316b5f283bd03bae33ddde) Thanks [@&#8203;florian-lefebvre](https://github.com/florian-lefebvre)! - Adds an option `prerenderConflictBehavior` to configure the behavior of conflicting prerendered routes By default, Astro warns you during the build about any conflicts between multiple dynamic routes that can result in the same output path. For example `/blog/[slug]` and `/blog/[...all]` both could try to prerender the `/blog/post-1` path. In such cases, Astro renders only the [highest priority route](https://docs.astro.build/en/guides/routing/#route-priority-order) for the conflicting path. This allows your site to build successfully, although you may discover that some pages are rendered by unexpected routes. With the new `prerenderConflictBehavior` configuration option, you can now configure this further: - `prerenderConflictBehavior: 'error'` fails the build - `prerenderConflictBehavior: 'warn'` (default) logs a warning and the highest-priority route wins - `prerenderConflictBehavior: 'ignore'` silently picks the highest-priority route when conflicts occur ```diff import { defineConfig } from 'astro/config'; export default defineConfig({ + prerenderConflictBehavior: 'error', }); ``` - [#&#8203;14946](https://github.com/withastro/astro/pull/14946) [`95c40f7`](https://github.com/withastro/astro/commit/95c40f7109ce240206c3951761a7bb439dd809cb) Thanks [@&#8203;ematipico](https://github.com/ematipico)! - Removes the `experimental.csp` flag and replaces it with a new configuration option `security.csp` - ([v6 upgrade guidance](https://docs.astro.build/en/guides/upgrade-to/v6/#experimental-flags)) - [#&#8203;15579](https://github.com/withastro/astro/pull/15579) [`08437d5`](https://github.com/withastro/astro/commit/08437d531e31b79a42333a9f7aabaa9fe646ce4f) Thanks [@&#8203;ascorbic](https://github.com/ascorbic)! - Adds two new experimental flags for a Route Caching API and further configuration-level Route Rules for controlling SSR response caching. Route caching gives you a platform-agnostic way to cache server-rendered responses, based on web standard cache headers. You set caching directives in your routes using `Astro.cache` (in `.astro` pages) or `context.cache` (in API routes and middleware), and Astro translates them into the appropriate headers or runtime behavior depending on your adapter. You can also define cache rules for routes declaratively in your config using `experimental.routeRules`, without modifying route code. This feature requires on-demand rendering. Prerendered pages are already static and do not use route caching. ##### Getting started Enable the feature by configuring `experimental.cache` with a cache provider in your Astro config: ```js // astro.config.mjs import { defineConfig } from 'astro/config'; import node from '@&#8203;astrojs/node'; import { memoryCache } from 'astro/config'; export default defineConfig({ adapter: node({ mode: 'standalone' }), experimental: { cache: { provider: memoryCache(), }, }, }); ``` ##### Using `Astro.cache` and `context.cache` In `.astro` pages, use `Astro.cache.set()` to control caching: ```astro --- // src/pages/index.astro Astro.cache.set({ maxAge: 120, // Cache for 2 minutes swr: 60, // Serve stale for 1 minute while revalidating tags: ['home'], // Tag for targeted invalidation }); --- <html><body>Cached page</body></html> ``` In API routes and middleware, use `context.cache`: ```ts // src/pages/api/data.ts export function GET(context) { context.cache.set({ maxAge: 300, tags: ['api', 'data'], }); return Response.json({ ok: true }); } ``` ##### Cache options `cache.set()` accepts the following options: - **`maxAge`** (number): Time in seconds the response is considered fresh. - **`swr`** (number): Stale-while-revalidate window in seconds. During this window, stale content is served while a fresh response is generated in the background. - **`tags`** (string\[]): Cache tags for targeted invalidation. Tags accumulate across multiple `set()` calls within a request. - **`lastModified`** (Date): When multiple `set()` calls provide `lastModified`, the most recent date wins. - **`etag`** (string): Entity tag for conditional requests. Call `cache.set(false)` to explicitly opt out of caching for a request. Multiple calls to `cache.set()` within a single request are merged: scalar values use last-write-wins, `lastModified` uses most-recent-wins, and tags accumulate. ##### Invalidation Purge cached entries by tag or path using `cache.invalidate()`: ```ts // Invalidate all entries tagged 'data' await context.cache.invalidate({ tags: ['data'] }); // Invalidate a specific path await context.cache.invalidate({ path: '/api/data' }); ``` ##### Config-level route rules Use `experimental.routeRules` to set default cache options for routes without modifying route code. Supports Nitro-style shortcuts for ergonomic configuration: ```js import { memoryCache } from 'astro/config'; export default defineConfig({ experimental: { cache: { provider: memoryCache(), }, routeRules: { // Shortcut form (Nitro-style) '/api/*': { swr: 600 }, // Full form with nested cache '/products/*': { cache: { maxAge: 3600, tags: ['products'] } }, }, }, }); ``` Route patterns support static paths, dynamic parameters (`[slug]`), and rest parameters (`[...path]`). Per-route `cache.set()` calls merge with (and can override) the config-level defaults. You can also read the current cache state via `cache.options`: ```ts const { maxAge, swr, tags } = context.cache.options; ``` ##### Cache providers Cache behavior is determined by the configured **cache provider**. There are two types: - **CDN providers** set response headers (e.g. `CDN-Cache-Control`, `Cache-Tag`) and let the CDN handle caching. Astro strips these headers before sending the response to the client. - **Runtime providers** implement `onRequest()` to intercept and cache responses in-process, adding an `X-Astro-Cache` header (HIT/MISS/STALE) for observability. ##### Built-in memory cache provider Astro includes a built-in, in-memory LRU runtime cache provider. Import `memoryCache` from `astro/config` to configure it. Features: - In-memory LRU cache with configurable max entries (default: 1000) - Stale-while-revalidate support - Tag-based and path-based invalidation - `X-Astro-Cache` response header: `HIT`, `MISS`, or `STALE` - Query parameter sorting for better hit rates (`?b=2&a=1` and `?a=1&b=2` hit the same entry) - Common tracking parameters (`utm_*`, `fbclid`, `gclid`, etc.) excluded from cache keys by default - `Vary` header support — responses that set `Vary` automatically get separate cache entries per variant - Configurable query parameter filtering via `query.exclude` (glob patterns) and `query.include` (allowlist) For more information on enabling and using this feature in your project, see the [Experimental Route Caching docs](https://docs.astro.build/en/reference/experimental-flags/route-caching/). For a complete overview and to give feedback on this experimental API, see the [Route Caching RFC](https://github.com/withastro/roadmap/pull/1245). - [#&#8203;15483](https://github.com/withastro/astro/pull/15483) [`7be3308`](https://github.com/withastro/astro/commit/7be3308bf4b1710a3f378ba338d09a8528e01e76) Thanks [@&#8203;florian-lefebvre](https://github.com/florian-lefebvre)! - Adds `streaming` option to the `createApp()` function in the Adapter API, mirroring the same functionality available when creating a new `App` instance An adapter's `createApp()` function now accepts `streaming` (defaults to `true`) as an option. HTML streaming breaks a document into chunks to send over the network and render on the page in order. This normally results in visitors seeing your HTML as fast as possible but factors such as network conditions and waiting for data fetches can block page rendering. HTML streaming helps with performance and generally provides a better visitor experience. In most cases, disabling streaming is not recommended. However, when you need to disable HTML streaming (e.g. your host only supports non-streamed HTML caching at the CDN level), you can opt out of the default behavior by passing `streaming: false` to `createApp()`: ```ts import { createApp } from 'astro/app/entrypoint'; const app = createApp({ streaming: false }); ``` See more about [the `createApp()` function](https://docs.astro.build/en/reference/adapter-reference/#createapp) in the Adapter API reference. ##### Patch Changes - [#&#8203;15423](https://github.com/withastro/astro/pull/15423) [`c5ea720`](https://github.com/withastro/astro/commit/c5ea720261a35324988147fbf69d8200e496e1d0) Thanks [@&#8203;matthewp](https://github.com/matthewp)! - Improves error message when a dynamic redirect destination does not match any existing route.

If you do not set this option, Astro continues to enforce the 1 MB default to help prevent abuse. ```js // astro.config.mjs export default defineConfig({ security: { actionBodySizeLimit: 10 * 1024 * 1024, // set to 10 MB }, }); ``` - [#&#8203;15176](https://github.com/withastro/astro/pull/15176) [`9265546`](https://github.com/withastro/astro/commit/92655460785e4b0a9eca9bac2e493a9c989dff47) Thanks [@&#8203;matthewp](https://github.com/matthewp)! - Fixes scripts in components not rendering when a sibling `<Fragment slot="...">` exists but is unused - Updated dependencies \[[`bbb5811`](https://github.com/withastro/astro/commit/bbb5811eb801a42dc091bb09ea19d6cde3033795), [`4ebc1e3`](https://github.com/withastro/astro/commit/4ebc1e328ac40e892078031ed9dfecf60691fd56), [`cb99214`](https://github.com/withastro/astro/commit/cb99214ebb991d1b929978f46e1b3ae68b561366), [`80f0225`](https://github.com/withastro/astro/commit/80f022559e81b5609a69ba31c7f0d93dcb0bf74d), [`727b0a2`](https://github.com/withastro/astro/commit/727b0a205eb765f1c36f13a73dfc69e17e44df8f), [`4e7f3e8`](https://github.com/withastro/astro/commit/4e7f3e8e6849c314a0ab031ebd7f23fb982f0529), [`a164c77`](https://github.com/withastro/astro/commit/a164c77336059f2dc3e7f7fe992aa754ed145ef3), [`1fa4177`](https://github.com/withastro/astro/commit/1fa41779c458123f707940a5253dbe6e540dbf7d), [`7c55f80`](https://github.com/withastro/astro/commit/7c55f80fa1fd91f8f71ad60437f81e6c7f98f69d), [`cf6ea6b`](https://github.com/withastro/astro/commit/cf6ea6b36b67c7712395ed3f9ca19cb14ba1a013), [`6f19ecc`](https://github.com/withastro/astro/commit/6f19ecc35adfb2ddaabbba2269630f95c13f5a57), [`f94d3c5`](https://github.com/withastro/astro/commit/f94d3c5313e5a7576cf2cb316a85d68d335a188f), [`a18d727`](https://github.com/withastro/astro/commit/a18d727fc717054df85177c8e0c3d38a5252f2da), [`240c317`](https://github.com/withastro/astro/commit/240c317faab52d7f22494e9181f5d2c2c404b0bd), [`745e632`](https://github.com/withastro/astro/commit/745e632fc590e41a5701509e9cc4ed971bdddf74)]: - [@&#8203;astrojs/markdown-remark](https://github.com/astrojs/markdown-remark)@&#8203;7.0.0 - [@&#8203;astrojs/internal-helpers](https://github.com/astrojs/internal-helpers)@&#8203;0.8.0 </details> --- ### Configuration 📅 **Schedule**: Branch creation - At any time (no schedule defined), Automerge - At any time (no schedule defined). 🚦 **Automerge**: Disabled by config.
