3.6.0

Minor Changes

  • #9090 c87223c21 Thanks @martrapp! - Take full control over the behavior of view transitions!

    Three new events now complement the existing astro:after-swap and astro:page-load events:

    javascript
    'astro:before-preparation'; // Control how the DOM and other resources of the target page are loaded
'astro:after-preparation'; // Last changes before taking off? Remove that loading indicator? Here you go!
'astro:before-swap'; // Control how the DOM is updated to match the new page

    The astro:before-* events allow you to change properties and strategies of the view transition implementation. The astro:after-* events are notifications that a phase is complete. Head over to docs to see the full view transitions lifecycle including these new events!

  • #9092 0ea4bd47e Thanks @smitbarmase! - Changes the fallback prefetch behavior on slow connections and when data saver mode is enabled. Instead of disabling prefetch entirely, the tap strategy will be used.

  • #9166 cba6cf32d Thanks @matthewp! - The Picture component is no longer experimental

    The <Picture /> component, part of astro:assets, has exited experimental status and is now recommended for use. There are no code changes to the component, and no upgrade to your project is necessary.

    This is only a change in documentation/recommendation. If you were waiting to use the <Picture /> component until it had exited the experimental stage, wait no more!

  • #9092 0ea4bd47e Thanks @smitbarmase! - Adds a ignoreSlowConnection option to the prefetch() API to prefetch even on data saver mode or slow connection.

3.5.0

Minor Changes

  • #8869 f5bdfa272 Thanks @matthewp! - ## Integration Hooks to add Middleware

    It's now possible in Astro for an integration to add middleware on behalf of the user. Previously when a third party wanted to provide middleware, the user would need to create a src/middleware.ts file themselves. Now, adding third-party middleware is as easy as adding a new integration.

    For integration authors, there is a new addMiddleware function in the astro:config:setup hook. This function allows you to specify a middleware module and the order in which it should be applied:

    js
    // my-package/middleware.js
import { defineMiddleware } from 'astro:middleware';

export const onRequest = defineMiddleware(async (context, next) => {
  const response = await next();

  if (response.headers.get('content-type') === 'text/html') {
    let html = await response.text();
    html = minify(html);
    return new Response(html, {
      status: response.status,
      headers: response.headers,
    });
  }

  return response;
});

    You can now add your integration's middleware and specify that it runs either before or after the application's own defined middleware (defined in src/middleware.{js,ts})

    js
    // my-package/integration.js
export function myIntegration() {
  return {
    name: 'my-integration',
    hooks: {
      'astro:config:setup': ({ addMiddleware }) => {
        addMiddleware({
          entrypoint: 'my-package/middleware',
          order: 'pre',
        });
      },
    },
  };
}

  • #8854 3e1239e42 Thanks @natemoo-re! - Provides a new, experimental build cache for Content Collections as part of the Incremental Build RFC. This includes multiple refactors to Astro's build process to optimize how Content Collections are handled, which should provide significant performance improvements for users with many collections.

    Users building a static site can opt-in to preview the new build cache by adding the following flag to your Astro config:

    js
    // astro.config.mjs
export default {
  experimental: {
    contentCollectionCache: true,
  },
};

    When this experimental feature is enabled, the files generated from your content collections will be stored in the cacheDir (by default, node_modules/.astro) and reused between builds. Most CI environments automatically restore files in node_modules/ by default.

    In our internal testing on the real world Astro Docs project, this feature reduces the bundling step of astro build from 133.20s to 10.46s, about 92% faster. The end-to-end astro build process used to take 4min 58s and now takes just over 1min for a total reduction of 80%.

    If you run into any issues with this experimental feature, please let us know!

    You can always bypass the cache for a single build by passing the --force flag to astro build.

    astro build --force

  • #8963 fda3a0213 Thanks @matthewp! - Form support in View Transitions router

    The <ViewTransitions /> router can now handle form submissions, allowing the same animated transitions and stateful UI retention on form posts that are already available on <a> links. With this addition, your Astro project can have animations in all of these scenarios:

    • Clicking links between pages.
    • Making stateful changes in forms (e.g. updating site preferences).
    • Manually triggering navigation via the navigate() API.

    This feature is opt-in for semver reasons and can be enabled by adding the handleForms prop to the `<ViewTransitions /> component:

    astro
    ---
// src/layouts/MainLayout.astro
import { ViewTransitions } from 'astro:transitions';
---

<html>
  <head>
    <!-- ... -->
    <ViewTransitions handleForms />
  </head>
  <body>
    <!-- ... -->
  </body>
</html>

    Just as with links, if you don't want the routing handling a form submission, you can opt out on a per-form basis with the data-astro-reload property:

    astro
    ---
// src/components/Contact.astro
---

<form class="contact-form" action="/request" method="post" data-astro-reload>
  <!-- ...-->
</form>

    Form support works on post method="get" and method="post" forms.

  • #8954 f0031b0a3 Thanks @Princesseuh! - Updates the Image Services API to now delete original images from the final build that are not used outside of the optimization pipeline. For users with a large number of these images (e.g. thumbnails), this should reduce storage consumption and deployment times.

  • #8984 26b1484e8 Thanks @Princesseuh! - Adds a new property propertiesToHash to the Image Services API to allow specifying which properties of getImage() / <Image /> / <Picture /> should be used for hashing the result files when doing local transformations. For most services, this will include properties such as src, width or quality that directly changes the content of the generated image.

  • #9010 100b61ab5 Thanks @jasikpark! - The <Picture /> component will now use jpg and jpeg respectively as fallback formats when the original image is in those formats.

  • #8974 143bacf39 Thanks @ematipico! - Experimental support for i18n routing.

    Astro's experimental i18n routing API allows you to add your multilingual content with support for configuring a default language, computing relative page URLs, and accepting preferred languages provided by your visitor's browser. You can also specify fallback languages on a per-language basis so that your visitors can always be directed to existing content on your site.

    Enable the experimental routing option by adding an i18n object to your Astro configuration with a default location and a list of all languages to support:

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

export default defineConfig({
  experimental: {
    i18n: {
      defaultLocale: 'en',
      locales: ['en', 'es', 'pt-br'],
    },
  },
});

    Organize your content folders by locale depending on your i18n.routingStrategy, and Astro will handle generating your routes and showing your preferred URLs to your visitors.

    ├── src
│   ├── pages
│   │   ├── about.astro
│   │   ├── index.astro
│   │   ├── es
│   │   │   ├── about.astro
│   │   │   ├── index.astro
│   │   ├── pt-br
│   │   │   ├── about.astro
│   │   │   ├── index.astro

    Compute relative URLs for your links with getRelativeLocaleUrl from the new astro:i18n module:

    astro
    ---
import { getRelativeLocaleUrl } from 'astro:i18n';
const aboutUrl = getRelativeLocaleUrl('pt-br', 'about');
---

<p>Learn more <a href={aboutURL}>About</a> this site!</p>

    Enabling i18n routing also provides two new properties for browser language detection: Astro.preferredLocale and Astro.preferredLocaleList. These combine the browser's Accept-Language header, and your site's list of supported languages and can be used to automatically respect your visitor's preferred languages.

    Read more about Astro's experimental i18n routing in our documentation.

  • #8951 38e21d127 Thanks @bluwy! - Prefetching is now supported in core

    You can enable prefetching for your site with the prefetch: true config. It is enabled by default when using View Transitions and can also be used to configure the prefetch behaviour used by View Transitions.

    You can enable prefetching by setting prefetch:true in your Astro config:

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

export default defineConfig({
  prefetch: true,
});

    This replaces the @astrojs/prefetch integration, which is now deprecated and will eventually be removed. Visit the Prefetch guide for more information.

  • #8903 c5010aad3 Thanks @horo-fox! - Adds experimental support for multiple shiki themes with the new markdown.shikiConfig.experimentalThemes option.

Patch Changes

  • #9016 1ecc9aa32 Thanks @Princesseuh! - Add ability to "Click to go editor" on audited elements in the dev overlay

  • #9029 29b83e9e4 Thanks @Princesseuh! - Use UInt8Array instead of Buffer for both the input and return values of the transform() hook of the Image Service API to ensure compatibility with non-Node runtimes.

    This change is unlikely to affect you, but if you were previously relying on the return value being a Buffer, you may convert an UInt8Array to a Buffer using Buffer.from(your_array).

  • #8755 fe4079f05 Thanks @matthewp! - Page Partials

    A page component can now be identified as a partial page, which will render its HTML content without including a <! DOCTYPE html> declaration nor any <head> content.

    A rendering library, like htmx or Stimulus or even just jQuery can access partial content on the client to dynamically update only parts of a page.

    Pages marked as partials do not have a doctype or any head content included in the rendered result. You can mark any page as a partial by setting this option:

    astro
    ---
export const partial = true;
---

<li>This is a single list item.</li>

    Other valid page files that can export a value (e.g. .mdx) can also be marked as partials.

    Read more about Astro page partials in our documentation.

  • #8821 4740d761a Thanks @Princesseuh! - Improved image optimization performance

    Astro will now generate optimized images concurrently at build time, which can significantly speed up build times for sites with many images. Additionally, Astro will now reuse the same buffer for all variants of an image. This should improve performance for websites with many variants of the same image, especially when using remote images.

    No code changes are required to take advantage of these improvements.

  • #8757 e99586787 Thanks @Princesseuh! - Dev Overlay (experimental)

    Provides a new dev overlay for your browser preview that allows you to inspect your page islands, see helpful audits on performance and accessibility, and more. A Dev Overlay Plugin API is also included to allow you to add new features and third-party integrations to it.

    You can enable access to the dev overlay and its API by adding the following flag to your Astro config:

    ts
    // astro.config.mjs
export default {
  experimental: {
    devOverlay: true,
  },
};

    Read the Dev Overlay Plugin API documentation for information about building your own plugins to integrate with Astro's dev overlay.

  • #8880 8c3d4a859 Thanks @alexanderniebuhr! - Moves the logic for overriding the image service out of core and into adapters. Also fixes a regression where a valid astro:assets image service configuration could be overridden.

Minor Changes

  • #8808 2993055be Thanks @delucis! - Adds support for an --outDir CLI flag to astro build

  • #8502 c4270e476 Thanks @bluwy! - Updates the internal shiki syntax highlighter to shikiji, an ESM-focused alternative that simplifies bundling and maintenance.

    There are no new options and no changes to how you author code blocks and syntax highlighting.

    Potentially breaking change: While this refactor should be transparent for most projects, the transition to shikiji now produces a smaller HTML markup by attaching a fallback color style to the pre or code element, instead of to the line span directly. For example:

    Before:

    html
    <code class="astro-code" style="background-color: #24292e">
  <pre>
    <span class="line" style="color: #e1e4e8">my code</span>
  </pre>
</code>

    After:

    html
    <code class="astro-code" style="background-color: #24292e; color: #e1e4e8">
  <pre>
    <span class="line">my code<span>
  </pre>
</code>

    This does not affect the colors as the span will inherit the color from the parent, but if you're relying on a specific HTML markup, please check your site carefully after upgrading to verify the styles.

  • #8798 f369fa250 Thanks @Princesseuh! - Fixed tsconfig.json's new array format for extends not working. This was done by migrating Astro to use tsconfck instead of tsconfig-resolver to find and parse tsconfig.json files.

  • #8620 b2ae9ee0c Thanks @Princesseuh! - Adds experimental support for generating srcset attributes and a new <Picture /> component.

    srcset support

    Two new properties have been added to Image and getImage(): densities and widths.

    These properties can be used to generate a srcset attribute, either based on absolute widths in pixels (e.g. [300, 600, 900]) or pixel density descriptors (e.g. ["2x"] or [1.5, 2]).

    astro
    ---
import { Image } from 'astro';
import myImage from './my-image.jpg';
---

<Image src={myImage} width={myImage.width / 2} densities={[1.5, 2]} alt="My cool image" />
    html

    Picture component

    The experimental <Picture /> component can be used to generate a <picture> element with multiple <source> elements.

    The example below uses the format property to generate a <source> in each of the specified image formats:

    astro
    ---
import { Picture } from 'astro:assets';
import myImage from './my-image.jpg';
---

<Picture src={myImage} formats={['avif', 'webp']} alt="My super image in multiple formats!" />

    The above code will generate the following HTML, and allow the browser to determine the best image to display:

    html
    <picture>
  <source srcset="..." type="image/avif" />
  <source srcset="..." type="image/webp" />
  
</picture>

    The Picture component takes all the same props as the Image component, including the new densities and widths properties.

3.2.0

Minor Changes

  • #8696 2167ffd72 Thanks @matthewp! - Support adding integrations dynamically

    Astro integrations can now themselves dynamically add and configure additional integrations during set-up. This makes it possible for integration authors to bundle integrations more intelligently for their users.

    In the following example, a custom integration checks whether @astrojs/sitemap is already configured. If not, the integration adds Astro’s sitemap integration, passing any desired configuration options:

    ts
    import sitemap from '@astrojs/sitemap';
import type { AstroIntegration } from 'astro';

const MyIntegration = (): AstroIntegration => {
  return {
    name: 'my-integration',

    'astro:config:setup': ({ config, updateConfig }) => {
      // Look for sitemap in user-configured integrations.
      const userSitemap = config.integrations.find(
        ({ name }) => name === '@astrojs/sitemap'
      );

      if (!userSitemap) {
        // If sitemap wasn’t found, add it.
        updateConfig({
          integrations: [sitemap({ /* opts */ }],
        });
      }
    },
  };
};

  • #8696 2167ffd72 Thanks @matthewp! - View transitions can now be triggered from JavaScript!

    Import the client-side router from "astro:transitions/client" and enjoy your new remote control for navigation:

    js
    import { navigate } from 'astro:transitions/client';

// Navigate to the selected option automatically.
document.querySelector('select').onchange = (ev) => {
  let href = ev.target.value;
  navigate(href);
};

  • #8696 2167ffd72 Thanks @matthewp! - Route Announcer in <ViewTransitions />

    The View Transitions router now does route announcement. When transitioning between pages with a traditional MPA approach, assistive technologies will announce the page title when the page finishes loading. This does not automatically happen during client-side routing, so visitors relying on these technologies to announce routes are not aware when a page has changed.

    The view transitions route announcer runs after the astro:page-load event, looking for the page <title> to announce. If one cannot be found, the announcer falls back to the first <h1> it finds, or otherwise announces the pathname. We recommend you always include a <title> in each page for accessibility.

    See the View Transitions docs for more on how accessibility is handled.

  • #8179 6011d52d3 Thanks @matthewp! - Astro 3.0 Release Candidate

  • #8188 80f1494cd Thanks @ematipico! - The build.split and build.excludeMiddleware configuration options are deprecated and have been replaced by options in the adapter config.

    If your config includes the build.excludeMiddleware option, replace it with edgeMiddleware in your adapter options:

     build: {
-        excludeMiddleware: true
     },
     adapter: netlify({

  • #8207 e45f30293 Thanks @natemoo-re! - Change the View Transition built-in animation options.

    The transition:animate value morph has been renamed to initial. Also, this is no longer the default animation.

    If no transition:animate directive is specified, your animations will now default to fade.

    Astro also supports a new transition:animate value, none. This value can be used on a page's <html> element to disable animated full-page transitions on an entire page.

  • #8188 c0de7a7b0 Thanks @ematipico! - Sharp is now the default image service used for astro:assets. If you would prefer to still use Squoosh, you can update your config with the following:

    ts
    import { defineConfig, squooshImageService } from 'astro/config';

// https://astro.build/config
export default defineConfig({
  image: {
    service: squooshImageService(),
  },
});

    However, not only do we recommend using Sharp as it is faster and more reliable, it is also highly likely that the Squoosh service will be removed in a future release.

  • #8188 3c3100851 Thanks @ematipico! - Remove support for Astro.__renderMarkdown which is used by @astrojs/markdown-component.

    The <Markdown /> component was deprecated in Astro v1 and is completely removed in v3. This integration must now be removed from your project.

    As an alternative, you can use community packages that provide a similar component like https://github.com/natemoo-re/astro-remote instead.

  • #8019 34cb20021 Thanks @bluwy! - Remove backwards-compatible kebab-case transform for camelCase CSS variable names passed to the style attribute. If you were relying on the kebab-case transform in your styles, make sure to use the camelCase version to prevent missing styles. For example:

    astro
    ---
const myValue = 'red';
---

<!-- input -->
<div style={{ '--myValue': myValue }}></div>

<!-- output (before) -->
<div style="--my-value:var(--myValue);--myValue:red"></div>

<!-- output (after) -->
<div style="--myValue:red"></div>
    diff
    <style>
  div {
-   color: var(--my-value);
+   color: var(--myValue);
  }
</style>

  • #8170 be6bbd2c8 Thanks @bluwy! - Remove deprecated config option types, deprecated script/style attributes, and deprecated image export from astro:content

  • #8188 7511a4980 Thanks @ematipico! - When using an adapter that supports neither Squoosh or Sharp, Astro will now automatically use an image service that does not support processing, but still provides the other benefits of astro:assets such as enforcing alt, no CLS etc to users

  • #7979 dbc97b121 Thanks @bluwy! - Export experimental dev, build, preview, and sync APIs from astro. These APIs allow you to run Astro's commands programmatically, and replaces the previous entry point that runs the Astro CLI.

    While these APIs are experimental, the inline config parameter is relatively stable without foreseeable changes. However, the returned results of these APIs are more likely to change in the future.

    ts
    import { dev, build, preview, sync, type AstroInlineConfig } from 'astro';

// Inline Astro config object.
// Provide a path to a configuration file to load or set options directly inline.
const inlineConfig: AstroInlineConfig = {
  // Inline-specific options...
  configFile: './astro.config.mjs',
  logLevel: 'info',
  // Standard Astro config options...
  site: 'https://example.com',
};

// Start the Astro dev server
const devServer = await dev(inlineConfig);
await devServer.stop();

// Build your Astro project
await build(inlineConfig);

// Preview your built project
const previewServer = await preview(inlineConfig);
await previewServer.stop();

// Generate types for your Astro project
await sync(inlineConfig);

  • #8188 7d2f311d4 Thanks @ematipico! - Removed support for old syntax of the API routes.

  • #8085 68efd4a8b Thanks @bluwy! - Remove exports for astro/internal/* and astro/runtime/server/* in favour of astro/runtime/*. Add new astro/compiler-runtime export for compiler-specific runtime code.

    These are exports for Astro's internal API and should not affect your project, but if you do use these entrypoints, you can migrate like below:

    diff
    - import 'astro/internal/index.js';
+ import 'astro/runtime/server/index.js';

- import 'astro/server/index.js';
+ import 'astro/runtime/server/index.js';
    diff
    import { transform } from '@astrojs/compiler';

const result = await transform(source, {
- internalURL: 'astro/runtime/server/index.js',
+ internalURL: 'astro/compiler-runtime',
  // ...
});

  • #7893 7bd1b86f8 Thanks @ematipico! - Implements a new scope style strategy called "attribute". When enabled, styles are applied using data-* attributes.

    The default value of scopedStyleStrategy is "attribute".

    If you want to use the previous behaviour, you have to use the "where" option:

    diff
    import { defineConfig } from 'astro/config';

export default defineConfig({
+    scopedStyleStrategy: 'where',
});

  • #7924 519a1c4e8 Thanks @matthewp! - Astro's JSX handling has been refactored with better support for each framework.

    Previously, Astro automatically scanned your components to determine which framework-specific transformations should be used. In practice, supporting advanced features like Fast Refresh with this approach proved difficult.

    Now, Astro determines which framework to use with include and exclude config options where you can specify files and folders on a per-framework basis. When using multiple JSX frameworks in the same project, users should manually control which files belong to each framework using the include and exclude options.

    js
    export default defineConfig({
  // The `include` config is only needed in projects that use multiple JSX frameworks;
  // if only using one no extra config is needed.
  integrations: [
    preact({
      include: ['**/preact/*'],
    }),
    react({
      include: ['**/react/*'],
    }),
    solid({
      include: ['**/solid/*'],
    }),
  ],
});

  • #8030 5208a3c8f Thanks @natemoo-re! - Removed duplicate astro/dist/jsx export. Please use the astro/jsx export instead

  • #8188 84af8ed9d Thanks @ematipico! - Remove MDX plugin re-ordering hack

  • #8180 f003e7364 Thanks @ematipico! - The scoped hash created by the Astro compiler is now lowercase.

  • #7878 0f637c71e Thanks @bluwy! - The value of import.meta.env.BASE_URL, which is derived from the base option, will no longer have a trailing slash added by default or when trailingSlash: "ignore" is set. The existing behavior of base in combination with trailingSlash: "always" or trailingSlash: "never" is unchanged.

    If your base already has a trailing slash, no change is needed.

    If your base does not have a trailing slash, add one to preserve the previous behaviour:

    diff
    // astro.config.mjs
- base: 'my-base',
+ base: 'my-base/',

  • #8118 8a5b0c1f3 Thanks @lilnasy! - Astro is smarter about CSS! Small stylesheets are now inlined by default, and no longer incur the cost of additional requests to your server. Your visitors will have to wait less before they see your pages, especially those in remote locations or in a subway.

    This may not be news to you if you had opted-in via the build.inlineStylesheets configuration. Stabilized in Astro 2.6 and set to "auto" by default for Starlight, this configuration allows you to reduce the number of requests for stylesheets by inlining them into <style> tags. The new default is "auto", which selects assets smaller than 4kB and includes them in the initial response.

    To go back to the previous default behavior, change build.inlineStylesheets to "never".

    ts
    import { defineConfig } from 'astro/config';

export default defineConfig({
  build: {
    inlineStylesheets: 'never',
  },
});

  • #8188 148e61d24 Thanks @ematipico! - Reduced the amount of polyfills provided by Astro. Astro will no longer provide (no-op) polyfills for several web apis such as HTMLElement, Image or Document. If you need access to those APIs on the server, we recommend using more proper polyfills available on npm.

  • #8169 e79e3779d Thanks @bluwy! - Remove pre-shiki v0.14 theme names for compatibility. Please rename to the new theme names to migrate:

    • material-darker -> material-theme-darker
    • material-default -> material-theme
    • material-lighter -> material-theme-lighter
    • material-ocean -> material-theme-ocean
    • material-palenight -> material-theme-palenight

  • #8188 96beb883a Thanks @ematipico! - Update tsconfig.json presets with moduleResolution: 'bundler' and other new options from TypeScript 5.0. Astro now assumes that you use TypeScript 5.0 (March 2023), or that your editor includes it, ex: VS Code 1.77

  • #8188 997a0db8a Thanks @ematipico! - The astro check command now requires an external package @astrojs/check and an install of typescript in your project. This was done in order to make the main astro package smaller and give more flexibility to users in regard to the version of TypeScript they use.

  • #8188 80f1494cd Thanks @ematipico! - The build.split and build.excludeMiddleware configuration options are deprecated and have been replaced by options in the adapter config.

    If your config includes the build.excludeMiddleware option, replace it with edgeMiddleware in your adapter options:

    diff
    import { defineConfig } from "astro/config";
import vercel from "@astrojs/vercel/serverless";

export default defineConfig({
     build: {
-        excludeMiddleware: true
     },
     adapter: vercel({
+        edgeMiddleware: true
     }),
});

    If your config includes the build.split option, replace it with functionPerRoute in your adapter options:

    diff
    import { defineConfig } from "astro/config";
import vercel from "@astrojs/vercel/serverless";

export default defineConfig({
     build: {
-        split: true
     },
     adapter: vercel({
+        functionPerRoute: true
     }),
});

  • #8188 0f0625504 Thanks @ematipico! - Lowercase names for endpoint functions are now deprecated.

    Rename functions to their uppercase equivalent:

    diff
    - export function get() {
+ export function GET() {
    return new Response(JSON.stringify({ "title": "Bob's blog" }));
}

- export function post() {
+ export function POST() {
    return new Response(JSON.stringify({ "title": "Bob's blog" }));
}

- export function put() {
+ export function PUT() {
    return new Response(JSON.stringify({ "title": "Bob's blog" }));
}

- export function all() {
+ export function ALL() {
    return new Response(JSON.stringify({ "title": "Bob's blog" }));
}

// you can use the whole word "DELETE"
- export function del() {
+ export function DELETE() {
    return new Response(JSON.stringify({ "title": "Bob's blog" }));
}

  • #8188 e1ae56e72 Thanks @ematipico! - Astro.cookies.get(key) returns undefined if cookie doesn't exist

    With this change, Astro.cookies.get(key) no longer always returns a AstroCookie object. Instead it now returns undefined if the cookie does not exist.

    You should update your code if you assume that all calls to get() return a value. When using with has() you still need to assert the value, like so:

    astro
    ---
if (Astro.cookies.has(id)) {
  const id = Astro.cookies.get(id)!;
}
---

  • #8188 f32d093a2 Thanks @ematipico! - The property compressHTML is now true by default. Setting this value to true is no longer required.

    If you do not want to minify your HTML output, you must set this value to false in astro.config.mjs.

    diff
    import {defineConfig} from "astro/config";
export default defineConfig({
+  compressHTML: false
})

  • #8188 f01eb585e Thanks @ematipico! - Astro's default port when running the dev or preview server is now 4321.

    This will reduce conflicts with ports used by other tools.

  • #7921 b76c166bd Thanks @Princesseuh! - astro:assets is now enabled by default. If you were previously using the experimental.assets flag, please remove it from your config. Also note that the previous @astrojs/image integration is incompatible, and must be removed.

    This also brings two important changes to using images in Astro:

    • New ESM shape: importing an image will now return an object with different properties describing the image such as its path, format and dimensions. This is a breaking change and may require you to update your existing images.
    • In Markdown, MDX, and Markdoc, the ![]() syntax will now resolve relative images located anywhere in your project in addition to remote images and images stored in the public/ folder. This notably unlocks storing images next to your content.

    Please see our existing Assets page in Docs for more information about using astro:assets.

  • #8188 32669cd47 Thanks @ematipico! - Remove MDX special components export handling

Minor Changes

  • #8188 cd2d7e769 Thanks @ematipico! - Introduced the concept of feature map. A feature map is a list of features that are built-in in Astro, and an Adapter can tell Astro if it can support it.

    ts
    import { AstroIntegration } from './astro';

function myIntegration(): AstroIntegration {
  return {
    name: 'astro-awesome-list',
    // new feature map
    supportedAstroFeatures: {
      hybridOutput: 'experimental',
      staticOutput: 'stable',
      serverOutput: 'stable',
      assets: {
        supportKind: 'stable',
        isSharpCompatible: false,
        isSquooshCompatible: false,
      },
    },
  };
}

  • #8218 44f7a2872 Thanks @matthewp! - View Transitions unflagged

    View Transition support in Astro is now unflagged. For those who have used the experimental feature you can remove the flag in your Astro config:

    diff
    import { defineConfig } from 'astro'

export default defineConfig({
-  experimental: {
-    viewTransitions: true,
-  }
})

    After removing this flag, please also consult the specific upgrade to v3.0 advice as some API features have changed and you may have breaking changes with your existing view transitions.

    See the View Transitions guide to learn how to use the API.

  • #8101 ea7ff5177 Thanks @matthewp! - astro:namespace aliases for middleware and components

    This adds aliases of astro:middleware and astro:components for the middleware and components modules. This is to make our documentation consistent between are various modules, where some are virtual modules and others are not. Going forward new built-in modules will use this namespace.

  • #8188 036388f66 Thanks @ematipico! - Integrations can now log messages using Astro’s built-in logger.

    The logger is available to all hooks as an additional parameter:

    ts
    import { AstroIntegration } from './astro';

// integration.js
export function myIntegration(): AstroIntegration {
  return {
    name: 'my-integration',
    hooks: {
      'astro:config:done': ({ logger }) => {
        logger.info('Configure integration...');
      },
    },
  };
}

Patch Changes

  • #8217 c37632a20 Thanks @martrapp! - Specify data-astro-reload (no value) on an anchor element to force the browser to ignore view transitions and fall back to default loading.

    • Previously, class:list would occasionally not be merged the class prop when passed to Astro components. Now, class:list is always converted to a class prop (as a string value).
    • Previously, class:list diverged from clsx in a few edge cases. Now, class:list uses clsx directly.
      • class:list used to deduplicate matching values, but it no longer does
      • class:list used to sort individual values, but it no longer does
      • class:list used to support Set and other iterables, but it no longer does

  • #7778 d6b494376 Thanks @y-nk! - Added support for optimizing remote images from authorized sources when using astro:assets. This comes with two new parameters to specify which domains (image.domains) and host patterns (image.remotePatterns) are authorized for remote images.

    For example, the following configuration will only allow remote images from astro.build to be optimized:

    ts
    // astro.config.mjs
export default defineConfig({
  image: {
    domains: ['astro.build'],
  },

  • #7893 7bd1b86f8 Thanks @ematipico! - Implements a new scope style strategy called "attribute". When enabled, styles are applied using data-* attributes.

    The default value of scopedStyleStrategy is "attribute".

    If you want to use the previous behaviour, you have to use the "where" option:

    diff
    import { defineConfig } from 'astro/config';

export default defineConfig({
+    scopedStyleStrategy: 'where',
});

  • #7924 519a1c4e8 Thanks @matthewp! - Astro's JSX handling has been refactored with better support for each framework.

    Previously, Astro automatically scanned your components to determine which framework-specific transformations should be used. In practice, supporting advanced features like Fast Refresh with this approach proved difficult.

    Now, Astro determines which framework to use with include and exclude config options where you can specify files and folders on a per-framework basis. When using multiple JSX frameworks in the same project, users should manually control which files belong to each framework using the include and exclude options.

    js
    export default defineConfig({
  // The `include` config is only needed in projects that use multiple JSX frameworks;
  // if only using one no extra config is needed.
  integrations: [
    preact({
      include: ['**/preact/*'],
    }),
    react({
      include: ['**/react/*'],
    }),
    solid({
      include: ['**/solid/*'],
    }),
  ],
});

  • #7878 0f637c71e Thanks @bluwy! - The value of import.meta.env.BASE_URL, which is derived from the base option, will no longer have a trailing slash added by default or when trailingSlash: "ignore" is set. The existing behavior of base in combination with trailingSlash: "always" or trailingSlash: "never" is unchanged.

    If your base already has a trailing slash, no change is needed.

    If your base does not have a trailing slash, add one to preserve the previous behaviour:

    diff
    // astro.config.mjs
- base: 'my-base',
+ base: 'my-base/',

Minor Changes

  • #8012 866ed4098 Thanks @ematipico! - Add a new astro/errors module. Developers can import AstroUserError, and provide a message and an optional hint

Patch Changes

3.0.0-beta.0

Major Changes

  • 1eae2e3f7 Thanks @Princesseuh! - Remove support for Node 16. The lowest supported version by Astro and all integrations is now v18.14.1. As a reminder, Node 16 will be deprecated on the 11th September 2023.

  • 76ddef19c Thanks @Princesseuh! - Removed automatic flattening of getStaticPaths result. .flatMap and .flat should now be used to ensure that you're returning a flat array.

  • 3fdf509b2 Thanks @ematipico! - The build.split and build.excludeMiddleware configuration options are deprecated and have been replaced by options in the adapter config.

    If your config includes the build.excludeMiddleware option, replace it with edgeMiddleware in your adapter options:

    diff
    import { defineConfig } from "astro/config";
import netlify from "@astrojs/netlify/functions";

export default defineConfig({
     build: {
-        excludeMiddleware: true
     },
     adapter: netlify({
+        edgeMiddleware: true
     }),
});

    If your config includes the build.split option, replace it with functionPerRoute in your adapter options:

    diff
    import { defineConfig } from "astro/config";
import netlify from "@astrojs/netlify/functions";

export default defineConfig({
     build: {
-        split: true
     },
     adapter: netlify({
+        functionPerRoute: true
     }),
});

  • 2f951cd40 Thanks @Princesseuh! - Sharp is now the default image service used for astro:assets. If you would prefer to still use Squoosh, you can update your config with the following:

    ts
    import { defineConfig, squooshImageService } from 'astro/config';

// https://astro.build/config
export default defineConfig({
  image: {
    service: squooshImageService(),
  },
});

    However, not only do we recommend using Sharp as it is faster and more reliable, it is also highly likely that the Squoosh service will be removed in a future release.

  • c022a4217 Thanks @Princesseuh! - When using an adapter that supports neither Squoosh or Sharp, Astro will now automatically use an image service that does not support processing, but still provides the other benefits of astro:assets such as enforcing alt, no CLS etc to users

  • 67becaa58 Thanks @ematipico! - Removed support for old syntax of the API routes.

  • dfc2d93e3 Thanks @bluwy! - Remove MDX plugin re-ordering hack

  • 3dc1ca2fa Thanks @Princesseuh! - Reduced the amount of polyfills provided by Astro. Astro will no longer provide (no-op) polyfills for several web apis such as HTMLElement, Image or Document. If you need access to those APIs on the server, we recommend using more proper polyfills available on npm.

  • 1be84dfee Thanks @Princesseuh! - Update tsconfig.json presets with moduleResolution: 'bundler' and other new options from TypeScript 5.0. Astro now assumes that you use TypeScript 5.0 (March 2023), or that your editor includes it, ex: VS Code 1.77

  • 35f01df79 Thanks @Princesseuh! - The astro check command now requires an external package @astrojs/check and an install of typescript in your project. This was done in order to make the main astro package smaller and give more flexibility to users in regard to the version of TypeScript they use.

  • 3fdf509b2 Thanks @ematipico! - The build.split and build.excludeMiddleware configuration options are deprecated and have been replaced by options in the adapter config.

    If your config includes the build.excludeMiddleware option, replace it with edgeMiddleware in your adapter options:

    diff
    import { defineConfig } from "astro/config";
import vercel from "@astrojs/vercel/serverless";

export default defineConfig({
     build: {
-        excludeMiddleware: true
     },
     adapter: vercel({
+        edgeMiddleware: true
     }),
});

    If your config includes the build.split option, replace it with functionPerRoute in your adapter options:

    diff
    import { defineConfig } from "astro/config";
import vercel from "@astrojs/vercel/serverless";

export default defineConfig({
     build: {
-        split: true
     },
     adapter: vercel({
+        functionPerRoute: true
     }),
});

  • 78de801f2 Thanks @ematipico! - Lowercase names for endpoint functions are now deprecated.

    Rename functions to their uppercase equivalent:

    diff
    - export function get() {
+ export function GET() {
    return new Response(JSON.stringify({ "title": "Bob's blog" }));
}

- export function post() {
+ export function POST() {
    return new Response(JSON.stringify({ "title": "Bob's blog" }));
}

- export function put() {
+ export function PUT() {
    return new Response(JSON.stringify({ "title": "Bob's blog" }));
}

- export function all() {
+ export function ALL() {
    return new Response(JSON.stringify({ "title": "Bob's blog" }));
}

// you can use the whole word "DELETE"
- export function del() {
+ export function DELETE() {
    return new Response(JSON.stringify({ "title": "Bob's blog" }));
}

  • 59d6e569f Thanks @matthewp! - Astro.cookies.get(key) returns undefined if cookie doesn't exist

    With this change, Astro.cookies.get(key) no longer always returns a AstroCookie object. Instead it now returns undefined if the cookie does not exist.

    You should update your code if you assume that all calls to get() return a value. When using with has() you still need to assert the value, like so:

    astro
    ---
if (Astro.cookies.has(id)) {
  const id = Astro.cookies.get(id)!;
}
---

  • 7723c4cc9 Thanks @ematipico! - The property compressHTML is now true by default. Setting this value to true is no longer required.

    If you do not want to minify your HTML output, you must set this value to false in astro.config.mjs.

    diff
    import {defineConfig} from "astro/config";
export default defineConfig({
+  compressHTML: false
})

  • fb5cd6b56 Thanks @ematipico! - Astro's default port when running the dev or preview server is now 4321.

    This will reduce conflicts with ports used by other tools.

  • 631b9c410 Thanks @bluwy! - Remove MDX special components export handling

Minor Changes

  • 9b4f70a62 Thanks @ematipico! - Introduced the concept of feature map. A feature map is a list of features that are built-in in Astro, and an Adapter can tell Astro if it can support it.

    ts
    import { AstroIntegration } from './astro';

function myIntegration(): AstroIntegration {
  return {
    name: 'astro-awesome-list',
    // new feature map
    supportedAstroFeatures: {
      hybridOutput: 'experimental',
      staticOutput: 'stable',
      serverOutput: 'stable',
      assets: {
        supportKind: 'stable',
        isSharpCompatible: false,
        isSquooshCompatible: false,
      },
    },
  };
}

  • bc37331d8 Thanks @ematipico! - Integrations can now log messages using Astro’s built-in logger.

    The logger is available to all hooks as an additional parameter:

    ts
    import { AstroIntegration } from './astro';

// integration.js
export function myIntegration(): AstroIntegration {
  return {
    name: 'my-integration',
    hooks: {
      'astro:config:done': ({ logger }) => {
        logger.info('Configure integration...');
      },
    },
  };
}
