Patch Changes

#3534 703fab0 Thanks @HiDeoo! - Fixes support for running builds when npx is unavailable.

Previously, Starlight would spawn a process to run the Pagefind search indexing binary using npx. On platforms where npx isn’t available, this could cause issues. Starlight now runs Pagefind using its Node.js API to avoid a separate process. As a side effect, you may notice that logging during builds is now less verbose.
#3656 a0e6368 Thanks @delucis! - Fixes several edge cases in highlighting the current page heading in Starlight’s table of contents
#3663 00cbf00 Thanks @lines-of-codes! - Adds Thai language support
#3658 ac79329 Thanks @delucis! - Avoids adding redundant aria-current="false" attributes to sidebar entries

Minor Changes

#14932 b19d816 Thanks @patrickarlt! - Adds support for returning a Promise from the parser() option of the file() loader

This enables you to run asynchronous code such as fetching remote data or using async parsers when loading files with the Content Layer API.

For example:

import { defineCollection } from 'astro:content';
import { file } from 'astro/loaders';

const blog = defineCollection({
  loader: file('src/data/blog.json', {
    parser: async (text) => {
      const data = JSON.parse(text);

      // Perform async operations like fetching additional data
      const enrichedData = await fetch(`https://api.example.com/enrich`, {
        method: 'POST',
        body: JSON.stringify(data),
      }).then((res) => res.json());

      return enrichedData;
    },
  }),
});

export const collections = { blog };

See the parser() reference documentation for more information.

#15171 f220726 Thanks @mark-ignacio! - Adds a new, optional kernel configuration option to select a resize algorithm in the Sharp image service

By default, Sharp resizes images with the lanczos3 kernel. This new config option allows you to set the default resizing algorithm to any resizing option supported by Sharp (e.g. linear, mks2021).

Kernel selection can produce quite noticeable differences depending on various characteristics of the source image - especially drawn art - so changing the kernel gives you more control over the appearance of images on your site:
```
export default defineConfig({
  image: {
    service: {
      entrypoint: 'astro/assets/services/sharp',
      config: {
        kernel: "mks2021"
      }
  }
})
```
This selection will apply to all images on your site, and is not yet configurable on a per-image basis. For more information, see Sharps documentation on resizing images.
#15063 08e0fd7 Thanks @jmortlock! - Adds a new partitioned option when setting a cookie to allow creating partitioned cookies.

Partitioned cookies can only be read within the context of the top-level site on which they were set. This allows cross-site tracking to be blocked, while still enabling legitimate uses of third-party cookies.

You can create a partitioned cookie by passing partitioned: true when setting a cookie. Note that partitioned cookies must also be set with secure: true:
```
Astro.cookies.set('my-cookie', 'value', {
  partitioned: true,
  secure: true,
});
```
For more information, see the AstroCookieSetOptions API reference.
#15022 f1fce0e Thanks @ascorbic! - Adds a new retainBody option to the glob() loader to allow reducing the size of the data store.

Currently, the glob() loader stores the raw body of each content file in the entry, in addition to the rendered HTML.

The retainBody option defaults to true, but you can set it to false to prevent the raw body of content files from being stored in the data store. This significantly reduces the deployed size of the data store and helps avoid hitting size limits for sites with very large collections.

The rendered body will still be available in the entry.rendered.html property for markdown files, and the entry.filePath property will still point to the original file.
```
import { defineCollection } from 'astro:content';
import { glob } from 'astro/loaders';

const blog = defineCollection({
  loader: glob({
    pattern: '**/*.md',
    base: './src/content/blog',
    retainBody: false,
  }),
});
```
When retainBody is false, entry.body will be undefined instead of containing the raw file contents.
#15153 928529f Thanks @jcayzac! - Adds a new background property to the <Image /> component.

This optional property lets you pass a background color to flatten the image with. By default, Sharp uses a black background when flattening an image that is being converted to a format that does not support transparency (e.g. jpeg). Providing a value for background on an <Image /> component, or passing it to the getImage() helper, will flatten images using that color instead.

This is especially useful when the requested output format doesn't support an alpha channel (e.g. jpeg) and can't support transparent backgrounds.
```
---
import { Image } from 'astro:assets';
---

<Image
  src="/transparent.png"
  alt="A JPEG with a white background!"
  format="jpeg"
  background="#ffffff"
/>
```
See more about this new property in the image reference docs
#15015 54f6006 Thanks @tony! - Adds optional placement config option for the dev toolbar.

You can now configure the default toolbar position ('bottom-left', 'bottom-center', or 'bottom-right') via devToolbar.placement in your Astro config. This option is helpful for sites with UI elements (chat widgets, cookie banners) that are consistently obscured by the toolbar in the dev environment.

You can set a project default that is consistent across environments (e.g. dev machines, browser instances, team members):
```
// astro.config.mjs
export default defineConfig({
  devToolbar: {
    placement: 'bottom-left',
  },
});
```
User preferences from the toolbar UI (stored in localStorage) still take priority, so this setting can be overridden in individual situations as necessary.

#15213 c775fce Thanks @florian-lefebvre! - BREAKING CHANGE to the experimental Fonts API only

Updates how the local provider must be used when using the experimental Fonts API

Previously, there were 2 kinds of font providers: remote and local.

Font providers are now unified. If you are using the local provider, the process for configuring local fonts must be updated:

-import { defineConfig } from "astro/config";
+import { defineConfig, fontProviders } from "astro/config";

export default defineConfig({
    experimental: {
        fonts: [{
            name: "Custom",
            cssVariable: "--font-custom",
-            provider: "local",
+            provider: fontProviders.local(),
+            options: {
            variants: [
                {
                    weight: 400,
                    style: "normal",
                    src: ["./src/assets/fonts/custom-400.woff2"]
                },
                {
                    weight: 700,
                    style: "normal",
                    src: ["./src/assets/fonts/custom-700.woff2"]
                }
                // ...
            ]
+            }
        }]
    }
});

Once configured, there is no change to using local fonts in your project. However, you should inspect your deployed site to confirm that your new font configuration is being applied.

See the experimental Fonts API docs for more information.

#15213 c775fce Thanks @florian-lefebvre! - Exposes root on FontProvider init() context

When building a custom FontProvider for the experimental Fonts API, the init() method receives a context. This context now exposes a root URL, useful for resolving local files:
```
import type { FontProvider } from "astro";

export function registryFontProvider(): FontProvider {
  return {
    // ...
-    init: async ({ storage }) => {
+    init: async ({ storage, root }) => {
        // ...
    },
  };
}
```

#15182 cb60ee1 Thanks @florian-lefebvre! - Adds a new getFontBuffer() method to retrieve font file buffers when using the experimental Fonts API

The getFontData() helper function from astro:assets was introduced in 5.14.0 to provide access to font family data for use outside of Astro. One of the goals of this API was to be able to retrieve buffers using URLs.

However, it turned out to be impactical and even impossible during prerendering.

Astro now exports a new getFontBuffer() helper function from astro:assets to retrieve font file buffers from URL returned by getFontData(). For example, when using satori to generate OpenGraph images:

// src/pages/og.png.ts

import type{ APIRoute } from "astro"
-import { getFontData } from "astro:assets"
+import { getFontData, getFontBuffer } from "astro:assets"
import satori from "satori"

export const GET: APIRoute = (context) => {
  const data = getFontData("--font-roboto")

  const svg = await satori(
    <div style={{ color: "black" }}>hello, world</div>,
    {
      width: 600,
      height: 400,
      fonts: [
        {
          name: "Roboto",
-          data: await fetch(new URL(data[0].src[0].url, context.url.origin)).then(res => res.arrayBuffer()),
+          data: await getFontBuffer(data[0].src[0].url),
          weight: 400,
          style: "normal",
        },
      ],
    },
  )

  // ...
}

#15175 47ae148 Thanks @florian-lefebvre! - Allows experimental Font providers to specify family options

Previously, an Astro FontProvider could only accept options at the provider level when called. That could result in weird data structures for family-specific options.

Astro FontProviders can now declare family-specific options, by specifying a generic:

// font-provider.ts
import type { FontProvider } from "astro";
import { retrieveFonts, type Fonts } from "./utils.js",

interface Config {
  token: string;
}

+interface FamilyOptions {
+    minimal?: boolean;
+}

-export function registryFontProvider(config: Config): FontProvider {
+export function registryFontProvider(config: Config): FontProvider<FamilyOptions> {
  let data: Fonts = {}

  return {
    name: "registry",
    config,
    init: async () => {
      data = await retrieveFonts(token);
    },
    listFonts: () => {
      return Object.keys(data);
    },
-    resolveFont: ({ familyName, ...rest }) => {
+    // options is typed as FamilyOptions
+    resolveFont: ({ familyName, options, ...rest }) => {
      const fonts = data[familyName];
      if (fonts) {
        return { fonts };
      }
      return undefined;
    },
  };
}

Once the font provider is registered in the Astro config, types are automatically inferred:

// astro.config.ts
import { defineConfig } from "astro/config";
import { registryFontProvider } from "./font-provider";

export default defineConfig({
    experimental: {
        fonts: [{
            provider: registryFontProvider({
              token: "..."
            }),
            name: "Custom",
            cssVariable: "--font-custom",
+            options: {
+                minimal: true
+            }
        }]
    }
});

#15175 47ae148 Thanks @florian-lefebvre! - BREAKING CHANGE to the experimental Fonts API only

Updates how options are passed to the Google and Google Icons font providers when using the experimental Fonts API

Previously, the Google and Google Icons font providers accepted options that were specific to given font families.

These options must now be set using the options property instead. For example using the Google provider:

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

export default defineConfig({
    experimental: {
        fonts: [{
            name: 'Inter',
            cssVariable: '--astro-font-inter',
            weights: ['300 900'],
-            provider: fontProviders.google({
-                experimental: {
-                    variableAxis: {
-                        Inter: { opsz: ['14..32'] }
-                    }
-                }
-            }),
+            provider: fontProviders.google(),
+            options: {
+                experimental: {
+                    variableAxis: { opsz: ['14..32'] }
+                }
+            }
        }]
    }
})

#15200 c0595b3 Thanks @florian-lefebvre! - BREAKING CHANGE to the experimental Fonts API only

Removes getFontData() exported from astro:assets with fontData when using the experimental Fonts API

Accessing font data can be useful for advanced use cases, such as generating meta tags or Open Graph images. Before, we exposed a getFontData() helper function to retrieve the font data for a given cssVariable. That was however limiting for programmatic usages that need to access all font data.

The getFontData() helper function is removed and replaced by a new fontData object:
```
-import { getFontData } from "astro:assets";
-const data = getFontData("--font-roboto")

+import { fontData } from "astro:assets";
+const data = fontData["--font-roboto"]
```
We may reintroduce getFontData() later on for a more friendly DX, based on your feedback.
#15254 8d84b30 Thanks @lamalex! - Fixes CSS assetsPrefix with remote URLs incorrectly prepending a forward slash

When using build.assetsPrefix with a remote URL (e.g., https://cdn.example.com) for CSS assets, the generated <link> elements were incorrectly getting a / prepended to the full URL, resulting in invalid URLs like /https://cdn.example.com/assets/style.css.
