#15174 37ab65a Thanks @florian-lefebvre! - Adds Google Icons to built-in font providers

To start using it, access it on fontProviders:

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

export default defineConfig({
  experimental: {
    fonts: [
      {
        name: 'Material Symbols Outlined',
        provider: fontProviders.googleicons(),
        cssVariable: '--font-material',
      },
    ],
  },
});

#15150 a77c4f4 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.

#15130 9b726c4 Thanks @florian-lefebvre! - BREAKING CHANGE to the experimental Fonts API only

Changes how font providers are implemented with updates to the FontProvider type

This is an implementation detail that changes how font providers are created. This process allows Astro to take more control rather than relying directly on unifont types. All of Astro's built-in font providers have been updated to reflect this new type, and can be configured as before. However, using third-party unifont providers that rely on unifont types will require an update to your project code.

Previously, an Astro FontProvider was made of a config and a runtime part. It relied directly on unifont types, which allowed a simple configuration for third-party unifont providers, but also coupled Astro's implementation to unifont, which was limiting.

Astro's font provider implementation is now only made of a config part with dedicated hooks. This allows for the separation of config and runtime, but requires you to create a font provider object in order to use custom font providers (e.g. third-party unifont providers, or private font registeries).

If you were using a 3rd-party unifont font provider, you will now need to write an Astro FontProvider using it under the hood. For example:

// astro.config.ts
import { defineConfig } from "astro/config";
import { acmeProvider, type AcmeOptions } from '@acme/unifont-provider'
+import type { FontProvider } from "astro";
+import type { InitializedProvider } from 'unifont';

+function acme(config?: AcmeOptions): FontProvider {
+	const provider = acmeProvider(config);
+	let initializedProvider: InitializedProvider | undefined;
+	return {
+		name: provider._name,
+		config,
+		async init(context) {
+			initializedProvider = await provider(context);
+		},
+		async resolveFont({ familyName, ...rest }) {
+			return await initializedProvider?.resolveFont(familyName, rest);
+		},
+		async listFonts() {
+			return await initializedProvider?.listFonts?.();
+		},
+	};
+}

export default defineConfig({
    experimental: {
        fonts: [{
-            provider: acmeProvider({ /* ... */ }),
+            provider: acme({ /* ... */ }),
            name: "Material Symbols Outlined",
            cssVariable: "--font-material"
        }]
    }
});

#15118 cfa382b Thanks @florian-lefebvre! - BREAKING CHANGE to the experimental Fonts API only

Removes the defineAstroFontProvider() type helper.

If you are building a custom font provider, remove any occurrence of defineAstroFontProvider() and use the FontProvider type instead:

-import { defineAstroFontProvider } from 'astro/config';

-export function myProvider() {
-    return defineAstroFontProvider({
-        entrypoint: new URL('./implementation.js', import.meta.url)
-    });
-};

+import type { FontProvider } from 'astro';

+export function myProvider(): FontProvider {
+    return {
+        entrypoint: new URL('./implementation.js', import.meta.url)
+    },
+}

#15117 b1e8e32 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.

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']
        }]
    }
})
