76db01dThanks @rodrigosdev! - Fixes config validation for omittedintegrationsfields with newer Zod versions. -
#16535
7df0fe4Thanks @rururux! - Fixed an issue where a warning was displayed when theserverproperty was missing during config validation, even though it is not required. -
#16534
5cf6c51Thanks @matthewp! - Fixes compatibility with Zod 4.4.0 for theserverconfig property and error formatting
astro@6.2.0
Minor Changes
-
#16187
fe58071Thanks @gllmt! - Adds awaitUntiloption to theRenderOptionsso that adapters can forward runtime background-task hooks to Astro.When provided by an adapter, runtime cache providers receive
context.waitUntilin
CacheProvider.onRequest(), which allows background cache work such as stale-while-revalidate
without blocking the response. The Cloudflare adapter now forwards
ExecutionContext.waitUntilto this API. -
#16290
a49637aThanks @ViVaLaDaniel! - Ensures thatserver.allowedHosts(andvite.preview.allowedHosts) configuration is respected when usingastro previewwith the@astrojs/cloudflareadapter. This improves security by preventing DNS rebinding attacks when previewing Cloudflare builds locally. -
#15725
4108ec1Thanks @meyer! - Adds support for a new'jsx'value for thecompressHTMLoption. When set, whitespace is stripped using JSX whitespace rules instead of the default HTML compression strategy.// astro.config.mjs import { defineConfig } from 'astro/config'; export default defineConfig({ compressHTML: 'jsx', });
In JSX, whitespaces never matter, as such, no amount of indentation, or newlines will not affect the rendered output. For instance, the following code:
<div> <span>foo</span> <span>bar</span> </div>
will be rendered as
foobar, whereas with HTML whitespace rules, a space would be present between the words due to the newline and indentation between the tags. -
#16477
28fb3e1Thanks @ematipico! - Adds experimental support for configurable log handlers.This experimental feature provides better control over Astro's logging infrastructure by allowing users to replace the default console output with custom logging implementations (e.g., structured JSON). This is particularly useful for users using on-demand rendering and wishing to connect their log aggregation services, such as Kibana, Logstash, CloudWatch, Grafana, or Loki.
By default, Astro provides three built-in log handlers (
json,node, andconsole), but you can also create your own.JSON logging
JSON logging can be enabled via the CLI for the
build,dev, andsynccommands using theexperimentalJsonflag:// astro.config.mjs import { defineConfig, logHandlers } from 'astro/config'; export default defineConfig({ experimental: { logger: logHandlers.json({ pretty: true, level: 'warn', }), }, });
Custom logger
You can also create your own custom logger by implementing the correct interface:
// astro.config.mjs import { defineConfig } from 'astro/config'; export default defineConfig({ experimental: { logger: { entrypoint: '@org/custom-logger', }, }, });
// @org/custom-logger.js import type { AstroLoggerDestination, AstroLoggerMessage } from 'astro'; import { matchesLevel } from 'astor/logger'; function customLogger(level = 'info'): AstroLoggerDestination { return { write(message: AstroLoggerMessage) { if (matchesLevel(message.level, level)) { // write message somewhere } }, }; } export default customLogger;
For more information on enabling and using this feature in your project, see the Experimental Logger docs.
For a complete overview and to give feedback on this experimental API, see the Custom logger RFC.

#16333
0f7c3c8Thanks @florian-lefebvre! - Adds an experimental flagsvgOptimizerthat enables automatic optimization of your SVG components using the provided optimizer. This supersedes thesvgoexperimental flag, which is now removed.When enabled, your imported SVG files used as components will be optimized for smaller file sizes and better performance while maintaining visual quality. This can significantly reduce the size of your SVG assets by removing unnecessary metadata, comments, and redundant code.
Astro ships with a SVGO based optimizer, but any can be used.
To enable this feature, add the experimental flag in your Astro config and remove
svgoif it was enabled:// astro.config.mjs -import { defineConfig } from "astro/config"; +import { defineConfig, svgoOptimizer } from "astro/config"; export default defineConfig({ + experimental: { + svgOptimizer: svgoOptimizer() - svgo: true + } });
For more information on enabling and using this feature in your project, see the experimental SVG optimization docs.

#16302
f6f8e80Thanks @florian-lefebvre! - Adds a newexperimental_getFontFileURL()method to resolve font file URLs when using the Fonts APIThe
fontDataobject exported fromastro:assetswas introduced to provide low-level access to font family data for advanced usage. One of the goals of this API was to be able to resolve buffers using URLs. However, it turned out to be impractical, especially during prerendering.Astro now exports a new
experimental_getFontFileURL()helper function fromastro:assetsto resolve font file URLs fromfontData. For example, when using satori to generate Open Graph images:// src/pages/og.png.ts import type { APIRoute } from "astro"; -import { fontData } from "astro:assets"; +import { fontData, experimental_getFontFileURL } from "astro:assets"; -import { outDir } from "astro:config/server"; -import { readFile } from "node:fs/promises"; import satori from "satori"; import { html } from "satori-html"; import sharp from "sharp"; export const GET: APIRoute = async (context) => { const fontPath = fontData["--font-roboto"][0]?.src[0]?.url; if (fontPath === undefined) { throw new Error("Cannot find the font path."); } - const data = import.meta.env.DEV - ? await fetch(new URL(fontPath, context.url.origin)).then(async (res) => res.arrayBuffer()) - : await readFile(new URL(`.${fontPath}`, outDir)); + const url = experimental_getFontFileURL(fontPath, context.url); + const data = await fetch(url).then((res) => res.arrayBuffer()); const svg = await satori( html`<div style="color: black;">hello, world</div>`, { width: 600, height: 400, fonts: [ { name: "Roboto", data, weight: 400, style: "normal", }, ], }, ); const pngBuffer = await sharp(Buffer.from(svg)) .resize(600, 400) .png() .toBuffer(); return new Response(new Uint8Array(pngBuffer), { headers: { "Content-Type": "image/png", }, }); };See the Fonts API documentation for more information.

#16462
c30a778Thanks @Princesseuh! - Replaces the Go compiler with a Rust-based version.The Rust-based Astro compiler (
@astrojs/compiler-rs) is now the default compiler. This new compiler is faster and more reliable, leading to faster build times and iteration cycles during development.This new compiler is more strict regarding invalid syntax. For example, unclosed HTML tags will now throw an error instead of being ignored. It also does not attempt to correct semantically invalid HTML anymore, instead leaving it to the browser to handle, similar to other tools or
document.write()in JavaScript.The previous Go-based compiler has been removed, along with the
experimental.rustCompilerflag used to opt into the Rust compiler. If you were settingexperimental.rustCompilerin yourastro.config.mjs, you can now remove it. No other action is required.
