Fix incremental build serving cached HTML with stale CSS filenames after stylesheet-only edits by astrobot-houston · Pull Request #17705 · withastro/astro

astrobot-houston · 2026-08-15T04:08:30Z

Changes

CSS modules in the prerender build have empty code — Vite extracts their content into separate assets, leaving the module's code as "". Because hashModules() was skipping modules with no code, CSS edits never changed the dependency hash and canSkip() incorrectly returned true, restoring cached HTML that referenced the old, now-missing _astro/*.css filename.
When a module's code is empty and its ID matches CSS_LANGS_RE, hashModules() now reads the source file from disk and includes its contents in the hash. CSS edits now produce a different dependency hash, causing affected pages to re-render with the correct stylesheet reference.

Testing

Added two unit tests in plugin-incremental.test.ts under CSS modules (#17704): one that asserts the hash changes when the CSS file is modified on disk, and one that asserts the hash is stable when the file is unchanged.

Docs

No docs update needed — this fixes a bug in experimental.incrementalBuild, which is not yet documented beyond the config reference.

…ale cache hits (#17704)\n\nCSS modules have empty `code` in Vite's prerender bundle because their\ncontent is extracted into separate assets. The incremental build's\n`hashModules()` was hashing only the (empty) bundle code, so CSS edits\nnever changed the dependency hash and cached pages kept referencing\nstale CSS filenames.\n\nWhen a module's code is empty and its ID matches a CSS file pattern,\nread the source file from disk and hash its contents instead."

An entry without an explicit `q=` now correctly counts as quality `1.0` (per RFC 7231) and an entry with `q=0` is treated as not acceptable, so the highest-quality locale is selected regardless of header order. - [#17757](withastro/astro#17757) [`660991c`](withastro/astro@660991c) Thanks [@astro-factory](https://github.com/apps/astro-factory)! - Fixes build errors showing wrong file location, missing line:col, and misleading hints when a plugin error (e.g. from MDX) is wrapped by Vite's build error - [#17783](withastro/astro#17783) [`60b14ff`](withastro/astro@60b14ff) Thanks [@matthewp](https://github.com/matthewp)! - Fixes a type error when passing an image from a content collection `image()` schema to a component or `<Image />`. The schema returned by `image()` was missing the `apng` format, so it no longer matched the type of an imported image. - [#17664](withastro/astro#17664) [`d483125`](withastro/astro@d483125) Thanks [@astrobot-houston](https://github.com/astrobot-houston)! - Fixes an issue where Astro CSP support didn't correctly handle cases `"unsafe-inline"` resource. Now when `"unsafe-inline"`, Astro won't emit hashes for the directive specified. - [#17810](withastro/astro#17810) [`0fc5f65`](withastro/astro@0fc5f65) Thanks [@florian-lefebvre](https://github.com/florian-lefebvre)! - Fixes a regression in the content collections that could cause images to not be resolved - [#17781](withastro/astro#17781) [`aa33b44`](withastro/astro@aa33b44) Thanks [@matthewp](https://github.com/matthewp)! - Fixes `memoryCache()` storing responses that set cookies through `Astro.cookies` or `Astro.session` - [#17787](withastro/astro#17787) [`6661fbe`](withastro/astro@6661fbe) Thanks [@astro-factory](https://github.com/apps/astro-factory)! - Fixes `server:defer` crashing the dev server with "undefined is not a function" when a deferred component imports from `astro:i18n` - [#17750](withastro/astro#17750) [`dd0e3ac`](withastro/astro@dd0e3ac) Thanks [@dobrodob](https://github.com/dobrodob)! - Fixes a regression where `transition:persist` stopped working for `<audio>` and `<video>` elements. - [#17774](withastro/astro#17774) [`fe1d16d`](withastro/astro@fe1d16d) Thanks [@astro-factory](https://github.com/apps/astro-factory)! - Adds support for importing `.apng` files as image metadata for use with standard `<img>` elements.
