fix(assets): resolve Picture TDZ error when combined with content render() by Desel72 · Pull Request #16171 · withastro/astro

Desel72 · 2026-03-31T19:56:40Z

Introduce an internal virtual module (virtual:astro-get-image) that exports only getImage and imageConfig without any Astro component references. The content runtime now imports from this narrower module instead of astro:assets, breaking the circular initialization dependency that caused a TDZ ReferenceError when prerendered pages using <Picture> were bundled in the same chunk as content collection render() calls.

Closes #16036

Changes

Added a new internal virtual module virtual:astro-get-image in packages/astro/src/assets/consts.ts that exports only getImage and imageConfig — no Image, Picture, or Font component references.
Extended the astro:assets Vite plugin in packages/astro/src/assets/vite-plugin-assets.ts to resolve and load the new virtual module.
Changed packages/astro/src/content/runtime.ts to import getImage from virtual:astro-get-image instead of astro:assets, avoiding the TDZ caused by Rollup eagerly referencing $$Picture in the namespace object before its declaration is initialized.
Uses virtual: prefix (like existing virtual:image-service) rather than astro: prefix to keep this as an internal module and avoid exposing new public API surface.

Testing

Added a regression test (content-collection-picture-render.test.js) with a fixture that reproduces the exact scenario:

A prerendered page using <Picture> from astro:assets
A content collection page using getStaticPaths() + render(entry) with images in markdown body

Without the fix, astro build fails with:
ReferenceError: Cannot access '$$Picture' before initialization

With the fix, the build succeeds and all 4 test assertions pass. Existing related test suites also pass with zero regressions:

content-collection-tla-svg.test.js (3/3)
content-collections-render.test.js (13/13)
core-image-picture-emit-file.test.js (6/6)
units/content-collections/image-references.test.js (9/9)

Docs

No docs changes needed. This is a bug fix for an internal module resolution issue — no user-facing API changes.

Use colon separator (virtual:astro:*) instead of hyphen so the module matches existing optimizeDeps.exclude patterns in both Astro core and the Cloudflare adapter. The hyphenated name was not excluded from Vite's dependency optimizer, causing esbuild to fail resolving it.

We must add this module to dev-only.d.ts, so that we don't need the ts directive

@Desel72 can you address this comment please?

@Desel72 you need to address Ema's feedback: #16171 (comment)

travisbreaks

Circular dependency causing TDZ errors is a nasty class of bug. The virtual module approach is a reasonable solution. A few things:

Virtual module boundary durability: The fix introduces `virtual:astro:get-image` to break the cycle. Future imports could re-introduce it if someone imports from `assets/consts.ts` in a path that also touches `content/runtime.ts`. A comment in the virtual module entry point warning about this would help prevent regression.
The @ts-expect-error question: ematipico's feedback about adding proper TS definitions is the right call. Virtual modules should have type declarations (`declare module "virtual:astro:get-image"`) so the `@ts-expect-error` isn't needed. This is a pattern Astro already uses for other virtual modules.
Test coverage: Does the test reproduce the exact bundling condition (Picture + content render() in the same chunk)? TDZ errors are sensitive to chunk splitting heuristics, so the test should ideally force co-location rather than relying on the current bundler behavior.

Good fix for a tricky problem. The TS definitions point from ematipico would make this merge-ready.

Two issues caused this: 1. The cf-externals plugin set top-level ssr.noExternal = true, which caused vitefu's crawlFrameworkPkgs to return an empty noExternal list (it assumed everything was already noExternal). This only applied to the ssr environment in Vite 6, leaving the prerender environment without the needed noExternal entries. 2. The createNodePrerenderPlugin disabled dep optimization entirely for the prerender environment (noDiscovery: true, include: []). The fix removes ssr.noExternal = true from cf-externals, removes the dep optimization override, and has @astrojs/svelte use crawlFrameworkPkgs to discover svelte packages and add them to resolve.noExternal for all server environments via configEnvironment. * add changeset * fix: use fileURLToPath for cross-platform root path * test: add response body to assertion error for CI debugging * fix: rename fake-svelte-pkg/dist to src to avoid .gitignore exclusion * [ci] format * fix: avoid full-reload in scss modules (#14924) * fix: avoid full-reload in scss modules * fix: improve regex * fix: ci * test: add test for modules * fix(hmr): prevent full-reload for SCSS/CSS module changes SCSS and CSS module file changes were triggering unnecessary full page reloads during development instead of applying HMR updates. This broke the developer experience by losing component state and scroll position on every style edit. Root cause: In the `astro:hmr-reload` Vite plugin, style files (CSS, SCSS, SASS, LESS, etc.) in the SSR module graph were correctly skipped via a regex check, but the handler returned `undefined` instead of an empty array. In Vite 6, returning `undefined` from a `hotUpdate` hook means "I didn't handle this", causing Vite to propagate through the SSR module graph to `.astro` importers. Since `.astro` pages have no HMR boundary, this triggered a full page reload. Changes to `vite-plugin-hmr-reload`: - Extract `isStyleModule()` helper that checks both `mod.file` and `mod.id` (stripping query params like `?inline`, `?used`) against the style extension regex. This correctly identifies all style-related modules including CSS module variants. - Return `[]` (empty array) when only style modules were encountered in the SSR environment. This tells Vite "handled, nothing to update in SSR", preventing the propagation chain that caused full reloads. The client environment handles CSS HMR natively through framework-specific HMR boundaries (Preact, React, Vue, etc.). Changes to e2e test fixtures: - Update the SCSS module HMR test to use a Preact component with `client:load` instead of a pure server-rendered Astro page. This matches the real-world scenario from the original bug report (issue #14869) where Preact + SCSS modules triggered full reloads. CSS module HMR requires a client-side framework to re-render components with updated class name hashes — pure SSR pages cannot hot-update CSS module class names without a full reload. Closes #14869 * fix(hmr): clarify comment about CSS HMR working for all pages The previous comment suggested CSS HMR only worked through framework-specific boundaries. Vite's built-in style update mechanism handles it for all pages, with or without framework components (covered by the scss-external test).

Also propagate the real HTTP status from send's error object instead of always returning 500. * add changeset * update changeset wording * Use redirect: manual in Cloudflare image binding transform (#16320) * Use redirect: 'manual' in cloudflare image-binding-transform fetch * Fix unused parameter lint error * test: add unit test for dlv util (#16262) * fix: netrify image validation (#16027) * fix(netlify): enforce validation for remote image dimensions * test(netlify): add regression test for missing image dimensions * fix: astro.config.mjs file * feat: changeset * delete: unnecessary file * fix: refactor to use loadFixture and project test infrastructure * fix: update changeset * fix: changeset explanation and refactor test code * refactor(assets): move verifyOptions export to internal to avoid hydration regressions * [ci] format * Add nightly Semgrep security scanning workflow (#16205) Co-authored-by: Felix Schneider <[email protected]> Co-authored-by: Emanuele Stoppa <[email protected]> * ci: cron job semgrep (#16336) * Update github-actions (#16146) Co-authored-by: renovate[bot] <29139614+renovate[bot]@users.noreply.github.com> * [ci] release (#16314) Co-authored-by: github-actions[bot] <41898282+github-actions[bot]@users.noreply.github.com> * chore: add rule for detecting incorrect imports (#16343) * refactor: migrate react tests to typescript (#16318) * refactor: migrate custom 404 tests to typescript (#16350) * refactor: migrate vue tests to typescript (#16349) * refactor: migrate vue tests to typescript * fix import path * chore: trigger ci * fix(deps): update language tools (#16230) Co-authored-by: renovate[bot] <29139614+renovate[bot]@users.noreply.github.com> * chore: fix lock file (#16352) * refactor: migrate sitemap tests to typescript (#16353) * fix: stabilize client build output filenames across runs (#16348) Co-authored-by: Emanuele Stoppa <[email protected]> * changeset: add changeset for telemetry changes (#16257) * refactor: migrate alpinejs tests to typescript (#16354) * fix(core): fix append of assetQueryParams to inter-chunk JS *dynamic* imports (#16258) (#16282) Co-authored-by: Leif Marcus <[email protected]> * refactor: migrate markdoc tests to typescript (#16355) * refactor: migrate astro-rss tests to typescript (#16357) * fix(dev): Passing on allowedDomains configuration.
