fix: stream Fragment sync siblings before async children resolve by dataCenter430 · Pull Request #16239 · withastro/astro

dataCenter430 · 2026-04-07T01:34:02Z

Changes

renderFragmentComponent was calling renderSlotToString, which eagerly awaited the entire slot content into a string before returning a RenderInstance. This caused sync siblings inside a <Fragment> to block until all async children resolved, unlike <div> and bare template expressions which streamed immediately.
Fix: replace renderSlotToString with renderSlot, so Fragment children go through the same renderChild -> buffered async pipeline every other element uses.
Fixes Async Children of Fragments block earlier sibling elements from being streamed #13283

Testing

Added unit test in test/units/render/html-primitives.test.js verifying sync content flushes to the destination before a deferred Promise resolves.
Added integration tests in test/streaming.test.js using a fixture page that mirrors the issue's exact reproduction — asserts sync content arrives in an earlier stream chunk than the async child.
All 99 existing + new tests pass.

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).
