Details

astro

[WIP]

• ❌ uses missing features
  • uses meta.chunks in renderChunk hook, also does delete chunk.modules[id]
    • https://github.com/withastro/astro/blob/46ec06ed82887eaf1fe3a73158407b496669c5f0/packages/astro/src/core/build/plugins/plugin-css.ts#L172-L175
• ❌ many tests failing
  • TODO: need to investigate further

marko

• ⚠️ Errors because it tries to update input option in buildStart
  • Added a patch to update input option in options hook
• ✅ passed by converting esbuild plugins to rollup plugins

nuxt

• ⚠️ uses function type outputOptions.assetFileNames in generateBundle hook
  • it can be workaround by using this.environment.config.build.rollupOptions.output.assetFileNames (applied this workaround)
  • rolldown/rolldown#3445

qwik

• ⚠️ uses missing features
  • manualChunks
    • wants to group chunks by entry (code, introduced in QwikDev/qwik#6670, related issue rollup/rollup#5574)
  • preserveSignature option in this.emitFile({ type: 'chunk' })
    • rolldown/rolldown#3500
• ✅ pnpm tsx --require ./scripts/runBefore.ts starters/dev-server.ts 3301 hanged
  • added a fix, probably because there was a dead-lock

sveltekit

better to run with CI=1 as some tests are flaky and setting that will retry them

• ⚠️ uses manualChunks but can be replaced with advancedChunks
  • Note that the test expects a single chunk to be output, but rolldown outputs 5 chunks (probably because it'll break the execution order), I guess this is fine maybe not (sveltejs/kit#3882), it seems they want to make sure there's a single chunk
  • Also found some issue with experimental.strictExecutionOrder: rolldown/rolldown#3410
• ✅ tests in apps/dev-only
  • passed by converting esbuild plugins to rollup plugins

unocss

• ❌ test/fixtures.test.ts > fixtures > vite client/test/fixtures.test.ts > fixtures > vite lib/test/fixtures.test.ts > fixtures > vite lib rollupOptions fails
  • UnoCSS modifies chunk.modules to fool the css plugin to generate the css in corresponding chunk (unocss/unocss#4403)

vike

• uses missing features
  • ❌ uses manualChunks that requires callbacks
    • https://github.com/vikejs/vike/blob/ea3a84264222768b9869e5f87ce4429e0685f3ae/vike/node/plugin/plugins/distFileNames.ts#L45-L101
    • introduced to workaround vikejs/vike#1815
    • maybe this can be workaround by adding ?url to all CSS imports
• ❌ |e2e| test/preload/prod.spec.ts fails
  • because manualChunks is not supported

vite-plugin-svelte

• ⚠️ pnpm test:build
  • packages/e2e-tests/kit-node/__tests__/kit.spec.ts > kit-node > index route > should not include dynamic import from onmount in ssr output
    • caused by rolldown/rolldown#3403
• ✅ pnpm test:serve
  • passed by converting esbuild plugins to rollup plugins

vite-plugin-vue

The failing tests are

• ⚠️ playground/vue-lib/__tests__/vue-lib.spec.ts > vue component library > should output tree shakeable css module code
  • This is happening because OXC minifier does not drop non-used variables
• ✅ playground/vue-legacy/__tests__/vue-legacy.spec.ts
  • This is expected as rolldown-vite currently does not support the legacy plugin

waku

needs VITE_USE_LEGACY_PARSE_AST=1 (waiting for oxc-project/oxc#8983, released in OXC 0.50.0)

make sure to run with BROWSER=chromium if you have a different value set to BROWSER

• ⚠️ uses preserveEntrySignatures: 'exports-only'
  • rolldown/rolldown#3500
