feat: rolldown vite full bundle mode #107

underfin · 2025-04-09T09:52:20Z

Current status

Rolldown vite already integrated rolldown at dev build, could using npx vite --fullBundleMode to preview it. It only used at client build, the ssr is not supported at now.

integrated HMR features

propagate to root
self accept
accept deps
import.hot.invalidate
(wip) import.hot.acceptExports
(pending) CSS hmr
(new) support load module exports by import.meta.hot.getExports(), react plugin ref

Plugins

(wip) react plugin

Test status

define
hmr-root
(wip) hmr

Break changes

The xxx.html could be seen at original vite dev, but not added it to build.rollupOptions.input. In full bundle mode, you need to add the build.rollupOptions.input to make sure the HTML could be seen.rolldown vite test ref
The xxx.js could be seen at original vite dev, but it can't at full bundle mode.react plugin test ref
The html transformIndexHtml default order is post, it will inject some code to HTML, if it need to import module, it can't work at full bundle mode. The injected code need to bundled, you need to set the order to pre. react plugin ref

Break changes but could be improved

The implicit feature with soft invalidate, it make sure the transform hook is called once at original vite. In full bundle mode, it should be once, but not implement at now, we could improve it at future. rolldown vite test ref
The html transformIndexHtml is running at build, the config.server is invalid. react plugin ref

-        '\t...typeof m === "object" && !Array.isArray(m) || typeof m === "function" ? m : {},\n' +
-        '\tdefault: m\n' +
-        '})(__vite__cjsImport0_react)',
+        'const react = ((m) => m?.__esModule ? m : { ...typeof m === "object" && !Array.isArray(m) || typeof m === "function" ? m : {}, default: m })(__vite__cjsImport0_react)',


It is wired for it coudle be success at rolldown-vite branch.

It's probably caused by the "vitest>vite" overrides. Vitest uses Vite to process the files and that changes the Function::toString result.

+    function importModuleWithFullBundleMode() {
+      const importPromise = import(base + url)
+      return importPromise.then(() =>
+        // @ts-expect-error globalThis.__rolldown_runtime__


In the future, I think it's good to have the types exposed from rolldown so that we can use it like:

declare var __rolldown_runtime__: RolldownHmrRuntime

We should probably support middleware mode (it does not have server.httpServer) in the future.

-                  isBuild: config.command === 'build',
+                  isBuild,


Shouldn't this be instead? Does it actually need to set isBuild: false? If so, why?

isBuild: config.command === 'build', optimizeDeps: false,

The full bundle mode also is build, here only add a condition with config.command === 'build' || experimental.fullBundleMode. The production mode maybe could be removed.
Here need to ensure consistency with build.

+    treeshake: experimental.fullBundleMode
+      ? false
+      : options.rollupOptions.treeshake,


Why does this have to be false?

The treeshake will remove unused code, but the unused code maybe using at hmr.
