Description

Applied changes from #24 and #27 to the main branch after the environment API PR is merged.
Also fixed errors on Windows and cleaned up some unneeded changes.

#24 implemented build-time dep optimization partially, but I didn't include that change in this PR.

e2e test status

missing feature list that was supported by esbuild / rollup

• watch mode ([Feature Request]: watch mode rolldown#2028)
  • options.watch
  • watcher.on('event', listener)
  • related hooks: shouldTransformCachedModule, watchChange, closeWatcher
  • this.addWatchFile
• meta on module info: this can be workarounded as it's not part of the public API
• system format
• generating multiple formats in one build: output is currently an object instead of an array
• options.attributes for resolveId hook
• resolveImportMeta hook: can use transform hook for Vite's usecase
• options.preserveEntrySignatures: not necessary but nice for smaller bundles
• cancelling the running build / scan (esbuild docs): since rolldown is fast, it's not important to have this feature, but would be nice to reduce energy consumption
• options around the optimizer: 9d7d4f0

oxc missing feature list that was supported by esbuild

• experimental decorators support ([Bug]: passes TypeScript experimental decorators as-is rolldown#2296)
• useDefineForClassFields (transformer: typescript --useDefineForClassFields oxc-project/oxc#6735)

native plugin incompatibilities

• alias: does not support customResolver option
• import-glob
  • does not support alias
  • does not support subpath imports: https://github.com/rolldown/rolldown/blob/4caa0a93f9ed42bcf9e152c6a4949bacd879b932/crates/rolldown_plugin_import_glob/src/lib.rs#L457
• manifest: cannot use data on Vite side (e.g. css/assets) and needs to be environment-specific
  • I cannot make a simple reproduction for this one. If you only enable the native manifest plugin and run build in playground/backend-integration, you can see the manifest not containing css and assets field in index.html.
  • needs to use different options for each environment

intended behavior differences

• transformer: define does not share reference for objects oxc-project/oxc#7641
• require is never transformed into import, users needs to inject a polyfill on their own, see f4c3629

TODO list for me

• think about what to do with commonjsOptions
• vitepress assigns to bundle: https://github.com/vuejs/vitepress/blob/68150a6f3349c1741ed5683e3010d9ecea02f3a8/src/node/plugin.ts#L353-L362
• organize what is left to make it possible to release rolldown-vite / rolldown-vite (with native plugins)
  • rolldown-vite
    • first make a resolver plugin using oxc-resolver and add an option to use that in non-rolldown vite?
  • rolldown-vite (with native plugins)
    • how to make native plugins work in dev? (e.g. use non-native for dev)
• convert esbuild.tsconfigRaw/esbuild.tsconfig to oxc
• parseAst
