how to integrate with oxc-transform-react?

[ianzone]

for react compiler

[Kxrma47]

The supported native integration is through @vitejs/plugin-react, which loads oxc-transform-react when compiler: true is set:

import react from '@vitejs/plugin-react'
import { defineConfig } from 'tsdown'

export default defineConfig({
  plugins: [react({ compiler: true })],
})

Install both with pnpm add -D @vitejs/plugin-react oxc-transform-react. If you also emit declarations, use exclude: [/node_modules/, /\.d\.ts$/] so the plugin does not transform generated .d.ts files. This is now documented in tsdown's React support recipe.
