Edit on StackBlitz ⚡️

File system based api exports convention, like nextjs. files under src/exports will setup main/module/typings/exports/typesVersions in package.json

install

pnpm i rollup-plugin-condition-exports

usage

import commonjs from '@rollup/plugin-commonjs'
import typescript from 'rollup-plugin-typescript2'
+import ce from 'rollup-plugin-condition-exports'
import { defineConfig } from 'rollup'

export default defineConfig([
  {
    plugins: [
      typescript(), // so Rollup can convert TypeScript to JavaScript
      commonjs(),
+     ce(),
    ],
    output: [
      { dir: 'cjs', format: 'cjs' },
      { dir: 'es', entryFileNames: '[name].mjs', format: 'es' },
    ],
  },
])
