reactjs - 如何使用webpack使图书馆真正可摇树？

我有一个包含多个react组件的库，并且我想使该库可树状摇动，以便在导入类似

import { Checkbox } from 'my-react-components'

我不导入整个捆绑包。

我的index.js看起来像这样

export { default as Button } from './components/Button'
export { default as Checkbox } from './components/Checkbox'
export { default as FlexView } from './components/FlexView'
export { default as Radio } from './components/Radio'
export { default as Select } from './components/Select'
export { default as TextInput } from './components/TextInput'
export { default as Toggle } from './components/Toggle'

我捆绑使用webpack

module.exports = {
  mode: 'production',
  entry: './src/index.ts',
  output: {
    path: path.resolve('./lib'),
    filename: 'react-components.js',
    libraryTarget: 'commonjs2',
  },

  // loaders and stuff...
  // terser-webpack-plugin...

  externals: {
    // don't include react in the bundle
    react: {
      root: 'React',
      commonjs2: 'react',
      commonjs: 'react',
      amd: 'react',
    },
  },
  optimization: {
    splitChunks: false,
    sideEffects: false,
  },
}

在我的babel配置中，我当然有

['@babel/preset-env', {
  modules: false,
}]

通过这种设置，当我仅导入一个组件时，整个捆绑包就包括在内（导入时我也在使用webpack）。我该如何预防？

最佳答案

我相信您还需要module上的package.json属性

{
   ...
   "main": "lib/index.js",
   "module": "lib/index.esm.js",
   ...
}
