关于react.js:react项目利用reactapprewired实现按需打包

cnpm i react-app-rewired customize-cra babel-plugin-import -D

根目录新建config-overrides.js

const {override,fixBabelImports} = require('customize-cra')

// override返回一个函数   该函数返回对象作为webpack的配置对象

module.exports = override(

 fixBabelImports("import",{

 libraryName:'antd',  //库名

 libraryDirectory:'es', //文件夹名

 style:'css'  //一个叫css.js的文件

 })

)

package.json

script改成

"scripts": {

 "start": "react-app-rewired start",

 "build": "react-app-rewired build",

 "test": "react-app-rewired test",

 "eject": "react-app-rewired eject"

 },

应用

import React, { Component } from 'react'

import {Button} from 'antd'

export default class Text extends Component {

 render() {

 return (

 <div>

 <Button type="primary">BUtton</Button>

 </div>

 )

 }

}
