详解使用WebPack搭建React开发环境

第一步、基础环境

初始化

项目初始化

npm init -y

安装webpack

npm i webpack

安装react

npm i react react-dom -s

项目基础框架

入口文件(src/index.js)

import React from \'react\'
import {render} from \'react-dom\'
import App from \'./App\'
render(<App/>,document.getElementById(\'root\'))

主组件(src/App.js)

import React,{Component} from \'react\'
class App extends Component{
  constructor(){
    super()
  }
  redner(){
    return(
      <div>
        App Module
      </div>
    )
  }
}  

webpack.config.js

const path = require(\'path\')
const StyleLintPlugin = require(\'stylelint-webpack-plugin\')
const STYLELINTENABLE = true
module.exports = {
  mode:\'development\',
  entry:\'./src/index.js\',
  output:{
    path:path.resolve(__dirname,\'build\'),
    filename:\'bundle.js\'
  },
  module:{
    rules:[
      //处理js/jsx
      {
        test:/\\.jsx?/i,
        use:{
          loader:\'bebel-loader\',
          options:{
            presets:[\'@babel/preset-react\']
          }
        }
      },
      //处理css
      {
        test:/\\.css$/i,
        use:[\'style-loader\',\'css-loader\',{
          loader:\'postcss-loader\',
          options:{
            plugins:require(\'autoprefixer\')
          }
        }]
      },
      //处理图片资源
      {
        test:/\\.(png|jpg|gif)$/i,
        use:{
          loader:\'url-loader\',
          options:{
            outputPath:\'imgs/\',
            limit:10*1024
          }
        }
      },
      //处理字体文件
      {
        test:/\\.(eot|svg|ttf|woof|woof2)$/i,
        use:{
          loader:\'url-loader\',
          options:{
            outputPath:\'fonts/\',
            limit:10*1024
          }
        }
      },
      //less
      {
        test:/\\.less$/i,
        use:[\'style-loader\',\'css-loader\',\'less-loader\']
      },

    ]
  },
  devtool:\'source-map\',
  plugins:[
    ...STYLELINTENABLE ?[
      new StyleLintPlugin({
        files:[\'**/*.css\',\'**/*.less\',\'**/*.js\',\'**/*.html\',\'**/*.vue\',\'**/*.scss\']
      })
    ]:[]
  ]
}

webpack.config.js

 \"stylelint\": {
  \"extends\": \"stylelint-config-standard\"
 },
 \"browserslist\":[
  \"> 0.5%\",//市场占有率大于百分之零点5
  \"last 2 version\",//最后两个版本
  \"not dead\"//还没有die
 ]
