- 新建文件夹后在
teaminal里安装
npm init -y
npm install -D webpack webpack-cli typescript ts-loader
npm install -D html-webpack-plugin
npm install -D webpack-dev-server // 热更新
npm install -D clean-webpack-plugin // 清除dist文件
npm install -D @babel/core @babel/preset-env babel-loader core-js // 兼容性处理
- 新建
webpack.config.js进行配置

const { CleanWebpackPlugin } = require('clean-webpack-plugin');
// webpack 所有配置信息
module.exports = {

// 告诉webpack不用箭头函数 兼容ie第一步
environment:{
arrowFunction : false
}
},
// webpack打包时使用的模块
module: {
// 指定加载的规则

{
// test 指定规则生效的文件
