三、plugins

一、安装依赖

cnpm i html-webpack-plugin -S
// 自动生成index.js文件
cnpm i clean-webpack-plugin -S
//清除dist目录下需要的文件

二、配置

const HtmlWebpackPlugin=require("html-webpack-plugin")
const config={
    .....
    plugins:[
        new HtmlWebpackPlugin({
            title:"kj"
        })
    ],
    mode:'development' // 模式
}
module.exports=config

三、清除

const CleanWebpackPlugin=require("clean-webpack-plugin")
new CleanWebpackPlugin()

const CleanWebpackPlugin=require("clean-webpack-plugin")
plugins:[
        new HtmlWebpackPlugin({
            title:"kj"
        }),
#       new CleanWebpackPlugin()
    ],
