我是靠谱客的博主雪白鲜花，这篇文章主要介绍Vue中的webpack打包（重点：webpack.config.js与package.json），现在分享给大家，希望可以做个参考。

node 环境
npm init -y 初始化项目
生成了pageage.json文件夹
在项目文件夹里建 src文件添加入口文件 index.js

webpack核心模块

entry：入口
output：出口输出
module：配置loader loader处理非js的文件打包
plugins：插件
mode：模式 development 开发模式 production 生产模式

webpack 安装

全局安装
cnpm i -g webpack webpack-cli
局部暗转
cnpm install --save-dev webpack webpack-cli
cnpm i -D webpack webpack-cli

webpack ./src/index.js -o ./dist/main.js --mode=development
未设置webpack.config.js文件中入口和出口时，在命令行可以执行用来打包

loader安装
安装 css-loader
cnpm i -D css-loader style-loader
安装 less-loader
cnpm i -D less-loader less
安装 babel-loader
cnpm install babel-loader @babel/core @babel/preset-env -D

webpack-dev-server 开发服务器

安装 cnpm i -D webpack-dev-server

插件 html-webpack-plugin
安装 cnpm i -D html-webpack-plugin

webpack.config.js
复制代码const path = require('path') const HtmlWebpackPlugin = require('html-webpack-plugin') module.exports = { entry: './src/index.js', //配置入口文件 output: { //打包后的文件名 filename: 'main.js', // 打包后的路径，必须是绝对路径，不设置时默认是 dist/main.js path: path.resolve(__dirname, './dist') }, // 模式开发模式生产模式 mode: 'development', // mode: 'production', module: { rules: [{ test: /.css$/, // use 里面有顺序，从后往前执行，先模块化再引入 use: ['style-loader', { loader: 'css-loader', options: { esModule: false, url: true } }] }, { test: /.less$/, // use 里面有顺序，从后往前执行，先模块化再引入 use: ['style-loader', 'css-loader', 'less-loader'] }, { test: /.js$/, exclude: /node_modules/, use: { loader: 'babel-loader', options: { presets: ['@babel/preset-env'] } } }, { test: /.png|.jpeg$/i, // use 里面有顺序，从后往前执行，先模块化再引入 use: { loader:'url-loader', options:{ esModule:false, } } } ] }, devServer: { open: true, //自动打开浏览器 port: 3000, //端口的配置 hot: true, //热加载 compress: true, // static:'./src' }, plugins: [ new HtmlWebpackPlugin({ filename: 'index.html', template: './public/index.html' }) ] }
