// webpack中如何使用 vue:
// 1. 安装vue 的包: cnpm i vue -S
// 2. 由于在 webpack 中,推荐使用 . vue 这个组件模板文件定义组件, 所以需要安装能解析这种文件的loader cnpm i vue-loader vue-template-compiler -D
// 3. 在main.js 中导入 vue的包, import Vue from 'vue'
// 4. 定义一个处理.vue 结尾的规则 { test: /\.vue$/, use: 'vue-loader' }
// 5. 导入需要的组件. import login from './login.vue'
// 6. 使用 render 渲染login. render: c => c(login)
// webpack.config.js
// webpack 是基于node构建的,webpack的配置文件中,任何合法的Node代码都是支持的
var path = require('path')// 在内存中生成src下的index.html,同时自动将打包好的bundle.js 导入到页面中
var htmlWebpackPlugin = require('html-webpack-plugin')// 当以命令行形式运行webpack 或 webpack-dev-server 的时候,工具会发现,我们并没有提供 要打包的文件的入口和出口文件,此时,他会在webapck.config.js 中寻找 入口和出口文件
module.exports = {entry: path.join(__dirname, './src/main.js'), // 入口文件output: {path: path.join(__dirname, './dist'), // 指定输出文件的名称filename: 'bundle.js' // 指定输出文件的名称},module: {rules: [{ test: /\.css$/, use: ['style-loader', 'css-loader'] },{ test: /\.less$/, use: ['style-loader', 'css-loader', 'less-loader'] },{ test: /\.scss$/, use: ['style-loader', 'css-loader', 'sass-loader'] },{test: /\.(jpg|png|gif|bmp|jpeg)$/,use: 'url-loader?limit=5000&name=[hash:8]-[name].[ext]'}, // 处理图片路径的url// 图片的大小 >= limit 不会被转为base64 , 否则 转为base64格式{// 处理字体文件的配置test: /\.(ttf|eot|svg|woff|woff2)$/,use: 'url-loader?limit=5000&name=[hash:8]-[name].[ext]'},{// 配置 babel 来转换 es语法test: /\.js$/,use: 'babel-loader',exclude: /node_modules/},{test: /\.vue$/,use: 'vue-loader'}]},plugins: [// 所有webpack 插件的配置new htmlWebpackPlugin({template: path.join(__dirname, './src/index.html'),filename: 'index.html'})],resolve: {alias: {// "vue$":'vue/dist/vue.js'}}
