前端工程化（二）---webpack配置
导航
继续上一遍的配置，本节主要记录webpack的配置过程
webpack的基础知识可以参照官方文档：webpack中文官网
一些知识点
目前在我的项目中起到的作用：
1、webpack在前端工程打包过程中起到了什么作用
声明入口（entry）：通俗来讲，就是项目的构建过程是从哪开始，指定的是一个或多个js文件。前端开发，都是基于es6的模块化概念的，每一个文件都可以认为是一个模块，模块之间使用import语句相互引用，相互协作。这种依赖最终会形成一颗依赖树，而入口文件就是树的根。webpack 会找出有哪些模块和库是入口起点（直接和间接）依赖的。每个依赖项随即被处理，最终输出到**.bundles文件中
声明出口（output）：其实就是构建输出目录，也就是前端工程化（一）---工程基础目录搭建中创建的dist目录
对于非JavaScript文件的处理（loader）：webpack自身只能理解JavaScript，在模块依赖过程中，除了.js文件外，对于vue、css等模块的import是无法理解的。loader将vue、css、图片等信息转化为webpack能理解的方式，从而完成模块之间的依赖
插件的应用（plugin）：比如常用的HtmlWebpackPlugin插件、ProvidePlugin等，辅助项目的构建
2、webpack-dev-server
类似于tomcat、是前端的web容器。前端工程打包后，就通过它访问
3、webpack-merge模块的使用
可以使webpack的配置文件拥有类似于继承的关系。而前端项目的构建是要分环境的，比如开发环境、正式环境。我们可以将通用的配置抽取为common配置，然后让开发环境与正式环境的配置分别继承自common，这样好维护
4、webpack的路径
在配置entry等需要制定文件位置的元素的时候，需要指定文件所在的路径。
刚刚接触webpack的时候，总是被路径搞糊涂，总是提示找不到文件。
记住一点，一定要利用"__dirname"来配置文件的路径(注意，是两个下划线)。
“__dirname”是node.js中的一个全局变量，它指向当前执行脚本所在的目录。在webpack的配置文件中使用__dirname，那就代表当前的配置文件所在的路径
文件路径=__dirname+相对路径
具体配置过程
注意：一定要搞清楚自己安装的webpack版本，不同的版本配置是有所不同的。比如从webpack2->webpack4这种大版本跳跃，对于loader的配置是有很大的区别的。我当前的webpack版本是4.5.0
前端工程化（一）---工程基础目录搭建 中已经介绍了如何安装webpack，下面直接介绍配置的过程
1、新建webpack配置文件
在工程的根目录下，新建如下文件
webpack.common.js：通用配置。主要是entry、output、loader、插件的配置
webpack.dev.js：开发环境的配置。主要配置devtool、代理等信息
webpack.prod.js：生产环境的配置。
2、安装项目依赖的模块
使用cnpm i 模块名 --save-dev 命令安装项目的依赖
以下是安装过程，有几点需要注意
第40行，提示模块需要webpack3.1.0的依赖，但是安装的却是4.2.0。这说明正式版本的extract-text-webpack-plugin还没有与webpack最新版本同步。这时需要在模块后面加上版本信息“@next”
第46行，提示没有找到iview需要依赖的vue模块。安装上vue就可以了
安装过程要注意警告信息，否则安装的模块可能会不生效

安装的内容主要包括：各种loader、插件。由于项目是基于vue、iView开发的，因此也添加了这两部分的依赖。最后的package.json结果：

3、配置webpack
webpack.common.js的配置
值得注意的是
第96行的jquery引入方式，Vue虽然不建议类似于Jquery这样的类库去直接操作DOM，但是某些场景下，使用JQuery还是很方便的，比如使用$.extend来扩展对象，一般都是在编写组件的时候用到
第4~7行是node引入模块的方式。这种方式能够成功的引入模块，是依赖于本地的模块库，也就是项目根目录下的node_modules文件夹
1 /* 2 通用配置 3 */ 4 const path = require('path') 5 const HtmlWebpackPlugin = require('html-webpack-plugin') 6 const webpack = require('webpack') 7 const ExtractTextPlugin = require("extract-text-webpack-plugin") 8 module.exports = { 9 entry:{ 10 index:path.join(__dirname,'src/index.js'), 11 login:path.join(__dirname,'src/login.js') 12 }, 13 output: { 14 filename: 'js/[name].bundle.js', 15 path: path.resolve(__dirname, 'dist') 16 }, 17 module:{ 18 rules: [ 19 // 解析vue文件 20 { 21 test:/\.vue$/, 22 use:[ 23 'vue-loader', 24 { 25 loader:'iview-loader', 26 options:{ 27 prefix:false 28 } 29 } 30 ] 31 }, 32 // 使用babel解析js文件，当js文件中包含es6的时候，需要它 33 { 34 test: /\.js$/, 35 exclude: /(node_modules|bower_components)/, 36 use: { 37 loader: 'babel-loader', 38 options: { 39 presets: ['env'] 40 } 41 } 42 }, 43 // 管理样式资源，使js文件能够引入css模块 44 // 抽取样式文件为单独的css文件 45 { 46 test:/\.css$/, 47 // use:[ 48 // 'style-loader', 49 // 'css-loader' 50 // ] 51 use: ExtractTextPlugin.extract({ 52 fallback: "style-loader", 53 use: "css-loader" 54 }) 55 }, 56 { 57 test:/\.less$/, 58 use:[ 59 'style-loader', 60 'css-loader', 61 'less-loader' 62 ] 63 }, 64 // 管理图片文件，使css文件能够对图片引用 65 { 66 test:/\.(png|svg|jpg|gif)$/, 67 use:[ 68 { 69 loader:'file-loader', 70 options:{ 71 name:'img/[name].[hash:8].[ext]' 72 } 73 } 74 ] 75 }, 76 // 管理字体文件 77 { 78 test:/\.(woff|woff2|eot|ttf|otf)$/, 79 use:[ 80 { 81 loader:'file-loader', 82 options:{ 83 name:'img/[name].[hash:8].[ext]' 84 } 85 } 86 ] 87 } 88 ] 89 }, 90 91 plugins: [ 92 // new HtmlWebpackPlugin({ 93 // title: 'Production' 94 // }), 95 // shimming配置，使jquery能够在所有模块中使用 96 new webpack.ProvidePlugin({ 97 $:'jquery' 98 }), 99 // 将css样式文件从js 打包中抽取出来，形成名字叫styles.css的文件 100 new ExtractTextPlugin("[name].css"), 101 new HtmlWebpackPlugin({ 102 // 文件title，如果不使用模板，那么直接就会显示在生成的文件中 103 // 如果使用了模板，那么就要使用表达式<%=htmlWebpackPlugin.options.title%> 104 title:'后台主页', 105 //生成目标文件的名字 106 filename:'index.html', 107 //可以指定生成目录 108 // filename:'assets/index.html' 109 // 指定模板 110 template:'./src/assets/templates/index.html', 111 // 指定资源引入的script标签位置 112 inject:'header', 113 // 加入icon图标 114 favicon:'./src/assets/icons/logo.net.ico', 115 // 压缩代码 116 // 具体选项见https://github.com/kangax/html-minifier#options-quick-reference 117 minify:{ 118 // 去除注释 119 removeComments:false, 120 // 压缩HTML代码，变成一行 121 collapseWhitespace:false 122 }, 123 // 在html页面引入打包后的js和css资源的时候，加上hash码 124 // hash:true, 125 cache:true, 126 // 在生成html的过程中，如果出现错误，则显示在html页面上，默认为true 127 showErrors:true, 128 chunks:[ 129 'index' 130 ] 131 }), 132 new HtmlWebpackPlugin({ 133 filename:'login.html', 134 title:'欢迎您，请登录', 135 hash:false, 136 template:'./src/assets/templates/login.html', 137 showErrors:true, 138 chunks:[ 139 'login' 140 ], 141 // 指定资源引入的script标签位置 142 inject:'header', 143 // 加入icon图标 144 favicon:'./src/assets/icons/logo.net.ico', 145 // 压缩代码 146 // 具体选项见https://github.com/kangax/html-minifier#options-quick-reference 147 minify:{ 148 // 去除注释 149 removeComments:false, 150 // 压缩HTML代码，变成一行 151 collapseWhitespace:false 152 }, 153 }) 154 ], 155 }
webpack.dev.js的配置
值得注意的是
devServer的作用：它是webpack-dev-server的配置项，可以定义开启端口等web容器相关的信息。具体的配置信息参见官方文档
另外就是proxy的配置：它是用来解决跨域问题的。由于项目是前后端分离的，因此肯定会涉及到跨域，配置中的意思就是如果请求是以'/api'开头的，那么就要转发到'http://192.168.0.103:8081'这个地址上，而这个地址正是后端服务器监听的端口
1 /* 2 开发环境配置 3 */ 4 const merge = require('webpack-merge') 5 const common = require('./webpack.common.js') 6 const webpack = require('webpack') 7 8 9 // const express = require('express') 10 // const app = express() 11 // const appData = require('./src/assets/data/menuData.json') 12 // const userList = require('./src/assets/data/userList.json') 13 // var apiRoutes = express.Router() 14 // app.use('/data', apiRoutes) 15 16 module.exports = merge(common, { 17 // 有助于代码调试 18 // 开启后，控制台会显示错误所在的具体js文件 19 // 生产环境下不要使用 20 devtool: 'inline-source-map', 21 mode: 'development', 22 devServer: { 23 contentBase: './dist', 24 // before(app){ 25 // app.get('/data/menuData',(req,res)=>{ 26 // res.json({ 27 // errno:0, 28 // data:appData 29 // }) 30 // }), 31 // app.get('/data/userList',(req,res)=>{ 32 // res.json({ 33 // errono:0, 34 // data:userList 35 // }) 36 // }) 37 // }, 38 proxy: { 39 '/api': { 40 // target: 'http://192.168.0.111:8080',//设置你调用的接口域名和端口号 别忘了加http 41 // target:'http://192.168.0.101:8081',//集成环境 42 target: 'http://192.168.0.103:8081',//本地环境 43 changeOrigin: true, 44 pathRewrite: { 45 '^/api': ''//这里理解成用‘/api’代替target里面的地址，后面组件中我们掉接口时直接用api代替 比如我要调用'http://40.00.100.100:3002/user/add'，直接写‘/api/user/add’即可 46 } 47 } 48 }, 49 open: false 50 }, 51 // plugins: [ 52 // new webpack.DefinePlugin({ 53 // 'process.env.NODE_ENV': JSON.stringify('development') 54 // }) 55 // ] 56 });
webpack.prod.js的配置
1 /* 2 生产环境配置 3 */ 4 const merge = require('webpack-merge') 5 const UglifyJSPlugin = require('uglifyjs-webpack-plugin') 6 const common = require('./webpack.common.js') 7 const CleanWebpackPlugin = require('clean-webpack-plugin') 8 // const webpack = require('webpack') 9 module.exports = merge(common, { 10 //关于source-map，官网中的解释看不明白，以后再说 11 devtool: 'source-map', 12 mode: 'production', 13 plugins: [ 14 new CleanWebpackPlugin(['dist']), 15 new UglifyJSPlugin({ 16 sourceMap: true 17 }), 18 // new CleanWebpackPlugin(['dist']), 19 // new webpack.DefinePlugin({ 20 // 'process.env.NODE_ENV': JSON.stringify('production') 21 // }) 22 ] 23 })
4、项目启动脚本的配置
修改package.json文件，增加启动脚本，红色字体部分
1 { 2 "name": "syinfo", 3 "version": "1.0.0", 4 "description": "管理系统", 5 "main": "index.js", 6 "scripts": { 7 "test": "echo \"Error: no test specified\" && exit 1", 8 "start": "webpack-dev-server --config webpack.dev.js", 9 "build": "webpack --config webpack.prod.js" 10 }, 11 "author": "lichking2017", 12 "license": "ISC", 13 "devDependencies": { 14 "axios": "^0.18.0", 15 "babel-core": "^6.26.0", 16 "babel-loader": "^7.1.4", 17 "babel-preset-env": "^1.6.1", 18 "clean-webpack-plugin": "^0.1.19", 19 "css-loader": "^0.28.11", 20 "express": "^4.16.3", 21 "extract-text-webpack-plugin": "^4.0.0-beta.0", 22 "file-loader": "^1.1.11", 23 "html-loader": "^0.5.5", 24 "html-webpack-plugin": "^3.2.0", 25 "iview": "^2.12.0", 26 "iview-loader": "^1.0.0", 27 "jquery": "^3.3.1", 28 "less": "^3.0.1", 29 "less-loader": "^4.1.0", 30 "style-loader": "^0.20.3", 31 "uglifyjs-webpack-plugin": "^1.2.4", 32 "vue": "^2.5.16", 33 "vue-loader": "^14.2.2", 34 "vue-router": "^3.0.1", 35 "vue-template-compiler": "^2.5.16", 36 "webpack": "^4.5.0", 37 "webpack-dev-server": "^3.1.1", 38 "webpack-merge": "^4.1.2" 39 } 40 }
5、启动
执行如下命令启动
cnpm run start
以下是我自己的项目的启动信息：
