build文件夹新建webpack.base.conf.js,webpack.dev.conf.js,webpack.prod.conf.js
- webpack.base.conf.js 存放公共配置
- webpack.prod.conf.js 存放生产环境配置
- webpack.dev.conf.js 存放开发环境配置
创建src文件夹并创建main.js
创建index.html
<pre class="prettyprint prettyprinted" style="box-sizing: border-box; outline-style: none; font-family: Menlo, Monaco, Consolas, "Courier New", monospace; font-size: 12px; margin: 0px -15px 15px; overflow: auto; display: block; color: rgb(68, 68, 68); background-color: rgb(249, 249, 249); border: none; padding: 15px; border-radius: 0px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: 0.45px; orphans: 2; text-align: left; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;"><!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <meta http-equiv="X-UA-Compatible" content="ie=edge"> <title>webpack搭建vue项目</title> </head> <body> <div id="app"></div> </body> </html>复制代码</pre>
下载webpack webpack-dev-server webpack-cli
<pre style="box-sizing: border-box; outline-style: none; font-family: Menlo, Monaco, Consolas, "Courier New", monospace; font-size: 12px; margin: 0px -15px 15px; overflow: auto; display: block; color: rgb(68, 68, 68); background-color: rgb(249, 249, 249); border-width: 1px 0px; border-right-style: initial; border-left-style: initial; border-right-color: initial; border-left-color: initial; border-image: initial; border-top-style: solid; border-top-color: rgb(240, 240, 240); border-bottom-style: solid; border-bottom-color: rgb(240, 240, 240); padding: 10px 15px; border-radius: 0px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: 0.45px; orphans: 2; text-align: left; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">npm i webpack webpack-dev-server webpack-cli -D复制代码</pre>
打开webpack.base.config.js,并配置webpack整体属性

4.配置loader
- 下载babel-loader,babel-core,babel-preset-dev,rules并配置js
babel-preset-env 帮助我们配置 babel。我们只需要告诉它我们要兼容的情况(目标运行环境),它就会自动把代码转换为兼容对应环境的代码。
babel-core是作为babel的核心存在,babel的核心api都在这个模块里面
tips: babel是7.X的话babel-core必须是6.X,否则不兼容
<pre class="prettyprint prettyprinted" style="box-sizing: border-box; outline-style: none; font-family: Menlo, Monaco, Consolas, "Courier New", monospace; font-size: 12px; margin: 0px -15px 15px; overflow: auto; display: block; color: rgb(68, 68, 68); background-color: rgb(249, 249, 249); border: none; padding: 15px; border-radius: 0px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: 0.45px; orphans: 2; text-align: left; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">npm i babel-loader babel-core babel-preset-env@7 -D复制代码</pre>

可以看到项目已经跑起来了
11. 区分环境引入不同地址
- 新建config文件夹并新建dev.ev.js和prod.env.js
dev.env.js 开发环境配置
<pre class="prettyprint prettyprinted" style="box-sizing: border-box; outline-style: none; font-family: Menlo, Monaco, Consolas, "Courier New", monospace; font-size: 12px; margin: 0px -15px 15px; overflow: auto; display: block; color: rgb(68, 68, 68); background-color: rgb(249, 249, 249); border: none; padding: 15px; border-radius: 0px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: 0.45px; orphans: 2; text-align: left; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">'use strict' module.exports = { NODE_ENV: '"development"', BASE_API: '"http://1456"', }复制代码</pre>
prod.env.js 生产环境配置
<pre class="prettyprint prettyprinted" style="box-sizing: border-box; outline-style: none; font-family: Menlo, Monaco, Consolas, "Courier New", monospace; font-size: 12px; margin: 0px -15px 15px; overflow: auto; display: block; color: rgb(68, 68, 68); background-color: rgb(249, 249, 249); border: none; padding: 15px; border-radius: 0px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: 0.45px; orphans: 2; text-align: left; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">'use strict' module.exports = { NODE_ENV: '"production"', BASE_API: '"http://123.com"', }复制代码</pre>
12.优化webpack配置
- 解决更改文件打包时dist文件没有清除,再次打包。
下载clean-webpack-plugin,并配置webpack.prod.conf.js文件
<pre style="box-sizing: border-box; outline-style: none; font-family: Menlo, Monaco, Consolas, "Courier New", monospace; font-size: 12px; margin: 0px -15px 15px; overflow: auto; display: block; color: rgb(68, 68, 68); background-color: rgb(249, 249, 249); border-width: 1px 0px; border-right-style: initial; border-left-style: initial; border-right-color: initial; border-left-color: initial; border-image: initial; border-top-style: solid; border-top-color: rgb(240, 240, 240); border-bottom-style: solid; border-bottom-color: rgb(240, 240, 240); padding: 10px 15px; border-radius: 0px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: 0.45px; orphans: 2; text-align: left; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">npm i clean-webpack-plugin -D复制代码</pre>
<pre class="prettyprint prettyprinted" style="box-sizing: border-box; outline-style: none; font-family: Menlo, Monaco, Consolas, "Courier New", monospace; font-size: 12px; margin: 0px -15px 15px; overflow: auto; display: block; color: rgb(68, 68, 68); background-color: rgb(249, 249, 249); border: none; padding: 15px; border-radius: 0px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: 0.45px; orphans: 2; text-align: left; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">// 引入clean-webpack-plugin var CleanWebpackPlugin = require('clean-webpack-plugin'); // 省略代码。。。。 plugins: [ new CleanWebPackPlugin(); ]复制代码</pre>
- 根据不同环境提取css
下载mini-css-extract-plugin,并配置webpack.prod.conf.js文件
<pre style="box-sizing: border-box; outline-style: none; font-family: Menlo, Monaco, Consolas, "Courier New", monospace; font-size: 12px; margin: 0px -15px 15px; overflow: auto; display: block; color: rgb(68, 68, 68); background-color: rgb(249, 249, 249); border-width: 1px 0px; border-right-style: initial; border-left-style: initial; border-right-color: initial; border-left-color: initial; border-image: initial; border-top-style: solid; border-top-color: rgb(240, 240, 240); border-bottom-style: solid; border-bottom-color: rgb(240, 240, 240); padding: 10px 15px; border-radius: 0px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: 0.45px; orphans: 2; text-align: left; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">npm i mini-css-extract-plugin -D复制代码</pre>
更改webpack.prod.conf.js中使用vue-style-loader的代码,更改为
<pre class="prettyprint prettyprinted" style="box-sizing: border-box; outline-style: none; font-family: Menlo, Monaco, Consolas, "Courier New", monospace; font-size: 12px; margin: 0px -15px 15px; overflow: auto; display: block; color: rgb(68, 68, 68); background-color: rgb(249, 249, 249); border: none; padding: 15px; border-radius: 0px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: 0.45px; orphans: 2; text-align: left; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">module: { rules: [ { test: /.(c|sc|sa)ss/, use: [ { loader: MiniCssExtractPlugin.loader, }, 'css-loader', 'less-loader' ] } ] }, 复制代码</pre>
在webpack.prod.conf.js的plugin中配置
<pre class="prettyprint prettyprinted" style="box-sizing: border-box; outline-style: none; font-family: Menlo, Monaco, Consolas, "Courier New", monospace; font-size: 12px; margin: 0px -15px 15px; overflow: auto; display: block; color: rgb(68, 68, 68); background-color: rgb(249, 249, 249); border: none; padding: 15px; border-radius: 0px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: 0.45px; orphans: 2; text-align: left; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">new MiniCssExtractPlugin({ filename: '[name].[hash].js' })复制代码</pre>
webpack.base.conf.js中删除使用vue-style-loader的代码,并在webpack.dev.conf.js中定义
<pre class="prettyprint prettyprinted" style="box-sizing: border-box; outline-style: none; font-family: Menlo, Monaco, Consolas, "Courier New", monospace; font-size: 12px; margin: 0px -15px 15px; overflow: auto; display: block; color: rgb(68, 68, 68); background-color: rgb(249, 249, 249); border: none; padding: 15px; border-radius: 0px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: 0.45px; orphans: 2; text-align: left; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">module: { rules: [ { test: /.(c|sc|sa)ss/, use: [ { loader: 'vue-style-loader', }, 'css-loader', 'less-loader' ] } ] },复制代码</pre>
这个配置vue-loader中有提到 vue-loader.vuejs.org/zh/guide/ex…
- 第三方库单独打包
把依赖的第三方库抽取出来单独打包,加快打包进度
下载autodll-webpack-plugin
<pre style="box-sizing: border-box; outline-style: none; font-family: Menlo, Monaco, Consolas, "Courier New", monospace; font-size: 12px; margin: 0px -15px 15px; overflow: auto; display: block; color: rgb(68, 68, 68); background-color: rgb(249, 249, 249); border-width: 1px 0px; border-right-style: initial; border-left-style: initial; border-right-color: initial; border-left-color: initial; border-image: initial; border-top-style: solid; border-top-color: rgb(240, 240, 240); border-bottom-style: solid; border-bottom-color: rgb(240, 240, 240); padding: 10px 15px; border-radius: 0px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: 0.45px; orphans: 2; text-align: left; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">npm i autodll-webpack-plugin -D复制代码</pre>
在webpack.base.conf.js中配置
<pre class="prettyprint prettyprinted" style="box-sizing: border-box; outline-style: none; font-family: Menlo, Monaco, Consolas, "Courier New", monospace; font-size: 12px; margin: 0px -15px 15px; overflow: auto; display: block; color: rgb(68, 68, 68); background-color: rgb(249, 249, 249); border: none; padding: 15px; border-radius: 0px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: 0.45px; orphans: 2; text-align: left; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">var AutodllWebpackpackPlugin = require('autodll-webpack-plugin'); plugins: [ new AutodllWebpackpackPlugin ({ inject: true, debugger: true, filename: '[name].js', path: './dll', entry: { vendor: ['vue'] } }) ]复制代码</pre>
tips: inject
为 true,插件会自动把打包出来的第三方库文件插入到 HTML。 filename
是打包后文件的名称。 path
是打包后的路径。 entry
是入口, vendor
是你指定的名称,数组内容就是要打包的第三方库的名称,不要写全路径,Webpack 会自动去 node_modules
中找到的。
- 提取公共代码
在 webpack.base.conf.js的 plugins 属性中添加如下插件对象
<pre style="box-sizing: border-box; outline-style: none; font-family: Menlo, Monaco, Consolas, "Courier New", monospace; font-size: 12px; margin: 0px -15px; overflow: auto; display: block; color: rgb(68, 68, 68); background-color: rgb(249, 249, 249); border-width: 1px 0px; border-right-style: initial; border-left-style: initial; border-right-color: initial; border-left-color: initial; border-image: initial; border-top-style: solid; border-top-color: rgb(240, 240, 240); border-bottom-style: solid; border-bottom-color: rgb(240, 240, 240); padding: 10px 15px; border-radius: 0px;">new webpack.optimize.SplitChunksPlugin()复制代码</pre>
- 打包时压缩js和css
下载optimize-css-assets-webpack-plugin和uglifyjs-webpack-plugin
<pre class="prettyprint prettyprinted" style="box-sizing: border-box; outline-style: none; font-family: Menlo, Monaco, Consolas, "Courier New", monospace; font-size: 12px; margin: 0px -15px 15px; overflow: auto; display: block; color: rgb(68, 68, 68); background-color: rgb(249, 249, 249); border: none; padding: 15px; border-radius: 0px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: 0.45px; orphans: 2; text-align: left; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">npm i uglifyjs-webpack-plugin uglifyjs-webpack-plugin -D复制代码</pre>
在webpack.prod.conf.js中分别引入optimize-css-assets-webpack-plugin和uglifyjs-webpack-plugin并增加optimization
<pre class="prettyprint prettyprinted" style="box-sizing: border-box; outline-style: none; font-family: Menlo, Monaco, Consolas, "Courier New", monospace; font-size: 12px; margin: 0px -15px 15px; overflow: auto; display: block; color: rgb(68, 68, 68); background-color: rgb(249, 249, 249); border: none; padding: 15px; border-radius: 0px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: 0.45px; orphans: 2; text-align: left; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">var OptimizeCSSAssetsPlugin = require("optimize-css-assets-webpack-plugin"); var UglifyJsPlugin = require("uglifyjs-webpack-plugin"); // ...省略号
optimization: { minimizer: [ // 压缩JS new UglifyJsPlugin({ uglifyOptions: { compress: { warnings: false, // 去除警告 drop_debugger: true, // 去除debugger drop_console: true // 去除console.log }, }, cache: true, // 开启缓存 parallel: true, // 平行压缩 sourceMap: false // set to true if you want JS source maps }), // 压缩css new OptimizeCSSAssetsPlugin({}) ] },复制代码</pre>
- css自动加前缀
下载postcss-loader 和autoprefixer
<pre style="box-sizing: border-box; outline-style: none; font-family: Menlo, Monaco, Consolas, "Courier New", monospace; font-size: 12px; margin: 0px -15px 15px; overflow: auto; display: block; color: rgb(68, 68, 68); background-color: rgb(249, 249, 249); border-width: 1px 0px; border-right-style: initial; border-left-style: initial; border-right-color: initial; border-left-color: initial; border-image: initial; border-top-style: solid; border-top-color: rgb(240, 240, 240); border-bottom-style: solid; border-bottom-color: rgb(240, 240, 240); padding: 10px 15px; border-radius: 0px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: 0.45px; orphans: 2; text-align: left; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">npm i postcss-loader autoprefixer -D复制代码</pre>
分别在webpack.dev.conf.js和webpack.prod.conf.js的use中添加 postcss-loader
<pre style="box-sizing: border-box; outline-style: none; font-family: Menlo, Monaco, Consolas, "Courier New", monospace; font-size: 12px; margin: 0px -15px 15px; overflow: auto; display: block; color: rgb(68, 68, 68); background-color: rgb(249, 249, 249); border-width: 1px 0px; border-right-style: initial; border-left-style: initial; border-right-color: initial; border-left-color: initial; border-image: initial; border-top-style: solid; border-top-color: rgb(240, 240, 240); border-bottom-style: solid; border-bottom-color: rgb(240, 240, 240); padding: 10px 15px; border-radius: 0px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: 0.45px; orphans: 2; text-align: left; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">use: [
'postcss-loader'
