vue-cli常用设置总结

基于vue-cli做了好几个项目了,想把一些自己的常用设置写出来,磨了好久,一看vue-cli3.0都快出来了,不能再磨了。。

路径相关

css内引用的资源

build -> utils.js
 // generate loader string to be used with extract text plugin
 function generateLoaders (loader, loaderOptions) {
  //less
  // Extract CSS when that option is specified
  // (which is the case during production build)
  if (options.extract) {
   return ExtractTextPlugin.extract({
    use: loaders,
    publicPath: '../../', //注意: 此处根据路径, 自动更改
    fallback: 'vue-style-loader'
   })
  } else {
   return ['vue-style-loader'].concat(loaders)
  }
 }

本地访问

config -> index.js
module.exports = {
 build: {
  //less
  //assetsPublicPath: '/',
  assetsPublicPath: './',
  //less
 },
 //less
}

调试相关

内网访问

config -> index.js

module.exports = {
 //less
 dev: {
  //less
  port: process.env.PORT || 8080,//可改端口
  host:'192.168.0.105',//不是8080端口可能需要指定host为本机IP
 }
}

跨域代理

config -> index.js
module.exports = {
 //less
 dev: {
  //less
  proxyTable: {
   '/AppHome': {
    target: 'http://192.168.0.211:2334',//接口域名
    changeOrigin: true,//是否跨域
    pathRewrite: {
     '^/AppHome': '/AppHome'//需要rewrite重写
    }
   }
  },
 }
}
config -> dev.env.js
module.exports = merge(prodEnv, {
 NODE_ENV: '"development"',
 API_HOST: '"AppHome/"' 
})
config -> prod.env.js
module.exports = {
 NODE_ENV: '"production"',
 API_HOST: '"http://xxx.xxx.com/AppHome/"' //生产环境改为绝对地址,免得路径错了
}
//调用
this.$http
  .post(process.env.API_HOST + "GetApproveTypeList", { ID: 0 })
  .then(data => {
  let $data = data.data;
  if ($data.IsSuccess) {
    this.list.push(...$data.Model);
  }
});

路由加载切换

异步加载可以加快首屏加载速度,但是在开发阶段会导致热加载变慢,所以根据NODE_ENV来判断,开发环境不使用异步

let _import
if (process.env.NODE_ENV === 'development') {
 _import = file => require('@/components/' + file + '.vue').default
}
if (process.env.NODE_ENV === 'production') {
 _import = file => () => import('@/components/' + file + '.vue')
}

routes: [
  {
    path: '/',
    name: 'Index',
    component: _import('Approve/Index'),
    meta: {
      level: 1
    }
  },
]

打包

dll打包

1、在build目录新建webpack.dll.conf.js

var path = require("path");
var webpack = require("webpack");
module.exports = {
  // 你想要打包的模块的数组
  entry: {
    vendor: ['vue/dist/vue.esm.js', //有些资源需要直接指定js,否则会重复打包
         'vuex',
         'axios',
         'vue-router'
        ]
  },
  output: {
    path: path.join(__dirname, '../static/js'), // 打包后文件输出的位置
    filename: '[name].dll.js',
    library: '[name]_library'
    // vendor.dll.js中暴露出的全局变量名。
  },
  plugins: [
    new webpack.DllPlugin({
      path: path.join(__dirname, '..', '[name]-manifest.json'),
      name: '[name]_library',
      context: __dirname
    }),
    // 压缩打包的文件
    new webpack.optimize.UglifyJsPlugin({
      compress: {
        warnings: false
      }
    })
  ]
};

2、在build目录下的webpack.prod.conf.js添加新插件

const webpackConfig = merge(baseWebpackConfig, {
  //less
 plugins: [
  //less
  new webpack.DllReferencePlugin({
   context: __dirname,
   manifest: require('../vendor-manifest.json')
  })
 ]
})

3、在项目根目录下的index.html内添加dll.js引用

<!DOCTYPE html>
<html>
 <head>
  <meta charset="utf-8">
  <title>title</title>
  <meta name="viewport" content="width=device-width, initial-scale=1.0">
 </head>
 <body>
  <div id="app"></div>
  <!-- built files will be auto injected -->
  <script src="/UploadFiles/2021-04-02/vendor.dll.js">

4、在项目根目录下的package.json内添加dll命令(顺便给build命令添加report),运行一次生成dll.js

 "scripts": {
  "dev": "node build/dev-server.js",
  "start": "npm run dev",
  "build": "node build/build.js --report",
  "dll": "webpack --config build//webpack.dll.conf.js"
 }

关闭SourceMap

config -> index.js
module.exports = {
 //less
 build: {
  //less
  productionSourceMap: false,
 },
}
