cli3全面配置详解(2)

还可以开启比gzip体验更好的Zopfli压缩详见https://webpack.js.org/plugins/compression-webpack-plugin

npm i --save-dev @gfx/zopfli brotli-webpack-plugin

const CompressionWebpackPlugin = require('compression-webpack-plugin'); const zopfli = require("@gfx/zopfli"); const BrotliPlugin = require("brotli-webpack-plugin"); const productionGzipExtensions = /\.(js|css|json|txt|html|ico|svg)(\?.*)?$/i; module.exports = { configureWebpack: config => { if (IS_PROD) { const plugins = []; plugins.push( new CompressionWebpackPlugin({ algorithm(input, compressionOptions, callback) { return zopfli.gzip(input, compressionOptions, callback); }, compressionOptions: { numiterations: 15 }, minRatio: 0.99, test: productionGzipExtensions }) ); plugins.push( new BrotliPlugin({ test: productionGzipExtensions, minRatio: 0.99 }) ); config.plugins = [ ...config.plugins, ...plugins ]; } } }

为sass提供全局样式，以及全局变量

可以通过在main.js中Vue.prototype.$src = process.env.VUE_APP_SRC;挂载环境变量中的配置信息，然后在js中使用$src访问。

css中可以使用注入sass变量访问环境变量中的配置信息

module.exports = { css: { modules: false, extract: IS_PROD, sourceMap: false, loaderOptions: { sass: { // 向全局sass样式传入共享的全局变量 data: `@import "~assets/scss/variables.scss";$src: "${process.env.VUE_APP_SRC}";` } } } }

在scss中引用

.home { background: url($src + '/images/500.png'); }

添加IE兼容

npm i --save @babel/polyfill

在main.js中添加

import '@babel/polyfill';

配置babel.config.js

const plugins = []; module.exports = { presets: [["@vue/app",{"useBuiltIns": "entry"}]], plugins: plugins };

完整配置

安装依赖

复制代码 代码如下:

npm i --save-dev compression-webpack-plugin babel-plugin-transform-remove-console @gfx/zopfli brotli-webpack-plugin

package.json

"scripts": { "serve": "vue-cli-service serve", "build": "vue-cli-service build", "analyz": "vue-cli-service build --mode analyz", "lint": "vue-cli-service lint" }

babel.config.js
