✅ 配置多环境变量
通过在package.json里的 scripts 配置项中添加--mode xxx 来选择不同环境
只有以 VUE_APP 开头的变量会被 webpack.DefinePlugin 静态嵌入到客户端侧的包中,代码中可以通过 process.env.VUE_APP_BASE_API 访问
NODE_ENV 和 BASE_URL 是两个特殊变量,在代码中始终可用
配置
在项目根目录中新建.env, .env.production, .env.analyz等文件
- .env
serve 默认的本地开发环境配置
NODE_ENV = 'development'
BASE_URL = './'
VUE_APP_PUBLIC_PATH = './'
VUE_APP_API = 'https://test.staven630.com/api'
- .env.production
build 默认的环境配置
NODE_ENV = 'production'
BASE_URL = 'https://prod.staven630.com/'
VUE_APP_PUBLIC_PATH = 'https://prod.oss.com/staven-blog'
VUE_APP_API = 'https://prod.staven630.com/api'
ACCESS_KEY_ID = 'xxxxxxxxxxxxx'
ACCESS_KEY_SECRET = 'xxxxxxxxxxxxx'
REGION = 'oss-cn-hangzhou'
BUCKET = 'staven-prod'
PREFIX = 'staven-blog'
- .env.analyz
自定义build环境配置
NODE_ENV = 'production'
BASE_URL = 'https://prod.staven630.com/'
VUE_APP_PUBLIC_PATH = 'https://prod.oss.com/staven-blog'
VUE_APP_API = 'https://prod.staven630.com/api'
ACCESS_KEY_ID = 'xxxxxxxxxxxxx'
ACCESS_KEY_SECRET = 'xxxxxxxxxxxxx'
REGION = 'oss-cn-hangzhou'
BUCKET = 'staven-prod'
PREFIX = 'staven-blog'
IS_ANALYZE = true
修改 package.json
"scripts": {
"serve": "vue-cli-service serve",
"build": "vue-cli-service build",
"analyz": "vue-cli-service build --mode analyze",
"lint": "vue-cli-service lint"
}
使用环境变量
<template>
<div class="home">
<!-- template中使用环境变量 -->
{{ api }}
</div>
</template>
<script>
export default {
name: "home",
data() {
return {
api: process.env.VUE_APP_API
};
},
mounted() {
// js代码中使用环境变量
console.log("BASE_URL", process.env.BASE_URL);
console.log("VUE_APP_API", process.env.VUE_APP_API);
}
};
</script>
✅ 配置基础 vue.config.js
const IS_PROD = ["production", "prod"].includes(process.env.NODE_ENV);
module.exports = {
publicPath: IS_PROD ? process.env.VUE_APP_PUBLIC_PATH : "./", // 默认'/',部署应用包时的基本 URL
// outputDir: process.env.outputDir || 'dist', // 'dist', 生产环境构建文件的目录
// assetsDir: "", // 相对于outputDir的静态资源(js、css、img、fonts)目录
lintOnSave: false,
runtimeCompiler: true, // 是否使用包含运行时编译器的 Vue 构建版本
productionSourceMap: !IS_PROD, // 生产环境的 source map
parallel: require("os").cpus().length > 1,
pwa: {}
};
✅ 配置proxy代理解决跨域问题
假设mock接口为https://www.easy-mock.com/mock/5bc75b55dc36971c160cad1b/sheets/1
module.exports = {
devServer: {
// overlay: { // 让浏览器 overlay 同时显示警告和错误
// warnings: true,
// errors: true
// },
// open: false, // 是否打开浏览器
// host: "localhost",
// port: "8080", // 代理断就
// https: false,
// hotOnly: false, // 热更新
proxy: {
"/api": {
target:
"https://www.easy-mock.com/mock/5bc75b55dc36971c160cad1b/sheets", // 目标代理接口地址
secure: false,
changeOrigin: true, // 开启代理,在本地创建一个虚拟服务端
// ws: true, // 是否启用websockets
pathRewrite: {
"^/api": "/"
}
}
}
}
};
访问
<script>
import axios from "axios";
export default {
mounted() {
axios.get("/api/1").then(res => {
console.log(res);
});
}
};
</script>
✅ 修复 HMR(热更新)失效
module.exports = {
chainWebpack: config => {
// 修复HMR
config.resolve.symlinks(true);
}
}
✅ 修复 Lazy loading routes Error: Cyclic dependency https://github.com/vuejs/vue-cli/issues/1669
module.exports = {
chainWebpack: config => {
config.plugin('html').tap(args => {
args[0].chunksSortMode = 'none';
return args;
});
}
}
✅ 添加别名alias
const path = require('path');
const resolve = (dir) => path.join(__dirname, dir);
const IS_PROD = ['production', 'prod'].includes(process.env.NODE_ENV);
module.exports = {
chainWebpack: config => {
// 添加别名
config.resolve.alias
.set('vue$', 'vue/dist/vue.esm.js')
.set('@', resolve('src'))
.set('@assets', resolve('src/assets'))
.set('@scss', resolve('src/assets/scss'))
.set('@components', resolve('src/components'))
.set('@plugins', resolve('src/plugins'))
.set('@views', resolve('src/views'))
.set('@router', resolve('src/router'))
.set('@store', resolve('src/store'))
.set('@layouts', resolve('src/layouts'))
.set('@static', resolve('src/static'));
}
}
✅ 压缩图片
npm i -D image-webpack-loader
module.exports = {
chainWebpack: config => {
config.module
.rule("images")
.use("image-webpack-loader")
.loader("image-webpack-loader")
.options({
mozjpeg: { progressive: true, quality: 65 },
optipng: { enabled: false },
pngquant: { quality: "65-90", speed: 4 },
gifsicle: { interlaced: false },
webp: { quality: 75 }
});
}
}
✅ 自动生成雪碧图
默认src/assets/icons中存放需要生成雪碧图的png文件。首次运行npm run serve/build会生成雪碧图,并在跟目录生成icons.json文件。再次运行命令时,会对比icons目录内文件与icons.json的匹配关系,确定是否需要再次执行webpack-spritesmith插件。
npm i -D webpack-spritesmith
const SpritesmithPlugin = require('webpack-spritesmith')
const path = require('path')
const fs = require('fs')
let has_sprite = true
try {
let result = fs.readFileSync(path.resolve(__dirname, './icons.json'), 'utf8')
result = JSON.parse(result)
const files = fs.readdirSync(path.resolve(__dirname, './src/assets/icons'))
if (files && files.length) {
has_sprite = files.some(item => {
let filename = item.toLocaleLowerCase().replace(/_/g, '-')
return !result[filename]
})
? true
: false
} else {
has_sprite = false
}
} catch (error) {}
// 雪碧图样式处理模板
const SpritesmithTemplate = function(data) {
// pc
let icons = {}
let tpl = `.ico {
display: inline-block;
background-image: url(${data.sprites[0].image});
background-size: ${data.spritesheet.width}px ${data.spritesheet.height}px;
}`
data.sprites.forEach(sprite => {
const name = '' + sprite.name.toLocaleLowerCase().replace(/_/g, '-')
icons[`${name}.png`] = true
tpl = `${tpl}
.ico-${name}{
width: ${sprite.width}px;
height: ${sprite.height}px;
background-position: ${sprite.offset_x}px ${sprite.offset_y}px;
}
`
})
fs.writeFile(
path.resolve(__dirname, './icons.json'),
JSON.stringify(icons, null, 2),
(err, data) => {}
)
return tpl
}
module.exports = {
configureWebpack: config => {
const plugins = []
if (has_sprite) {
plugins.push(
new SpritesmithPlugin({
src: {
cwd: path.resolve(__dirname, './src/assets/icons/'), // 图标根路径
glob: '**/*.png' // 匹配任意 png 图标
},
target: {
image: path.resolve(__dirname, './src/assets/images/sprites.png'), // 生成雪碧图目标路径与名称
// 设置生成CSS背景及其定位的文件或方式
css: [
[
path.resolve(__dirname, './src/assets/scss/sprites.scss'),
{
format: 'function_based_template'
}
]
]
},
customTemplates: {
function_based_template: SpritesmithTemplate
},
apiOptions: {
cssImageRef: '../images/sprites.png' // css文件中引用雪碧图的相对位置路径配置
},
spritesmithOptions: {
padding: 2
}
})
)
}
config.plugins = [...config.plugins, ...plugins]
}
}
✅ 去除多余无效的 css
- 方案一:@fullhuman/postcss-purgecss
npm i -D postcss-import @fullhuman/postcss-purgecss
更新 postcss.config.js
const autoprefixer = require('autoprefixer')
const postcssImport = require('postcss-import')
const purgecss = require('@fullhuman/postcss-purgecss')
const IS_PROD = ['production', 'prod'].includes(process.env.NODE_ENV)
let plugins = []
if (IS_PROD) {
plugins.push(postcssImport)
plugins.push(
purgecss({
content: [
'./layouts/**/*.vue',
'./components/**/*.vue',
'./pages/**/*.vue'
],
extractors: [
{
extractor: class Extractor {
static extract(content) {
const validSection = content.replace(
/<style([\s\S]*?)<\/style>+/gim,
''
)
return validSection..match(/[A-Za-z0-9-_/:]*[A-Za-z0-9-_/]+/g) || []
}
},
extensions: ['html', 'vue']
}
],
whitelist: ['html', 'body'],
whitelistPatterns: [/el-.*/, /-(leave|enter|appear)(|-(to|from|active))$/, /^(?!cursor-move).+-move$/, /^router-link(|-exact)-active$/],
whitelistPatternsChildren: [/^token/, /^pre/, /^code/]
})
)
}
module.exports = {
plugins: [...plugins, autoprefixer]
}
- 方案二:purgecss-webpack-plugin
npm i -D glob-all purgecss-webpack-plugin
const path = require("path");
const glob = require("glob-all");
const PurgecssPlugin = require("purgecss-webpack-plugin");
const resolve = dir => path.join(__dirname, dir);
const IS_PROD = ["production", "prod"].includes(process.env.NODE_ENV);
module.exports = {
configureWebpack: config => {
const plugins = [];
if (IS_PROD) {
plugins.push(
new PurgecssPlugin({
paths: glob.sync([resolve("./**/*.vue")]),
extractors: [
{
extractor: class Extractor {
static extract(content) {
const validSection = content.replace(
/<style([\s\S]*?)<\/style>+/gim,
""
);
return validSection..match(/[A-Za-z0-9-_/:]*[A-Za-z0-9-_/]+/g) || []
}
},
extensions: ["html", "vue"]
}
],
whitelist: ["html", "body"],
whitelistPatterns: [/el-.*/, /-(leave|enter|appear)(|-(to|from|active))$/, /^(?!cursor-move).+-move$/, /^router-link(|-exact)-active$/],
whitelistPatternsChildren: [/^token/, /^pre/, /^code/]
})
);
}
config.plugins = [...config.plugins, ...plugins];
}
};
✅ 添加打包分析
const BundleAnalyzerPlugin = require('webpack-bundle-analyzer').BundleAnalyzerPlugin;
module.exports = {
chainWebpack: config => {
// 打包分析
if (process.env.IS_ANALYZ) {
config.plugin('webpack-report')
.use(BundleAnalyzerPlugin, [{
analyzerMode: 'static',
}]);
}
}
}
需要添加.env.analyz文件
NODE_ENV = 'production'
IS_ANALYZE = true
package.json的scripts中添加
"analyz": "vue-cli-service build --mode analyze"
执行
npm run analyz
✅ 配置externals引入cdn资源
防止将某些 import 的包(package)打包到 bundle 中,而是在运行时(runtime)再去从外部获取这些扩展依赖
module.exports = {
configureWebpack: config => {
config.externals = {
vue: 'Vue',
'element-ui': 'ELEMENT',
'vue-router': 'VueRouter',
vuex: 'Vuex',
axios: 'axios'
}
},
chainWebpack: config => {
const cdn = {
// 访问https://unpkg.com/element-ui/lib/theme-chalk/index.css获取最新版本
css: ['//unpkg.com/[email protected]/lib/theme-chalk/index.css'],
js: [
'//unpkg.com/[email protected]/dist/vue.min.js', // 访问https://unpkg.com/vue/dist/vue.min.js获取最新版本
'//unpkg.com/[email protected]/dist/vue-router.min.js',
'//unpkg.com/[email protected]/dist/vuex.min.js',
'//unpkg.com/[email protected]/dist/axios.min.js',
'//unpkg.com/[email protected]/lib/index.js'
]
};
// html中添加cdn
config.plugin('html').tap(args => {
args[0].cdn = cdn
return args
})
}
}
在html中添加
<!-- 使用CDN的CSS文件 -->
<% for (var i in htmlWebpackPlugin.options.cdn &&
htmlWebpackPlugin.options.cdn.css) { %>
<link rel="stylesheet" href="<%= htmlWebpackPlugin.options.cdn.css[i] %>" />
<% } %>
<!-- 使用CDN的JS文件 -->
<% for (var i in htmlWebpackPlugin.options.cdn &&
htmlWebpackPlugin.options.cdn.js) { %>
<script
type="text/javascript"
src="<%= htmlWebpackPlugin.options.cdn.js[i] %>"
></script>
<% } %>
✅ 去掉 console.log
方法一:使用 babel-plugin-transform-remove-console 插件
npm i --D babel-plugin-transform-remove-console
在 babel.config.js 中配置
const IS_PROD = ["production", "prod"].includes(process.env.NODE_ENV);
const plugins = [];
if (IS_PROD) {
plugins.push("transform-remove-console");
}
module.exports = {
presets: ["@vue/app", { useBuiltIns: "entry" }],
plugins
};
方法二:
const UglifyJsPlugin = require('uglifyjs-webpack-plugin');
module.exports = {
configureWebpack: config => {
if (IS_PROD) {
const plugins = [];
plugins.push(
new UglifyJsPlugin({
uglifyOptions: {
compress: {
warnings: false,
drop_console: true,
drop_debugger: false,
pure_funcs: ['console.log']//移除console
}
},
sourceMap: false,
parallel: true
})
);
config.plugins = [
...config.plugins,
...plugins
];
}
}
}
如果使用uglifyjs-webpack-plugin会报错,可能存在node_modules中有些依赖需要babel转译。
而vue-cli的transpileDependencies配置默认为[], babel-loader 会忽略所有 node_modules 中的文件。如果你想要通过 Babel 显式转译一个依赖,可以在这个选项中列出来。配置需要转译的第三方库。
利用splitChunks单独打包第三方模块
const IS_PROD = ['production', 'prod'].includes(process.env.NODE_ENV)
module.exports = {
configureWebpack: config => {
if (IS_PROD) {
config.optimization = {
splitChunks: {
cacheGroups: {
libs: {
name: 'chunk-libs',
test: /[\\/]node_modules[\\/]/,
priority: 10,
chunks: 'initial'
},
elementUI: {
name: 'chunk-elementUI',
priority: 20,
test: /[\\/]node_modules[\\/]element-ui[\\/]/,
chunks: 'all'
}
}
}
}
}
},
chainWebpack: config => {
if (IS_PROD) {
config.optimization.delete('splitChunks')
}
return config
}
}
✅ 开启gzip压缩
npm i --D compression-webpack-plugin
const CompressionWebpackPlugin = require("compression-webpack-plugin");
const IS_PROD = ["production", "prod"].includes(process.env.NODE_ENV);
const productionGzipExtensions = /\.(js|css|json|txt|html|ico|svg)(\?.*)?$/i;
module.exports = {
configureWebpack: config => {
const plugins = [];
if (IS_PROD) {
plugins.push(
new CompressionWebpackPlugin({
filename: "[path].gz[query]",
algorithm: "gzip",
test: productionGzipExtensions,
threshold: 10240,
minRatio: 0.8
})
);
}
config.plugins = [...config.plugins, ...plugins];
}
};
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 IS_PROD = ["production", "prod"].includes(process.env.NODE_ENV);
const productionGzipExtensions = /\.(js|css|json|txt|html|ico|svg)(\?.*)?$/i;
module.exports = {
configureWebpack: config => {
const plugins = [];
if (IS_PROD) {
plugins.push(
new CompressionWebpackPlugin({
algorithm(input, compressionOptions, callback) {
return zopfli.gzip(input, compressionOptions, callback);
},
compressionOptions: {
numiterations: 15
},
minRatio: 0.99,
test: productionGzipExtensions
})
);
plugins.push(
new BrotliPlugin({
test: productionGzipExtensions,
minRatio: 0.99
})
);
}
config.plugins = [...config.plugins, ...plugins];
}
};
✅ 为 sass 提供全局样式,以及全局变量
可以通过在 main.js 中 Vue.prototype.$src = process.env.VUE_APP_PUBLIC_PATH;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 "@scss/config.scss";
@import "@scss/variables.scss";
@import "@scss/mixins.scss";
@import "@scss/utils.scss";
$src: "${process.env.VUE_APP_OSS_SRC}";
`
}
}
}
}
在 scss 中引用
.home {
background: url($src + '/images/500.png');
}
✅ 为 stylus 提供全局变量
npm i -D style-resources-loader
const path = require('path')
const resolve = dir => path.resolve(__dirname, dir)
const addStylusResource = rule => {
rule
.use('style-resouce')
.loader('style-resources-loader')
.options({
patterns: [resolve('src/assets/stylus/variable.styl')]
})
}
module.exports = {
chainWebpack: config => {
const types = ['vue-modules', 'vue', 'normal-modules', 'normal']
types.forEach(type =>
addStylusResource(config.module.rule('stylus').oneOf(type))
)
}
}
预渲染prerender-spa-plugin
npm i -D prerender-spa-plugin
const PrerenderSpaPlugin = require('prerender-spa-plugin')
const path = require('path')
const resolve = dir => path.join(__dirname, dir)
const IS_PROD = ['production', 'prod'].includes(process.env.NODE_ENV)
module.exports = {
configureWebpack: config => {
const plugins = []
if (IS_PROD) {
plugins.push(
new PrerenderSpaPlugin({
staticDir: resolve('dist'),
routes: ['/'],
postProcess(ctx) {
ctx.route = ctx.originalRoute
ctx.html = ctx.html
.split(/>[\s]+</gim)
.join('><')
if (ctx.route.endsWith('.html')) {
ctx.outputPath = path.join(
__dirname,
'dist',
ctx.route
)
}
return ctx
},
minify: {
collapseBooleanAttributes: true,
collapseWhitespace: true,
decodeEntities: true,
keepClosingSlash: true,
sortAttributes: true
},
renderer: new PrerenderSpaPlugin.PuppeteerRenderer({
// 需要注入一个值,这样就可以检测页面当前是否是预渲染的
inject: {},
headless: false,
// 视图组件是在API请求获取所有必要数据后呈现的,因此我们在dom中存在“data view”属性后创建页面快照
renderAfterDocumentEvent: 'render-event'
})
})
)
}
config.plugins = [...config.plugins, ...plugins]
}
}
mounted()中添加document.dispatchEvent(new Event('render-event'))
new Vue({
router,
store,
render: (h) => h(App),
mounted() {
document.dispatchEvent(new Event('render-event'))
}
}).$mount('#app')
✅ 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
};
✅ 文件上传 ali oss
开启文件上传 ali oss,需要将 publicPath 改成 ali oss 资源 url 前缀,也就是修改 VUE_APP_PUBLIC_PATH
npm i -D webpack-oss
const AliOssPlugin = require('webpack-oss');
module.exports = {
configureWebpack: config => {
if (IS_PROD) {
const plugins = [];
// 上传文件到oss
if (process.env.ACCESS_KEY_ID || process.env.ACCESS_KEY_SECRET || process.env.REGION || process.env.BUCKET || process.env.PREFIX) {
plugins.push(
new AliOssPlugin({
accessKeyId: process.env.ACCESS_KEY_ID,
accessKeySecret: process.env.ACCESS_KEY_SECRET,
region: process.env.REGION,
bucket: process.env.BUCKET,
prefix: process.env.PREFIX,
exclude: /.*\.html$/,
deleteAll: false
})
);
}
config.plugins = [
...config.plugins,
...plugins
];
}
}
}
✅ 完整配置
const path = require("path");
// const glob = require("glob-all");
// const PurgecssPlugin = require("purgecss-webpack-plugin");
const BundleAnalyzerPlugin = require("webpack-bundle-analyzer")
.BundleAnalyzerPlugin;
