最近搞vue，用的vue-cli，快速构建开发环境，当然核心还是集成的webpack。之前自己做react的webpack环境配置总觉得差强人意，于是就把vue-cli的迁移过来，感觉还是不错的。对应一般开发需要，下面需要修改的就在build和config目录下的几个文件中
从webpack.base.conf.js 文件开始，无论生产环境还是开发环境都以这个为基础的，
module.exports = {
entry: {
app: ['./src/js/index.js'],//入口文件
babel: ['babel-polyfill'] //babel-polyfill 和redux 单独打包减小app.js 的打包体积 用于配合externals
redux: ['redux','react-redux'],},output: {
path: config.build.assetsRoot,filename: '[name].js',publicPath: process.env.NODE_ENV === 'production'
? config.build.assetsPublicPath
: config.dev.assetsPublicPath,libraryTarget: 'umd' //用于外部引入的 react.js 等
},resolve: {
extensions: ['.js','.json'],symlinks: false
},module: {
rules: [
{
test: /\.js$/,loader: 'babel-loader',include: [resolve('src'),resolve('test')],exclude:[resolve('node_modules')],//在node_modules的文件不被babel理会
query: {
presets: ['react','stage-2']
}
},{
test: /\.(png|jpe?g|gif|svg)(\?.*)?$/,loader: 'url-loader',options: {
limit: 10000,name: utils.assetsPath('img/[name].[hash:7].[ext]'),}
},{
test: /\.(mp4|webm|ogg|mp3|wav|flac|aac)(\?.*)?$/,name: utils.assetsPath('media/[name].[hash:7].[ext]')
}
},{
test: /\.(woff2?|eot|ttf|otf)(\?.*)?$/,name: utils.assetsPath('fonts/[name].[hash:7].[ext]')
}
},// {
// test: /\.less$/,// use: ExtractTextPlugin.extract({ use: extractCssLoaders,fallback: 'style-loader' }),// }
]
},// 配置全局使用
plugins: [
new webpack.ProvidePlugin({
"React": "react","ReactDOM": "react-dom","_": "lodash","classnames":"classnames"
}),//extract css into its own file
new ExtractTextPlugin({
filename: utils.assetsPath('css/[name].[contenthash].css')
}),],// 单独提取出 react 减小打包文件大小
externals: {
'react-router': {
amd: 'react-router',root: 'ReactRouter',commonjs: 'react-router',commonjs2: 'react-router'
},react: {
amd: 'react',root: 'React',commonjs: 'react',commonjs2: 'react'
},'react-dom': {
amd: 'react-dom',root: 'ReactDOM',commonjs: 'react-dom',commonjs2: 'react-dom'
}
}
}
然后再 util.js 文件里，主要就在cssLoaders
exports.cssLoaders = function (options) {
options = options || {}
var cssLoader = {
loader: 'css-loader',options: {
minimize: process.env.NODE_ENV === 'production',sourceMap: options.sourceMap,modules: true,localIdentName: '[local]--[hash:base64:6]',//class 名字 代替
}
}
// generate loader string to be used with extract text plugin
function generateLoaders(loader,loaderOptions) {
var loaders = [cssLoader];
if (loader) {
loaders.push({
loader: loader + '-loader',options: Object.assign({},loaderOptions,{
sourceMap: options.sourceMap
})
})
}
// Extract CSS when that option is specified
//(which is the case during production build)
if (options.extract) {
return ExtractTextPlugin.extract({
use: loaders,publicPath: '../../',//解决 build css bg img 加载路径不对问题
fallback: 'react-style-loader' // 修改vue-style-loader
})
} else {
return ['react-style-loader'].concat(loaders)
}
}
// https://vue-loader.vuejs.org/en/configurations/extract-css.html
return {
css: generateLoaders(),postcss: generateLoaders(),less: generateLoaders('less'),sass: generateLoaders('sass',{ indentedSyntax: true }),scss: generateLoaders('sass'),stylus: generateLoaders('stylus'),styl: generateLoaders('stylus')
}
}
webpack.prod.conf 生产环境的修改，打包时，redux，和babel-polyfill 分离打包配置 配合 webpack.base.conf.js中entry修改
new webpack.optimize.CommonsChunkPlugin({
name: ['app','redux','babel'],//单独提取打包
filename: './static/js/[name].js',minChunks: ({resource}) => {
resource &&
/\.js$/.test(resource) &&
resource.indexOf(
path.join(__dirname,'../node_modules')
) === 0
}
}),// extract webpack runtime and module manifest to its own file in order to
// prevent vendor hash from being updated whenever app bundle is updated
new webpack.optimize.CommonsChunkPlugin({
name: 'manifest',chunks: ['app','babel']
}),
webpack.dev.conf.js和webpack.prod.conf.js 有同一个地方修要， 用于在inde.html上写入外部js
new HtmlWebpackPlugin({
title: config.title,filename: 'index.html',template: 'index.ejs',//修改模板类型 为ejs
inject: true,js: config.externalsJs_dev // 开发环境是config.externalsJs_prod
}),
当然config.externalsJs_dev 配置到了config/index.js 中
// 提取出的文件链接 externalsJs_dev:[ 'https://cdn.bootcss.com/react/16.0.0/umd/react.development.js','https://cdn.bootcss.com/react-dom/16.0.0/umd/react-dom.development.js','https://cdn.bootcss.com/react-router/4.2.0/react-router.js' ],externalsJs_prod: [ 'https://cdn.bootcss.com/react/16.0.0/umd/react.production.min.js','https://cdn.bootcss.com/react-dom/16.0.0/umd/react-dom.production.min.js','https://cdn.bootcss.com/react-router/4.2.0/react-router.min.js' ],title: 'react-redux-demo' //模板标题删除项目 根目录下的index.html 改为index.ejs， 内容如下
<!DOCTYPE html>
<html lang="en">
<head>
<Meta charset="UTF-8">
<title><%= htmlWebpackPlugin.options.title %></title>
</head>
<body>
<div id="root"></div>
<% for (var i = 0,item; item = htmlWebpackPlugin.options.js[i++];) { %>
<script type="text/javascript" src="<%= item %>"></script>
<% } %>
</body>
</html>目录结构如下 包括打包
运行一下npm run build --report=true 看看打包分析， 暂时未集成babel-runtime
是否要集成babel-runtime 需要修改.babelrc 文件中
"plugins": ["transform-runtime"],取消此行的注释， 打包分析如下
