webpack4 + react 搭建多页面应用示例

webpack 升级到4之后还没好好的同步一个可实用的webpack架子，接下来用webpack4来搭建一个简单的react的多界面应用，废话不说 直接撸码

创建工程

webpack 配置

安装react + babel 依赖

$ npm i -D webpack@4.4.1 webpack-cli@2.0.13 webpack-dev-server@3.1.1 webpack-merge@4.1.2 babel-cli@6.26.0 babel-preset-env@1.6.1 babel-preset-react@6.24.1 babel-preset-react-hmre@1.1.1 babel-loader@7.1.4 file-loader@1.1.11 url-loader@1.0.1

webpack.base.conf.js(config -> webpack)

webpack.dev.conf.js

let config = merge(baseWebpackConfig,{
/设置开发环境/
mode: 'development',output: {
path: path.resolve(webpackFile.devDirectory),filename: 'js/[name].js',chunkFilename: "js/[name].js",publicPath: ''
},optimization: {
runtimeChunk: {
name: 'manifest'
},// 包拆分
splitChunks: {
cacheGroups: {
common: { // 项目的公共组件
chunks: "initial",name: "common",minChunks: 2,maxInitialRequests: 5,minSize: 0
},vendor: { // 第三方组件
test: /node_modules/,chunks: "initial",name: "vendor",priority: 10,enforce: true
}
}
}
},plugins: [
/设置热更新/
new webpack.HotModuleReplacementPlugin(),],module: {

test: /.(js|jsx)$/,use: [

]
},/设置api转发/

}
],/打开浏览器 并打开本项目网址/
after() {
opn('http://localhost:' + this.port);
}
}
});
module.exports = config;

webpack.prod.conf.js

let config = merge(baseWebpackConfig,{
/设置生产环境/
mode: 'production',output: {
path: path.resolve(webpackFile.proDirectory),filename: 'js/[name].[chunkhash:8].js',chunkFilename: "js/[name]-[id].[chunkhash:8].js",optimization: {
//包清单

// extract css into its own file
new ExtractTextPlugin('css/[name].[md5:contenthash:hex:8].css'),// Compress extracted CSS. We are using this plugin so that possible
// duplicated CSS from different components can be deduped.
new OptimizeCSSPlugin({
assetNameRegExp: /.css$/g,cssProcessor: require('cssnano'),cssProcessorOptions: {
discardComments: {removeAll: true},// 避免 cssnano 重新计算 z-index
safe: true
},canPrint: true
}),loader: 'babel-loader',exclude: /node_modules/,use: ExtractTextPlugin.extract({

})
},{
test: /.(png|jpg|gif|ttf|eot|woff|woff2|svg)$/,loader: 'url-loader?limit=8192&name=[name].[hash:8].[ext]&publicPath=' + webpackFile.resourcePrefix + '&outputPath=' + webpackFile.resource + '/'
},{
test: /.swf$/,loader: 'file?name=js/[name].[ext]'
}
]
}
});
let pages = entry;
for (let chunkName in pages) {
let conf = {
filename: chunkName + '.html',template: 'index.html',inject: true,title: webpackCom.titleFun(chunkName,pages[chunkName][1]),minify: {
removeComments: true,collapseWhitespace: true,removeAttributeQuotes: true
},chunks: ['manifest','vendor','common',chunkName],hash: false,chunksSortMode: 'dependency'
};
config.plugins.push(new HtmlWebpackPlugin(conf));
}
/ 清除 dist /
config.plugins.push(new CleanWebpackPlugin([webpackFile.proDirectory],{root: path.resolve(__dirname,'../../'),verbose: true,dry: false}));

/ 拷贝静态资源 /
copyArr.map(function (data) {
return config.plugins.push(data)
});

module.exports = config;

构建多界面

整体架构搭建起来之后

app -> component

); } } export default Index;

在config -> entry

然后直接执行 npm run create-dev 就会在devBuild 和 entryBuild 中添加一个新的demo.html 和 demo.js

开发环境小技巧

在开发环境添加cache-loader 可以提升在开发环境的编译速度
