} View Code 2、通过webpackreactes6进行模拟 注可以fork我的github https://github.com/hjzgg/webpack-react/tree/master/webpackAndReact 当然可以从0开始... 1、首先为项目建立一个名字例如“webpackreact”, 建立src/step、src/css和build目录在项目根目录下建立package.json文件内容如下 {name: react-webpack,version: 1.0.0,description: webpack demo,main: index.js,scripts: {start: node server.js,dev: webpack-dev-server --port 8000 --devtool eval --progress --colors --hot --inline,build-before: webpack --display-error-details --progress --colors -p,build: webpack --config webpack.build.config.js --display-error-details --progress --colors,build-watch: webpack --display-error-details --progress --colors --watch --debug --devtool source-map --output-pathinfo,test: echo \Error: no test specified\ exit 1},keywords: [react,webpack],author: hjzgg,devDependencies: {babel-core: ^6.3.21,babel-loader: ^6.2.4,babel-preset-es2015: ^6.3.13,babel-preset-react: ^6.3.13,css-loader: ~0.16.0,style-loader: ~0.12.3,react: ^0.14.3,react-hot-loader: ^1.3.0,react-router: ^1.0.2,extract-text-webpack-plugin: ^0.8.2,webpack: ^1.12.9,webpack-dev-server: ^1.14.0},dependencies: {lodash: ^3.9.3,react: ^0.14.3,react-dom: ^0.14.3}
} View Code 2、第二步就是创建我们webpack的配置文件webpack.config.js var webpack require(webpack);
module.exports {entry: [webpack/hot/only-dev-server,./src/step/app.js],output: {path: ./build,filename: bundle.js},module: {loaders: [{test: /\.js?$/, exclude: /node_modules/, loaders: [react-hot,babel-loader?presets[]react,presets[]es2015] },{ test: /\.css$/, loader: style!css}]},resolve:{extensions:[,.js,.json]},plugins: [new webpack.NoErrorsPlugin()]

} View Code 8、在项目根目录下打开bash执行npm install, 等待执行完毕项目的根目录下会多出node_modules文件夹这是项目所需要的一些依赖文件。 9、最后npm run dev将项目跑起来... 3、css-loader和style-loader webpack可以很方便的帮助我们导入css文件需要我们下载css的loader然后在webpack.config.js中配置这里已经配置好了。然后在js文件直接import xxx.css就可以直接使用css样式了。 引用css的另一个办法就是在入口文件index.html中通过link .../来实现也可以达到目的。当然还是推荐前者。 4、配置问题 关于工程依赖工程启动es6解析等一些配置还是要好好研究一下package.json和webpack.config.js这两个文件了请看看下面的文章 http://www.cnblogs.com/skylar/p/React-Webpack-ES6.html 三、demo下载 https://github.com/hjzgg/webpack-react 转载于:https://www.cnblogs.com/hujunzheng/p/5538293.html
