一分钟搭建Webpack+react+es6框架

最近react刷屏的厉害，而随着它一起走进我们视野的还有webpack，webpack只是个工具，为什么如此火呢？因为简单好了不废话。

?

直接进入正题：

打开命令行工具：

　　

npm install -g webpack
npm install -g webpack-dev-server

mkdir webpack-react-es6
cd webpack-react-es6
npm init
# 一直点回车 如果懒得填一些信息

　打开package.json 复制以下代码：

{
  "name": "react-es6-webpack",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "start": "webpack-dev-server --hot --progress --colors",
    "build": "webpack --progress --colors"
  },
  "author": "",
  "license": "ISC",
  "devDependencies": {
    "babel-core": "^6.7.2",
    "babel-loader": "^6.2.4",
    "babel-plugin-react-transform": "^2.0.2",
    "babel-preset-es2015": "^6.6.0",
    "babel-preset-react": "^6.5.0",
    "css-loader": "^0.23.1",
    "file-loader": "^0.8.5",
    "html-webpack-plugin": "^2.10.0",
    "react": "^0.14.7",
    "react-hot-loader": "^1.3.0",
    "react-transform-hmr": "^1.0.4",
    "sass-loader": "^3.2.0",
    "style-loader": "^0.13.0",
    "url-loader": "^0.5.7",
    "webpack": "^1.12.14",
    "webpack-dev-server": "^1.14.1"
  }
}

　创建webpack.config.js，复制以下代码：

 var  path = require('path' );
  var  webpack = require('webpack' );
  var  ROOT_PATH =  path.resolve(__dirname);
  var  APP_PATH = path.resolve(ROOT_PATH, 'app' );
  var  BUILD_PATH = path.resolve(ROOT_PATH, 'build' );
  //   var htmlWebpackPlugin =  require('html-webpack-plugin'); 
 
module.exports  =  {
    entry: [
       'webpack/hot/only-dev-server' ,
       "./app/index.js" 
    ],
    output: {
        path: BUILD_PATH,
        filename:  "bundle.js" 
    },
    module: {
        loaders: [
            {
              test:  /\.js$/ ,
              exclude:  /node_modules/ ,
              loader:  "babel-loader" ,
              query:
                {
                  presets:[ 'react','es2015' ]
                }
            }, {
                test:  /\.scss$/ ,
                loaders: [ 'style', 'css', 'sass' ],
                include: APP_PATH
            }, {
                test:  /\.(png|jpg)$/ ,
                loader:  'url?limit=40000' 
            }
        ]
    },
    resolve:{
        extensions:[ '','.js','.json' ]
    },
    devServer: {
        hot:   true  ,
        inline:   true  
    },
    plugins: [
        new   webpack.NoErrorsPlugin(),
        new   webpack.HotModuleReplacementPlugin()
    ]
}; 

根目录下创建index.html，为了调试用：

 <!  doctype html  > 
 <  html   lang  ="en"  > 
   <  head  > 
     <  meta   charset  ="utf-8"  > 
     <  meta   name  ="viewport"   content  ="width=device-width,initial-scale=1"  > 
     <  title  > New React App </  title  > 
   </  head  > 
   <  body  > 
     <  div   id  ="content"  ></  div  > 
     <  script   src  ="bundle.js"  ></  script  > 
   </  body  > 
 </  html  > 

根目录下创建app文件夹，新建index.js

import React from 'react' ;
import ReactDOM from  'react-dom' ;

let App  =  React.createClass({
  render() {
        return (<h1>Hello, world!</h1>);
   }
});

ReactDOM.render( <App/>, document.getElementById('content'));

　

最后在根目录下敲命令npm install,安心等待就ok，不过有很大的可能部分模块安装失败，比如node-sass，比较顽固，需要反复安装多次。

如果实在安装不成功，就直接下载http://pan.baidu测试数据/s/1bnYgWgv。
