webpack react的基本配置

本文为方便快速上手做了简单介绍。细节问题务必参看提供的链接。Word is cheap ，show me the code。

pakage.json

  "name": "react-demo1",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "repository": {
    "type": "git",
    "url": "git+https://github.com/lance10030/react-demo1.git"
  },

  },
  "homepage": "https://github.com/lance10030/react-demo1#readme",
  "devDependencies": {
    "babel-core": "^6.24.1",
    "babel-loader": "^7.0.0",
    "babel-preset-es2015": "^6.24.1",
    "babel-preset-react": "^6.24.1",
    "css-loader": "^0.28.0",
    "react": "^15.5.4",
    "react-dom": "^15.5.4",
    "style-loader": "^0.16.1",
    "webpack": "^2.4.1"
  }
}

webpack.config.js

module.exports = {
    entry: __dirname + '/src/main.js',//文件入口
    output: {
        path:__dirname + '/build',//出口文件位置
        filename:'bundle.js'      //出口文件名字
    },
    module:{
        loaders:[
            {
                test:/\.jsx?$/,
                loader:'babel-loader',
                exclude:/node_module/
            },
            {
                test: /\.css$/,
                loader: "style-loader!css-loader?modules"
            },
        ]
    }
};

babelrc(http://www.ruanyifeng.com/blog/2016/01/babel.html)

配置转码的规则:react项目需要配置两个，一个是react本身需要的转码规则，二是es6语法转到es5的语法；

{
  "presets":["react","es2015"]
}

与配置对应的文件目录结构：

-build
–bundle.js
-index.html
-babelrc
-node_modules
-pakage.json
-src
–components
–main.js
–main.css
-webpack.config.js

推荐设置1：样式与组件的模块化搭配

css_modules,在style-loader后面打开该功能：？modules。支持引入同一文件中的其他的类。也支持引入其他文件中的类。更多介绍，以及使用方法参考：http://www.ruanyifeng.com/blog/2016/06/css_modules.html

 {
    test: /\.css$/,
    loader: "style-loader!css-loader?modules"
 },

main.js

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

let Item1 = React.createClass({
    render:function () {
        return (
            <div >
                hello world!
            </div>
        )
    }
});
ReactDOM.render(
    <Item1/>,
    document.getElementById('all')
);

打开浏览器看到hello world 说明配置成功
