注意几点：

1、package.json中的依赖react配置的是0.13，手动改成0.14

2、devServer.js 中写死了页面为index.html，董express可以改改

以下是webpack.config.js

var path = require('path');
var webpack = require('webpack');

module.exports = {
  devtool: 'eval',entry: [
    'webpack-hot-middleware/client','./src/index'
  ],output: {
    path: path.join(__dirname,'dist'),filename: 'bundle.js',publicPath: '/static/'
  },plugins: [
    new webpack.HotModuleReplacementPlugin(),new webpack.NoErrorsPlugin()
  ],module: {
    loaders: [{
      test: /\.js$/,loaders: ['babel'],include: path.join(__dirname,'src')
    }]
  }
};
