首先是webpack的配置

const path = require('path');
const HtmlwebpackPlugin = require('html-webpack-plugin');
const merge = require('webpack-merge');
const webpack = require('webpack');
const CleanPlugin = require('clean-webpack-plugin');
const ExtractTextPlugin = require('extract-text-webpack-plugin');

const pkg = require('./package.json');

const TARGET = process.env.npm_lifecycle_event;
const PATHS = {
  app: path.join(__dirname, 'app'),
  build: path.join(__dirname, 'build'),
  style: path.join(__dirname, 'app/main.css'),
  test: path.join(__dirname, 'tests')
};
const ENV = {
  host: process.env.HOST || 'localhost',
  port: process.env.PORT || 8080
};

process.env.BABEL_ENV = TARGET;

const common = {
  entry: {
    app: PATHS.app
  },
  resolve: {
    extensions: ['', '.js', '.jsx']
  },
  output: {
    path: PATHS.build,
    filename: '[name].js'
  },
  module: {
    loaders: [
      {
        test: /\.jsx?$/,
        loaders: ['babel?cacheDirectory'],
        include: PATHS.app
      }
    ]
  },
  plugins: [
    new HtmlwebpackPlugin({
      template: 'node_modules/html-webpack-template/index.ejs',
      title: 'Kanban app',
      appMountId: 'app',
      inject: false
    })
  ]
};

if(TARGET === 'start' || !TARGET) {
  module.exports = merge(common, {
    entry: {
      style: PATHS.style
    },
    devtool: 'eval-source-map',
    devServer: {
      historyApiFallback: true,
      hot: true,
      inline: true,
      progress: true,

      // display only errors to reduce the amount of output
      stats: 'errors-only',

      // parse host and port from env so this is easy
      // to customize
      host: ENV.host,
      port: ENV.port
    },
    module: {
      loaders: [
        // Define development specific CSS setup
        {
          test: /\.css$/,
          loaders: ['style', 'css'],
          include: PATHS.app
        }
      ]
    },
    plugins: [
      new webpack.HotModuleReplacementPlugin()
    ]
  });
}

if(TARGET === 'build' || TARGET === 'stats') {
  module.exports = merge(common, {
    entry: {
      vendor: Object.keys(pkg.dependencies).filter(function(v) {
        // Exclude alt-utils as it won't work with this setup
        // due to the way the package has been designed
        // (no package.json main).
        return v !== 'alt-utils';
      }),
      style: PATHS.style
    },
    output: {
      path: PATHS.build,
      filename: '[name].[chunkhash].js',
      chunkFilename: '[chunkhash].js'
    },
    module: {
      loaders: [
        // Extract CSS during build
        {
          test: /\.css$/,
          loader: ExtractTextPlugin.extract('style', 'css'),
          include: PATHS.app
        }
      ]
    },
    plugins: [
      new CleanPlugin([PATHS.build]),
      // Output extracted CSS to a file
      new ExtractTextPlugin('styles.[chunkhash].css'),
      // Extract vendor and manifest files
      new webpack.optimize.CommonsChunkPlugin({
        names: ['vendor', 'manifest']
      }),
      // Setting DefinePlugin affects React library size!
      new webpack.DefinePlugin({
        'process.env.NODE_ENV': '"production"'
      }),
      new webpack.optimize.UglifyJsPlugin({
        compress: {
          warnings: false
        }
      })
    ]
  });
}

if(TARGET === 'test' || TARGET === 'tdd') {
  module.exports = merge(common, {
    devtool: 'inline-source-map',
    resolve: {
      alias: {
        'app': PATHS.app
      }
    },
    module: {
      preLoaders: [
        {
          test: /\.jsx?$/,
          loaders: ['isparta-instrumenter'],
          include: PATHS.app
        }
      ],
      loaders: [
        {
          test: /\.jsx?$/,
          loaders: ['babel?cacheDirectory'],
          include: PATHS.test
        }
      ]
    }
  });
}

然后是config.json的配置
