Following is my webpack configurations file. I am using webpack 2.3.1 with dynamic routing of react-router. Hope it helps you.

var path = require('path');
var webpack = require('webpack');
var package=require('./package.json');
var config = require('./config');
var ManifestPlugin = require('webpack-manifest-plugin');


const ExtractTextPlugin = require('extract-text-webpack-plugin');
var getPlugins = function(){
  var pluginsList = [
    new webpack.optimize.CommonsChunkPlugin({
      name: 'vendor',
      minChunks: Infinity,
      filename: 'vendor.bundle_[hash].js'
    }),

    new webpack.DefinePlugin({
      "process.env": {
         NODE_ENV: JSON.stringify("production")
       }
    }),
    new webpack.NamedModulesPlugin(),
    new ManifestPlugin({
      fileName: 'build-manifest.json'
    })
  ];
    pluginsList.push(new webpack.LoaderOptionsPlugin({
      minimize: true,
      debug: false
    }));
    pluginsList.push(new webpack.optimize.UglifyJsPlugin({
      compress: {
        warnings: false
      },
      output: {
        comments: false
      },
      sourceMap: false,
      minimize: true
    }));
  return pluginsList;
}



module.exports = {
  cache: true,
  output: {
    path:path.join(__dirname, "dist/js"),
    filename: "[name]_[hash].js",
    chunkFilename:"[name]_[hash].js",
    publicPath:config.envConfig.JS_ASSETS_PATH
  },
  devServer: {
    contentBase: path.join(__dirname, "dist"),
    compress: true,
    port: 8080
  },

  entry: {
    index: [
      package.paths.app
    ],
    vendor: [
      'react', 'react-dom','phrontend',
      'react-ga'
    ]
  },
  plugins: getPlugins(),
  target: 'web',

  module: {
    rules: [
      {
        test: /.jsx?$/,
        exclude: /node_modules/,
        use: [{
          loader: 'babel-loader',
        }]
      }
    ]
  },
};
