How to proxy index.html with react-transform

server.js

var express = require('express');
var webpack = require('webpack');
var httpProxy = require('http-proxy');
var proxy = new httpProxy.createProxyServer();
var config = require('./webpack.config');

var app = express();
var compiler = webpack(config);

app.use(require('webpack-dev-middleware')(compiler, {
  noInfo: true,
  publicPath: config.output.publicPath
}));

app.use(require('webpack-hot-middleware')(compiler));

if (config.proxy) {
  var paths = Object.keys(config.proxy);
  paths.forEach(function (path) {
    var proxyOptions;
    if (typeof config.proxy[path] === 'string') {
      proxyOptions = {target: config.proxy[path], ws: true};
    } else {
      proxyOptions = config.proxy[path];
    }
    app.all(path, function (req, res) {
      proxy.web(req, res, proxyOptions);
    });
  });
}

app.listen(3000, 'localhost', function(err) {
  if (err) {
    console.log(err);
    return;
  }

  console.log('Listening at http://localhost:3000');
});

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')
    }]
  },
  proxy: {
    '*': 'http://mybackendserver.com/'
  }
};
