react hot loader not updating the changes

Question

I am using react-hot-loader v3 but it is not working. It listens for the update on the server but do not show the changes instead i get warning as

log-apply-result.js?d762:11 [HMR] The following modules couldn't be hot updated: (They would need a full reload!)

Below is my webpack configuration

webpack.local.config.js

var path = require("path")
var webpack = require('webpack')
var BundleTracker = require('webpack-bundle-tracker')

var config = require('./webpack.base.config.js')
var localSettings = require('./webpack.local-settings.js')

var ip = localSettings.ip

config.devtool = "#eval-source-map"

config.ip = ip

// Use webpack dev server
config.entry = {
  App: [
    'webpack-dev-server/client?http://' + ip + ':3000',
    'webpack/hot/only-dev-server',
    'react-hot-loader/patch',
    './reactjs/App',
  ]
}

// override django's STATIC_URL for webpack bundles
config.output.publicPath = 'http://' + ip + ':3000' + '/assets/bundles/'

// Add HotModuleReplacementPlugin and BundleTracker plugins
config.plugins = config.plugins.concat([
  new webpack.HotModuleReplacementPlugin(),
  new webpack.NoErrorsPlugin(),
  new BundleTracker({filename: './webpack-stats-local.json'}),
  new webpack.DefinePlugin({
    'process.env': {
      'NODE_ENV': JSON.stringify('development'),
      'BASE_API_URL': JSON.stringify('http://' + ip + ':8000/api/v1/'),
  }}),

])

// Add a loader for JSX files with react-hot enabled
config.module.loaders.push(
  { test: /\.jsx?$/, exclude: /node_modules/, loaders: ['babel'] }
)

module.exports = config

server.js

var webpack = require('webpack')
var WebpackDevServer = require('webpack-dev-server')
var config = require('./webpack.local.config')

new WebpackDevServer(webpack(config), {
  publicPath: config.output.publicPath,
  hot: true,
  inline: true,
  historyApiFallback: true,
  quiet: false,
}).listen(3000, config.ip, function (err) {
  if (err) {
    console.log(err);
  }

  console.log('Listening at ' + config.ip + ':3000');
});

and my .babelrc

{
  "presets": ["es2015", "react", "stage-0"],
  "plugins": [
    ["react-hot-loader/babel", "transform-decorators-legacy"],
  ]
}

"react-hot-loader": "^3.0.0-beta.6",

"webpack": "^1.13.3",

"webpack-bundle-tracker": "^0.1.0",

"webpack-dev-server": "^1.16.2",

"webpack-loader": "^0.0.1"

App.jsx

render(<Change />, document.getElementById('app'))

For react-hot-loader v3 you need to explicitly use the hot module replacement api of webpack as described in the docs here (Also posted by Izhaki).

For instance,

import React from 'react'
import ReactDOM from 'react-dom'
import { AppContainer } from 'react-hot-loader'
import App from './containers/App'

ReactDOM.render(
  <AppContainer>
    <App/>
  </AppContainer>,
  document.getElementById('root')
);

// Hot Module Replacement API
if (module.hot) {
  module.hot.accept('./containers/App', () => {
    const NextApp = require('./containers/App').default;
    ReactDOM.render(
      <AppContainer>
        <NextApp/>
      </AppContainer>,
      document.getElementById('root')
    );
  });
}
