[Solved]-Webpack Hot Module Reloader not working with React Stateless Component-Reactjs

If it is still relevant and people have issues yet, there is a way, with the version 3 that is still in dev. I'll paste here my setup for package.json and the webpack.config.js files but if you want a working example here is the repo I created for this

package.json

{
  "name": "favesound-project",
  "version": "1.0.0",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1",
    "start": "webpack-dev-server --progress --colors --hot --config ./webpack.config.js"
  },

  },

  "description": ""
}

webpack.config.js

const webpack = require('webpack');

module.exports = {
    entry: [
        'react-hot-loader/patch',
        'webpack-dev-server/client?http://localhost:8080',
        'webpack/hot/only-dev-server',
        './src/index.js'
    ],
    module: {
        loaders: [{
            test: /\.jsx?$/,
            exclude: /node_modules/,
            loaders: ['babel']
        }]
    },
    resolve: {
        extensions: ['', '.js', '.jsx']
    },
    output: {
        path: __dirname + '/dist',
        publicPath: '/',
        filename: 'bundle.js'
    },
    devServer: {
        contentBase: './dist',
        hot: true
    }
};

you can use the repo i created as a boilerplate and upgrade the react-hot-loader version when it goes production. cheers.
