In year 2018:

Install following packages if you haven't yet:

npm install babel-loader babel-preset-react

webpack.config.js

{
    test: /\.jsx?$/,
    exclude: /node_modules/,
    use: [
      {
        loader: 'babel-loader',
        options: {
          presets: ['es2015','react']  // <--- !`react` must be part of presets!
        }
      }
    ],
  }
