webpack config for Electron project

webpack.config.js

'use strict';

const path = require('path');

let config = {
  context: path.resolve(__dirname, 'src'),
  target: 'electron',
  entry: './index',
  output: {
    path: path.resolve(__dirname, 'built'),
    filename: 'bundle.js',
    publicPath: '/built/'
  },
  resolve: {
    extensions: ['', '.js', '.jsx', '.css', '.png']
  },
  module: {
    loaders: [
      {
        test: /\.jsx?$/,
        loader: 'babel',
        query: {
          optional: ['runtime'],
          stage: 0
        },
        exclude: /node_modules/
      },
      {
        test: /\.css$/,
        loader: 'style!css'
      },
      {
        test: /.png$/,
        loader: 'file'
      }
    ]
  }
};

module.exports = config;

Looks like atom was replaced by electron as target value. See here: http://webpack.github.io/docs/configuration.html#target
