config.target = 'electron';

module.exports = config;

validate result:

[webpack-validator] Config is valid.
{ debug: true,
  devtool: 'cheap-module-eval-source-map',
  entry:
   [ 'webpack-hot-middleware/client?noInfo=true&reload=true',
     './src/app/app.js' ],
  target: 'electron' }

i found that:

const config = Object.create(baseConfig);
// console.log:   {} 

// ok
const config = new Object(baseConfig);

but still cannot run.
