  devtool: 'inline-source-map',
  devServer: {
    contentBase: './dist'
  }
});

const merge = require('webpack-merge');
const common = require('./webpack.common.js');

module.exports = merge(common(), {
  devtool: 'inline-source-map',
  devServer: {
    contentBase: './dist'
  }
});

Notice the only change is running common() instead of common.
