Webpack 4.0.0 Error

I am trying to use Webpack v4.0.0 and get the following:

ERROR in ./src/Main.elm

webpack.config.js

module.exports = {
	module: {

				use: {
					loader: 'elm-webpack-loader'
				}
			}
		],
		noParse: [/\.elm$/]
	}
};

src/index.js

const Elm = require('./Main.elm');
// import Elm from './Main.elm'
console.log('App started...');

src/Main.elm
