AngularJS and Webpack Integration

I am looking for some help with using webpack for a large AngularJS application. We are using folder structure based on feature (each feature/page has a module and they have controllers, directives). I have successfully configured webpack to get it working with Grunt, which produces one single bundle. I want to create chunks as its going to be a large app, we would like to load modules (page/feature) artifacts asynchronously.
