Customization of Service Worker

Created by: raymondsze

Apart from offline support, service worker could be used for handling notification. Seems in 1.0.0, there is no way to do this kind of customization.

sw-precache-webpack-plugin provide the 'importScripts' option to do that purpose. offline-plugin also provide an option 'entry' for this purpose.
