webpack version:
4.x

sw-precache-webpack-plugin version:
0.11.4

Please tell us about your environment:
OSX 10.13.4

Browser:
Chrome 66

Current behavior:

In webpack 4, I can use an external global var to set the path for my app js and chunks by setting __webpack_public_path__.

SW Precache doesn't or can't use this as far as I can tell.

So I have a question - given that by default the service worker will be in the shared output directory, why not use the service worker registration scope to set the cached URLs? For example:

self.registration.scope + 'path/to/file.js'
