How can I get the URL of a file inside a service worker?

❔ Question

How can I get the URL of a file inside my service worker? I probably want something like url_for('./index.js').

Edit: I decided to use https://github.com/mugi-uno/parcel-plugin-bundle-manifest and it's working well so far. It'd be nice if someone could confirm that there isn't a much better approach.

🔦 Context

I'm trying to add offline support to my app.

💻 Code Sample

// service-worker.js

const CACHED = [
  '.',
  // These two don't work thanks to name mangling (and scss → css).
  './index.scss',
  './index.js'
];

#2306 would be a generic solution so long as the set of assets you want to reference is known statically. I don't think there's a way to do this sort of thing today that doesn't involve a plugin.

There is currently no better way to achieve this. (Could personally see this being added using require.resolve(...) returning the output path)
