I think this will not work anymore

[dnotes]

With recent changes to SvelteKit, the service worker build process no longer gets modified by Vite plugins or configuration (see here for example) so I don't think this package will work anymore. Instead you can do something like the following in src/service-worker.js:

import { build, files, prerendered, version } from '$service-worker'
import { precacheAndRoute, type PrecacheEntry } from 'workbox-precaching'

let cacheEntries:PrecacheEntry[] = [
  ...build,
  ...files,
  ...prerendered,
].map(url => ({ url, revision: version }))
precacheAndRoute(cacheEntries)

// ...etc.

Also until sveltejs/kit#6329 lands you'll have to manually replace all of the Workbox-generated process.env.NODE_ENV calls in the service worker file after it is built.

It was good while it lasted. Thanks. :)
