-This disables access to DOM typings like `HTMLElement` which are not available inside a service worker and instantiates the correct globals. The reassignment of `self` to `sw` allows you to type cast it in the process (there are a couple of ways to do this, but the easiest that requires no additional files). Use `sw` instead of `self` in the rest of the file. The reference to the SvelteKit types ensures that the `$service-worker` import has proper type definitions. If you import `$env/static/public` you either have to `// @ts-ignore` the import or add `/// <reference types="../.svelte-kit/ambient.d.ts" />` to the reference types.
