Where do I put a Serviceworker file?
The path to your service worker file is not written correctly — it needs to be written relative to the origin, not your app’s root directory. In our example, the worker is at https://mdn.github.io/sw-test/sw.js , and the app’s root is https://mdn.github.io/sw-test/ . But the path needs to be written as /sw-test/sw.

What is cache busting Angular?

This entails attaching a unique version identifier to the file, which ensures that a fresh version is fetched, instead of a stale, cached version.
