Angular 7 Service worker feature

Angular’s service worker is designed to load application in the offline mode. Similar to the native mobile app.

Using angular service worker, we could cache the application as one unit as a resource.

Few benefits of the feature:

1. It improves the end-user experience over a slow or fluctuating network connection.
2. It saves bandwidth when possible.
3. We can avoid round-trip delays when loading the application.
