@angular/pwa

This is a schematic for adding Progress Web App support to an Angular app. Run the schematic with the Angular CLI:

ng add @angular/pwa

This makes a few changes to your project:

1. Adds @angular/service-worker as a dependency.
2. Enables service worker builds in the Angular CLI.
3. Imports and registers the service worker in the app module.
4. Adds a web app manifest.
5. Updates the index.html file to link to the manifest and set theme colors.
6. Adds required icons for the manifest.
7. Creates a config file ngsw-config.json, specifying caching behaviors and other settings.
