Previously, the ServiceWorker registration options should be defined as
an object literal (in order for them to be compatible with Ahead-of-Time
compilation), thus making it impossible to base the ServiceWorker
behavior on runtime conditions.
This commit allows specifying the registration options using a regular
provider, which means that it can take advantage of the `useFactory`
option to determine the config at runtime, while still remaining
compatible with AoT compilation.
PR Close#21842
This service worker is a conceptual derivative of the existing @angular/service-worker maintained at github.com/angular/mobile-toolkit, but has been rewritten to support use across a much wider variety of applications.
Entrypoints include:
@angular/service-worker: a library for use within Angular client apps to communicate with the service worker.
@angular/service-worker/gen: a library for generating ngsw.json files from glob-based SW config files.
@angular/service-worker/ngsw-worker.js: the bundled service worker script itself.
@angular/service-worker/ngsw-cli.js: a CLI tool for generating ngsw.json files from glob-based SW config files.
