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.
