PWAs, are we there yet?!
summary
Progressive Web Apps reach practical maturity: service workers plus a web manifest over HTTPS give offline, installable apps; Angular CLI adds a PWA with one command and generates an ngsw-config.json that encodes cache strategies. Demonstrated push uses web-push and Firebase endpoints and a VAPID key pair, and Lighthouse moves from 82 to 100 after small fixes. Browser limits matter: Chrome allows <~6% free storage, Safari evicts caches >50MB and may unregister service workers after weeks. App‑install UI and APIs remain inconsistent across browsers.
