Up and Running with Progressive Web Apps
summary
A live SodaPops demo shows a real web app retrofitted with a service worker that caches a named cache static and serves an offline HTML fallback so the app still works in “Homer Illinois” no‑signal situations. A web app manifest makes the site installable to home screen with a splash screen; Lighthouse reports an 82 PWA score but flags a missing cached start_url. Push uses VAPID keys and the web-push library to encrypt payloads and deliver notifications with action buttons that update the server and app state.
