Offline web applications don't exist anymore!
summary
Claim: modern Progressive Web Apps can make sites “never offline” by combining a service worker, a web manifest and client-side storage. Uses: cache strategies (cache‑first, network‑first, stale‑while‑revalidate), Workbox or PWA Builder, Angular PWA schematic, and background sync or Cloud Firestore offline persistence. Built demos: a custom offline HTML fallback and an Angular PWA that caches assets and lets users create/edit while offline; local changes automatically sync to the server and other clients when connectivity returns, proving the approach works.
