Offline web applications don't exist anymore!
summary
Claim: modern PWAs with service workers plus Cloud Firestore make offline-first experiences practical. Shows caching strategies (cache‑first, network‑first, stale‑while‑revalidate), tools (PWABuilder, Workbox, Angular CLI's ng add @angular/pwa) and an Angular demo using Cloud Firestore with enablePersistence so edits made offline queue locally (40 MB default cache, ~500 offline transactions) and sync on reconnect with last‑write‑wins semantics. Demonstration includes three clients and a phone showing edits persisted offline and propagated automatically when back online.
