Offline First: Making Your App Awesome When the Network Isn't

" summary

Shows a working offline-capable Progressive Web App built with PouchDB and Apache CouchDB for local and remote storage, plus a Service Worker for caching, demonstrating continuous two-way sync across browsers so edits made offline appear in the cloud once restored. Demo uses Chrome and Firefox as separate clients, Cloudant-hosted CouchDB, timestamp IDs and revision handling, and a live sync option—results: immediate local writes, eventual consistency across devices, and fast cached page loads.
