OfflineFirst Apps with PouchDB and CouchDB
summary
Demo shows a local PouchDB-powered shopping list that syncs to CouchDB/Cloudant and keeps browsers consistent after offline edits, proving replication actually works live. Service workers cache assets; a live sync with retry and a changes feed pushes updates when network returns. Conflict resolution preserves losing revisions for manual merge; views and Mango queries run server-side for performance. Code lives on GitHub and the demo behaves predictably in tests.
