Offline first applications, syncing with PouchDB & CouchDB
summary
Shows how to make a web or hybrid app write to PouchDB local DB and rely on CouchDB replication over HTTP to sync changes, with a live demo of an AngularJS image‑sharing PWA packaged as Electron and a Chrome app that keeps offline likes and uploads then reconciles when online. Uses pouchdb-server for the demo and the CouchDB replication protocol; notes CouchDB's default winning‑rev conflict strategy is insufficient so implement custom merge logic, and warns live PouchDB polling can waste battery and bandwidth.
