CouchDB, PouchDB and Offline-Tolerant Apps

on YouTube ↗51m

" summary

CouchDB is presented as a fault-tolerant JSON document store with an HTTP API, changes feed for replication, and MapReduce/Javascript views; Mango provides ad-hoc queries but needs indexes to avoid full scans. A browser-side PouchDB shopping list demo shows a local DB that does two-way sync with CouchDB, survives being offline, and reconciles simultaneous edits using deterministic conflict resolution (loser revisions remain queryable). The demo runs end-to-end (with expected live-demo delays) and recommends per-database access control and background syncing.
