Writing apps on the edge with CouchDB

on YouTube ↗30m

" summary

CouchDB stores JSON documents and serves them over HTTP so apps talk straight to the database CouchDB HTTP+JSON. The database runs JavaScript views with map/reduce views to extract and count data (demo shows 23 speakers) and replicates databases across servers, laptops and phones for multi‑master syncing replication across masters. Concrete apps include iio URL shortener, a Samy+coach JS wiki, and Mozilla’s raindrop which pipelines external fetchers (Python) into a huge view and 30MB of assets.
