livedb

Database wrapper for realtime applications, providing the backend for ShareJS, Racer, and Derby. This package (v0.5.13 at current release) exposes an API for submitting operations (via OT), subscribing to document changes, and making live queries. It requires a separate database backend (e.g., livedb-mongo for MongoDB) and an optional driver for multi-server setups. Key differentiators: built for Operational Transformation, stores all operations forever, and supports live query result feeds. Note: the v5 releases listed are for the related share/sharedb package, not livedb itself; livedb appears to be in maintenance mode with no recent updates.
