node-redis-room

A library for using Socket.IO rooms and namespaces across multiple Node.js processes via Redis. Version 0.1.1 (unmaintained). It provides a Redis-backed pub/sub mechanism to synchronize room membership, broadcasts, and user tracking in clustered Socket.IO deployments. Key differentiators: simple API for joining/leaving rooms, broadcasting, and querying room members across nodes. However, it is outdated and relies on Socket.IO v0.9.x, incompatible with modern Socket.IO versions.
