socket.io-adapter-postgres

PostgreSQL-based adapter for Socket.IO enabling horizontal scaling by broadcasting and emitting events across multiple Socket.IO instances. Version 1.2.1 is the latest stable release, with infrequent updates (no recent commits). Unlike Redis-based adapters, it uses PostgreSQL's LISTEN/NOTIFY for pub/sub, making it suitable for teams already running PostgreSQL. Supports remote join, leave, and disconnect across nodes.
