iMock Socket

iMock Socket is a WebSocket cluster server and client library that combines Socket.IO with Redis for horizontal scaling. The current stable version is 0.0.28, released with a moderate cadence. It differentiates by offering a lightweight abstraction over Socket.IO with built-in Redis pub/sub for multi-server setups, making it suitable for real-time applications that need to scale across multiple nodes. It supports both server and client roles, integrates easily with Express, and is designed for Node.js 8.8+.
