This skill equips Claude with specialized knowledge for architecting and implementing high-performance real-time features. It provides production-ready patterns for WebSocket servers, Socket.io integration with Redis for horizontal scaling, and Server-Sent Events (SSE) for efficient unidirectional data streaming. Beyond basic implementation, the skill emphasizes reliability and security by including logic for exponential backoff reconnection, heartbeat mechanisms to detect stale connections, and strict authentication protocols during the initial handshake, making it ideal for building chat apps, live dashboards, and collaborative tools.
