WebSocket Connection Management

Production-grade WebSocket connection manager with health verification and capacity management.

When to Use This Skill

• Building real-time features with WebSockets
• Need connection limits (global and per-room)
• Want to detect and clean up stale connections
• Require reliable user-to-connection mapping

Core Concepts

WebSocket connections can appear connected but be stale (client crashed, network dropped). The solution:

• Track connections by lobby/room AND by user ID
• Enforce connection limits (global + per-lobby)
• Ping/pong health verification
• Automatic stale connection cleanup
