Can it help with horizontal scaling of connections?

Absolutely. It specializes in clustering WebSocket servers using Redis adapters and configuring load balancers for sticky sessions to maintain connection state.

Will it help me optimize for high-frequency updates?

Yes, it focuses on achieving low latency through heartbeat/ping-pong mechanisms, binary data compression, and efficient message throughput management.

How does it handle WebSocket security?

The skill enforces industry best practices such as JWT-based authentication during the handshake, CORS configuration, and implementing rate limits to prevent DoS attacks.

Does this skill support frameworks other than Socket.IO?

Yes, it provides implementation patterns for native WebSockets (ws), uWebSockets.js, and integration with backend frameworks like FastAPI and NestJS.
