Does this skill support both Socket.io and the native ws library?

Yes, it provides implementation patterns and code snippets for both the feature-rich Socket.io framework and the lightweight, high-performance ws library.

Can I use this for production-scale applications?

Absolutely. The skill includes advanced sections on horizontal scaling using Redis adapters to ensure your WebSocket server can handle thousands of concurrent connections across multiple instances.

Does it include testing templates?

Yes, the skill includes a specialized unit test template using a client-server simulation to ensure your events, broadcasts, and room logic function correctly.

How does it handle WebSocket security?

It provides specific guidance and middleware examples for implementing JWT-based authentication for WebSocket connections, ensuring only authorized users can join specific namespaces or rooms.
