Can it help with scaling real-time servers horizontally?

Absolutely. It provides detailed architectures for horizontal scaling using Redis pub/sub, sticky sessions, and proper Nginx proxy configurations.

Does this skill support Socket.IO?

Yes, it specializes in Socket.IO implementation along with native WebSockets (ws) and high-performance libraries like uWebSockets.js.

Does the skill include security best practices?

Yes, the skill enforces 'Must Do' constraints for connection authentication, event-level authorization, and protecting against sensitive data broadcasts.

Does it handle connection state management?

Yes, it provides robust patterns for handling reconnection logic, exponential backoff, heartbeats, and cleaning up dead connections.

Can it help me reduce message latency?

The skill includes specialized knowledge for optimizing throughput and achieving sub-10ms p99 latency in high-traffic real-time environments.
