How does it handle connection reliability?

The skill enforces the use of heartbeats (ping/pong), proper connection state handling, and automatic reconnection with exponential backoff.

Can I use this for migration from long polling?

Yes, it provides architectural guidance for migrating legacy polling systems to efficient, low-latency WebSocket bidirectional streams.

Is security built into the WebSocket implementation?

Yes, the skill prioritizes mandatory authentication before event handling, message scoping via rooms, and protection against common vulnerabilities.

Does this skill support Socket.IO and native WebSockets?

Yes, it provides specialized implementation patterns for Socket.IO, native ws, and uWebSockets, including protocol-specific best practices.

Can it help with horizontal scaling issues?

Absolutely. The skill includes workflows for scaling connections across clusters using Redis pub/sub adapters and sticky session configuration.
