Real-time Sync (WebSockets)

This skill enables applications to push updates to users instantly without page refreshes.

Instructions

1. Choose between WebSockets (bidirectional) or Server-Sent Events (unidirectional).
2. Set up event emitters for key actions (e.g., new message, stock price update).
3. Manage connection lifecycles (connect, disconnect, heartbeats).
4. Implement room-based or channel-based broadcasting.
5. Ensure scalability for high-concurrency environments.

Examples

• "Add real-time chat functionality to my app using Socket.io."
• "Push live flight status updates to users via WebSockets."
