The big idea
WebSockets keep a connection open between browser and server, so messages fly both ways instantly. AI walks you through socket.io or native WebSocket code, and explains the gotchas like reconnecting and auth.
Some examples
- Ask AI: 'Show me a minimal socket.io chat with rooms.'
- AI explains the difference between WebSockets and Server-Sent Events.
- AI writes a reconnect-with-backoff helper.
- AI debugs why your socket disconnects after 60 seconds.
Try it!
Build a tiny two-tab chat: messages typed in one tab appear in the other. Ask AI to scaffold both client and server.
