WebSockets are the standard for real-time bidirectional communication -- streaming LLM output to browsers, live agent status updates, and collaborative agent interfaces all depend on WebSocket primitives. Socket.IO adds rooms, namespaces, and automatic reconnection on top of the standard protocol. Confidence is docs-derived.
The WebSocket API is simple: upgrade an HTTP connection, then exchange text/binary frames. Socket.IO adds event-based messaging, rooms for broadcast groups, namespaces for logical separation, and acknowledgements for reliable delivery. Both browser and server SDKs are mature.
Auth for WebSocket connections is implemented at the HTTP upgrade handshake: token or cookie auth in the initial request headers. Socket.IO middleware enables server-side auth before accepting connections.
Operationally, WebSocket connections are long-lived -- load balancers must support sticky sessions or WebSocket-aware routing. Horizontal scaling requires a pub/sub adapter (Redis, etc.) for Socket.IO room broadcasting across multiple server instances.
Documentation for the WebSocket API (MDN) and Socket.IO (socket.io/docs) is excellent. Both have been stable for years with extensive community resources. Developer experience is straightforward; the patterns are well-understood across the industry.
