Realtime and WebSockets

Purpose

Build realtime features that behave correctly when the connection drops — which it will, constantly, on mobile networks. The hard part is not the socket; it is the state after the reconnect.

When to Use

• Building live updates, chat, presence, collaborative editing, or streaming dashboards.
• Choosing between WebSockets, SSE, and polling.
• Scaling a socket server beyond one instance.
• Diagnosing memory growth or dropped messages under load.
