Live WebSockets with SignalR

This terminal is connected to a live SignalR hub. It displays real-time events from your current session, including transport handshakes, presence updates, and keep-alive pings. Open another tab to see concurrent connection handling in action.

WHAT YOU'RE LOOKING AT

WEBSOCKET TRANSPORT

SignalR negotiates the best available transport and lands on WebSockets when the browser supports it. Long-polling is the fallback, not the default.

HUB PROTOCOL

Every line above maps to a real frame on the wire: handshake on connect, invocations for application events, periodic keep-alives, ordered close on disconnect.

AUTOMATIC RECONNECT

Disconnect your network briefly to observe the reconnection logic. The client retries automatically using exponential backoff, and the server synchronizes a fresh presence snapshot upon recovery.
