Connection Status

Real-time view of the SSE connection that powers automatic query invalidation. The indicator reflects the live state of the EventSource channel — connected, reconnecting, or disconnected.

What to watch for

  • ▶The green dot pulses while the SSE channel is open
  • ▶Add a todo — the event counter increments
  • ▶The todo list glows when an invalidation event is received
  • ▶Uptime resets if the connection is closed and re-opened

Generate an Invalidation Event

Adding a todo sends an SSE event — you will see the event counter increment above.
