Events

Subscribe to lifecycle, connection, conversation, and message events with on().

Subscribe with on(), which returns an unsubscribe function. Every event uses the same envelope.

const off = chat.on("message:received", (event) => {
  console.log(event.payload.conversation.id, event.payload.message.id);
});
 
off(); // stop listening

interface ChatEvent<TPayload> {
  id: string;
  type: ChatEventName;
  createdAt: string;   // ISO‑8601
  payload: TPayload;
}
