Event object

An object that refers to a single piece of information emitted when someone is typing, receiving a message, mentioning others in a message, or reporting a message to the admin.

Contrary to other Chat SDK entities, this object provides no methods. Its only purpose is to pass payloads of different types emitted when certain chat operations occur.

The Event object has the following properties:

class Event<T extends EventType> {
timetoken: string
type: T
payload: EventPayloads[T]
channelId: string
userId: string
}

Use case

You can use events to collect historical chat events or create your own custom events. You can later visualize them in a graphical form (like a moderation dashboard for flagged messages) or create additional business logic with functions that these events can trigger.
