Transient Messages

Learn how to send transient messages

Transient messages are messages that are sent in real-time only and are not saved or tracked anywhere. The receiver of the message will only receive the message if he is online and these messages cannot be retrieved later.

Send a Transient Message

You can use the sendTransientMessage() method to send a transient message to a user or in a group. The receiver will receive this information in the onTransientMessageReceived() method of the MessageListener class. In order to send the transient message, you need to use the TransientMessage class.

let receiverId = "UID";
let receiverType = CometChat.RECEIVER_TYPE.USER;
let data = { "LIVE_REACTION": "heart" };

let transientMessage = new CometChat.TransientMessage(receiverId, receiverType, data);
CometChat.sendTransientMessage(transientMessage);
let receiverId = "GUID";
let receiverType = CometChat.RECEIVER_TYPE.GROUP;
let data = { "LIVE_REACTION": "heart" };

let transientMessage = new CometChat.TransientMessage(receiverId, receiverType, data);
CometChat.sendTransientMessage(transientMessage);

Real-time Transient Messages

In other words, as a recipient, how do I know when someone sends a transient message?

You will receive the transient message in the onTransientMessageReceived() method of the registered MessageListener class.

let listenerId = "UNIQUE_LITENER_ID";

CometChat.addMessageListener(
  listenerId,
  new CometChat.MessageListener({
    onTransientMessageReceived: transientMessage => {
      console.log('transient message received', transientMessage);
    },
  })
);
