Leave A Group

Learn how to leave a group and receive real-time events when members leave using the CometChat JavaScript SDK.

AI Integration Quick Reference

// Leave a group
await CometChat.leaveGroup("GUID");

// Listen for member left events
CometChat.addGroupListener("listener", new CometChat.GroupListener({
  onGroupMemberLeft: (message, leavingUser, group) => { }
}));

Leave a group to stop receiving updates and messages from that conversation.

Leave a Group

Use leaveGroup() to leave a group.

Leave Group

const GUID = "GUID";

CometChat.leaveGroup(GUID).then(
hasLeft => {
  console.log("Group left successfully:", hasLeft);
}, error => {
  console.log("Group leaving failed with exception:", error);
}
);

TypeScript

const GUID: string = "GUID";

CometChat.leaveGroup(GUID).then(
  (hasLeft: boolean) => {
      console.log("Group left successfully:", hasLeft);
  }, (error: CometChat.CometChatException) => {
      console.log("Group leaving failed with exception:", error);
  }
);

Parameter	Description
GUID	The UID of the group you would like to leave

Once a group is left, the user will no longer receive any updates or messages pertaining to the group.

On success, the method resolves with a success message string confirming the operation.

Real-time Group Member Left Events

Register a GroupListener to receive events when members leave.

Group Listener

CometChat.addGroupListener(
  "UNIQUE_LISTENER_ID",
  new CometChat.GroupListener({
      onGroupMemberLeft: (message, leavingUser, group) => {
          console.log("User left", { message, leavingUser, group });
      }
  })
);

TypeScript

CometChat.addGroupListener(
  "UNIQUE_LISTENER_ID",
  new CometChat.GroupListener({
      onGroupMemberLeft: (message: CometChat.Action, leavingUser: CometChat.User, group: CometChat.Group) => {
          console.log("User left", { message, leavingUser, group });
      }
  })
);

Always remove group listeners when they’re no longer needed (e.g., on component unmount or page navigation). Failing to remove listeners can cause memory leaks and duplicate event handling.

CometChat.removeGroupListener("UNIQUE_LISTENER_ID");

Missed Group Member Left Events

When fetching message history, leave events appear as Action messages with:

• action — "left"
• actionBy — User who left
• actionFor — Group that was left
