Leave A Group

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 messages and updates from it. Once you leave, you’ll need to rejoin to participate again.

Group owners cannot leave without first transferring ownership to another member. See Transfer Group Ownership.

Use leaveGroup() to leave a group.

TypeScript
JavaScript

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);
  }
);

const GUID = "GUID";

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

Parameter	Description
`GUID`	The GUID 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 true (boolean).

Real-time Group Member Left Events

TypeScript
JavaScript

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 });
      }
  })
);

CometChat.addGroupListener(
  "UNIQUE_LISTENER_ID",
  new CometChat.GroupListener({
      onGroupMemberLeft: (message, leavingUser, 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");
