Typing indicator in Angular Chat UI component

21 Jan 20252 minutes to read

Show or hide typing indicator

You can use the typingUsers property to display the current user’s who are typing to indicate the active participants typing response within the chat conversations. If the property is empty the typing indicators will be removed.

The typing users are the UserModel[] collection, where you can update the user’s dynamically to display the current typing user.
