    This method is semi-realtime. This means that this data will be eventually correct, but will also be possibly incorrect for a few seconds. The Conversations system does not provide real time events for counter values changes.

    This is useful for any UI badges, but it is not recommended to build any core application logic based on these counters being accurate in real time.

getParticipantsCount

  • getParticipantsCount(): Promise<number>

    This method is semi-realtime. This means that this data will be eventually correct, but will also be possibly incorrect for a few seconds. The Conversations system does not provide real time events for counter values changes.

    This is useful for any UI badges, but it is not recommended to build any core application logic based on these counters being accurate in real time.

    Returns Promise<number>

getUnreadMessagesCount

  • Get count of unread messages for the user if they are a participant of this conversation. Rejects if the user is not a participant of the conversation.

    Use this method to obtain the number of unread messages together with Conversation.updateLastReadMessageIndex instead of relying on the message indices which may have gaps. See Message.index for details.

    This method is semi-realtime. This means that this data will be eventually correct, but it will also be possibly incorrect for a few seconds. The Conversations system does not provide real time events for counter values changes.

    This is useful for any UI badges, but it is not recommended to build any core application logic based on these counters being accurate in real time.

    If the read horizon is not set, this function will return null. This could mean that all messages in the conversation are unread, or that the read horizon system is not being used. How to interpret this null value is up to the customer application.
