How to get all currently connected users #7

Closed Yamaha32088 closed 6 years ago

Yamaha32088 commented 6 years ago

This is more of a question than an issue. What I am looking to do is get the names of all currently connected clients. I have the code below:

var chanId  = arguments.websocket.getPathParameters().channel;
var connMgr = arguments.websocket.getConnectionManager();

var currentSubscribers = ArrayMap(connMgr.getChannel(chanId).getSubscribers().toArray(), function(subscriber) {
    return arguments.subscriber.getSessionScope().user.label;
});

This seems to do what I want because inside the sessionScope is a user struct that contains the name of the user. Is there a better way to accomplish the same thing?

Another thing I was wondering about is that if I put the above code in the (onClose, onUnsubscribe) functions and I have two users connected to a channel and I navigate one user away it will still show the user that navigated away in the array returned. Maybe I am doing something wrong. Thanks in advance for any help and creating such a great extension!
