Get Started With Pusher: Using Presence Channels
Aug 23, 2018 @ 10:53:56

The TutsPlus.com site has continued their series looking at using the Pusher real-time communication service in your PHP application with a new tutorial. In this latest article, they show the use of presence channels, a feature that makes it simpler to know which users are connected to which channels.

In this series, we've been learning about Channels from Pusher, a platform that allows you to give your users the seamless real-time experience they want.

Presence channels build on the security provided by private channels, but they add the benefit of knowing which users are subscribed and connected to that channel. The best part is how easy it is to implement and use presence channels, and it's even easier if you've already configured your app to use private channels.

As in the previous articles in the series, they've provided both a screencast of the tutorial and the text-based version. They show how to modify the server you've already created to authorize a user and send that information along with the messages back to the Pusher service. They also include the changes to the frontend client to gather and send user information.
