Realtime Notifications

AddChat Codeigniter Pro comes with a custom Internal notification system & Pusher integration for chatting in realtime.

Realtime notifications

Internal notification is a custom real-time notification system built using VueJs, which does not require any additional server setup. It works smoothly behind the scenes.


Internal notification system sends regular Asynchronous HTTP/S Requests to the server for getting the latest messages on the fly. For the geeks who wanna know more, it only runs a single SELECT database query in a single Table to fetch the latest messages.

{info} The total no. of records fetched from single SELECT query are equal to the total no. of users chatting simultaneously.

{primary} Admin can switch between Pusher & Internal notification system with just one click.

Internal Notifications

Internal notification system fetches the following things in realtime (without page refresh)

  1. Latest received messages from multiple users
  2. Latest messages while user-to-user chatting
