Let's say you develop an application and want a real-time connection which is subscribed to one channel. Let's also assume that this channel is used for user personal notifications. So only one user in the application can subcribe to that channel to receive its notifications in real-time.

In this post we will look at various ways to achieve this with Centrifugo, and consider trade-offs of the available approaches. The main goal of this tutorial is to help Centrifugo newcomers be aware of all the ways to control channel permissions by reading just one document.

And... well, there are actually 8 ways I found, not 101 😇

In this tutorial, we will create a basic chat server using the Django framework and Centrifugo. Our chat application will have two pages:

  1. A page that lets you type the name of a chat room to join.
  2. A room view that lets you see messages posted in a chat room you joined.

The room view will use a WebSocket to communicate with the Django server (with help from Centrifugo) and listen for any messages that are published to the room channel.

Centrifugo is a scalable real-time messaging server in a language-agnostic way. In this tutorial we will integrate Centrifugo with NodeJS backend using a connect proxy feature of Centrifugo for user authentication and native session middleware of ExpressJS framework.

Why would NodeJS developers want to integrate a project with Centrifugo? This is a good question especially since there are lots of various tools for real-time messaging available in NodeJS ecosystem.
