javascript - How do I display the followers count in real time using firebase?

Question

I have an application where users can follow other users. I want to have a real-time update system, display the total count of followers a user has.

I've just started playing around with Firebase and Pusher, but I don't understand one thing - will each user have their own 'channel'? How would I handle such thing as a follower counter update?

I followed the tutorial and saw that push method can create lists, so one solution I can see is having a list of all the users, each user being an object something like this:

{ username: 'john_doe', follower_count: 6 }

But I don't understand how would I actually track it on the front end? Should I have a filter, something like this?

var user = users.filter(function(user) { return user.username === 'john_doe'; });
// code to display user.follower_count

Or is there a different way that I'm missing?
