Recommended way to track client connection (detect browser close/redirection, etc)


I am trying to establish some kind of an active session when the user visits a particular page and I want to detect when this session closes (either by closing browser, or user moves to some other page, etc). This is because I want to do some clean up on the server when that session closes.

I found a good solution for the Hearbeat method on StackOverflow. However, I’ve got 2 concerns:

  1. That answer is quite old and I’m curious if there are better ways to do this now
  2. Hundreds of users pinging the server every 5 second does not sound too efficient.

On that same question, someone suggested using _session object like so:
this._session.socket.on("close", function() { /*do your thing*/});

But that’s not documented and I’m not sure how reliable that would be.

There is a package that I explored for this:
This works well but it does not track the session on a per page basis and does not fit my requirement.

So I am currently thinking of going with the Heartbeat method of pinging the server every few seconds but wanted to get other opinions on this.



Try, I think it will fit your use case very well.


The package seems to come at a good time :slight_smile: It does look good. I am still going through the docs but is there a way to send an extra piece of data from the client?

Basically, if there is any way I can identify in the server ‘onSessionDisconnected’ callback what this session was about (Iron router name of the route user was at OR some other custom data that I have on the client to identify the session)?
