What methods can be utilized to accurately determine a user's online status without continuously sending AJAX requests to the server through setInterval?

Seeking effective methods to determine a user's online status

I am currently employing an inefficient technique to address this issue: I continuously send AJAX requests to the server at set intervals using setInterval, allowing the server to gauge the user's online presence based on the request timestamp.

Although I acknowledge that this method is suboptimal and results in unnecessary consumption of Internet bandwidth and places strain on the server, it remains the simplest way to achieve the desired functionality.

With that said, I am open to suggestions or alternative approaches from those with better ideas.

Answer №1

I encountered the same issue myself.

There are 2 potential solutions (choose one):

••1•• Try using jQuery IDLE: https://github.com/kidh0/jquery.idle

••2•• Implement a document.addEventListener()

Example:

document.addEventListener("visibilitychange", function() { 
    wistatus = document.visibilityState; 
    if ( wistatus == "visible" ) { /* Insert AJAX functionality here */ }  
    else { /* Insert AJAX functionality here */ }
});
