Memory usage issue in music streaming application

Other Questions Spotify
1

I’m working on an app that uses a popular music streaming service’s API. I’ve noticed the app’s memory usage keeps growing without limit over time. I narrowed it down to this bit of code:

let musicController = audioSystem.controller;
let memoryProblemTimer = setInterval(checkPlayback, 500);

function checkPlayback() {
    musicController.isPlaying = true;
}

Every time this function runs, it seems to increase the app’s memory usage. I let it run until it hit 1.5GB and it was still going up. Is this a problem with my code or could it be an API issue?

I’m using the latest version of the API on macOS Monterey. Any ideas on how to fix this or what might be causing it? Thanks for any help!

hey man, i think ur problem is with that setinterval thing. it keeps making new stuff without cleaning up. try something like this:

let isPlaying = false;
function checkPlayback() {
  if (musicController.isPlaying !== isPlaying) {
    isPlaying = musicController.isPlaying;
    // do stuff here
  }
}

this should help with memory. good luck!

I’ve encountered similar memory issues in my projects. The problem likely stems from the setInterval function continuously creating new function instances without proper cleanup. To address this, you could refactor your code to use a single instance of the checkPlayback function:

let musicController = audioSystem.controller;
let isPlaying = false;

function checkPlayback() {
    if (musicController.isPlaying !== isPlaying) {
        isPlaying = musicController.isPlaying;
        // Perform any necessary actions based on playback state
    }
}

let memoryProblemTimer = setInterval(checkPlayback, 500);

This approach should significantly reduce memory usage. Remember to clear the interval when it’s no longer needed:

clearInterval(memoryProblemTimer);

If the issue persists, consider using Chrome DevTools or similar debugging tools to profile your application’s memory usage and identify any remaining leaks.

As someone who’s worked extensively with music streaming APIs, I can shed some light on your issue. The problem isn’t with the API, but rather with your code structure. The setInterval function is creating a new closure every 500ms, which is likely causing a memory leak.

Instead of constantly reassigning the isPlaying property, try this approach:

let musicController = audioSystem.controller;
musicController.isPlaying = true;

function checkPlayback() {
    if (!musicController.isPlaying) {
        clearInterval(memoryProblemTimer);
    }
}

let memoryProblemTimer = setInterval(checkPlayback, 500);

This way, you’re not creating new closures repeatedly. Also, make sure to clear the interval when it’s no longer needed. This should significantly reduce memory usage. If you’re still seeing issues, consider using requestAnimationFrame for more efficient polling. Hope this helps!
