Ways to assess the efficiency of the client browser using JavaScript

As I work on creating my website, I have come across an issue with lag when scrolling through a certain viewport that contains a canvas element. To address this problem, I am looking to analyze the browser's performance, specifically focusing on the frames per second (FPS). My goal is to develop a JavaScript function that will conditionally display the canvas only if the FPS is above 50.

For additional context, I am utilizing p5.js and have made efforts to optimize the code for better performance. Additionally, I am working within Vue.js framework.

That sums up the key details of my situation. Can anyone provide guidance on how to effectively evaluate browser performance in this scenario?

Answer №1

If you're working with p5.js, it seems like you are in need of the frameRate() function.

For more details, check out the documentation, but to give you a quick idea, you might want to try something along these lines:

function draw(){
  background(255);
  text(frameRate(), width/2, height/2);
}
