memory-stats.js
Like stats.js but for JS memory
@jeromeetienne, inspired by mrdoob's stats.js code, wrote this as part of tquery. I've now promoted it to a standalone repo and cleaned it all up.
Usage:
- Start Chrome with
--enable-precise-memory-info
- Otherwise the results from performance.memory are bucketed and less useful.
- Include memory.stats.js
- Instantiate it (
stats = new MemoryStats()
, add thestats.element
to the DOM, and runstats.update()
regularly.
That might look something like:
var stats = new MemoryStats();
stats.domElement.style.position = 'fixed';
stats.domElement.style.right = '0px';
stats.domElement.style.bottom = '0px';
document.body.appendChild( stats.domElement );
requestAnimationFrame(function rAFloop(){
stats.update();
requestAnimationFrame(rAFloop);
});
Run Chrome with the flag and open demo/index.html
to see it in action.
