JavaScript Performance Monitor

stats.js

About

This is a fork of Mr. Doob's stats.js, found here, for use in my own personal Three.js projects.

Changes from original

• Updated to TypeScript to use ES6 class syntax, replacing the function constructor pattern.

JavaScript Performance Monitor

This class provides a simple info box that will help you monitor your code performance.

• FPS Frames rendered in the last second. The higher the number the better.
• MS Milliseconds needed to render a frame. The lower the number the better.
• MB MBytes of allocated memory. (Run Chrome with --enable-precise-memory-info)
• CUSTOM User-defined panel support.

Installation

npm install fork_stats.js

Usage

const stats = new Stats();
stats.showPanel(1); // 0: fps, 1: ms, 2: mb, 3+: custom
document.body.appendChild(stats.dom);

function animate() {
  stats.begin();

  // monitored code goes here

  stats.end();

  requestAnimationFrame(animate);
}

requestAnimationFrame(animate);
