micro-fps v0.1.2

micro-fps

A super lightweight fps meter, with near zero overhead

createFpsMeter is a function factory, it returns a new meter.
But why not a class? Last time I checked, accessing instance properties was slower than accessing variables on a near closure.

Usage

JS fiddle Example: https://jsfiddle.net/Victornpb/g8pra2a6/

import microFps from 'micro-fps';

const REFRESH_RATE = 2; //update twice a second

const fpsTick = createFpsMeter(info=>{
    fps_div.innerHTML = info.fps.toFixed(2);
    console.log(info);
}, REFRESH_RATE);

Then call the returned function on every frame of your loop

//game loop
setInterval(function loop(){
    fpsTick();
    
    //do stuff

}, 1000/60);

Builds

If you don't use a package manager, you can access micro-fps via unpkg (CDN), download the source, or point your package manager to the url.

micro-fps is compiled as a collection of CommonJS modules & ES2015 modules(http://www.2ality.com/2014/0 -9/es6-modules-final.html) for bundlers that support the jsnext:main or module field in package.json (Rollup, Webpack 2)

The micro-fps package includes precompiled production and development UMD builds in the dist/umd folder. They can be used directly without a bundler and are thus compatible with many popular JavaScript module loaders and environments. You can drop a UMD build as a <script> tag on your page. The UMD builds make micro-fps available as a window.microFps global variable.
