collect-fps

Small module that uses requestAnimationFrame to collect what is the current FPS.

Usage

First install it:

npm install --save collect-fps

Calling it will initialize the collection and return a function. When invoked, that function will stop the collection and return the frame per seconds value (a float number).

import collectFPS from 'collect-fps'

const endCollection = collectFPS()

setTimeout(() => {
  const fps = endCollection()
  console.log(fps)
}, 1000)

If requestAnimationFrame is not available in your runtime, it will throw an error when invoked
