frameRate V4 JS

Determines the number of frames per second (fps) an animation is played at.
This value can be modified later with animation.fps = 30.

Accepts

A Number greater than 0

The frame rate is capped to the monitor refresh rate or in some cases by the browser itself.

Default

120

To change the default value globally, update the engine.defaults object.

import { engine } from 'animejs';
engine.defaults.frameRate = 30;

frameRate code example

import { animate } from 'animejs';

const [ $range ] = utils.$('.range');
const [ $fps ] = utils.$('.fps');

const animation = animate('.circle', {
  x: '16rem',
  loop: true,
  alternate: true,
  frameRate: 60,
});

const updateFps = () => {
  const { value } = $range;
  $fps.innerHTML = value;
  animation.fps = value;
}

$range.addEventListener('input', updateFps);

<div class="large row">
