request-animation-frame-shim
This shim doesn't implement any fallback for old browsers. Polyfilling features
are limited to support prefixes (module exports requestAnimationFrame
,
webkitRequestAnimationFrame
or mozRequestAnimationFrame
, depending which one
is available). The key concept of using this shim is to use those functions
not directly from global context and be able to mock them during testing
(see request-animation-frame-mock).
You can use it with ES6 transpilers like Babel.
import { requestAnimationFrame, cancelAnimationFrame } from 'request-animation-frame-shim';
let frameRequest = requestAnimationFrame(function frameHandler(time) {
// do your animation step or whatever you want to
frameRequest = requestAnimationFrame(frameHandler);
});
cancelAnimationFrame(frameRequest);
As well as with standard JavaScript.
var requestAnimationFrame = require('request-animation-frame-shim').requestAnimationFrame;
var cancelAnimationFrame = require('request-animation-frame-shim').cancelAnimationFrame;
var frameRequest = requestAnimationFrame(function frameHandler(time) {
// do your animation step or whatever you want to
frameRequest = requestAnimationFrame(frameHandler);
});
cancelAnimationFrame(frameRequest);
