requestFrameModern

Optimal requestAnimationFrame & cancelAnimationFrame polyfill for modern development.

A polyfill based on request-frame

• Supports ES6, CJS & UMD
• Provides a clean polyfill for requestAnimationFrame & cancelAnimationFrame.
• Tested & working on: IE 9+, FF 25+, Opera 36+, Safari 6.1+, Chrome 30+, iOS 7+, Android 4.4+, Android Chrome 30+.
• Doesn't modify native functions unless specified.

If you need to support legacy browsers see requestFrame for full support from IE5.5+.

Install options

npm i request-frame-modern --save

yarn add request-frame-modern

import requestFrameModern from 'request-frame-modern';  // ES6

<script src="request-frame-modern.js"></script> // AMD, IIFE

const requestFrameModern = require('request-frame-modern');  // CJS

The API:

Assign the timing functions:

requestFrameModern( request | cancel | native ) request is default.

var request = requestFrameModern('request'); // window.requestAnimationFrame | setTimeout
var cancel = requestFrameModern('cancel'); // window.cancelAnimationFrame | cancelTimeout

Or re/ assign native functions:

requestFrameModern('native'); // re/ declares requestAnimationFrame & cancelAnimationFrame

Below is just an example of the requestAnimationFrame API, see links: MDN, MSDN & W3.

Loop something:

var requestId;

function something( useTimeStamp ){
    
    // Do something here
    
    requestId = requestFrameModern(something); 
}

requestId = requestFrameModern(something); // Assigns Id & calls "something"

Cancel something:

cancel(requestId);  // Cancels frame request 

The ideology

request-frame-modern aims to provide an optimal development consistency with the use of animation timing functions across the large number of browsers and devices. This lib is ideal for those who may want to avoid re-assigning native functions, or avoid interfering with other libs that do. requestFrameModern() is purposely not a constructor. The intention is for requestAnimationFrame to be used once or few times during execution since multiple task are expected to be more efficient via a single requestAnimationFrame loop compared to several instances.
