requestAnimationFrame & cancelAnimationFrame polyfill for optimal cross-browser development.
npm install request-frame!img
- Supports ES6 - AMD - CJS & IIFE
- Provides a clean polyfill for requestAnimationFrame & cancelAnimationFrame.
- Tested & working on: IE 5.5+, FF 3+, Opera 11.16+, Safari 4+, Chrome 14+, iOS 3+, Android 2.3+, Android Chrome 28+.
- iOS 6 bug fix without user-agent sniffing.
- Firefox 4 - 10 function mismatch normalization.
- Doesn't modify native functions unless specified.
- AMD compliant.
#### Install options
npm i request-frame --save | bower i request-frame | src | release
``javascript`
import requestFrame from 'request-frame'; // ES6
`javascript`
// AMD, IIFE
`javascript`
const requestFrame = require('request-frame'); // CJS
javascript
var request = requestFrame('request'); // window.requestAnimationFrame | setTimeout
var cancel = requestFrame('cancel'); // window.cancelAnimationFrame | cancelTimeout
`
#### Or re/ assign native functions:
`javascript
requestFrame('native'); // re/ declares requestAnimationFrame & cancelAnimationFrame
`
Below is just an example of the requestAnimationFrame API, see links: MDN, MSDN & W3. #### Loop something:
`javascript
var requestId;function something( useTimeStamp ){
// Do something here
requestId = request(something);
}
requestId = request(something); // Assigns Id & calls "something"
`#### Cancel something:
`javascript
cancel(requestId); // Cancels frame request
`$3
request-frame 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. requestFrame() 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.$3
Supports everything from IE5+
$3
Just do it!#### Test
npm run test` - ./test/
- ./test/compatibility-assignation-amd.html
- ./test/compatibility-assignation.html
- ./test/compatibility-native-amd.html
- ./test/compatibility-native.html
