+# raf
+
+[![Browser Support](http://ci.testling.com/chrisdickinson/raf.png)](http://ci.testling.com/chrisdickinson/raf)
+
+requestAnimationFrame polyfill for node and the browser.
+
+```js
+var raf = require('raf')
+
+raf(function tick() {
+  // Animation logic
+  raf(tick)
+})
+```
+
+**Note:** The stream/event emitter logic found in versions prior to 1.0.0 can be found in [raf-stream](https://www.npmjs.org/package/raf-stream).
+
+## Getting started
+
+### CommonJS (Node, Browserify, Webpack, etc.)
+
+Install `raf` from npm:
+
+```bash
+npm install --save raf
+```
+
+Require it like you would any other module:
+
+```js
+const raf = require('raf')
+```
+
+### AMD (require.js, etc)
+
+Download the UMD-bundle from [wzrd.in](https://wzrd.in/standalone/raf@latest) (remember to include the current version number in the filename).
+
+Add it to your AMD module loader config and require it like you would any other module:
+
+```html
+define(['raf'], raf => {...})
+```
+
+### `<script>`
+
+Download the UMD-bundle from [wzrd.in](https://wzrd.in/standalone/raf@latest) (remember to include the current version number in the filename).
+
+Then include it via a script tag:
+
+```html
+<script src="raf-x.x.x.js"></script>
+```
+
+The API will be available on `window.raf`.
+
+## API
+
+[Documentation at Mozilla Developer Network](https://developer.mozilla.org/en-US/docs/Web/API/window.requestAnimationFrame), [W3 Specification](http://www.w3.org/TR/animation-timing/#requestAnimationFrame)
+
+### var handle = raf(callback)
+
+`callback` is the function to invoke in the next frame. `handle` is a long integer value that uniquely identifies the entry in the callback list. This is a non-zero value, but you may not make any other assumptions about its value.
+
+### raf.cancel(handle)
+
+`handle` is the entry identifier returned by `raf()`. Removes the queued animation frame callback (other queued callbacks will still be invoked unless cancelled).
+
+### raf.polyfill([object])
+
+Shorthand to polyfill `window.requestAnimationFrame` and `window.cancelAnimationFrame` if necessary (Polyfills `global` in node).
+
+Alternatively you can require `raf/polyfill` which will act the same as `require('raf').polyfill()`.
+
+If you provide `object` the polyfills are attached to that given object, instead of the inferred global.
+Useful if you have an instance of a fake `window` object, and want to add `raf` and `caf` to it.
