[![Build Status](https://travis-ci.org/taisuke-j/easing-animation-frames.svg?branch=master)](https://travis-ci.org/taisuke-j/easing-animation-frames)

This is a tiny library for creating CPU-friendly easing animations with [requestAnimationFrame](https://developer.mozilla.org/en-US/docs/Web/API/window/requestAnimationFrame) API and [Robert Penner's easing equations](http://robertpenner.com/easing/). Suggestions and pull requests for optimization are welcome.

![Bar Animation](https://raw.githubusercontent.com/wiki/taisuke-j/easing-animation-frames/images/readme-bar.gif)

Select an easing type (`cubicInOut` by default) and pass a callback function to run for every animation frame which manipulates target DOM elements.

  template: updateBarWidth // Callback function to run for every frame, which receives progress from 0 to 1

  easingType: "quadInOut", // Easing function name

  duration: 3, // Animation duration in milliseconds

  duration: 3000, // Animation duration in milliseconds

  template: updateBarWidth, // Callback function to run for every frame, which receives progress from 0 to 1

  complete: animationComplete, // Callback funciton to run on completion

Duration is set to be 4,000 milliseconds by default, which you can change. Once the animation starts, the callback function (template) receives the progress value (from 0 to 1) that you can use to render the animation. The example above uses `(progress * 75)`% for the width of the bar, based on the time passed.

The template function also provides `stop` and `resume` functions, if you want to stop the animation before it completes and resume it.

[React Easing Animation](https://github.com/taisuke-j/react-easing-animation) is a React HOC implementation of this library.

It uses `requestAnimationFrame`, which should be supported for [most of the modern browsers](https://caniuse.com/#feat=requestanimationframe).
