Package Exports

rafl

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (rafl) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

rafl

A fork of the seemingly-abandoned component/raf with added support for IE 11, web workers, and node.

Install

$ npm install rafl

Example

Request the animation frame with raf(fn), cancel with raf.cancel(id).

var raf = require('rafl')

var x = 0
var y = 50
var canvas = document.querySelector('canvas')
var ctx = canvas.getContext('2d')

function animate() {
  raf(animate)
  draw()
}

var prev = Date.now()
function draw() {
  var curr = Date.now()
  var diff = curr - prev
  var p = diff / 16
  ctx.clearRect(0, 0, 900, 300)
  ctx.beginPath()
  ctx.globalAlpha = .5
  ctx.arc(x, y, 10, 0, Math.PI * 2, false)
  ctx.fill()
  x += 2
  y += Math.sin(x/20) * 5
  prev = curr
}
