cycle-array

Cycle through array values

Use Case

I wanted to create a component that rotated a set of images, looping back to the start.

var Cycle = require('cycle-array'),
    cycle = new Cycle(),
    image = [ '/img1.png', '/img2.png', '/img3.png' ]

myComponent.on('interval', function (state) { 
  state.set('image.url', cycle(image)); // sets image.url to a new image on each call
});

Each call to cycle() will return the next array value, looping back to index 0.

Installation

Download node at nodejs.org and install it, if you haven't already.

npm install cycle-array --save

Notes

I kind of hate the Cycle/new Cycle() pattern, but it was the quickest way to keep multiple instances from stomping on one another. I'm going to revist this with ES6 syntax for fun later.
