delay	Integer	100	Minimal delay between queue calls
persistent	Boolean	false	Whether the queue persists when queue is empty
max_concurrent	Integer	-1	How many concurrent callbacks can run at once, a.k.a throttle
complete	Integer	null	Optional complet callback, note: the callback is never used when persistent is set to true
paused	Integer	false	Whether to start the queue automatically or not

Usage

Include angular-queue.js after your main AngularJS script.

Specify ngQueue as a dependency for your Angular application:

var app = angular.module('myApp', ['ngQueue']);

In your controller, services, etc, inject $queue, and create an instance to use:

app.controller("MyCtrl", ['$queue',
    function($queue){
        var myCallback = function(item) {
                console.log(item);
            },
            options = {
                delay: 2000, //delay 2 seconds between processing items
                paused: true, //start out paused
                complete: function() { console.log('complete!'); }
            };
        
        // create an instance of a queue
        // note that the first argument - a callback to be used on each item - is required
        var myQueue = $queue.queue(myCallback, options);
            
        myQueue.add('item 1'); //add one item
        myQueue.addEach(['item 2', 'item 3']); //add multiple items
        
        myQueue.addFirst('item 1'); //push one item on top of the pile
        myQueue.addEachFirst(['item 2', 'item 3']); //push  multiple items on top of the pile
        
        myQueue.start(); //must call start() if queue starts paused
    }]
);
