Angular Delayed Queue

Implementation of simple delayed queue for Angular. Note that you should create an instance of the queue to use it.

The queue accepts a delay for each item and returns a promise. It also makes sure no item from the same queue is being executed in the same time.

Instance init options object:

isAutoExecutable - (optional, default: false) if the queue will start executing once an item is added
defaultDelay - (optional) Default delay for all items, can be overwritten for a specific item

Usage example A:

var queue = new Queue({ isAutoExecutable: true });

queue.enqueue().then(function() {
	console.log("foo");
});

queue.enqueue().then(function() {
	console.log("bar");
});

Usage example B:

var config = {
	defaultDelay: 500
};

var queue = new Queue();

queue.enqueue(1000).then(function() {
	console.log("foo");
	queue.executeNext();
});

queue.enqueue().then(function() {
	console.log("bar");
	queue.executeNext();
});

queue.executeNext();
