PromiseQueue
Summary
PromiseQueue Queues and executes asynchronous functions in sequential order.
Functions added to the queue must return an Promise object. Each function will only be executed after the previous function's promise has resolved.
Example: function asyncMethod(endpoint) { var promise = new Promise(); jsonp.get(endpoint).done(promise.resolve, promise); return promise; }
var pq = new PromiseQueue(); pq.queue(asyncMethod('firstEndpoint')); pq.queue(asyncMethod('secondEndpoint')); // will not call method until first method resolves
pq.dequeue(); // starts running the queue
