The code you have now calls doStuff from the same thread where you make your requests. JS wait for callback to finish inside a loop Waiting for javascript async callback @ http post Node.js & Redis; Waiting for a loop to finish. This is most likely a threading issue. I have been told that failing a drug test would result in a call from the clinic and no call back from Target. Lucyphone is the first consumer-driven "virtual queuing" or callback system. Node.js - post response is not waiting for callback to complete I am working on node.js http server. When your call reaches an agent, you will get a call back. There is a great library called Async.js that helps solve problems like this with many async & flow control helpers. I ran into a very similar issue with BLE on Samsung Galaxy S4 devices. The Server is connected to mongodb. Still Waiting on a Callback or Offer(s). Would be great if objective c had promises, but until then, I usually handle things like this with recursion, using the input array as a to-do list.
