title: Queue tasks in Node
body: <p>I'm building a node application that will act as a "worker" to scaffold out a new application and then upload the application to AWS. There are 5 tasks that complete the scaffold cycle.</p>
  
  <p>I'd like to know if it's possible in Node/Express to queue incoming requests and then start the scaffold cycle for requests in the queue when the cycle has successfully completed. There should only be one scaffold cycle running at one time.</p>
