API

• startPolling(worker_callback, error_callback)
  • worker_callback is passed two arguments (message, callback) where message is an Object containing data and callback is a function that must be called when you are finished processing the message. If you pass an Error into the callback then error_callback will be called with your error. If you do not pass an Error into the callback then the message will be removed from the queue.
  • error_callback is passed one argument (error) where error is an Error.
• stopPolling(stop_callback)
  • stop_callback is passed no arguments. It will be called once the queue has stopped polling. If you currently have a message in progress, it will wait until that message is processed before stopping.
