title: node.js modules: Async vs Fibers.promise vs Q_oper8
body: <p>Just wondering if anyone could give me a comparison of trade-offs between these modules for handling async events. Specifically, I'm interested in knowing about reasons to use Async instead of Fibers.promise, which I am using quite extensively at least in my test code right now. In particular, one of the major pluses I see in Fibers.promise is that I can keep the stack chain front bifurcating, making it possible to use <code>try { } catch { } finally</code>, and also allowing me to ensure that after a request has been handled that the response is ended.</p>
  
  <p>Is anyone using Q_oper8? I found this on another page and was just wondering if that's already dead or if its something I should check out.</p>
