title: Equivalent of NSNotificationCenter for React Native?
body: <p>Been searching for a while to see if there's anything built-in or any 3rd party modules for adding NSNotificationCenter style functionality to a react-native app.</p>
  
  <p>Specifically, I want modules to "listen" for certain notification types, and I will be able to "broadcast" events from other parts of the app (from within javascript).</p>
  
  <p>The closest thing I've found is this from 3 days ago: <a href="https://stackoverflow.com/a/32004456/798533">https://stackoverflow.com/a/32004456/798533</a>, but it only supports sending NSNotificationCenter events, not listening.</p>
