Features

This library have almost all features of require("events"), but following is different:

• No events are fired when event listeners are added/removed.
• Asynchronous Event Listeners - The event listeners can return everything that bluebird recognizes as a promise, to say that the listener is performing some asynchronous operations and it is probably not completed, yet.
• Event Listeners Order - The event listeners can be ordered by specifying dependencies. Each listener will be executed only after their dependencies complete execution, that means if those dependencies returned a promise, that promise is resolved.

Documentation

Since this library has compatible interface to require("events") you can guess most of its methods. If not, there is API reference in the GitHub wiki.
