single-events-eventemitter

When you have to use the Node.js event API, you have to create an instance of EventEmitter. If a module B has to listen event emitted from module A, you can simply require A in B and do something like this:

moduleA.on('notification', function () {
  // Do something
});

But if you need an single instance shared by multiple emitters and listeners (kind of an event bus) then you need to wrap your instance in a module like this:

var EventEmitter = require('events').EventEmitter;
var eventEmitter = new EventEmitter();
module.exports = eventEmitter;

These 3 lines of code are exactly what this package will spare you and it's its sole purpose :wink:
