# single-events-eventemitter

[![Build Status](https://travis-ci.org/ncuillery/single-events-eventemitter.png)](https://travis-ci.org/ncuillery/single-events-eventemitter)

When you have to use the [Node.js event API](https://nodejs.org/api/events.html), 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:

```javascript

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:

```javascript

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:
