How to make global eventEmitter in node.js server (express 4.x) ?

Question

Node.js

Greetings.
I want to make an eventEmitter that will be available in any module. What is the best way to organize it? Is there a 'best practice' for this case?
I 'm using express 4.x
PS tried this, didn't work:

var events = require('events');
global.eventEmitter = new events.EventEmitter();
global.eventEmitter.emit('testEvent');

Answer 1

Best practice for express is app.locals .
