Can I use alias with NodeJS require function?

It is possible (tested with Node 8.9.4):

const {foo: f, bar: b} = require('module');
console.log(`${f} ${b}`); // foo bar

Yes, a simple destructure would adhere to your request.

Instead of:

var events = require('events');
var emitter = new events.EventEmitter();

You can write:

const emitter = {EventEmitter} = require('events');

emitter() will alias the method EventEmitter()

Just remember to instantiate your named function: var e = new emitter(); 😁

Sure, just use the object destructuring syntax:

 const { old_name: new_name, foo: f, bar: b } = require('module');
