Can I use alias with NodeJS require function?

Question

I have an ES6 module that exports two constants:

export const foo = \"foo\";
export const bar = \"bar\";

I can do the following in another

Answer 1

It is possible (tested with Node 8.9.4):

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

Answer 2

I would say it is not possible, but an alternative would be:

const m = require('module');
const f = m.foo;
const b = m.bar;

Answer 3

Sure, just use the object destructuring syntax:

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

Answer 4

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();
