Better local require() paths for Node.js

Problem

When the directory structure of your Node.js application (not library!) has some depth, you end up with a lot of annoying relative paths in your require calls like:

const Article = require('../../../../app/models/article');

Those suck for maintenance and they're ugly.

Possible solutions

// ES6 version using asynchronous iterators, compatible with node v10.0+

const fs = require("fs");
const path = require("path");

async function* walk(dir) {
    for await (const d of await fs.promises.opendir(dir)) {
        const entry = path.join(dir, d.name);
        if (d.isDirectory()) yield* walk(entry);
        else if (d.isFile()) yield entry;

// This event emitter emits events, but reserves the right to publish events to
// for its creator. It uses a WeakMap for true encapsulation.

const eesToEventMaps = new WeakMap();

export default class EventEmitter {
    constructor(publisher) {
        const eventMap = Object.create(null);
        eesToEventMaps.set(this, eventMap);

// === Arrays

var [a, b] = [1, 2];
console.log(a, b);
//=> 1 2


// Use from functions, only select from pattern
var foo = () => [1, 2, 3];

'use strict';

//npm install gulp gulp-minify-css gulp-uglify gulp-clean gulp-cleanhtml gulp-jshint gulp-strip-debug gulp-zip --save-dev

var gulp = require('gulp'),
	clean = require('gulp-clean'),
	cleanhtml = require('gulp-cleanhtml'),
	minifycss = require('gulp-minify-css'),
	jshint = require('gulp-jshint'),
	stripdebug = require('gulp-strip-debug'),
