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

tmux shortcuts & cheatsheet

start new:

tmux

start new with session name:

tmux new -s myname

	#!/bin/bash
	#Source https://michaelryom.dk/custom-ddns-on-ubiquiti-usg/
	cat << 'EOF' > /etc/cron.hourly/ddns
	#!/bin/bash
	IP=$(curl -s -L "http://ipv4.myip.dk/api/info/IPv4Address" \| sed -e 's/^"//' -e 's/"$//')
	curl -s -L "https://api.unoeuro.com/ddns.php?apikey=<API key>&domain=<Domain>&hostname=<Sub domain>&myip=$IP" \| logger
	EOF

	chmod +x /etc/cron.hourly/ddns

	#!/bin/bash
	set -e

	show_help() {
	cat << EOF

	# Mac OS X Lion introduced a new, iOS-like context menu when you press and hold a key
	# that enables you to choose a character from a menu of options. If you are on Lion
	# try it by pressing and holding down 'e' in any app that uses the default NSTextField
	# for input.
	#
	# It's a nice feature and continues the blending of Mac OS X and iOS features. However,
	# it's a nightmare to deal with in Sublime Text if you're running Vintage (Vim) mode,
	# as it means you cannot press and hold h/j/k/l to move through your file. You have
	# to repeatedly press the keys to navigate.
