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

ANNOUNCEMENT

I have moved this over to the Tech Interview Cheat Sheet Repo and has been expanded and even has code challenges you can run and practice against!

If you are using backbone (and backbone.marionette) in a browserify managed project, you will likely run into issues with underscore (at least if you manage your dependencies with npm). Each package, that has underscore as a dependency, will require its own version of underscore (making your bundle file contain multiple versions of underscore). Back in the days, you could shim backbone and underscore like:

browserify({
	shim: {
		'underscore': {
			path: './node_modules/underscore/underscore.js',
			exports: '_'
 },

This is no longer needed as Emmet supports JSX - you just need to turn it all on. Did a quick tutorial: http://wesbos.com/emmet-react-jsx-sublime/

Thanks, @wesbos

Using emmet in jsx files
Emmet expands text when js autocomplete needed
