Better local require() paths for Node.js

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.

	$client = new GuzzleHttp\Client(['base_uri' => 'http://httpbin.org']);
