File structure

[Armand-Lluka]

Overall it's very good and you have followed proper protocol. This can be improved further by

Routes - This is where you handle get/post requests, this is then forwarded to the controllers

Models - one file per resource (eg. UserModel.js for interacting with my 'user' table/collection/whatever in my database); all my data models that depend on the db connection object.

Controllers - one file per resource (eg. UserController.js for all route functions for users); all my code that serves my routes
