Answer 1

In using express, one of the common mistake is by requiring the express before mongoose. This results to "MissingSchemaError: Schema hasn't been registered for model "User"." error.

You can easily fix it by correcting the "require" order (i.e mongoose then express)

var mongoose = require('./config/mongoose'), 
    express = require('./config/express');
