Example of how to import, export, and utilize functions

require.js

// Load required packages
var User = require('../models/user');
var dbHelper = require('./dbHelper');
var jwt = require('jsonwebtoken'); // used to create, sign, and verify tokens

/* 
EXPORTING FUNCTIONS
Function from the dbHelper.js file.
Saves object information to database and returns the apropiated results. 
*/
var objSave = function (object, res, msg) {
  object.save(function (err) {
    if (err) {
      resMsg(res, 400, false, err, null);
    } else {
      resMsg(res, 200, true, msg, object);
    }
  });
};
exports.objSave = objSave;

/* EXAMPLE OF USING IMPORTED FUNCTIONS
 * Finds All Users
 * Returns a list of all users when found.
 * Accessed at GET /api/users
 */
exports.getUsers = function (req, res) {
  var ok = 'The list of users has been succesfully generated.';
  var noOk = 'No users has been created yet.';
  var auth = 'You are not an admin.';
  var obj = {};

  dbHelper.getData(req, res, User, obj, ok, noOk, auth);
};
