What is a promise?

Go to model

User.prototype.login = function(){
  return new Promise((resolve, reject) => {
		this.cleanUp()
	  	usersCollection.findOne({username: this.data.username}, (err, attemptedUser) => {
		if(attemptedUser && attemptedUser.password == this.data.password){

resolve("congrats")

	this.validate()

// 2. Only if there are not validation errors, then save user data into db

What is a model?

Where we enforce rules or business logic.

User registration is what we are doing.

First we need to make sure that userController can access the data that is submitted in the form.

Go to app.js

What is a controller?

The router should not contain the functions.

Router should just be a list of routes.

Controller should have the functions.

In the root create dir controllers.
