Hey there, fellow programmer!

Welcome to the Intermediate Node.js course! If you are taking this course, I am assuming you know the basics of Node.js and Express.js. If not, a good place to start is the intro to node and express course, here on GitHub Learning Lab.

In this tutorial, you will learn how to connect your server to a NoSQL database called MongoDB. You will also learn how to refactor repetitive code, to make it easier to maintain. By the end of this you have a Rest API that can Create, Read, Update, and Delete (CRUD) documents in MongoDB.

This is an interactive tutorial. At the end of each section, you will be prompted to do something to continue. If you don't get a response right away, try refreshing your browser.

Let's start by making a User model for mongodb using the mongoose library. This will be the template used to describe what each individual document will look like in our collection.

Find the "models" directory in the root of your project and open "User.js", then add this code to it:

const mongoose = require('mongoose');

const UserSchema = new mongoose.Schema({
  name: { type: String, required: true },
  email: { type: String, required: true, unique: true },
  password: { type: String, required: true }
});

module.exports= mongoose.model('User',UserSchema)

Looks like a JS object doesn't it? That is one of the cool things about MongoDB, it is easy to transfer data from the frontend to the backend. Think of this as a factory, or mold, that can create new User documents in a User collection.

Looking at the model above, which key (name, email, or password) needs to have unique values?
