Connecting to MongoDB in Node.js

⭕ Overview
Hello, this is Christian. In this video, we're going to connect to a MongoDB database system using the MongoDB library for Node.js. Before we dive into the coding, let's review the CRUD operations (Create, Read, Update, Delete) for MongoDB, which are essential for interacting with the database.
We'll start by visiting the MongoDB documentation website, where you'll find detailed explanations and examples for each CRUD operation. The left navigation menu provides links to perform operations like insert, select (query), update, and delete.
In this session, I'll demonstrate how to use JavaScript functions to perform these operations. If you need a refresher, all the information is available on the MongoDB documentation site.
Before we begin coding, ensure that MongoDB is running on your system. We'll use MongoDB Compass, a graphical interface that makes it easy to interact with your database. If you haven't installed it yet, make sure to do so. Compass is the preferred tool for managing MongoDB databases.
In my previous exercises, I've created a database called "Unit6DB" with a collection named "students" where I've already inserted about 100 records for testing purposes. You can create any database and collection of your choice for this demo, but I'll be using my pre-existing setup to perform the CRUD operations.
We'll keep MongoDB Compass running to visualize our data as we perform these operations. This will help you see the real-time impact of the code we write.
By the end of this tutorial, you'll be comfortable connecting to a MongoDB database using Node.js, performing CRUD operations, and using MongoDB Compass to manage and visualize your data.
Note: For local MongoDB databases, use the IP address "127.0.0.1" instead of "localhost" because Node.js 18 and up prefer IPv6 addresses. This means, on many machines, Node.js will resolve "localhost" to the IPv6 address "::1" and it might be unable to connect, unless the mongodb instance is running with ipv6 enabled.
