This introductory guide teaches you how to construct a basic backend for a website using popular technologies like Node.js, Express.js, and the MongoDB NoSQL database. The tutorial covers the core components of backend development, walking you through the initial server setup, database connection, and code structure using a model, route, and controller pattern. You will learn to build practical APIs for user authentication, including password hashing, as well as full CRUD (Create, Read, Update, Delete) operations to manage data. Finally, the video demonstrates how to utilize Postman to test your server's requests and ensure your APIs are functioning correctly.
