This lab series introduces how to build a Node.js + MongoDB application from the ground up — starting with a cloud database, then connecting it through Express and Mongoose, and finally creating a full REST API with CRUD operations.

The lab is divided into three main parts:

You’ll learn how to:

• Create and configure a MongoDB Atlas account.
• Deploy your first database cluster using the free plan.
• Add collections and documents (DBFilms → ColFilms).
• Obtain and configure your database connection string for Node.js.

📄 See file: part1.md

You’ll continue by developing a small API called MiniFilms, connecting it to the MongoDB database using the Mongoose library.

You’ll learn how to:

• Scaffold an Express project.
• Organize your project with routes and models.
• Define a Mongoose schema for films.
• Fetch and display data from your MongoDB Atlas cluster.

📄 See file: part2.md

You’ll create a fully functional CRUD microservice called MiniPost that performs:

• Create, Read, Update, Delete operations
• Connection to MongoDB Atlas via Mongoose
• Route handling with Express
• Environment configuration using dotenv
