Assignment 01: Notes Management REST API

Directory: notes-app/
Description: The first assignment focuses on the fundamentals of backend development. It involves establishing a connection to MongoDB, defining a Mongoose schema, setting up an MVC architecture, and implementing standard CRUD operations with the correct HTTP methods.

Key Concepts:

• REST API Design
• Database connection
• Schema design
• MVC (Model-View-Controller) pattern
• CRUD operations (GET, POST, PUT, PATCH, DELETE)

Assignment 02: Advanced Routing & Queries

Directory: advanced-routing-queries/
Description: This assignment extends the basic CRUD functionality built in Assignment 01 by introducing advanced MongoDB querying techniques and complex routing scenarios.

Key Concepts:

• Route parameters vs. Query parameters
• MongoDB sorting algorithms
• Pagination implementation (Limit, Skip, Total Pages)
• Filtering records dynamically via query parameters

---

Assignment 03: Search APIs

Directory: search-assignment/
Description: The final assignment of this series combines all previously learned concepts with search functionalities using MongoDB's $regex operator. It involves writing master endpoints that can search, filter, sort, and paginate all simultaneously.

Key Concepts:

• MongoDB $regex for case-insensitive and partial string matching
• Combining queries using $or and other logical operators
• Complex query parameters parsing
• Building dynamic filters alongside sorting and pagination parameters

General Setup Instructions

Each project is fully standalone. To run any of the projects locally:

1. Navigate to the desired project directory (e.g., cd notes-app).
2. Run npm install to install all necessary dependencies.
3. Create a .env file referencing the provided .env.example file and insert your MongoDB URI.
4. Run the development server with npm run dev.

Note: You can find a Postman collection in the Assignment 03 folder to test the advanced endpoints directly.
