NestJS Advanced REST API with MongoDB

This repository contains an advanced project demonstrating the use of NestJS with MongoDB for building robust RESTful APIs. The project includes best practices for designing scalable APIs, leveraging MongoDB's flexible document model, and using NestJS decorators and modules to create clean and maintainable code.

Project Overview

This project aims to showcase how to create a production-ready REST API using NestJS and MongoDB. It includes:

1. Advanced MongoDB Integration: Efficient database handling using Mongoose with NestJS, including schema design, query optimizations, and indexing.
2. RESTful API Design: Implementing RESTful endpoints following best practices, including CRUD operations, error handling, and authentication.
3. Scalability and Maintainability: Utilizing NestJS modules, services, and controllers to ensure the project is scalable and easy to maintain.
4. Validation and Error Handling: Advanced data validation using NestJS decorators and handling errors gracefully with appropriate HTTP status codes.

Content

The project is divided into the following main modules:

1. User Module: Handles user registration, authentication (JWT-based), and profile management.
2. Product Module: Manages CRUD operations for product listings, integrating advanced MongoDB queries for filtering, sorting, and pagination.
3. Order Module: Implements order creation, updating, and management, showcasing nested relations between users and products.
4. Error Handling Module: Centralized error management for REST API with custom error classes and HTTP responses.
5. Authentication & Authorization: Secure authentication using JWT and role-based access control to restrict certain endpoints.
