Features

• Microservices Architecture: Modular and scalable structure with separate services for products, users, and orders.
• RESTful APIs: CRUD operations for products, user management, and order processing.
• JWT Authentication: Secure user authentication and authorization.
• MongoDB Integration: Persistent data storage with Mongoose ORM.
• Dockerized Services: Simplified deployment with Docker and Docker Compose.
• Unit & Integration Testing: Ensure reliability through automated tests.

Architecture

The application consists of three microservices, each responsible for different aspects of the e-commerce platform. The services communicate with each other via RESTful APIs (or optionally through message queues).

Services Overview

1. Product Service

• Manages product data (CRUD operations)
• Routes:
  • POST /products: Create a new product
  • GET /products: Fetch all products
  • GET /products/:id: Fetch a single product by ID
  • PUT /products/:id: Update a product by ID
  • DELETE /products/:id: Delete a product by ID

2. User Service

• Handles user registration, authentication, and profile management
• Routes:
  • POST /register: Register a new user
  • POST /login: Login a user and receive a JWT token
  • GET /profile: Get user profile (JWT protected)

3. Order Service

• Manages order creation and retrieval for authenticated users
• Routes:
  • POST /orders: Create a new order (JWT protected)
  • GET /orders: Get all orders for the authenticated user (JWT protected)

Prerequisites

• Node.js (version 14.x or higher)
• MongoDB (Local instance or cloud service)
• Docker (optional, for containerization)
• Postman or similar tool for API testing
