E-Commerce Microservices Project

Overview

This project is an e-commerce application built using a microservices architecture. It consists of separate services for Products, Orders, Admin, and Image management, all orchestrated through an API Gateway.

Project Architecture

Technical Stack

• Framework: Spring Boot
• Containerization: Docker
• Message Broker: Apache Kafka
• Databases: PostgreSQL (or other SQL databases)
• API Gateway: Spring Cloud Gateway
• Frontend: React.js using Vaadin for connecting to springboot

Microservices

1. Auth Service: Handles user/admin auth & authorization.
2. Products Service: Manages product information and inventory.
3. Orders Service: Handles order processing and management.
4. Admin Service: Provides administrative functionalities.
5. Image Service: Manages product images.

Key Features

• Microservices architecture for scalability and maintainability
• Docker containerization for easy deployment and scaling
• API Gateway for centralized request handling
• Asynchronous communication between services using Kafka
• Separate databases for each microservice
• Frontend shopping cart functionality
• Auth and Authorization for Role based access to various services.

Database Schemas

Products Table

• id (INT PRIMARY KEY)
• name (VARCHAR(255) NOT NULL)
• description (TEXT)
• price (DECIMAL(10,2) NOT NULL)
• stock (INT NOT NULL)
• image_id (VARCHAR(50) NOT NULL)

Orders Table

• id (INT PRIMARY KEY)
• order_date (DATETIME NOT NULL DEFAULT CURRENT_TIMESTAMP)
• total_price (DECIMAL(10,2) NOT NULL)
• (Foreign Key references to Products for ordered items)

Images Table (Optional)

• id (VARCHAR(50) PRIMARY KEY)
• name (VARCHAR(255))
• mime_type (VARCHAR(50))
• (Additional metadata fields as needed)

Communication

• RESTful APIs for most service-to-service communication
• Kafka for asynchronous events (e.g., order placement, product deletion)

Deployment

The entire application is deployable using Docker Compose, which sets up all microservices and their respective databases.

Getting Started

1. Clone the repository
2. Navigate to the project root directory
3. Run docker-compose up to start all services
4. Access the application through the API Gateway endpoint
