EShopMicroServices

This repository showcases a fully functional e-commerce microservices application built with .NET 8, following Domain-Driven Design (DDD), Command Query Responsibility Segregation (CQRS), and Clean Architecture principles. The project is developed as part of the Udemy course.

📦 Project Overview

The application is composed of several independent microservices, each responsible for a specific business capability. The services communicate asynchronously using RabbitMQ and are orchestrated through a YARP API Gateway. The architecture emphasizes scalability, maintainability, and separation of concerns.

🧩 Microservices Implemented

• Catalog Service: Manages product information using Marten with PostgreSQL.
• Basket Service: Handles shopping cart operations with Redis for caching.
• Discount Service: Applies discounts to products, utilizing gRPC for communication.
• Ordering Service: Processes orders and integrates with SQL Server.
• API Gateway: Routes requests to appropriate services using YARP.
• WebUI: ASP.NET Core Razor Pages application consuming APIs via Refit.

🛠️ Technologies Used

• .NET 8: Core framework for building the services.
• ASP.NET Core Web API & Minimal APIs: For creating RESTful services.
• Entity Framework Core & Marten: Data access technologies.
• PostgreSQL, Redis, SQLite, SQL Server: Data storage solutions.
• RabbitMQ & MassTransit: For asynchronous messaging.
• gRPC: High-performance RPC framework.
• YARP: API Gateway implementation.
• Docker & Docker Compose: Containerization and orchestration.
• Swagger: API documentation.
• Serilog: Structured logging.
• Health Checks: Monitoring service health.

🧱 Architectural Patterns

• Domain-Driven Design (DDD): Focuses on the core domain and domain logic.
• Command Query Responsibility Segregation (CQRS): Separates read and write operations.
• Clean Architecture: Enforces separation of concerns and dependency inversion.
• Vertical Slice Architecture: Organizes code by feature for better modularity.
