ProductService

Welcome to the ProductService repository. This project is a sample implementation of Domain-Driven Design (DDD), Command Query Responsibility Segregation (CQRS), and Clean Architecture using .NET. It demonstrates a modern approach to building scalable and maintainable applications.

Overview

ProductService is designed to manage product-related operations in an e-commerce system. The project adheres to the following architectural principles:

• Domain-Driven Design (DDD): Organizes code around the business domain, ensuring a clear separation of concerns and encapsulation of business logic.
• CQRS (Command Query Responsibility Segregation): Separates read and write operations to optimize performance and scalability.
• Clean Architecture: Ensures that the application is structured in a way that maintains a separation between core business logic and external concerns.

Key Features

• Fluent Validation: Implemented for validating inputs in a fluent and expressive manner. Internal Message Queue: Uses .NET channels to handle internal messaging and communication between components. Domain Event Handlers: Processes domain events to trigger actions or updates based on changes in the domain model. CQRS with MediatR: Utilizes MediatR for implementing the CQRS pattern, handling commands and queries in a decoupled manner. Architecture

• Domain Layer Entities: Core business objects representing concepts like Product. Value Objects: Immutable types representing attributes with business logic. Aggregates: Consist of entities and value objects to enforce consistency rules.

• Application Layer Commands and Command Handlers: Defines actions and their corresponding handlers for processing write operations. Queries and Query Handlers: Defines read operations and their handlers for fetching data.

• Infrastructure Layer Repositories: Implement data access logic and repository patterns to interact with data sources. Message Queue: Implements internal messaging using .NET channels for asynchronous communication.

• Presentation Layer API Controllers: Expose endpoints for interacting with the service, handling HTTP requests and responses.

• Validation Fluent Validation is used to ensure that inputs meet the required specifications before processing.

• Internal Messaging Internal communication between components is handled using .NET channels. This provides a scalable approach to managing asynchronous tasks and events.

• Domain Events Domain events are published and handled to manage changes in the domain model. This allows for decoupled and efficient processing of domain-related actions.
