Clean Tickets

Clean Tickets is a simple event ticketing system built on ASP.NET Core 6, Entity Framework Core and using Minimal API.

The application is designed to be a small service working together with other components through events. Even though there is no actual implementation of any messaging system in place right now, it is intended to be event-driven.

Architecture

This project follows the Clean Architecture patterns with some slight changes. It implements Command and Query Separation by implementing disparate ICommand and IQuery interfaces and handlers. While it does currently use a mediator to mediate between incoming messages and their handlers, it should be fairly easily changed to a non-mediated broker.

Another departure from common Clean Architecture implementations is the fact that the domain repositories are contained in the domain assembly. A good number of implementations place these in the Application layer instead, but I feel that the domain models, as well as the repositories that abstract their interactions should be in the domain layer. I'm still on the fence about this one though.

Structure

The solution consists of four projects:

• Application contains the use cases and features
• Domain contains the domain models (entities)
• Infrastructure.Persistence contains the Entity Framework persistence code
• Api contains an implementation of a front-end for the application layer, supporting its basic operations using Minimal API

Tests

The solution also includes a test project for the various command and queries implemented by the application layer.
