Delivery Solution is a .NET 7 application that provides endpoints to manage deliveries. It is following the DDD pattern. It consists therefore of 4 main projects:
DeliveryApi: the API layer that exposes the endpoints.DeliveryDomain: the business logic layer that contains the domain models and services.DeliveryInfrastructure: the infrastructure layer that deals with data persistence using MongoDB and message queues using RabbitMQ.DeliveryBackground: the background task that updates expired deliveries state every hour.There are also 3 Unit Tests projects:
DeliveryApiTests: tests the Delivery endpoints.DeliveryDomainTests: tests the business logic.DeliveryInfrastructureTests: tests the database and message broker operations.Available Endpoints
To interact with the API endpoints, you can use tools like Postman or cURL.
Users
POST /users/authenticate - Authenticate user.GET /users - Gets paged users.GET /users/{userID} - Gets the user by user id.Deliveries
