MicroServices

MicroServices

This project is a microservices-based architecture implemented using .NET 8 and Entity Framework Core. The solution consists of three micro-services: UserService, ProductService, and OrderService. MainService handle interactions between these services using Ocelot API Gateway where each is responsible for its own domain.

Services

MainService

• Description: Orchestrates operations across UserService, ProductService, and OrderService.
• Endpoints:
  • POST GET /users/{id} to /api/users/{id}
  • POST GET /products/{id} to /api/products/{id}
  • POST GET /orders/{id} to /api/orders/{id}

UserService

• Endpoints:
  • GET /api/users - Retrieve all users.
  • GET /api/users/{id} - Retrieve a user by ID.
  • POST /api/users - Add a new user.

ProductService

• Endpoints:
  • GET /api/products - Retrieve all products.
  • GET /api/products/{id} - Retrieve a product by ID.
  • POST /api/products - Add a new product.

OrderService

• Endpoints:
  • GET /api/orders - Retrieve all orders.
  • GET /api/orders/{id} - Retrieve an order by ID.
  • POST /api/orders - Create a new order.
  • GET /api/orders/details/{id} - Retrieve order details, including user and product information.
    • Details: Reaches UserService and ProductService. Uses GET /api/users/{id} and GET /api/products/{id} from these services to retrieve user and product information.

Configuration

Each service has its own database context and is configured to use Entity Framework Core for data access. The services are set up to communicate with each other through HTTP requests.

MainService

• Port: 7133
• DTOs: UserDto, ProductDto, OrderDto
• Dependencies: Requires UserService, ProductService and OrderService to be running.
  • Note: MainService simplifies the interaction with the microservices by providing a unified interface.

UserService

• Port: 7188
• Database Context: UserContext
• Models: User

ProductService

• Port: 7197
• Database Context: ProductContext
• Models: Product

OrderService

• Port: 7138
• Database Context: OrderContext
• Models: Order

Swagger

Each service includes Swagger for testing. You can access these at the following URLs:

• UserService: https://localhost:7188/swagger
• ProductService: https://localhost:7197/swagger
• OrderService: https://localhost:7138/swagger

Postman

Each service is accessible from MainService. You can access these by making GET or POST request in Postman:

• UserService: https://localhost:7133/users/
• ProductService: https://localhost:7133/products/
• OrderService: https://localhost:7133/orders/
