🧩 Design Patterns

Gravy employs modern and proven architectural and design patterns:

1. Clean Architecture

   • Enforces separation of concerns to ensure long-term maintainability.
   • Divides the project into Domain, Application, Infrastructure, and Presentation layers.

2. Domain-Driven Design (DDD)

   • Focused on the core domain logic and encapsulating business rules.

3. Outbox Pattern

   • Ensures reliable event publishing to external systems using transactional outboxes.

4. Repository Pattern

   • Abstracts database access logic for cleaner and more testable code.

5. Result Pattern

   • Provides a standardized way to handle operation results, making it easier to deal with success and failure cases.

6. Idempotency

   • Ensures that operations can be performed multiple times without different outcomes, which is crucial for reliability in distributed systems.

7. CQRS (Command Query Responsibility Segregation)

   • Separates read and write operations to optimize performance and scalability.

8. Logging

   • Implements comprehensive logging to capture important events and errors, aiding in monitoring and debugging the application.

📖 Usage

Example: Creating a New Order

Here’s a simple example of how to create a new order:

using Gravy.Application.Services;  
using Gravy.Domain.Entities;  

// Use the factory method to create a new order
var order = OrderCreate(
    Guid.NewGuid(),
    Guid.NewGuid(),
    Guid.NewGuid(),
    DeliveryAddress.Create(
      "street",
      "city",
      "state",
      Location.Create(
      10.0,
      12.0
   )
);

---
