What problem does it solve?
This Skill guides you in implementing proven backend architecture patterns like Clean Architecture, Hexagonal Architecture, and Domain-Driven Design. It solves the problem of building tightly coupled, untestable, and hard-to-maintain systems by promoting clear separation of concerns and technology independence, ensuring your applications are built for longevity and adaptability.
Core Features & Use Cases
- Clean Architecture: Structure your application with clear layers, ensuring business logic is independent of frameworks and databases.
- Hexagonal Architecture: Design systems with "ports and adapters" for easy swapping of infrastructure components and enhanced testability.
- Domain-Driven Design (DDD): Apply strategic and tactical patterns to model complex business domains effectively.
- Use Case: Refactor a monolithic application into a more modular, testable, and maintainable system, preparing it for future microservices decomposition.
Quick Start
Example: Clean Architecture - User Entity
from dataclasses import dataclass
from datetime import datetime
@dataclass
class User:
"""Core user entity - no framework dependencies."""
id: str
email: str
name: str
created_at: datetime
is_active: bool = True
def deactivate(self):
self.is_active = False
