Architecture Exercises

Architecture Exercises

Apply clean architecture principles and common design patterns through these exercises.

Exercises in This Section

Exercise	Difficulty	Time	Description
Clean Layers	Easy	20 min	Structure code with domain, application, and infrastructure layers
Repository Pattern	Medium	25 min	Implement the repository pattern with interfaces
DI Container	Hard	30 min	Build a simple dependency injection container

Key Concepts Covered

• Clean Architecture: Separating concerns into layers
• Dependency Rule: Inner layers don’t depend on outer layers
• Repository Pattern: Abstracting data access
• Dependency Injection: Providing dependencies from outside
• Interface Segregation: Small, focused interfaces

Prerequisites

Before starting these exercises, you should be comfortable with:

• Go interfaces
• Structs and methods
• Chapter 8: Clean Architecture in Go
• Chapter 9: Dependency Injection

Tips

1. Start from the domain layer and work outward
2. Define interfaces at the point of use, not implementation
3. Keep your domain entities free of infrastructure concerns
