What You'll Learn
- Analyze layered architecture pitfalls (database-driven design, shortcuts, testing, hidden use cases, parallel work)
- Apply SRP and Dependency Inversion to isolate business rules from web and persistence concerns
- Design hexagonal architecture using ports and adapters to decouple the application core from external systems
- Organize code by feature with an architecturally expressive package structure (domain, application, adapters)
- Implement domain models and use cases with dedicated input/output models and validation rules
- Build web and persistence adapters with sliced controllers/ports and transaction boundaries
- Plan and implement tests across the test pyramid for domain, use cases, and adapters

About this course
WHY I WROTE THIS COURSE
This course will teach you all about creating a web application in the Hexagonal Architecture style. Hexagonal Architecture promotes the separation of concerns by encapsulating logic in different layers of the application. This enables a higher level of isolation, testability, and control over your business specific code.
You will learn how to design software modules and complete applications in a clean and maintainable manner, while also learning how to advocate for a certain technique given your application and constraints.
By the end of this course, you will have a greater understanding of how to implement software architecture, a key skill for any senior developer.
