SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Hexagonal architecture isolates business rules from frameworks, IO, and persistence details by using ports and adapters, improving testability and maintainability.

Core Features & Use Cases

  • Domain model and use cases that orchestrate workflow through clear port contracts
  • Inbound/outbound ports that define boundaries between domain and infrastructure
  • Adapters that implement ports and connect to external systems
  • An explicit composition root that wires concrete adapters to use cases

Quick Start

Define a single-use-case boundary with input/output DTOs and start wiring with explicit ports and adapters.

Frequently Asked Questions about hexagonal-architecture

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I decouple business logic from infrastructure using ports and adapters?▼

Hexagonal architecture isolates business rules from frameworks and IO using ports and adapters, ensuring infrastructure changes do not affect core domain logic or testability.

Can I use hexagonal architecture with TypeScript, Java, Kotlin, and Go projects?▼

Yes, hexagonal architecture applies across multi-language projects including TypeScript, Java, Kotlin, and Go, standardizing domain, application, and adapter layers regardless of the implementation language.

How do I structure a use case with input and output DTOs in hexagonal architecture?▼

Structure a use case by defining a single boundary with input and output DTOs, orchestrating workflow through explicit outbound ports, and wiring concrete adapters at the composition root.

Does hexagonal architecture support testability through mockable ports?▼

Yes, hexagonal architecture supports testability through mockable ports by defining explicit boundaries between the domain and infrastructure, allowing adapters to be replaced with mocks during testing.

What is the best way to isolate domain rules from frameworks and persistence details?▼

The best way to isolate domain rules from frameworks and persistence details is applying hexagonal architecture, which wraps the domain with ports and connects external systems through adapters.

When should I not use hexagonal architecture for software design?▼

You should avoid hexagonal architecture when the domain logic is minimal or when the overhead of defining explicit ports, adapters, and a composition root outweighs the maintainability benefits for small applications.
