SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Derives a complete Clean Architecture + DDD technical design from a set of fully dressed, reviewed use cases. The translation is deterministic and ensures alignment between requirements and architecture.

Core Features & Use Cases

  • Identify bounded contexts and aggregates from the use cases.
  • Define domain events, typed errors, interactors, port interfaces, and adapter sketches.
  • Produce a ready directory structure, contract test skeletons, and code patterns in TypeScript and GoLang.

Quick Start

Provide reviewed use cases to generate a complete Clean Architecture and DDD technical design.

FAQPage Schema
How do I translate use cases into Clean Architecture and DDD technical designs?

You translate use cases into Clean Architecture and DDD designs by providing reviewed use cases to derive bounded contexts, aggregates, domain events, and interactor definitions. This deterministic process ensures alignment between requirements and software architecture.

What is the process for deriving bounded contexts and aggregates from use cases?

Deriving bounded contexts and aggregates involves analyzing reviewed use cases to extract domain models, events, and typed errors. This establishes clear boundaries and aggregate roots for your domain-driven design implementation.

Can I generate TypeScript and GoLang code structures from domain-driven design use cases?

Yes, you can generate TypeScript and GoLang code structures from domain-driven design use cases. The design output includes ready directory structures, port interfaces, adapter sketches, and contract test skeletons for both languages.

Do I need fully dressed use cases to generate Clean Architecture interactors and port interfaces?

Yes, you need fully dressed and reviewed use cases to generate Clean Architecture interactors and port interfaces. The translation relies on complete use case requirements to deterministically derive accurate bounded context maps, domain models, and typed errors.

What's the best way to define typed errors and domain events for bounded contexts?

The best way to define typed errors and domain events for bounded contexts is through a deterministic translation from reviewed use cases. This approach derives a complete Clean Architecture technical design, ensuring events and errors align with aggregate boundaries.

When should I not use use cases to derive my software architecture?

You should not use use cases to derive your software architecture if your requirements are not fully dressed or reviewed. The deterministic translation into bounded contexts and interactors depends on complete input to ensure alignment between architecture and requirements.
