pirocorpsimplecleanarchitecture is a project template that brings clarity and consistency to GitHub repositories by applying well-defined layers. This approach reduces accidental complexity so teams can focus on business logic instead of structural noise.
By aligning domain rules, use cases, and frameworks into explicit layers, the pattern supports testability, maintainability, and smooth onboarding for new contributors on GitHub projects.
| Layer | Responsibility | Typical Location in Repo | Key Artifacts |
|---|---|---|---|
| Domain | Core business rules and models | domain/models, domain/rules | Entities, value objects, domain services |
| Use Case | Application-specific workflows | usecase/interactors, usecase/services | Interactors, application services |
| Interface Adapters | Transform data for frameworks and UI | adapter/http, adapter/repo, adapter/mapper | Controllers, presenters, gateways |
| Frameworks & Drivers | External tools and entry points | main, config, infrastructure/ | HTTP server, database connectors, CLI |
Domain Layer Rules and Models
The domain layer expresses what the system does, not how external technology does it. It contains entities, value objects, and domain services that remain stable across frameworks and delivery channels.
Rules enforce invariants and capture policies so behavior is predictable regardless of interface changes. Keeping this layer pure makes reasoning about the business logic straightforward on GitHub where many contributors collaborate.
Use Case Interactors and Application Services
Use case interactors orchestrate domain objects to accomplish specific goals, such as validating inputs, invoking domain services, and returning outcome objects. Each interactor maps to a clear intent and supports granular testing.
Application services handle cross-cutting concerns like transaction boundaries and authorization without embedding policy. This keeps the GitHub repository modular and focused on coherent features instead of technical plumbing.
Interface Adapters for HTTP, CLI, and Presentation
Interface adapters transform data between the external world and the inner layers. In pirocorpsimplecleanarchitecture, HTTP handlers and CLI commands act as primary entry points that map requests to use cases.
Presenters format responses so that controllers stay thin. This separation allows interface changes, such as adding a new API version or switching from REST to GraphQL, without rewriting core application logic.
Frameworks, Drivers, and Dependency Inversion
The outermost layer includes frameworks, drivers, and configuration that connect the application to databases, message brokers, and third-party APIs. Dependencies point inward toward the domain and use cases to avoid coupling to external details.
On GitHub, this structure clarifies where integration code lives and sets expectations for contributors who add new integrations or replace existing technology stacks.
Organizing Repositories and Onboarding with Clean Architecture
Adopting pirocorpsimplecleanarchitecture on GitHub improves project readability and reduces misinterpretation of responsibilities across contributors. Clear layer boundaries act as navigational signposts in large codebases.
- Define domain models and rules first to establish stable business concepts
- Implement use case interactors that align with GitHub issue workflows
- Add interface adapters incrementally as new entry points are required
- Keep infrastructure configuration explicit and version controlled
- Write tests primarily at the use case and domain layer for reliable regression safety
- Document layer responsibilities in README to speed up contributor onboarding
- Review cross-layer dependencies during code review to preserve inward dependency rule
FAQ
Reader questions
How does pirocorpsimplecleanarchitecture differ from a standard MVC repo on GitHub?
It enforces explicit boundaries so that domain rules never reference frameworks or interface details, whereas MVC often allows controllers and views to leak into business logic.
Can I add a new framework adapter without touching domain code?
Yes, because the domain and use cases rely on interfaces, and new adapters simply implement those interfaces and register dependencies at the outer layer.
What should I keep in the infrastructure folder exactly?
Place database clients, external HTTP clients, message publishers, configuration loaders, and any framework-specific wiring that implements interfaces defined in inner layers.
Is it necessary to have multiple interface adapters in a small project?
Not strictly, but designing for at least one interface adapter early keeps options open for future expansion and improves test isolation for use cases.
