react-clean-architecture

Structure React Native Expo projects by enforcing strict separation between Core domain logic, Infrastructure adapters, and UI layers. This clean architecture approach applies ports/adapters, use cases, and the Result pattern to scale features while maintaining clear boundaries for maintainability and testability.

The ports and adapters pattern in React Native separates core domain entities from external infrastructure using defined interfaces and adapter implementations. It isolates business logic from UI and integration points, creating immutable boundaries to improve testability and feature scaling.

Yes, clean architecture applies directly to Expo apps built with TypeScript and Bun. It enforces strict Core, Infrastructure, and UI layer separation, utilizing ViewModels and Atomic Design components to structure modules while maintaining immutable architectural boundaries.

Handle errors in React Native clean architecture by implementing the Result pattern. This approach returns explicit success or failure outcomes from use cases instead of throwing exceptions, maintaining immutable boundaries between the domain core and infrastructure adapters.

Use ViewModels and Atomic Design in React Native clean architecture when structuring the UI layer. ViewModels manage presentation logic and state, while Atomic Design components provide reusable UI elements that respect strict separation from underlying domain and infrastructure layers.

Applying clean architecture to React Native requires a clearly defined core with entities, ports, corresponding adapters, and UI modules with ViewModels. This strict layer separation introduces boilerplate and architectural overhead, which may be excessive for very small or simple prototype applications.
