To separate business logic from rendering in React components, apply a four-layer pattern using dedicated files for controller, presenter, feature, and view to decouple data handling, state management, and presentation for better testability.

The best way to scaffold a new React feature with clean architecture is to create four colocated files (controller.ts, presenter.ts, feature.tsx, and view.tsx) and wire them in a client component using a view contract.

Manage multiple UI states like loading, empty, and error in React by using a contract-driven view with renderAs, display, instructions, and effects, isolating state presentation from data fetching and business logic layers.

No, this UI architecture pattern requires no external dependencies, but it requires a React-based project environment and dedicated files for each architectural layer to enforce the client boundary and view contracts.

Use a four-layer architecture for frontend UI development to isolate data fetching, state management, and rendering, which streamlines testability and maintainability by enforcing strict separation of concerns across layers.
