component-designing

To avoid primitive obsession in React components, apply self-validating types like branded types or Zod schemas to enforce strongly typed boundaries. This prevents untyped primitives from passing deeply into your component hierarchy and centralizes domain validation.

Feature-based architecture in React organizes code into vertical slices under src/features, colocating related components, hooks, and tests together. Use this structure for scalable TypeScript projects to improve maintainability, discoverability, and prevent architecture drift across UI modules.

Plan a scalable React component hierarchy by defining domain types, separating presentational and container components, and designing custom hooks upfront. Codify these boundaries and feature-based file structures during feature planning or architecture reviews to ensure testability and reuse.

Yes, this React component design approach works for refactoring existing TypeScript projects by applying architecture reviews to untangle component boundaries. It guides migrating code into feature-based vertical slices with colocated tests and clear public exports via feature index files.

Separate presentational and container components in React by extracting business logic into custom hooks, leaving presentational components purely for UI rendering. This pattern improves testability and reuse while maintaining strongly typed boundaries across your feature-based architecture.

The best way to organize tests in a feature-based React architecture is colocating them with feature code inside src/features. This keeps related tests, components, and hooks together, improving discoverability and ensuring tests evolve alongside the feature's public exports.
