react-feature-sliced-design

Organize React and TypeScript code using Feature-Sliced Design to establish strict import rules. It enforces a layered architecture with downward-only imports to prevent circular dependencies and improve modularity.

The best way to structure a large scale React frontend is using Feature-Sliced Design. It separates code into six layers—app, pages, widgets, features, entities, and shared—to ensure clear boundaries and maintainability.

In React feature-sliced design, place new user interactions in the features layer. Components and hooks are organized within specific slices, each containing internal directories like ui, model, api, and lib for consistent code placement.

Yes, feature-sliced design works with existing TypeScript workflows. It guides component, hook, and API placement within slices without requiring external dependencies, integrating directly into your current React development process.

Same-layer imports are forbidden in feature-sliced design to maintain strict modularity. This architectural constraint prevents tightly coupled code across features and widgets, ensuring slices remain independent and maintainable.
