React Router
The skill is based on React Router v7.13.0, generated at 2026-01-31.
React Router is a multi-strategy router for React bridging the gap from React 18 to React 19. You can use it maximally as a React framework or as minimally as you want. It supports three modes: Declarative (basic routing), Data (with loaders/actions), and Framework (full-featured with type safety and code splitting).

Key Recommendations
- Choose the right mode: Use Framework mode for new projects, Data mode if you need control over bundling, Declarative mode for simple routing
- Use Route Module API in Framework mode for automatic code splitting and type safety
- Return promises from loaders for streaming with Suspense
- Use fetchers for non-navigating form submissions and concurrent data loading
- Export ErrorBoundary in route modules to catch errors gracefully
- Use middleware for cross-cutting concerns like authentication and logging
- Leverage type safety in Framework mode with generated Route types
- Prefer declarative navigation (Link, NavLink, Form) over imperative (useNavigate)
