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)
