react-router-framework-mode

React Router loaders and actions handle full-stack data fetching by coordinating server-side data loading with mutations. You configure loader and clientLoader functions to fetch data, and action or clientAction functions to process form mutations across SSR and SPA deployments.

React Router framework mode is a built-in routing configuration that manages server-side rendering, static pre-rendering, and SPA deployments. You need it when building full-stack React applications that require coordinated data loading, mutations, and navigation across different rendering strategies.

Type-safe routing in React Router framework mode is set up using a file-based routing structure. You define routes with loader and action exports, then use Link and NavLink components for navigation to ensure type-safe data passing and UI state management.

Yes, React Router framework mode supports both server-rendered and client-side data handling. You can implement server logic using loader and action exports, while clientLoader and clientAction handle client-side fetching and mutations for SPA and pre-rendered deployments.

Redirects and authentication flows in React Router framework mode are handled within loader and action functions. You validate user sessions during the data loading phase and return redirect responses to protect routes and manage navigation for authenticated users.

Yes, React Router framework mode supports pending and optimistic UI states. By using the Form component for mutations, you can track submission states to render pending UI and apply optimistic updates while the action processes the data request.
