React Router's loader and action APIs eliminate render-then-fetch waterfalls by loading data before routes render. Here's how to implement the smallest viable design with proper error handling and verification steps.
React Router's loader and action APIs fetch data before rendering and automatically revalidate after mutations, removing manual useEffect fetching and cache invalidation.
Decide between React Router’s data router API and classic component routing. Compare loaders, actions, error handling, and parallel fetches. See a concrete implementation and how to validate the choice.

Learn how to use React.lazy and Suspense with React Router v6 to split your JavaScript bundles, reducing initial load times and improving TTI.
Learn how React Router v6’s loader and action APIs centralize data fetching and mutations, eliminate race conditions, and simplify optimistic UI with a concrete todo‑list example.
Learn how to use URL parameters, useParams, and nested routes with Outlet in React Router to build scalable resource-based navigation.
Stop the 'back button loop' in React apps. Learn how to use useNavigate with the replace option to manage history stacks and handle relative paths in nested routes.
Use React Router data routers with route-level loaders and actions to fetch before render, avoid render waterfalls, and handle mutations declaratively with revalidation.
