react-router-v7-patterns

Fix React Router v7 nested route tab highlight bugs by implementing URL-driven tab state patterns. This synchronizes the active tab UI state directly with the URL parameters, ensuring the page displays the correct component when the URL changes.

React Router v7 redirects drop query string parameters when not explicitly preserved. Use query string preservation patterns during backward-compatible redirects to carry over existing search params and prevent broken deep links.

Refactor top-level React routes into a nested tabbed settings layout by applying layout chrome ownership patterns. This prevents duplicate layout headers and ensures the parent route renders the shell while child sub-routes render the tab content.

Stale component state from route reuse in React Router v7 data routers is caused by component reuse race conditions. Apply search param synchronization patterns to force proper state resets when navigating between nested sub-routes.

Use Navigate redirects versus re-pointing links for React Router v7 backward compatibility based on decision tree signals. Choose Navigate when you need to sunset old paths entirely, and re-point links when consolidating routes into a nested sub-route tree.

These nested route patterns work with both React Router v7 and v6.4+ data routers. The implementation patterns for tabbed layouts, query string preservation, and search param synchronization apply across both versions to eliminate SPA refactoring bugs.
