TanStack Router

Use this skill to apply current, source-backed TanStack guidance. Keep answers aligned with installed package source first, official TanStack docs second, and package-shipped skills third. Read references/current-authority.md when APIs, versions, CLI commands, or source freshness materially affect the task.

Decision Tree

• Need a new route? Use file-based routing and let the plugin/CLI generate routeTree.gen.ts.
• Need shared dependencies? Type them in createRootRouteWithContext<T>() and pass them to createRouter({ context }).
• Need URL state? Validate with validateSearch and use loaderDeps for cache keys.
• Need route data? Use loaders; use TanStack Query only when Query owns server-state cache.
• Need route splitting? Prefer router plugin autoCodeSplitting: true; use .lazy.tsx as fallback.
