tanstack-router-v1

TanStack Router v1 file-based routing uses createFileRoute within files like posts.$id.tsx. You define loaders and components directly, then register the generated routeTree in your router setup to enable type-safe navigation and data preloading.

TanStack Router handles data loading and access control using loader, beforeLoad, notFound, and redirect patterns. These mechanisms allow you to preload route data, enforce authentication guards, and manage notFound errors before the route component renders.

Type safety for search params and path variables is ensured by using validateSearch and parseParams within your route definitions. Combined with TypeScript registration, this provides fully typed useSearch and useParams hooks for your React components.

TanStack Router v1 supports SSR and head management through the head() function. It handles SSR module loading effects and addresses head() ordering pitfalls to ensure proper meta tag rendering during server-side rendering.

Code-splitting and preload strategies in TanStack Router include automatic and manual code splitting techniques. These preload strategies optimize performance by loading route modules and data efficiently before navigation completes.

Head() metadata rendering in the wrong order during SSR is a known pitfall caused by SSR module loading effects in TanStack Router v1. Properly structuring your head() implementation and understanding the module loading sequence resolves this ordering issue.
