Type safety in TanStack Router is enforced through end-to-end type inference, allowing params, search params, loader data, and route context to flow without manual casts. A single Register declaration unifies the route tree for strict validation.

TanStack Router supports SSR through dehydration and hydration hooks, ensuring compatibility with TanStack Start. This enables safe server rendering and client hydration while maintaining type-safe route definitions and context.

You handle notFound behavior and errors by applying production-grade routing patterns within your route tree. TanStack Router provides mechanisms for beforeLoad, loaders, and clear error handling boundaries to manage missing routes robustly.

TanStack Router provides a framework-agnostic core that unifies route trees, loaders, and context across React, Solid, and SSR. You use createRouter and createRoute to build consistent definitions regardless of the rendering framework.

The best way to implement code-splitting is by combining route masking with production-grade routing patterns. TanStack Router provides guidance for splitting strategies alongside beforeLoad and loader lifecycles to optimize bundles safely.

You define per-route context using createRootRoute and createRoute, allowing shared context and registration to flow through the route tree. This ensures type-safe composition and strict validation for each route's specific requirements.
