What problem does it solve?
TanStack Router removes the complexity and fragility of managing route definitions, navigation state, and data fetching across React and Solid single-page applications by providing a unified, type-safe routing system that prevents mismatched params, unvalidated search state, and ad-hoc data loading patterns.
Core Features & Use Cases
- Type-safe route trees and params: Strong TypeScript inference for route params, search schemas, loader data, and route context to eliminate runtime mismatches.
- First-class search params and validation: Declarative search param schemas and helpers for reading and updating query state robustly.
- Route-level data loading and caching: Built-in loaders, loaderDeps, deferred loading, and integration points with TanStack Query for consistent cache behavior and code splitting.
- Use Case: Build a blog or dashboard where the posts list is loaded and cached at the route level, pagination and filters are validated as search params, and each post details page uses a dynamic param with guarded access and lazy-loaded UI.
Quick Start
Generate a file-based TanStack Router setup for a React app with a root layout, a posts list route that validates search params and uses a loader, and a dynamic post details route protected by a beforeLoad authentication check.
