TanStack Router
Fully type-safe React router with first-class search parameter support. TanStack Router generates TypeScript types for all routes, parameters, and search params, making route navigation fully type-checked — typos in route names are compile errors. Supports file-based routing (like Next.js) and programmatic route definitions. Key differentiator: search parameters are treated as first-class state (typed, validated, serialized) rather than strings.

⚙ Agent Friendliness
🔒 Security
Client-side routing — no server-side attack surface. Route guards via beforeLoad prevent unauthorized navigation. MIT licensed.
⚡ Reliability
Best When
You want fully type-safe React routing with powerful search param management and are starting a new project or willing to refactor routing.
Avoid When
You're using Next.js (has its own router), need SSR, or have a large React Router codebase where migration cost is high.
Use Cases
- • Build React applications with fully type-safe navigation where incorrect route paths and missing parameters are TypeScript compile errors
- • Implement complex URL state management using TanStack Router's typed search params with Zod validation and serialization
- • Create React SPA routing with file-based routes that co-locate loaders, error boundaries, and pending UI per route
- • Migrate from React Router v5/v6 to get type-safe routes and improved search param handling
- • Build admin dashboards or data-heavy applications where search params encode filter/sort/pagination state with full type safety
Not For
- • Non-React frameworks — TanStack Router is React-only (Vue, Solid, and Angular support are planned)
- • Server-side rendering at scale — use Next.js or Remix for full SSR capabilities with React
- • Simple single-page apps with 2-3 routes — overhead not justified for trivial routing needs
Interface
Authentication
Local library — no authentication. Route guards for auth-protected routes implemented via beforeLoad hooks.
Pricing
TanStack Router is MIT open source from Tanner Linsley (creator of TanStack Query). Free for personal and commercial use.
Agent Metadata
Known Gotchas
- ⚠ TanStack Router requires code generation for file-based routing — running the TanStack Router devtools plugin or 'tsr generate' CLI creates the routeTree.gen.ts file; missing this file causes type errors
- ⚠ Route types are generated — after adding new route files, regenerate routeTree.gen.ts before TypeScript types are available for the new routes
- ⚠ Search params require explicit schema definition using Zod or validateSearch function — undefined search params are typed as unknown without schema validation
- ⚠ Router context (context object) for injecting dependencies (auth, API clients) must be typed and provided at router creation — missing context causes type errors at usage sites
- ⚠ TanStack Router v1.x has a different API from the beta/v0 versions — older blog posts and tutorials may use the outdated API
- ⚠ Data loading uses loaders per route — unlike React Query which is component-level, TanStack Router loaders are route-level and block route transitions; combine with TanStack Query for component-level caching
