## What it is
TanStack Router is a fully type-safe, client-first router for React and Solid applications, with file-based routing, nested layouts, loaders with caching, and validated search-param state management. It also powers TanStack Start, a full-stack framework adding SSR, streaming, and type-safe server functions.

## Use cases
- build a type-safe SPA router for React
- manage filters and pagination in URL search params with validation
- add nested layouts and error boundaries to a React app
- prefetch route data before navigation
- build a full-stack SSR app with server functions
- migrate from React Router for better type inference

## When to choose
- you use TypeScript and want end-to-end type safety for routes, params, and search state
- you want file-based routing with generated route trees
- you need loaders with built-in SWR caching and prefetching
- you want URL state treated as a validated, shareable state manager
- you're building a full-stack React or Solid app with TanStack Start

## When to avoid
- you're on a framework with its own built-in router (Next.js, SvelteKit)
- you don't use TypeScript and can't benefit from its core value proposition
- you need a router for frameworks other than React or Solid
- you want a minimal zero-config router without a build plugin or CLI
