TanStack Router provides fully type-safe routing for React with search params validation, loaders, and the best TypeScript integration of any router.
Reviewer scorecard
“The simplest way to get typed, validated outputs from LLMs. Pydantic integration is natural for Python developers.”
“Type-safe search params and route params are game-changing. Catch route errors at compile time, not runtime.”
“Does one thing perfectly. No over-abstraction, just structured outputs. The anti-LangChain.”
“The type safety for search params alone justifies adoption. URL state management done right.”
“Structured outputs are the bridge between LLMs and traditional software. Instructor makes that bridge trivial to build.”
“TanStack Router plus TanStack Start could become a serious full-stack framework contender.”
