What is this?
TanStack Router is a modern router for the web built around end-to-end type safety — routes, params, loaders and search params are all checked. The repo also hosts TanStack Start, a full-stack framework built on top of the router.

The repo itself is a pnpm + nx monorepo.

Check the docs for the current list of supported frameworks.

TanStack Start is opt-in: add it when you want full-document SSR, streaming and server functions on the same routing model.
