What is tanstack-fetch?
tanstack-fetch (by Mohammad Garmabi) is a tiny, typed Fetch client shaped for @tanstack/react-query.
It is not an official TanStack package — it matches the same mental model Query expects from a queryFn:
- Return data on success
- Throw on HTTP failure (
FetchError) - Honor
AbortSignalso cancel / unmount is clean
Who it’s for
- Apps already on TanStack Query that want a smaller alternative to axios / ky
- Next.js / TanStack Start apps that need SSR cookie forwarding
- Teams that want SSE with
Authorization(notEventSource) - tRPC users who want one shared auth/plugin client
