If you use TanStack Query, your queryFn wants: return data, throw on error, honor AbortSignal.

tanstack-fetch 1.7.0 ships real adapters for Solid, Angular, and Svelte (parity with React/Vue), a doctor CLI, more migrate scaffolds, onDownloadProgress, and docs that filter by framework.

Not an official TanStack package — shaped for the same Query API.

Upgrade 

npm install tanstack-fetch@1.7.0

Adapters 

import { useSse } from 'tanstack-fetch/solid' // or tanstack-fetch/svelte · tanstack-fetch/angular
Import API
tanstack-fetch/solid FetchProvider, useFetch, useSse
tanstack-fetch/svelte setFetchClient, useFetch, useSse
tanstack-fetch/angular provideFetchClient, injectFetch, useSse

Doctor + migrate 

npx tanstack-fetch doctor --dir ./src npx tanstack-fetch migrate --from axios --framework solid --write npx tanstack-fetch migrate --from fetch --framework sveltekit --write

Download progress 

await api.get('/files/report.pdf', { parseAs: 'blob', onDownloadProgress: ({ progress, loaded, total }) => console.log(progress, loaded, total), })
