When to choose which

nanostores

Tiny (<1 kB) atomic state shared across frameworks.

Choose it when: Shared state across React/Vue/Svelte/Solid, micro-frontends, or when every byte counts.

  • + Smallest footprint
  • + Cross-framework
  • + Simple
  • - Minimal feature set
  • - Less suited to very large apps

@tanstack/react-query

Async server-state: caching, refetching and mutations.

Choose it when: Managing data from an API — caching, background refetch, pagination, mutations. It complements (not replaces) a client store.

  • + Best-in-class server cache
  • + Great devtools
  • + Handles refetch/stale data
  • - Not for client/UI state
  • - More config than SWR
