When to choose which
effector
Reactive logic from events, stores and effects.
Choose it when: Complex reactive business logic you want strongly typed and framework-agnostic, decoupled from the view.
- + Powerful reactive primitives
- + Excellent TypeScript
- + Framework-agnostic
- - Smaller community
- - New vocabulary to learn
@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
