SWR (stale-while-revalidate) from Vercel provides a simpler alternative to TanStack Query for remote data fetching. Its mental model is clean: show cached data immediately while revalidating in the background. Confidence is docs-derived.
The API surface covers useSWR for data fetching, useSWRMutation for writes, global config, key-based cache, mutate for cache updates, and optimistic updates. The fetcher function accepts any async function returning data.
SWR is a local library with no platform auth. Data fetching goes through standard fetch or custom fetchers. Authentication headers are part of the fetcher function. No external SWR service credentials.
Operationally, SWR handles deduplication (multiple components requesting the same key get one request), revalidation on focus/reconnect, and error retry automatically. The cache key design maps naturally to REST endpoints.
Documentation at swr.vercel.app is clear and concise. Developer experience is strong; SWR has a smaller API surface than TanStack Query, making it faster to adopt for teams that do not need advanced features like infinite scroll or complex cache manipulation.
