Declarative Fetching Libraries
summary
Compares three libraries by behavior not buzzwords: Apollo is GraphQL-only and does normalized caching so a mutation updates that record everywhere; SWR is tiny (SWR ~11KB) and agnostic—simple fetcher, stale-while-revalidate and focus-based revalidation built in; TanStack/React Query is the heaviest, most full-featured, supports REST/GraphQL, persistent cache, polling, infinite queries, devtools and render-batching/selectors that skip re-renders when unused fields change. Practical takeaway: pick Apollo for GraphQL normalization, TanStack for power, SWR for minimalism.
