React Hooks for Data Fetching
About Vercel Swr
From the project's README at github.com/vercel/swr. Lightly cleaned for readability; for the full source see the upstream repo.
The name “SWR” is derived from , a cache invalidation strategy popularized by HTTP RFC 5861. SWR first returns the data from cache (stale), then sends the request (revalidate), and finally comes with the up-to-date data again.
With just one hook, you can significantly simplify the data fetching logic in your project. And it also covered in all aspects of speed, correctness, and stability to help you build better experiences: Fast, lightweight and reusable data fetching Transport and protocol agnostic Built-in cache and request deduplication Real-time experience Revalidation on focus Rev
