SWR is React Hooks library for data fetching.
The name “SWR” is derived from stale-while-revalidate, a HTTP cache invalidation strategy popularized by HTTP RFC 5861. SWR is a strategy to first return the data from cache (stale), then send the fetch request (revalidate), and finally come with the up-to-date data.
With SWR, components will get a stream of data updates constantly and automatically.
And the UI will be always fast and reactive.
