2. Benefits of Using SWR
The name SWR stands for Stale-While-Revalidate, a strategy popular in HTTP RFC 5861. But what does that mean really? It means your app will render data (stale), then fetch the new data (revalidate) in the background. Lastly, it will come up with new data.
This strategy yields several benefits, such as fast rendering, real-time updates, and automatic retries.
Fast Rendering and Real-time Updates
SWR enables your app to render immediately with cached (stale) data, and then revalidate and update with fresh data in the background. This means your users get to see data instantly, enhancing their…
