What are the differences between SWR and other caching strategies?

What are the differences between SWR and other caching strategies?

SWR (stale-while-revalidate) is a caching strategy that allows you to fetch data in the background while serving stale data. This contrasts with strategies like cache-first or network-first, which prioritize either cached data or fresh data.

Can you explain how SWR improves user experience?

SWR enhances user experience by providing instant feedback with stale data while ensuring that the latest data is fetched in the background, reducing loading times and perceived latency.

What are some use cases where SWR is preferred?

SWR is ideal for applications with frequently changing data, like dashboards or social media feeds, where users benefit from seeing the most recent updates without waiting.

How does SWR compare to React Query?

Both SWR and React Query offer similar functionalities, but SWR is more lightweight and focuses on simplicity, while React Query provides more features like caching and pagination out of the box.

Are there any downsides to using SWR?

One downside is that SWR may not be suitable for all scenarios, especially where data consistency is critical, as it serves stale data before fetching fresh data.
