How do SWR and React Query compare in terms of performance?

How do SWR and React Query compare in terms of performance?

Both SWR and React Query are popular libraries for data fetching in React, but they have different performance characteristics. SWR is designed for simplicity and focuses on caching and revalidation, while React Query offers more features like pagination and query invalidation, which can impact performance depending on your use case.

Can you explain how caching works in both libraries?

Sure! In SWR, caching is handled automatically, and it uses a stale-while-revalidate strategy, meaning it serves cached data while fetching new data in the background. React Query also has a robust caching mechanism, allowing you to configure cache time and stale time, giving you more control over when data is considered fresh.

Which one is better for large-scale applications?

For large-scale applications, React Query might be more suitable due to its extensive features like query batching, pagination, and more granular control over caching. However, SWR can still be effective if your application requires simpler data fetching.

Are there any benchmarks comparing their performance?

Yes, there are several benchmarks available online that compare the performance of SWR and React Query. Generally, the performance can vary based on the specific use case, so it's best to test both in your application context.
