Hydrating the QueryClient with server-side pre-fetched data is a strategy that can be used to improve the performance of your application and reduce the load on your API. This technique can be particularly useful in scenarios where you are using server-side rendering, have frequently changing data, or are using optimistic updates.
When using server-side rendering (SSR), hydrating the QueryClient with server-side pre-fetched data is essential. This strategy can help improve the performance of your application and reduce the number of requests to your API. By reusing the pre-fetched data on the client-side, you can avoid making additional requests to the API, which improves the perceived performance of your application. With this technique, you can ensure that your application is faster and more responsive, giving your users a better experience.
If you have frequently changing data that needs to be fetched on every request, hydrating the QueryClient with server-side pre-fetched data can help ensure that the data is up-to-date and accurate. By pre-fetching the data on the server-side, you can avoid the latency of making requests to the API on the client-side. This technique can help improve the reliability of your application and reduce the likelihood of errors occurring due to stale data (Outdated data).
When using optimistic updates, hydrating the QueryClient with server-side pre-fetched data can be extremely useful. This strategy can help ensure that the updated data is available immediately after the update. This can reduce the likelihood of inconsistencies or flickering in your application, which can be disruptive to the user experience.
Overall, hydrating the QueryClient with server-side pre-fetched data is a powerful tool that can help improve the performance and reliability of your application while reducing the load on your API. By taking advantage of this feature provided by React Query and Next.js, you can ensure that your application is fast, responsive, and reliable, giving your users the best possible experience.
