React Query is a popular library for managing remote data in React applications. It makes it easy to fetch, cache, and update data from APIs and other remote sources. React Query provides many features that can improve the performance, reliability, and usability of your application.
One of the most powerful features of React Query is its cache. By default, React Query caches the responses from your API calls so that subsequent requests for the same data can be fulfilled from the cache instead of making a new request. This can dramatically improve the performance of your application and reduce the number of requests to your API. You can configure the cache to expire after a certain amount of time or to refresh the cache when data changes on the server.
React Query also provides several hooks that you can use to manage the state of your remote data. The useQuery hook is used to fetch data from an API and return the result to your component. The useMutation hook is used to send data to an API and update the cache with the new data. The useInfiniteQuery hook is used to fetch paginated data and load more pages as needed.
Another great feature of React Query is its support for server-side rendering. React Query provides a way to hydrate the cache on the server and pass the cached data to the client, reducing the time to first render and improving the perceived performance of your application.
Overall, React Query is a powerful and flexible library for managing remote data in your React application. Whether you’re building a simple web app or a complex enterprise system, React Query can help you improve the performance, reliability, and usability of your application.
