React Query is a popular open-source library for managing and caching asynchronous data in React applications. It simplifies the process of fetching, caching, and updating data from various sources, such as APIs or databases, and provides a unified and declarative API for handling data in a React application.
React Query offers several features, including:
- Automatic caching and invalidation of data
- Request deduplication and cancellation
- Automatic retries and error handling
- Pagination and infinite scrolling support
- Suspense and concurrent mode support
React Query is designed to work well with various data fetching libraries, such as Axios, Fetch, and GraphQL clients, and it also supports server-side rendering and integration with React Native.
Overall, React Query helps developers to write more efficient and scalable applications by simplifying the data management process and reducing the amount of boilerplate code needed to handle asynchronous data.
