What’s new in React Query 3

React Query is a third-party library designed to address the limitations of React in handling server state management, particularly for asynchronous data fetching and caching. By providing custom hooks, React Query simplifies the process of fetching, caching, and updating server state, offering a more efficient and maintainable alternative to traditional patterns that rely on useEffect and useState. Unlike Apollo Client, React Query supports both REST and GraphQL, and it offers features such as in-memory caching, background state updates, and the ability to retry or persist mutations. Version 3 of React Query introduces enhancements like query and mutation selectors, the useQueries hook for fetching multiple queries, and the useIsFetching hook to monitor ongoing data fetches. These features collectively enhance the developer experience by reducing boilerplate code, avoiding prop drilling, and improving application performance through efficient server state handling.
