What are the differences between React Query and other data-fetching libraries?

What are the main differences between React Query and libraries like Axios or Redux?

React Query is primarily focused on server state management, while Axios is a promise-based HTTP client for making requests. Redux is more about managing global state, which can include both client and server state. React Query simplifies data fetching and caching, making it easier to work with server data.

Can you explain how React Query handles caching compared to Redux?

React Query automatically caches data based on the query key and provides built-in mechanisms for invalidation and refetching. In contrast, Redux requires manual management of the state and caching logic, which can be more complex.

Is React Query suitable for all types of applications?

While React Query excels in applications that require frequent data fetching and synchronization with a server, it may not be necessary for simpler applications that don't rely heavily on server data.

What are some advantages of using React Query over traditional state management?

React Query offers automatic caching, background data synchronization, and built-in support for pagination and optimistic updates, which can significantly reduce the amount of boilerplate code compared to traditional state management solutions.
