Redux Toolkit Query
Redux Toolkit Query (RTK Query) is a powerful data fetching and caching library built into Redux Toolkit, designed to simplify server state management in React applications. It provides automatic caching, background refetching, and optimistic updates for API calls, eliminating the need to write manual data fetching logic. It integrates seamlessly with Redux state management, offering a declarative approach to handling asynchronous data.
Developers should use RTK Query when building React applications that require efficient data fetching from APIs, especially in scenarios with complex caching needs, such as dashboards, e-commerce sites, or real-time data displays. It reduces boilerplate code, improves performance through intelligent caching, and simplifies state synchronization between server and client, making it ideal for modern web apps with frequent API interactions.
