1. What are the main benefits of using RTK Query for data fetching?
Difficulty: EasyType: SubjectiveTopic: RTK Query
RTK Query eliminates the need to write data fetching logic manually by providing automatic caching, request deduplication, loading and error states, and auto-generated hooks that handle all async complexity for you. It dramatically reduces boilerplate by removing the need for thunks, actions, and reducers for every API call, while providing powerful features like automatic refetching, optimistic updates, polling, and cache invalidation with tags. The declarative approach makes code more maintainable, the built-in caching improves performance by avoiding redundant requests, and the TypeScript support provides excellent type safety for API interactions.
