Redux toolkit query is for data and caching in a web application. It is an optional add-on in the Redux toolkit package.

RTK Query offers a set of powerful features that help developers handle common tasks related to data fetching, caching, and synchronization with the server. Some key features of RTK Query include:

  • Automatic API request generation: RTK Query generates API request endpoints based on a configuration object that defines the URL, method, headers, and other options. It eliminates the need to write boilerplate code for making API requests.

  • Automatic caching and invalidation: RTK Query automatically caches API responses, allowing subsequent requests for the same data to be served from the cache. It also provides mechanisms for cache invalidation when the data on the server changes.

  • Data synchronization: RTK Query handles data synchronization between the client and server, ensuring that the local data remains up-to-date with the server data. It supports background data fetching and real-time updates through WebSockets.

    Advanced data manipulation and normalization: RTK Query provides built-in support for data manipulation and normalization, allowing you to transform and shape the API responses before storing them in the cache.

  • Integration with Redux: RTK Query seamlessly integrates with Redux, leveraging the Redux store for storing the cached data and managing the state of ongoing API requests. It works well alongside other Redux Toolkit features, such as the Redux store, reducers, and middleware.

Overall, RTK Query aims to simplify the process of managing remote data in a Redux-based application by providing a standardized and efficient way to handle data fetching, caching, and synchronization.

You can learn more about RTK Query and its usage in the official documentation: RTK Query
