SWRConfig

SWRConfig is a configuration object used in the SWR (Stale-While-Revalidate) library, which is a React Hooks library for data fetching. SWRConfig allows developers to set global configurations for SWR, such as default cache settings, revalidation strategies, and error handling. By using SWRConfig, developers can ensure consistent behavior across their application, reducing the need for repetitive code and improving maintainability.

The SWRConfig object can be passed as a prop to the SWRConfig component, which wraps the part of the application where the configuration should apply. This allows for scoped configurations, enabling different parts of the application to have different SWR settings if necessary.

Key properties that can be set in SWRConfig include:

- provider: A custom provider for managing the cache.

- revalidateOnFocus: A boolean indicating whether to revalidate data when the window regains focus.

- revalidateOnReconnect: A boolean indicating whether to revalidate data when the network reconnects.

- errorRetryCount: The number of times to retry fetching data in case of an error.

- errorRetryInterval: The interval between retries in case of an error.

By leveraging SWRConfig, developers can streamline their data fetching logic, enhance performance, and improve the overall user experience by ensuring that data is always up-to-date and reliable.
