React Query Tutorial in Hindi #6 React Query Stale Time

Показать описание

React Query's staleTime is an important configuration option that allows you to control how long the data in the query cache is considered "stale" before it's considered eligible for refetching. It defines the time, in milliseconds, after which a query's data is considered stale.

When you use staleTime, React Query will allow you to display stale data from the cache even after the initial fetch, until the staleTime duration has passed. This means that during this period, your application can display data from the cache immediately without waiting for a network request to complete, providing a faster and more responsive user experience.

If a component using a query with a stale data is re-rendered within the staleTime window, React Query will still show the stale data while initiating a background refetch. If the refetch is successful, the component will be updated with the latest data. This helps to ensure that your UI remains up to date while maintaining a responsive user experience.Please do like share and comment if you like the video please do hit like and if you have any query please write it comment box
