An example of an AI chatbot conversation about React Query invalidation and its functionality.
What is React Query invalidation and how does it work?
React Query invalidation is a mechanism to refetch data when it becomes stale or when certain actions occur. It ensures that your UI displays the most up-to-date information.
Can you give me an example of when I would need to invalidate a query?
Sure! If you have a list of users and you add a new user, you would want to invalidate the user list query to fetch the updated list.
How do I invalidate a query in React Query?
You can invalidate a query using the queryClient.invalidateQueries('queryKey') method, where 'queryKey' is the key of the query you want to refetch.
Is there a way to automatically invalidate queries after a mutation?
Yes! You can use the onSuccess callback in your mutation to call invalidateQueries for any related queries.
