10. How do you refetch data manually in RTK Query?
Manually Refetching Data in RTK Query
RTK Query automatically handles caching and background refetching, but it also allows you to manually trigger a refetch when needed. This is useful when data changes outside the app or after performing a mutation.
Ways to Manually Refetch Data
- Using the
refetchmethod – Each query hook returns arefetchfunction that can be called to trigger a new request.
- Using the
- Using
useLazyQuery– Allows you to fetch data only when you explicitly trigger it.
- Using
- Invalidating cache tags – If using cache tags, mutations can invalidate queries, causing them to refetch automatically.
Example 1: Using the `refetch` Method
Example 2: Using `useLazyQuery` for Manual Fetching
Manual refetching gives developers fine-grained control over when data should be refreshed — ideal for pull-to-refresh, retry buttons, or after performing specific actions.
