Only throw error if there is no data in the cache
Hi everyone, I'm configuring react-query with
throwOnError option set to true but I only want the error to be throw when there's no data in the cache. Is there any way to achieve that with react-query ?3 Replies

throwOnError: (error, query) => typeof query.state.data === 'undefined'optimistic-goldOP•2y ago
work like a charm, thank you.
One more question, is it possible to check if there is previous data in the cache, for example a cache with key
['list', {page: 1}] before throwing an error for a query with ['list', {page: 2}] key? My best ideal is to use what you suggested along with placeholderData: keepPreviousData option for certain queries, just not sure if this is the correct approachdeep-jade•2y ago
you can take the provided
query.queryKey and do fuzzy matching against ['list'] by importing the matchQuery function
