dehydrateQuery

ts
function dehydrateQuery(
   query, 
   serializeData?, 
   shouldRedactErrors?): DehydratedQuery;

Defined in: packages/query-core/src/hydration.ts:148

Dehydrates a single Query into a serializable DehydratedQuery snapshot. Note that most query config (e.g. queryFn, staleTime) is not dehydrated but instead meant to be configured again when consuming the de/rehydrated data, typically with useQuery on the client. If the query is still pending, its in-flight promise is dehydrated too so it can be resumed on the other side instead of re-fetched.

Parameters

query

Query

The query to dehydrate.

serializeData?

TransformerFn

Optional transform applied to query.state.data before it is included in the snapshot.

shouldRedactErrors?

(error) => boolean

Optional predicate; if it returns false for the promise's rejection error, that error is kept as-is instead of being redacted.

Returns

DehydratedQuery
