## Type Parameters
|
||||
|
||||
### TQueryFnData
|
||||
|
||||
`TQueryFnData` = `unknown`
|
||||
|
||||
### TError
|
||||
|
||||
`TError` = [`DefaultError`](../type-aliases/DefaultError.md)
|
||||
|
||||
### TData
|
||||
|
||||
`TData` = `TQueryFnData`
|
||||
|
||||
### TQueryKey
|
||||
|
||||
`TQueryKey` *extends* [`QueryKey`](../type-aliases/QueryKey.md) = [`QueryKey`](../type-aliases/QueryKey.md)
|
||||
|
||||
### TPageParam
|
||||
|
||||
`TPageParam` = `never`
|
||||
|
||||
## Properties
|
||||
|
||||
### ~~gcTime?~~
|
||||
|
||||
```ts
|
||||
optional gcTime: number;
|
||||
```
|
||||
|
||||
Defined in: [packages/query-core/src/types.ts:277](https://github.com/TanStack/query/blob/main/packages/query-core/src/types.ts#L277)
|
||||
|
||||
The time in milliseconds that unused/inactive cache data remains in memory.
|
||||
When a query's cache becomes unused or inactive, that cache data will be garbage collected after this duration.
|
||||
When different garbage collection times are specified, the longest one will be used.
|
||||
Setting it to `Infinity` will disable garbage collection.
|
||||
|
||||
Defaults to `5 * 60 * 1000` (5 minutes), or `Infinity` during SSR.
|
||||
|
||||
Note: the maximum allowed time is about 24 days, imposed by `setTimeout`'s 32-bit signed integer delay — see
|
||||
`timeoutManager.setTimeoutProvider` for a workaround.
|
||||
|
||||
#### Inherited from
|
||||

||||

|
||||

### ~~initialData?~~
|
||||
|
||||

||||
optional initialData:
|
||||

Defined in: [packages/query-core/src/types.ts:317](https://github.com/TanStack/query/blob/main/packages/query-core/src/types.ts#L317)
|
||||
|
||||
If set, this value will be used as the initial data for the query cache (as long as the query hasn't been
|
||||
created or cached yet).
|
||||
If set to a function, the function will be called **once** during the shared/root query initialization, and be
|
||||
expected to synchronously return the initial data.
|
||||
Initial data is considered stale by default unless a `staleTime` has been set.
|
||||
`initialData` **is persisted** to the cache.

|
||||
|
||||
This option can be used to persist the result of a query to an external storage, bypassing the need to actually
|
||||
call the `queryFn`. Useful for persisting a query's data across e.g. server/client boundaries.
|
||||
|
||||

|
||||
`queryClient.setDefaultOptions`.
|
||||
Receives a [QueryFunctionContext](../type-aliases/QueryFunctionContext.md).
|
||||
Must return a promise that will either resolve data or throw an error. The data cannot be `undefined`.
|
||||
|
||||
#### Inherited from

|
||||
WithRequired.queryFn

|
||||
|
||||
The query key to use for this query.
|
||||
|
||||
The query key will be hashed into a stable hash. See [Query Keys](https://tanstack.com/query/latest/docs/framework/react/guides/query-keys)
|
||||
for more information.
|
||||
|
||||

|
||||
|
||||
If `false`, failed queries will not retry by default.
|
||||
If `true`, failed queries will retry infinitely.
|
||||
If set to an integer number, e.g. 3, failed queries will retry until the failed query count meets that number.
|
||||
If set to a function `(failureCount, error) => boolean` failed queries will retry until the function returns false.
|
||||
|
||||
Defaults to `3` on the client and `0` on the server.

|
||||
|
||||
This function receives a `retryAttempt` integer and the actual Error and returns the delay to apply before the
|
||||
next attempt in milliseconds.
|
||||
|
||||
A function like `attempt => Math.min(attempt > 1 ? 2 ** attempt * 1000 : 1000, 30 * 1000)` applies exponential
|
||||
backoff.
|
||||
|
||||
A function like `attempt => attempt * 1000` applies linear backoff.
|
||||
|
||||
Defaults to a function that applies exponential backoff, capped at 30 seconds.
|
||||
|
||||
#### Inherited from
|
||||

|
||||
|
||||
Set this to `false` to disable structural sharing between query results.
|
||||
Set this to a function which accepts the old and new data and returns resolved data of the same type to implement custom structural sharing logic.
|
||||
|
||||
Defaults to `true`.
