This utility comes as a separate package and is available under the '@tanstack/query-async-storage-persister'
import.
npm install @tanstack/query-async-storage-persister @tanstack/react-query-persist-client

yarn add @tanstack/query-async-storage-persister @tanstack/react-query-persist-client
createAsyncStoragePersister
functionstorage
to it that adheres to the AsyncStorage
interface - the example below uses the async-storage from React NativePersistQueryClientProvider
component.import AsyncStorage from '@react-native-async-storage/async-storage'import { QueryClient } from '@tanstack/react-query'import { PersistQueryClientProvider } from '@tanstack/react-query-persist-client'import { createAsyncStoragePersister } from '@tanstack/query-async-storage-persister'
const queryClient = new QueryClient({ defaultOptions: { queries: { cacheTime: 1000 * 60 * 60 * 24, // 24 hours }, },})
const asyncStoragePersister = createAsyncStoragePersister({ storage: AsyncStorage,})
const Root = () => ( <PersistQueryClientProvider client={queryClient} persistOptions={{ persister: asyncStoragePersister }} > <App /> </PersistQueryClientProvider>)
export default Root
Retries work the same as for a SyncStoragePersister, except that they can also be asynchronous. You can also use all the predefined retry handlers.
createAsyncStoragePersister
Call this function to create an asyncStoragePersister that you can use later with persistQueryClient
.
createAsyncStoragePersister(options: CreateAsyncStoragePersisterOptions)
Options
interface CreateAsyncStoragePersisterOptions { /** The storage client used for setting an retrieving items from cache */ storage: AsyncStorage | undefined | null /** The key to use when storing the cache to localStorage */ key?: string /** To avoid localStorage spamming, * pass a time in ms to throttle saving the cache to disk */ throttleTime?: number /** How to serialize the data to storage */ serialize?: (client: PersistedClient) => string /** How to deserialize the data from storage */ deserialize?: (cachedString: string) => PersistedClient /** How to retry persistence on error **/ retry?: AsyncPersistRetryer}
interface AsyncStorage { getItem: (key: string) => Promise<string | null> setItem: (key: string, value: string) => Promise<unknown> removeItem: (key: string) => Promise<void>}
The default options are:
{ key = `REACT_QUERY_OFFLINE_CACHE`, throttleTime = 1000, serialize = JSON.stringify, deserialize = JSON.parse,}
