createAsyncStoragePersister
Installation
This utility comes as a separate package and is available under the '@tanstack/query-async-storage-persister' import.
bash
npm install @tanstack/query-async-storage-persister @tanstack/react-query-persist-client npm install @tanstack/query-async-storage-persister @tanstack/react-query-persist-client or
bash
pnpm add @tanstack/query-async-storage-persister @tanstack/react-query-persist-client pnpm add @tanstack/query-async-storage-persister @tanstack/react-query-persist-client or
bash
yarn add @tanstack/query-async-storage-persister @tanstack/react-query-persist-client yarn add @tanstack/query-async-storage-persister @tanstack/react-query-persist-client or
bash
bun add @tanstack/query-async-storage-persister @tanstack/react-query-persist-client bun add @tanstack/query-async-storage-persister @tanstack/react-query-persist-client Usage
- Import the createAsyncStoragePersister function
- Create a new asyncStoragePersister
- you can pass any storage to it that adheres to the AsyncStorage interface - the example below uses the async-storage from React Native.
- storages that read and write synchronously, like window.localstorage, also adhere to the AsyncStorage interface and can therefore also be used with createAsyncStoragePersister.
- Wrap your app by using PersistQueryClientProvider component.
tsx

Retries work the same as for a SyncStoragePersister, except that they can also be asynchronous. You can also use all the predefined retry handlers.
API
createAsyncStoragePersister
Call this function to create an asyncStoragePersister that you can use later with persistQueryClient.
tsx

tsx
