createAsyncStoragePersister
安装
此实用程序作为一个单独的包提供，并且可以通过 '@tanstack/query-async-storage-persister' 导入来使用。
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
或
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
或
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
或
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
用法
- 导入 createAsyncStoragePersister 函数
- 创建一个新的 asyncStoragePersister
- 你可以传递任何符合 AsyncStorage 接口的 storage 给它 - 下面的例子使用了来自 React Native 的 async-storage
- 通过使用 PersistQueryClientProvider 组件来包裹你的应用。
tsx
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: {
gcTime: 1000 * 60 * 60 * 24, // 24 hours
},
},
})
const asyncStoragePersister = createAsyncStoragePersister({
storage: AsyncStorage,
})
const Root = () => (
<PersistQueryClientProvider
client={queryClient}
persistOptions={{ persister: asyncStoragePersister }}
>
<App />
</PersistQueryClientProvider>
)
export default Root
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: {
gcTime: 1000 * 60 * 60 * 24, // 24 hours
},
},
})
const asyncStoragePersister = createAsyncStoragePersister({
storage: AsyncStorage,
})
const Root = () => (
<PersistQueryClientProvider
client={queryClient}
persistOptions={{ persister: asyncStoragePersister }}
>
<App />
</PersistQueryClientProvider>
)
export default Root
重试
重试的工作方式与 SyncStoragePersister 相同，除了它们也可以是异步的。你也可以使用所有预定义的重试处理程序。
API
createAsyncStoragePersister
调用此函数以创建一个 asyncStoragePersister，你可以在以后与 persistQueryClient 一起使用。
tsx
createAsyncStoragePersister(options: CreateAsyncStoragePersisterOptions)
createAsyncStoragePersister(options: CreateAsyncStoragePersisterOptions)
选项
tsx
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>
}
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>
}
默认选项是
tsx
{
key = `REACT_QUERY_OFFLINE_CACHE`,
throttleTime = 1000,
serialize = JSON.stringify,
deserialize = JSON.parse,
}
{
key = `REACT_QUERY_OFFLINE_CACHE`,
throttleTime = 1000,
serialize = JSON.stringify,
deserialize = JSON.parse,
}
