Basic Usage

``sh
npm install --save apollo3-cache-persist
`

or

`sh
yarn add apollo3-cache-persist
`

To get started, simply pass your Apollo cache and an
underlying storage provider to persistCache.

By default, the contents of your Apollo cache will be immediately restored
(asynchronously, see how to persist data before rendering), and will be persisted upon every write to the cache (with a
short debounce interval).

#### React Native

`js
import AsyncStorage from '@react-native-async-storage/async-storage';
import { InMemoryCache } from '@apollo/client/core';
import { persistCache, AsyncStorageWrapper } from 'apollo3-cache-persist';

const cache = new InMemoryCache({...});

// await before instantiating ApolloClient, else queries might run before the cache is persisted
await persistCache({
cache,
storage: new AsyncStorageWrapper(AsyncStorage),
});

// Continue setting up Apollo as usual.

const client = new ApolloClient({
cache,
...
});
`

#### Web

`js
import { InMemoryCache } from '@apollo/client/core';
import { persistCache, LocalStorageWrapper } from 'apollo3-cache-persist';

const cache = new InMemoryCache({...});

// await before instantiating ApolloClient, else queries might run before the cache is persisted
await persistCache({
cache,
storage: new LocalStorageWrapper(window.localStorage),
});

// Continue setting up Apollo as usual.

const client = new ApolloClient({
cache,
...
});
