React Native Async Storage

An asynchronous, unencrypted, persistent, key-value storage system for React Native.

Getting Started


$ yarn add @react-native-community/async-storage


  • React Native 0.60+

CLI autolink feature links the module while building the app.

  • React Native <= 0.59
$ react-native link @react-native-community/async-storage

Note For iOS using cocoapods, run:

$ cd ios/ && pod install

See docs for manual linking guide

Upgrading to React Native 0.60+

New React Native comes with autolinking feature, which automatically links Native Modules in your project. In order to get it to work, make sure you unlink Async Storage first:

$ react-native unlink @react-native-community/async-storage



import AsyncStorage from '@react-native-community/async-storage';

Store data

storeData = async () => {
  try {
    await AsyncStorage.setItem('@storage_Key', 'stored value')
  } catch (e) {
    // saving error

Read data

getData = async () => {
  try {
    const value = await AsyncStorage.getItem('@storage_Key')
    if(value !== null) {
      // value previously stored
  } catch(e) {
    // error reading value


See docs for api and more examples or advanced usages.

Writing tests

Using Jest for testing? Make sure to check out docs on how to integrate it with this module.
