How to store tokens in react native?

If you’re using create-react-native-app or exp, you can use Expo.SecureStore to store your token.

import {SecureStore} from 'expo';

await SecureStore.setItemAsync('secure_token','sahdkfjaskdflas$%^&');
const token = await SecureStore.getItemAsync('secure_token');
console.log(token); // output: sahdkfjaskdflas$%^&

Details: https://docs.expo.io/versions/latest/sdk/securestore

Update in Dec 2020:

The SecureStore module is now become expo-secure-store

import * as SecureStore from 'expo-secure-store';

await SecureStore.setItemAsync('secure_token','sahdkfjaskdflas$%^&');
const token = await SecureStore.getItemAsync('secure_token');
console.log(token); // output: sahdkfjaskdflas$%^&
