Error when @react-native-async-storage/async-storage is not working with persist in rt2zz redux-persist

Explanation of the problem

The issue at hand is related to difficulty in using the @react-native-async-storage/async-storage package in a React Native application. The problem is that, when attempting to use this package, it is not working as expected, and the old package @react-native-community/async-storage which is deprecated, is still working.

The problem is reproducible when using React Native version 0.64 on an android emulator. This package is used for storing data locally in the device’s storage. The user is testing the package on android emulator and facing difficulty in using the package. The package is not working as expected and the user is questioning if redux-persist will support the package.

The question is if the package redux-persist will support the package @react-native-async-storage/async-storage, which is not working as expected. It’s important to note that the old package @react-native-community/async-storage is deprecated, but it still works. It may be useful to check the official documentation of the package and see if there are any updates or fixes for the issue. Also, checking the issue list in the package repository, and see if anyone else has reported similar problems and if there are any solutions or workarounds.

A brief introduction to rt2zz redux-persist

rt2zz redux-persist is a package that allows you to persist the state of your Redux store to a storage engine, such as AsyncStorage or LocalStorage. It provides a set of actions and reducers that can be used to handle the persistence of your application’s state. By persisting your state, you can easily keep your application’s state in sync across different sessions, allowing you to handle complex state management scenarios with ease.

The package provides several functions that can be used to handle the persistence of your application, such as createPersist and createPersistMiddleware. The createPersist function can be used to create a new reducer that can be used to update the state based on the current storage. The createPersistMiddleware can be used to intercept the persistence actions and update the state accordingly.

The package can be configured with different storage engines, such as AsyncStorage and LocalStorage. The package also allows you to configure the whitelist and blacklist of the state that needs to be persisted. Additionally, rt2zz redux-persist also provides a persistStore function that can be used to subscribe the store and listen to the rehydration event, and call the callback function when the store is rehydrated. This allows you to handle the rehydration and hydration of the store.

Most popular use cases for rt2zz redux-persist

  1. Persisting the state of your Redux store to a storage engine: rt2zz redux-persist can be used to persist the state of your Redux store to a storage engine such as AsyncStorage or LocalStorage. This allows you to keep your application’s state in sync across different sessions and handle complex state management scenarios with ease.
import { createPersist, createPersistMiddleware } from 'rt2zz-redux-persist';

const persistConfig = {
  storage: AsyncStorage,
  whitelist: ['auth'],
  version: 1,
};

const persist = createPersist(persistConfig);
const persistMiddleware = createPersistMiddleware();

const store = createStore(
  persist.reducer,
  composeWithDevTools(applyMiddleware(persistMiddleware))
);

persistStore(store);
  1. Handling rehydration and hydration of the store: rt2zz redux-persist provides a persistStore function that can be used to subscribe the store and listen to the rehydration event, and call the callback function when the store is rehydrated. This allows you to handle the rehydration and hydration of the store.
persistStore(store, undefined, () => {
  // handle store rehydration here
});
  1. Whitelisting and blacklisting of the state that needs to be persisted: With the package, you can whitelist or blacklist the state that needs to be persisted. This allows you to control which state should be persisted and which state should not be persisted.
const persistConfig = {
  storage: AsyncStorage,
  whitelist: ['auth'],
  blacklist: ['counter'],
  version: 1,
};
