React native and redux persist not working

I am using redux-persist to store the data in my react-native app. This is the code:

store.js 

import { createStore, compose, applyMiddleware } from 'redux';
import thunk from 'redux-thunk';
import {
  persistStore,
 persistCombineReducers,
} from 'redux-persist';
import { AsyncStorage } from 'react-native';
import { composeWithDevTools } from 'redux-devtools-extension';
import user from './reducers/user';
import auth from './reducers/auth';

const config = {
  key: 'root',
  storage: AsyncStorage,
};

const reducers = persistCombineReducers(config, {
  user,
  auth
});

export const configureStore = () => {
 const store = createStore(
  reducers,
   compose(
    applyMiddleware(thunk),
    )
  );
  const persistor = persistStore(store);

  return { persistor, store };
};

Then in the App.js I have this :

const { persistor, store } = configureStore();
 const onBeforeLift = () => {
  // take some action before the gate lifts
  store.dispatch(startingApp());
}
return (
  <Provider store={store}>
    <PersistGate
      loading={<HomeLoader />}
      onBeforeLift={onBeforeLift}
      persistor={persistor}>
        <RootNav />
      </PersistGate>
  </Provider>

Everything works fine when I dispatch and action from the App.js componentDidMount. The problem is that when I fire the action from component, for example, the state is not stored, so when I restart the app the state is gone.

What I do in is just calling the action and passing the data:

this.props.onSetAuthData(data.credentials);

The state is updated as I can see in the console, but if I restart the app, only the state created by the action in App.js is saved, not the one in

Maybe this has to do with the RootNav component ?

maybe I am exporting wrong the reducers? I have const user = (state = initialState, action = {}) => {} export default user. Same for the other reducer: const auth = (state = initialState, action = {}) => {} export default auth.

Then I export with combineReducers({auth, user})

Is this wrong?

In my case it was actually a problem with the AsyncStorage library itself(also see this issue).

I ended up writing my own Nativemodule with getItem, setItem, and removeItem etc methods, after which it worked seamlessly.

I added more details on my friend's blog here

Hope it helps someone.

sometimes it calls an error with the key in persistConfig. try key: 'primary'

const primary = {
key: 'root',
storage: AsyncStorage,
blacklist: [],
whitelist: ['user'],
};

Use tool like Reacttotron to see if your store is persisted or not.

https://github.com/infinitered/reactotron

If it's already persisted your component should wait until the store rehydrated on app launch. Sometimes I can't use the redux persist using persistgate to wait for the persisted store to be rehydrated. So I set the store and persistor into state on async componentWillMount then in your render, check if the store is not empty (null) and already rehydrated then load your app.

  constructor(){
    super();
    this.state = {store: null, persistor: null}
  }
  async componentWillMount () {
    const store = configureStore();
    this.setState({ store: store.store })
    this.setState({ persistor: store.persistor })
  }
  render(){
    return (
    if (this.state.store === null) {
      return (
        <View>
          <Text>Loading...</Text>
        </View>
        );
    }
    <Provider store={this.state.store} persistor={this.state.persistor}>
          <RootNav />
    </Provider>

Also try to change your storage from AsyncStorage to storage.

const config = {
  key: 'root',
  storage,
};

First import the storage import storage from 'redux-persist/es/storage';
