localStorage.js

export const loadState = () => {
  try {
    const auth = localStorage.getItem('name');
    if (auth === null) return undefined;
    return JSON.parse(auth);
  } catch (err) {
    return undefined;
  }
}

export const saveState = state => {
  try {
    const auth = JSON.stringify(state);
    localStorage.setItem('name', auth);
  } catch (err) {
    console.log(err);
  }
}

import { loadState, saveState } from '../Data/localStorage';
import throttle from 'lodash/throttle';

const persistedState = loadState();

const store = createStore(

store.subscribe(throttle(() => saveState({
  auth: store.getState().auth
}), 1000));
