A simple way to save your Redux state in localStorage.

localStateRedux.js

let propsToSave = [];

export const setProps = (props) => propsToSave = props;
export const getLocalStore = () => JSON.parse(localStorage.getItem('state'));
export const setLocalStore = (store) => {
  var toSave = {};
  var state = store.getState();
  propsToSave.forEach(p => toSave[p] = state[p]);
  localStorage.setItem('state', JSON.stringify(toSave));
};

usage.js

import { setProps, getLocalStore, setLocalStore } from './localStore'
import * as reducers from './reducers';
 
setProps(['keys', 'to', 'save', 'go', 'here']);
const reducer = combineReducers(reducers);
const store = createStore(reducer, getLocalStore());

function init () {
  setLocalStore(store);
  // ...
}
store.subscribe(init);
init();
