How can I persist or save states in reactjs?

Question

I am currently working on a single page application using ReactJS. I have to use local storage to save states but it's not safe and secure. I want to know if there is any possible safe way to use local storage for states?

You can use the redux-persist package for persist state.

import { createStore, applyMiddleware } from 'redux';
import thunkMiddleware from 'redux-thunk';
import { createLogger } from 'redux-logger';
import rootReducer from '../_reducers';
import { composeWithDevTools  } from 'redux-devtools-extension';
import { persistStore, persistReducer } from 'redux-persist'
import storage from 'redux-persist/lib/storage'
const persistConfig = {
    key: 'chedsk',
    storage,
  }
const loggerMiddleware = createLogger();

const persistedReducer = persistReducer(persistConfig, rootReducer)
 
const composeEnhancers = composeWithDevTools({trace: true, traceLimit: 20});
export const store = createStore(
    persistedReducer,composeEnhancers( applyMiddleware(
        thunkMiddleware,
        loggerMiddleware
    ))
   
)
export const persistor = persistStore(store)


import { store, persistor } from './_helpers/store';
import { PersistGate } from 'redux-persist/integration/react'
render(
    <Provider store={store}>
        <PersistGate loading={null} persistor={persistor}>
            <App />
        </PersistGate>
    </Provider>,
    document.querySelector('#root')
);
