Redux Persist

This library passes the redux store to localStorage.

First install redux persist library to your project:

npm install redux-persist

Then set up redux-persist in your store like so:

import { compose, createStore, applyMiddleware } from "redux";
import { persistStore, persistReducer } from "redux-persist";
import storage from "redux-persist/lib/storage";
import logger from "redux-logger";

const persistConfig = {
  key: "root",
  blacklist: ["user"],

const persistedReducer = persistReducer(persistConfig, rootReducer);

const middleWares = [logger];

const composedEnhancers = compose(applyMiddleware(...middleWares));

export const store = createStore(

export const persistor = persistStore(store);

The above excludes adding the user reducer to persist (blacklist: ["user"]) because its already being added to the cache.

Now you need to edit your main index.js file to add the PersistGate with the new persist config attached like so:

import React from "react";
import ReactDOM from "react-dom/client";
import { BrowserRouter } from "react-router-dom";
import { Provider } from "react-redux";
import { PersistGate } from "redux-persist/es/integration/react";

import App from "./App";
import { store, persistor } from "./store/store";

import "./index.scss";

const root = ReactDOM.createRoot(document.getElementById("root"));
    <Provider store={store}>
      <PersistGate loading={null} persistor={persistor}>
          <App />

Now when you refresh your browser you’ll see all the store reducers maintain their state.
