What is redux-persist and how does it work?

Redux-persist is a library that helps you save your Redux state in local storage, making it persistent across sessions.

How do I set it up in my React application?

To set it up, first install it using npm, then configure it with your Redux store and specify the storage.

Can you show me a code example?

Sure! Here's a basic example:

import { createStore } from 'redux';
import { persistStore, persistReducer } from 'redux-persist';
import storage from 'redux-persist/lib/storage';

const persistConfig = { key: 'root', storage };
const persistedReducer = persistReducer(persistConfig, rootReducer);
const store = createStore(persistedReducer);
const persistor = persistStore(store);

What are the benefits of using redux-persist?

The main benefits include improved user experience by retaining state, and reduced data fetching on app reload.
