What are some examples of using redux-persist?

Can you give me some examples of how to use redux-persist in a React application?

Sure! Redux Persist is a library that helps you save your Redux state in local storage. For example, you can configure it like this:

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);

How do I use it with a specific reducer?

You can create a separate persist config for each reducer. For example:

const userPersistConfig = {
  key: 'user',
  storage,
};

const persistedUserReducer = persistReducer(userPersistConfig, userReducer);

What about rehydrating the state?

To rehydrate the state, you just need to wrap your app with the PersistGate component:

import { PersistGate } from 'redux-persist/integration/react';

<PersistGate loading={null} persistor={persistor}>
  <App />
</PersistGate>

Are there any common issues I should be aware of?

Yes, common issues include state not being saved properly if the key is incorrect or if the storage is full. Always check your console for errors!
