How to handle route transitions in a React app without losing Redux state

Question

Can you explain with the help of code How to handle route transitions in a React app without losing Redux state?

Answer 1

To handle route transitions in a React app without losing Redux state, follow these best practices:

1. Use React Router for Navigation

Ensure you are using React Router for handling route transitions:

import { BrowserRouter as Router, Route, Routes } from 'react-router-dom';

<Router>

  <Routes>

    <Route path="/" element={<Home />} />

    <Route path="/dashboard" element={<Dashboard />} />

  </Routes>

</Router>

2. Persist Redux State with Redux Persist

Install and configure Redux Persist to keep state across route changes and page reloads:

npm install redux-persist

import { persistStore, persistReducer } from 'redux-persist';

import storage from 'redux-persist/lib/storage';

import { createStore } from 'redux';

const persistConfig = { key: 'root', storage };

const persistedReducer = persistReducer(persistConfig, rootReducer);

const store = createStore(persistedReducer);

const persistor = persistStore(store);

Wrap your app with PersistGate:

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

<Provider store={store}>

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

    <App />

  </PersistGate>

</Provider>
