The React + Node Energy Combo

React excels at constructing quick, dynamic frontends. Node.js shines for server-side APIs and microservices. Collectively, they make a robust stack for full stack apps.

Let’s stroll via integrating React with Node.js:

Serving React Builds

Use Node.js middleware like Specific to serve the React app:

// server.js
app.use(categorical.static(path.be a part of(__dirname, 'shopper/construct')));

app.get('*', (req, res) => {
  res.sendFile(path.be a part of(__dirname, 'shopper/construct', 'index.html));

This serves the React construct from the /construct folder.

Proxying API Requests

Proxy frontend requests to the backend API:

// React

// Server 
app.use('/api', apiRouter);

Arrange a route forwarding to the API server.

Server-Facet Rendering

Use libraries like ReactDOMServer to server-side render parts:

// server.js
app.get('/', (req, res) => {
  const jsx = ReactDOMServer.renderToString(<App />);

This serves absolutely rendered HTML from the React app.

Authentication and Classes

Share authentication classes and information between backend and frontend:

// Backend session 
req.session.consumer = {
  identify: 'John'  

// React can entry by way of proxy
axios.get('/api/consumer') // { identify: 'John' }

Classes allow persisting auth throughout requests.


  • Use Specific to serve React builds
  • Ahead requests to Node.js APIs
  • Server-side render for web optimization
  • Share auth classes between frontend and backend

Combining React and Node.js brings collectively declarative UIs with scalable server infrastructure.
