Microservices With Node Js And React Download Apr 2026

const express = require('express'); const app = express(); const mongoose = require('mongoose');

The Order Service will be built using Node.js and Express.js. It will be responsible for managing orders.

mongoose.connect('mongodb://localhost/userdb', { useNewUrlParser: true, useUnifiedTopology: true }); Microservices With Node Js And React Download

app.post('/users', (req, res) => { const user = new User(req.body); user.save((err) => { if (err) { res.status(400).send(err); } else { res.send({ message: 'User created successfully' }); } }); });

The Product Service will also be built using Node.js and Express.js. It will be responsible for managing the product catalog. const express = require('express'); const app = express();

In this guide, we have explored how to build microservices using Node.js and React. We have created three microservices: User Service, Product Service, and Order Service, each responsible for a specific business capability. The React frontend communicates with each microservice using RESTful APIs.

app.listen(3002, () => { console.log('Order Service listening on port 3002'); }); It will be responsible for managing the product catalog

function App() { const [products, setProducts] = useState([]); const [user, setUser] = useState({});

const handleLogin = (event) => { event.preventDefault(); axios.post('http://localhost:3000/users', { name: 'John Doe', email: 'johndoe@example.com' }) .then((response) => { setUser(response.data); }) .catch((error) => { console.error(error); }); };
