app.listen(3002, () => { console.log('Order Service listening on port 3002'); });

mongoose.connect('mongodb://localhost/orderdb', { useNewUrlParser: true, useUnifiedTopology: true }); mongoose

app.listen(3001, () => { console.log('Product Service listening on port 3001'); });

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

app.get('/products', (req, res) => { Product.find().then((products) => { res.send(products); }); }); const User = mongoose

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.

const User = mongoose.model('User', { name: String, email: String });

app.listen(3000, () => { console.log('User Service listening on port 3000'); });

const Order = mongoose.model('Order', { userId: String, productId: String, quantity: Number });

The React frontend will communicate with each microservice using RESTful APIs.
