Microservices With Node Js And React Download -

export default App; npm start The React app will run on http://localhost:3000 and communicate with the API Gateway. Step 6: Dockerizing Services Create a Dockerfile for each service.

Now the React app can make requests to http://localhost:5000/users instead of directly to each service. Sometimes services need to communicate without blocking the request-response cycle. Redis Pub/Sub is a lightweight solution. Example: When a user is created, notify the email service. In user-service (publisher):

app.use('/orders', createProxyMiddleware({ target: 'http://localhost:4003', changeOrigin: true, })); microservices with node js and react download

// User Schema const userSchema = new mongoose.Schema({ name: String, email: String, createdAt: { type: Date, default: Date.now }, });

useEffect(() => { fetchUsers(); }, []);

app.use('/products', createProxyMiddleware({ target: 'http://localhost:4002', changeOrigin: true, }));

// Publish event await publisher.publish('user-created', JSON.stringify(newUser)); export default App; npm start The React app

return ( <div> <h1>Microservices User Management</h1> <form onSubmit={createUser}> <input placeholder="Name" value={name} onChange={(e) => setName(e.target.value)} /> <input placeholder="Email" value={email} onChange={(e) => setEmail(e.target.value)} /> <button type="submit">Add User</button> </form> <ul> {users.map(user => ( <li key={user._id}>{user.name} - {user.email}</li> ))} </ul> </div> ); }

Run everything with:

app.post('/users', async (req, res) => { const newUser = new User(req.body); await newUser.save(); res.status(201).json(newUser); });
