Deploying a Node.js application on a VPS (Virtual Private Server) gives you full control over performance, security, and scalability. With Maavee Systems, you also get built-in infrastructure advantages like a perimeter firewall, optional static IPs, and managed SSL via Maavee Load Balancer.

This guide shows both:

Maavee Load Balancer is a specially configured software load balancer designed to maintain high-speed, reliable traffic. It protects you from complex configuration issues and ensures that whatever you build here remains portable across any cloud provider in the world.

What You Need Before Starting

Connect to and Update Your VPS Server

ssh root@your-server-ip
sudo apt update && sudo apt upgrade -y

Create a Sample Application

const express = require('express');
const app = express();
const PORT = process.env.PORT || 3000;

// Middleware to parse JSON bodies
app.use(express.json());

// 1. A basic GET route for the homepage
app.get('/', (req, res) => {
  res.send('<h1>Welcome to the Node.js Web App</h1><p>The server is running smoothly.</p>');
});

// 2. A JSON API route
app.get('/api/status', (req, res) => {
  res.json({
    status: 'online',
    timestamp: new Date().toISOString(),
    uptime: process.uptime()
  });
});

// 3. A POST route to receive data
app.post('/api/data', (req, res) => {
  const receivedData = req.body;

  if (!receivedData.name) {
    return res.status(400).json({ error: 'Please provide a name.' });
  }

  res.status(201).json({
    message: 'Data received successfully',
    yourData: receivedData
  });
});

// 4. Handle 404 - Keep this at the end of your routes
app.use((req, res) => {
  res.status(404).send('Resource Not Found');
});

// Start the server
app.listen(PORT, '0.0.0.0', () => {
  console.log(`Server is running at http://localhost:${PORT}`);
});

This is the main entry point for your application. app.js

How it Works

Important Requirement

To use this setup effectively:

The Firewall

Maavee provides multi-layered protection:

Perimeter Firewall (External to the VPS)

Internal Firewall (iptables / UFW)

You control the rules inside the VPS:

pm2 start app.js
pm2 startup
pm2 save

Domain and DNS Configuration

To make your application accessible via a custom domain, you have two primary paths depending on your chosen architecture:

For Direct VPS Deployment

Point your domain's A Record directly to your VPS’s public IP address. If using Nginx, you will then manage SSL certificates locally using Certbot.

For Maavee Load Balancer (MLB) Setup

Point your domain's CNAME Record to loadb.maavee.com. The Maavee Load Balancer will automatically handle SSL termination and route traffic to your VPS. This ensures your application remains resilient even if your underlying VPS IP changes.

Final Thoughts

Maavee Systems provides flexibility at every layer of your stack:

For most production workloads, the MLB + Managed SSL provides security, simplicity, and high-speed traffic handling. By offloading SSL and load balancing to Maavee's specialized infrastructure, you can focus entirely on building your application.
