⚡How to install Node.js on Windows Server

Node.js brings JavaScript to the server side. It is the foundation for many modern web applications, API servers, and development tools. Installing it on Windows Server is straightforward.

Step 1: Download the installer

1. Open your browser on the VPS

2. Go to nodejs.org

3. Download the LTS version (the one with the long-term support label)

Step 2: Run the installer

1. Double-click the downloaded .msi file

2. Accept the license agreement

3. Keep the default installation path (C:\Program Files\nodejs\)

4. In the Custom Setup screen, make sure npm package manager is checked

5. Check Automatically install the necessary tools (this adds Chocolatey and Python for native modules)

6. Click Install

Step 3: Verify the installation

Open a new Command Prompt or PowerShell:

node --version
npm --version

You should see version numbers for both.

Step 4: Create a test project

mkdir C:\myapp
cd C:\myapp
npm init -y

Now create a simple web server. Create a file called server.js:

const http = require('http');

const server = http.createServer((req, res) => {
  res.writeHead(200, { 'Content-Type': 'text/plain' });
  res.end('ITITAN Hosting Windows VPS running Node.js!\n');
});

server.listen(3000, () => {
  console.log('Server running on port 3000');
});

Run it:

node server.js

Open your browser and go to http://localhost:3000. You should see the message.

Step 5: Open the port in the firewall

To access your Node.js app from outside the VPS, open port 3000:

netsh advfirewall firewall add rule name="Node.js App 3000" dir=in action=allow protocol=TCP localport=3000

Now try accessing http://your-server-ip:3000 from your own browser.

Step 6: Keep your app running with PM2

Node.js apps stop when you close the terminal. PM2 keeps them running and restarts them if they crash.

Install PM2 globally:

npm install -g pm2

Start your app with PM2:

pm2 start server.js --name myapp

Save the process list so it restarts on reboot:

pm2 save

Install PM2 as a Windows service for automatic startup:

pm2-installer

Or use the Windows Task Scheduler to run PM2 at startup.

Step 7: Installing Yarn (optional)

Some projects use Yarn instead of npm:

npm install -g yarn
yarn --version

Step 8: Installing native build tools

If you plan to use packages that need native compilation (like bcrypt or sharp), you need the Windows Build Tools:

npm install -g windows-build-tools

This installs Visual C++ build tools and Python. It takes a few minutes.

Managing multiple Node.js versions

If you work on projects that need different Node.js versions, use nvm-windows:

1. Download the latest installer from github.com/coreybutler/nvm-windows

2. Run the installer

3. Open a new PowerShell as Administrator

Install multiple versions:

nvm install 20.11.0
nvm install 22.0.0

Switch between them:

nvm use 20.11.0
nvm use 22.0.0

Check the active version:

node --version

Common issues

"node is not recognized" Close and reopen your terminal. The PATH variable needs to refresh after installation.

Permission errors On Windows, avoid installing global packages with sudo equivalents. If you get EACCES errors, make sure you are running PowerShell as Administrator.

Port already in use If port 3000 is already taken, use a different port or stop the other application:

netstat -ano | findstr :3000
taskkill /PID <PID> /F

Useful npm commands

Command	What it does
npm init -y	Create a new package.json
npm install express	Install a package
npm install -g pm2	Install a package globally
npm update	Update all packages
npm outdated	Check for outdated packages
npm uninstall express	Remove a package

Conclusion

Node.js is installed and ready on your Windows VPS. You can now run JavaScript applications, API servers, and web apps. With PM2 managing your processes, they will stay online even after you disconnect.
