How to Deploy Node.js App? Print

Deploying a Node.js application requires a server that can run Node processes. BurjHost supports Node.js on specific plans (usually VPS or dedicated servers). This guide assumes you have a VPS.

Prerequisites:

• A VPS with Node.js and npm installed.

• Your application code ready (e.g., an Express.js app).

Step 1: Install Node.js (if not already installed)
Connect via SSH and install Node.js (example for Ubuntu/Debian):

curl -fsSL https://deb.nodesource.com/setup_18.x | sudo -E bash -
sudo apt-get install -y nodejs

Verify: node -v and npm -v

Step 2: Upload Your Application

• Use Git (clone your repository) or SCP/rsync to transfer your app files to the server.

• Example using Git:

  bash

  cd /var/www
  git clone https://github.com/yourusername/your-app.git
  cd your-app

Step 3: Install Dependencies

npm install

Step 4: Configure Environment Variables
Create a .env file or set environment variables as needed for your app.

Step 5: Run the Application (with Process Manager)
Use PM2 to keep your app running permanently:

npm install -g pm2
pm2 start app.js --name my-app  # Replace app.js with your entry file
pm2 startup  # Ensures app restarts if server reboots
pm2 save

Step 6: Set Up a Reverse Proxy (for Web Access)
To access your app via a domain (port 80/443), configure Apache or Nginx as a reverse proxy. For example, in Nginx:

server {
    listen 80;
    server_name yourdomain.com;
    
    location / {
        proxy_pass http://localhost:3000;  # Your Node.js port
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection 'upgrade';
        proxy_set_header Host $host;
        proxy_cache_bypass $http_upgrade;
    }
}

Your Node.js app is now live!
