Deploying a Node.js Application on AWS ECsing Tabby SSH Client

Deploying a Node.js application on an AWS EC2 instance is a crucial skill for backend developers. This guide walks you through deploying your Node.js application using the Tabby SSH Client. Let’s get started!

Prerequisites

1. AWS EC2 Instance

• Ensure your EC2 instance is launched with the following:
  • Security Group allowing:
    • SSH (port 22)
    • HTTP (port 80)
    • HTTPS (port 443)

2. Tabby SSH Client

• Installed and configured on your local machine.

• Your private key for EC2 access added to Tabby.

3. Dependencies

• Node.js application code hosted on a Git repository.
• Optional: A domain name for production HTTPS setup.

Step-by-Step Deployment

Step 1: Connect to the EC2 Instance

1. Launch the Tabby SSH Client.

2. Connect to the EC2 instance using:

   • Public IP address
   • Private key associated with the instance.

Step 2: Install Required Dependencies on EC2

Once connected, update the system and install necessary packages.

Update System Packages

sudo apt update && sudo apt upgrade -y

Install Node.js and npm

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

Install Git

sudo apt install git -y

Install PM2 (Optional, for Production Management)

sudo npm install -g pm2

Step 3: Clone Your Node.js Repository

• Navigate to your desired directory (e.g., /var/www):

cd /var/www

• Clone the repository:

git clone <your-repo-url> app-name
cd app-name

Step 4: Set Up the Application

Install Node.js Dependencies

npm install

Configure Environment Variables

• Create an .env file:

touch .env

• Open the file in a text editor to add your environment variables:

nano .env

• Save and exit the editor.

Step 5: Start the Application

Run the Application

npm run start

Or Use PM2 for Process Management

pm2 start app.js  # Replace 'app.js' with your main application file

Step 6: Access the Application

• Open a browser and navigate to:

http://<your-ec2-public-ip>:<port>

Example:

http://13.60.229.203:5001/

• You should see your application running.

Next Steps

Optional Enhancements

• Domain Setup: Point your domain to the EC2 public IP using DNS records.
• SSL with Let’s Encrypt: Use Certbot to enable HTTPS.
• Load Balancing: Add AWS Elastic Load Balancer for scaling.
