Deploying a Node.js Application on AWS EC2 🚀

This guide provides a step-by-step process to deploy a Node.js application on an AWS EC2 instance. It covers everything from testing locally to deploying and configuring the application on a live server.

---

Testing the Project Locally 🛠️

1. Clone the Repository

git clone https://github.com/verma-kunal/AWS-Session.git

2. Set Up Environment Variables

Create a .env file in the root directory and add the following:

DOMAIN= ""
PORT=3000
STATIC_DIR="./client"

PUBLISHABLE_KEY=""
SECRET_KEY=""

3. Initialize and Start the Project

Install dependencies and start the project locally:

npm install
npm run start

Setting Up an AWS EC2 Instance ☁️

1. Create an IAM User

• Login to AWS Console and create an IAM user.

• Select the following:

  • Access Type: Password

  • Permissions: Admin Access

2. Launch an EC2 Instance

• Go to the EC2 Dashboard and launch an instance:

  • OS Image: Ubuntu (latest LTS)

  • Instance Type: t2.micro (free tier eligible)

  • Key Pair: Create a new key pair and download the .pem file.

3. Connect to the EC2 Instance

Use the following SSH command:

ssh -i instance.pem ubuntu@<EC2_PUBLIC_IP>

Configuring Ubuntu on Remote VM 🖥️

1. Update System Packages

Update outdated packages to ensure system compatibility:

sudo apt update
sudo apt upgrade -y

2. Install Git

Follow this guide by DigitalOcean to install Git:

sudo apt install git -y

3. Install Node.js and npm

Follow this guide by DigitalOcean to set up Node.js and npm:

sudo apt install nodejs -y
sudo apt install npm -y

Deploying the Project on AWS 🌐

1. Clone the Repository on EC2

git clone https://github.com/verma-kunal/AWS-Session.git

2. Set Up Environment Variables

Create a .env file in the project directory on the server:

DOMAIN= "<Elastic_IP>"
PORT=3000
STATIC_DIR="./client"

PUBLISHABLE_KEY=""
SECRET_KEY=""

⚡ Tip: Set up an Elastic IP Address to ensure a static IP for your EC2 instance. Use this IP as the DOMAIN value.

3. Initialize and Start the Project

Install the required dependencies and start the application:

npm install
npm run start

4. Edit Security Group Inbound Rules

To allow traffic to the application:

• Go to EC2 Dashboard > Security Groups > Edit Inbound Rules.

• Add a rule:

  • Type: Custom TCP

  • Port: 3000

  • Source: 0.0.0.0/0 (or restrict to specific IPs for security)

Conclusion 🎉

Your Node.js application is now live on AWS!
You can access it using the following URL in your browser:

arduinoCopy codehttp://<Elastic_IP>:3000
