Deploying Your First Node.js App on AWS EC2: A Beginner's Guide to Cloud Success

Title : Deploying Your First Node.js Application on AWS EC2 : A Step-by-Step Guide

Introduction:

In this Blog, we'll explore the process of deploying a Node.js application on AWS EC2. We'll cover the necessary steps to set up an EC2 instance, install Node.js, and deploy our application on the cloud.

Prerequisites:

• Basic knowledge of Node.js and AWS

• An AWS account with access to EC2

• A Node.js application to deploy

Deploying a Node.js Application on AWS EC2

Testing the Project Locally first

Before deploying our Node.js application on AWS EC2, let's test it locally to ensure everything is working as expected.

1. Clone the project from GitHub:

COPY

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

2. Set up the environment variables in a .env file:

COPY

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

PUBLISHABLE_KEY=""
SECRET_KEY=""

3. Initialise and start the project:

COPY

npm install
npm run start

Open a web browser and navigate to http://localhost:3000 to verify that the application is running locally.

Setting up an AWS EC2 Instance

Now that our application is running locally, let's set up an AWS EC2 instance to deploy it.

1. Create an IAM user and log in to your AWS Console:

   • Access Type: Password

   • Permissions: Admin

2. Create an EC2 instance:

   • Select an OS image: Ubuntu

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

   • Instance type: t2.micro

3. Connect to the instance using SSH:

COPY

ssh -i instance.pem ubuntu@<IP_ADDRESS>

Configuring Ubuntu on Remote VM

Once connected to the instance, let's configure Ubuntu on the remote VM.

1. Update the outdated packages and dependencies:

COPY

sudo apt update

2. Install Git: Guide by DigitalOcean

3. Configure Node.js and npm: Guide by DigitalOcean

Deploying the Project on AWS

Now that our EC2 instance is set up, let's deploy our project on AWS.

1. Clone the project in the remote VM:

COPY

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

2. Set up the environment variables in a .env file:

COPY

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

PUBLISHABLE_KEY=""
SECRET_KEY=""

For this project, we'll have to set up an Elastic IP Address for our EC2, which will be our DOMAIN.

3. Initialise and start the project:

COPY

npm install
npm run start

Note: We will have to edit the inbound rules in the security group of our EC2 to allow traffic from our particular port.
