Deploying a Node Js Application on AWS EC2

GitHub Link - https://github.com/SUBHAM-NANDI/Project1-Deploying-NodeJs-Application-on-AWS

Testing the project locally

Clone this project on the local machine.

git clone https://github.com/SUBHAM-NANDI/AWS-Session.git

Open the project on VSCode.
Create an environment variable(.env) file.

 touch .env

This will create a hidden .env file.

Environment variable files are essential for securely managing configuration settings and secrets across different environments (development, testing, production). They separate configuration from code, enhance security by preventing hardcoding of sensitive data, ensure consistency, simplify deployment, and support easy environment-specific configurations. This centralized management approach promotes maintainability and flexibility, making managing and updating settings easier without altering the codebase.

Setup the following environment variables - (.env) file

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

PUBLISHABLE_KEY=""
SECRET_KEY=""

Create a Stripe account for free and copy the publishable and secret keys, respectively.

Initialise all dependencies and start the project

npm install 
npm run start

Set up an AWS EC2 instance

Create an IAM user & login to your AWS Console
- Access Type - Password
- Permissions - Admin
Create an EC2 instance
- Select an OS image - Ubuntu
- Create a new key pair & download .pem file
- Instance type - t2.micro
Connecting to the instance using ssh

Open an SSH client.
Locate your private key file. The key used to launch this instance is node.js-app-deploy.pem
Run this command, if necessary, to ensure your key is not publicly viewable.
Change the permission of the .pem file using the below cmd.

chmod 400 "instance.pem"

Connect to the ec2 instance using the below cmd

ssh -i instance.pem ubunutu@<PUBLIC IP_ADDRESS>

Updating the outdated packages and dependencies

sudo apt update

Install Git - For more info please follow Guide by DigitalOcean

sudo apt install git

Configure Node.js and npm - For more info please follow Guide by DigitalOcean

sudo apt install nodejs
sudo apt install npm

Deploying the project on AWS

Clone this project in the remote VM

git clone https://github.com/SUBHAM-NANDI/AWS-Session.git

Create and open an environment variable(.env) file in the project folder.

touch .env
vim .env

Setup the following environment variables - (.env) file

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 & that would be our DOMAIN

Initialise and start the project

npm install
npm run start

NOTE - We will have to edit the inbound rules in the security group of our EC2, in order to allow traffic from our particular port
Go to the EC2 instance and go to security. Click on Security groups and then edit the Inbound Roules.
Add a separate Inbound rule with *Type - Custom TCP * and post range - 3000 and then save.
