Easy Steps to Launch Your Node.js Application on AWS

Testing on a Local System

Step 1: Clone the application to your local system

Step 2: Create an environment variables file named .env and specify the variables

Step 3: Install NPM packages

npm install

Step 4: Run the application on your local system

npm run start

Deploying on an AWS EC2 Instance

Now that the application is working well on your local system, it's time to deploy it on an AWS EC2 instance.

Step 1: Create an IAM user and assign a specific role to that user.

Important: We are using a simple password here, but when working in an organization, it's highly recommended to use a secure password.

Step 2: Login as an IAM User using the credentials provided while creating the user.

Step 3: Create EC2 instance

Step 4: Connect to this EC2 instance.

Step 5: Updating the outdated packaged and dependencies

sudo apt-get update

Step 6: install git on you install, to check where its already installed or not, type this command

git --version

if the git is installed on your ec2 instance then it will show the version of the git.

Step 7: Configure Node.js and npm- Guide by DigitalOcean

Step 8: Install npm

sudo apt install npm

Check npm —version, to see if its installed or not.

Step 9: Clone your application from git to the server using git clone <url> command. Cloned application on the server.

Step 10: Setting up Environment Variables file, what I have done on local machine

Step 11: Install NPM

npm install

Step 12: Run the application on local system

npm run start

Step 13: Update the Security Group of the EC2 instance to open port 3000, allowing access to the application running on that port.

Step 14: Copy the public IP address of the EC2 instance and the port number where the application is running. Then, try to access the application.
