node app not visible in browser aws ec2

To make a Node.js app visible in a browser on an AWS EC2 instance, you can follow these steps:

  1. Create an EC2 instance: Start by launching an EC2 instance on AWS. Choose an appropriate instance type and configure the necessary security groups and key pairs.

  2. Connect to the instance: Use SSH or the AWS Management Console to connect to your EC2 instance.

  3. Install Node.js: Update the package manager on your EC2 instance, and then install Node.js. This can be done using the following commands:

sudo apt update
sudo apt install nodejs

  1. Create your Node.js app: Write your Node.js application code or copy your existing application code to the EC2 instance. Make sure to include a valid package.json file describing your application dependencies.

  2. Install application dependencies: In the directory where your Node.js app is located, run the following command to install the required dependencies:

npm install
  1. Start the Node.js app: Start your Node.js app by running the following command:
node app.js

Replace app.js with the name of your application's entry point file if it's different.

  1. Configure security groups: Ensure that the security group associated with your EC2 instance allows inbound traffic on the port your Node.js app is listening on. By default, Node.js apps often listen on port 3000, but you can choose a different port if desired.

  2. Open the port in the firewall: If you're using a Linux distribution with a firewall (e.g., ufw), open the port your Node.js app is listening on. For example, to open port 3000, run:

sudo ufw allow 3000
  1. Access your app in the browser: Open a web browser and enter the public IP address or public DNS name of your EC2 instance, followed by the port number your Node.js app is listening on (e.g., http://<public-ip>:3000). You should now be able to access your Node.js app in the browser.

By following these steps, you should be able to make your Node.js app visible in a browser on an AWS EC2 instance. Let me know if you need further assistance!
