Description:

In this hands-on project, I demonstrate how to deploy a simple Node.js application to the cloud. This project is ideal for testing basic deployments and understanding the fundamental steps involved in setting up a Node.js app on a server. The guide covers the installation of Node.js and npm using nvm, setting up Git, cloning the repository, and running the application.

Here's Step by Step Guide:

Step 1: Launch an EC2 Instance with a Ubuntu OS and necessary requirements and specified ports.

Step 2: Connect the Instance with EC2 Instance Connect.

Step 3: Install NodeJS and NPM using nvm

sudo su -
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.34.0/install.sh | bash

Step 4: Install Node.js and Verify Installation.

nvm install node
node -v
npm -v

Step 5: Install the git and clone the repository.

apt-get update -y
apt-get install git -y
git clone https://github.com/Lokeshwar-Rajan/nodejs-on-ec2.git

Step 6: And then install the necessary packages and start the application.

npm install
npm start

Step 7: Now copy the public IPv4 and Test the sample node.js app.

Building a Serverless File Sharing Platform

DESCRIPTION:

I built a Serverless File Sharing Platform that enables users to securely upload and download files through a straightforward HTTP API. This platform uses AWS Lambda for serverless compute, API Gateway for managing RESTful APIs, and Amazon S3 for scalable and durable object storage.

ARCHITECTURE:

Here's Step by Step Guide:

Step 1 : Create an S3 bucket to store uploaded files
Step 2 : Create Upload and Download Lambda Functions with required
execution role with necessary IAM Role for S3.
Step 3 : Create an API Gateway with POST and GET Methods and integrate
it with the lambda functions
Step 4 : Configure GET Method

{
  "queryStringParameters": {
      "fileName": "$input.params('fileName')"
  }
}

Step 5 : Configure POST Method

{
  "body" : "$input.body",
  "queryStringParameters" : {
      "fileName" : "$input.params('fileName')"
  }
}

Step 6 : Now Deploy the API and Test the application using a third party
client such as Postman etc.

Proof Of Concept:

As this is my first post here I'm very excited and curious to explore many more stuffs and grow together as a community.
