POC AWS SQS - Simple QRCode Generator

This repository is intended to serve as a proof of concept for AWS SQS implemented in nodejs. In this implementation I tried to exercise all my personal knowledge (still superficial) related to the AWS SQS solution.

Installation

• Navigate to the frontend folder and type => npm install
• Navigate to the backend folder and type => npm install

How to set up the frontend application

• Navigate to the frontend folder and create a file named .env
• Into that folder set values for the following keys

AWS_QUEUE_URL=your-aws-queue-url

AWS_QUEUE_REGION=your-sqs-region

How to set up the backend application

• Navigate to the backend folder and create a file named .env
• Into that folder set values for the following keys

AWS_QUEUE_URL=your-aws-queue-url

AWS_QUEUE_REGION=your-sqs-region

AWS_QUEUE_MAX_NUMBER_OF_MESSAGES=10

AWS_QUEUE_WAIT_TIME_SECONDS=5

Start the frontend application

• node server.js

Start the backend application

• node processor.js

How to test

• Considering that both applications are running
• Open a browser and type http://localhost:3000/
• Type the amount of qrcodes you want to generate
• With the terminal open in the backend application, see the messages being received from SQS
• Open the qrcodes folder in the backend application and open the generated images

Screenshots

• Showing received messages in AWS SQS

• Processing messages from AWS SQS
