QR-Code Generator

A minimal proof-of-concept (PoC) project that generates QR codes.

This repository contains a small Python backend that produces QR code images and an Angular frontend that demonstrates usage. It is intended as a simple demo — not production-ready.

Repository layout

• backend/ : Python service (server code, requirements). Exposes a simple HTTP endpoint to generate QR codes.
• frontend/ : Angular application that calls the backend and displays generated QR codes.
• docker-compose.yml : Optional convenience to build and run both services together using Docker.

Quick Start (Docker Compose)

1. Build and start both services:

docker compose up --build

2. When containers are running, open the frontend in your browser (the compose file maps ports; commonly http://localhost:4200). The frontend calls the backend to generate QR codes.

Local Development

• Backend (Python):

  • Create a virtual environment, install dependencies, and run the server:

   cd backend
   python -m venv .venv
   source .venv/bin/activate
   pip install -r requirements.txt
   python app/server.py

• Frontend (Angular):

  • Install dependencies and run the dev server:

   cd frontend
   npm install
   npm run start
   # or: npx ng serve

Usage

• Use the frontend UI to enter text/data and request a QR code, or call the backend HTTP endpoint directly to receive a generated QR image (check backend/app/server.py for the exact route).
