Modern Recipe Management System

A complete modern web application built with Node.js, TypeScript, React, and MySQL - a modern alternative to the existing PHP application.

🚀 Architecture Overview

Backend (Node.js + TypeScript)

• Express.js REST API server
• Prisma ORM for type-safe database access
• TypeScript for development safety
• MySQL database (shared with PHP version)
• Security middleware (Helmet, CORS, rate limiting)

Frontend (React + TypeScript)

• React 18 with functional components and hooks
• TypeScript for type safety
• Vite for fast development and building
• React Router for client-side routing
• Axios for API communication
• Modern CSS with responsive design

Database

• MySQL 8.0 (same database as PHP version)
• Prisma schema mapped to existing tables
• Compatible with current PHP application

🌐 Live URLs

• React Frontend: http://localhost:5173
• Node.js API: http://localhost:3001
• PHP Application: http://localhost:8082 (when Docker is running)
• phpMyAdmin: http://localhost:8083 (when Docker is running)

<EFBFBD> Quick Start

1. Start the Database (existing Docker setup)

# From main project directory
docker-compose up -d

2. Start the Node.js Backend

cd backend
npm install
npm run build
node dist/app.js

3. Start the React Frontend

cd frontend
npm install
npm run dev
