+# 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)
+
+## <20> Quick Start
+
+### 1. Start the Database (existing Docker setup)
+```bash
+# From main project directory
+docker-compose up -d
+```
+
+### 2. Start the Node.js Backend
+```bash
+cd backend
+npm install
+npm run build
+node dist/app.js
+```
+
+### 3. Start the React Frontend  
+```bash
+cd frontend
+npm install
+npm run dev
+```
+
+## 📱 Features Implemented
+
+### ✅ Backend API
+- **Health Check** - Server status endpoint
+- **Recipe Management** - Full CRUD operations with search/pagination
+- **Ingredient Management** - CRUD operations for recipe ingredients  
+- **Image Serving** - Static file serving for recipe images
+- **Input Validation** - Joi schema validation
+- **Error Handling** - Centralized error management
+- **Security** - CORS, Helmet, rate limiting, input sanitization
+
+### ✅ Frontend Application
+- **Recipe List** - Grid view with search, filtering, pagination
+- **Responsive Design** - Mobile-first CSS design
+- **Image Display** - Recipe images with fallback handling
+- **Navigation** - Clean header with route navigation
+- **Search & Filter** - Real-time search and category filtering
+- **Error Handling** - User-friendly error messages
+- **Loading States** - Visual feedback for API calls
+
+## 🎯 Current Status
+
+### ✅ **COMPLETED**
+- Node.js backend with TypeScript
+- Prisma ORM with existing database schema
+- Complete REST API for recipes, ingredients, images
+- React frontend with modern UI
+- Database integration working
+- Both servers running successfully
+- API endpoints tested and working
+- Responsive design implemented
+
+### 🔄 **Next Steps**
+1. **Recipe Detail View** - Individual recipe pages
+2. **Recipe Creation/Editing** - Forms for CRUD operations
+3. **Image Upload** - File upload functionality
+4. **Ingredient Management** - Dedicated ingredient pages
+5. **Docker Configuration** - Containerize Node.js stack
+6. **Performance Optimization** - Caching, lazy loading
+7. **Testing** - Unit and integration tests
+
+## 📊 API Endpoints
+
+### Recipes
+- `GET /api/recipes` - List recipes (pagination, search, filter)
+- `GET /api/recipes/:id` - Get single recipe
+- `POST /api/recipes` - Create recipe
+- `PUT /api/recipes/:id` - Update recipe  
+- `DELETE /api/recipes/:id` - Delete recipe
+
+### Ingredients
+- `GET /api/ingredients` - List ingredients
+- `GET /api/ingredients/:id` - Get single ingredient
+- `POST /api/ingredients` - Create ingredient
+- `PUT /api/ingredients/:id` - Update ingredient
+- `DELETE /api/ingredients/:id` - Delete ingredient
+
+### Images
+- `GET /api/images/recipe/:recipeId` - Get recipe images
+- `GET /api/images/serve/:imagePath` - Serve image file
+- `GET /api/images/:id` - Get image metadata
+
+### Health
+- `GET /api/health` - Server health check
+
+## 🔧 Development Commands
+
+### Backend
+```bash
+cd backend
+
+# Development
+npm run dev          # Start with hot reload (if ts-node configured)
+npm run build        # Build TypeScript
+npm start            # Start production server
+node dist/app.js     # Direct node execution
+
+# Database
+npm run db:generate  # Generate Prisma client
+npm run db:push      # Push schema to database
+npm run db:studio    # Open Prisma Studio GUI
+```
+
+### Frontend  
+```bash
+cd frontend
+
+# Development
+npm run dev          # Start Vite dev server
+npm run build        # Build for production
+npm run preview      # Preview production build
+npm run lint         # Run ESLint
+```
+
+## <20> Technology Benefits
+
+### vs. PHP Version
