+# TuteDude Hackathon Backend
+
+A complete Node.js backend API for a vendor-supplier platform, designed to work with the frontend at [https://github.com/morningstarxcdcode/F](https://github.com/morningstarxcdcode/F).
+
+## 🚀 Features
+
+### ✅ Complete API Implementation
+- **User Authentication** - Registration, login, profile management with JWT
+- **Product/Inventory Management** - CRUD operations for products with categories and stock
+- **Order Management** - Order creation, tracking, status updates (pending/delivered/cancelled)
+- **Supplier/Seller Management** - Seller profiles, reviews, and business management
+- **Buyer Features** - Wishlist, order history, recommendations, statistics
+
+### 🎯 Frontend Compatibility
+- **Authentication Endpoints** - `/api/auth/*` for login/register
+- **Inventory Endpoints** - `/api/inventory/*` for product management
+- **Order Endpoints** - `/api/orders/*` for order operations
+- **Supplier Endpoints** - `/api/suppliers/*` for supplier management
+
+### 🔧 Technical Stack
+- **Node.js** with Express.js framework
+- **MongoDB** with Mongoose ODM
+- **JWT** authentication with refresh tokens
+- **Bcrypt** for password hashing
+- **Cloudinary** integration for file uploads
+- **CORS** enabled for frontend integration

+
+## 📋 API Endpoints
+
+### Authentication (`/api/auth` or `/api/user`)
+- `POST /api/auth/register` - User registration
+- `POST /api/auth/login` - User login
+- `POST /api/auth/logout` - User logout
+- `GET /api/auth/profile` - Get current user profile
+- `PUT /api/auth/update` - Update user details
+- `POST /api/auth/refreshaccesstoken` - Refresh access token
+
+### Inventory Management (`/api/inventory` or `/api/product`)
+- `GET /api/inventory` - Get all products (with pagination, filtering)
+- `POST /api/inventory` - Create new product
+- `GET /api/inventory/:productId` - Get product by ID
+- `PUT /api/inventory/:productId` - Update product
+- `DELETE /api/inventory/:productId` - Delete product
+- `GET /api/inventory/search` - Search products
+- `PUT /api/inventory/:productId/stock` - Update stock levels
+
+### Order Management (`/api/orders` or `/api/order`)
+- `GET /api/orders` - Get all orders
+- `POST /api/orders` - Create new order
+- `GET /api/orders/:orderId` - Get order by ID
+- `PUT /api/orders/:orderId` - Update order status
+- `PUT /api/orders/:orderId/cancel` - Cancel order
+- `PUT /api/orders/:orderId/deliver` - Mark as delivered
+- `GET /api/orders/buyer/:buyerId` - Get orders by buyer
+- `GET /api/orders/seller/:sellerId` - Get orders by seller
+- `GET /api/orders/stats` - Get order statistics
+
+### Supplier Management (`/api/suppliers` or `/api/seller`)
+- `GET /api/suppliers` - Get all suppliers
+- `POST /api/suppliers` - Create new supplier
+- `GET /api/suppliers/:sellerId` - Get supplier by ID
+- `PUT /api/suppliers/:sellerId` - Update supplier

+
+## 🔐 Authentication
+
+The API uses JWT-based authentication:
+1. Register or login to receive access and refresh tokens
+2. Include the access token in the `Authorization` header: `Bearer <token>`
+3. Use refresh token to get new access tokens when expired
+
+## 📊 Data Models
+
+### User/Buyer
+- Shop name, role (SELLER/BUYER), phone, email, full name
+- Profile images (avatar, cover) via Cloudinary
+- Encrypted passwords with bcrypt
+
+### Product
+- Name, description, price, category, stock amount
+- Associated with seller, timestamps
+
+### Order
+- Buyer, seller, product references
+- Status tracking (cancelled, delivered)
+- Automatic stock management
+
+### Seller/Supplier
+- Shop details, owner information
+- Contact details, address
+- Review count and ratings
+
+## 🧪 Testing
+
+The server includes health check endpoints:
+- `GET /` - API information and available endpoints
+- `GET /api/health` - Server status check
+
+Example test:
+```bash
+curl http://localhost:8000/api/health
+# Response: {"status":"OK","timestamp":"2025-07-27T08:10:54.932Z"}
+```
+
+## 🌐 Frontend Integration
+
+This backend is designed to work seamlessly with the frontend available at:
+[https://github.com/morningstarxcdcode/F](https://github.com/morningstarxcdcode/F)
+
+The frontend expects these exact endpoint patterns, which are all implemented:
+- Authentication routes for login/register
+- Inventory management for products
+- Order management for tracking
+- Supplier network management
+
+## 🚀 Production Deployment
+
+1. Set up MongoDB database (local or cloud)
+2. Configure environment variables
+3. Set up Cloudinary for file uploads
+4. Configure CORS for your frontend domain
+5. Use PM2 or similar for process management
+6. Set up reverse proxy (nginx)
+7. Configure SSL certificates
+
+## 📝 Development Notes
+
+- Server can start without database connection for development
+- All routes are protected except registration and login
+- Comprehensive error handling and validation
+- Pagination and filtering support on list endpoints
+- Automatic stock management on orders
