# Mind Haven Backend API **Separate Express.js Backend for Mind Haven Mental Wellness Platform** ## 🏗️ Tech Stack - **Runtime:** Node.js - **Framework:** Express.js - **Database:** MongoDB Atlas - **Authentication:** JWT (JSON Web Tokens) - **Password Hashing:** bcryptjs - **Language:** JavaScript (ES6+) --- ## 📁 Project Structure ``` mind_haven_backend/ ├── server.js # Main server file ├── .env # Environment variables ├── package.json # Dependencies └── src/ ├── config/ │ └── database.js # MongoDB connection ├── models/ │ ├── User.js # User model │ └── Doctor.js # Doctor model ├── middleware/ │ └── auth.js # Authentication middleware ├── routes/ │ ├── auth.js # Authentication routes │ └── doctors.js # Doctor routes └── utils/ └── jwt.js # JWT utilities ``` --- ## 🚀 Getting Started ### 1. Install Dependencies ```bash npm install ``` ### 2. Configure Environment The `.env` file is already set up with your MongoDB credentials: ```env PORT=5000 MONGODB_URI=mongodb+srv://dulanjanassd_db_user:DR34KJpVUzN0QvYd@cluster0.txkquae.mongodb.net/mind_haven JWT_SECRET=your-super-secret-jwt-key-change-this-in-production-2026 JWT_EXPIRE=7d FRONTEND_URL=http://localhost:3000 ``` ### 3. Run the Server **Development (with auto-restart):** ```bash npm run dev ``` **Production:** ```bash npm start ``` Server will run on: **http://localhost:5000** --- ## ☁️ Deploy on Render ### Option 1: Blueprint (recommended) 1. Push this backend folder to GitHub. 2. In Render, create a new Blueprint service and select the repo. 3. Render will detect `render.yaml` automatically. 4. Set these required env vars in Render: - `MONGODB_URI` - `JWT_SECRET` - `FRONTEND_URL` (use your frontend URL, or multiple URLs separated by commas) ### Option 2: Manual Web Service - Environment: `Node` - Build command: `npm install` - Start command: `npm start` - Health check path: `/api/health` ### Render Notes - `PORT` is provided by Render automatically (default `10000` in `render.yaml`). - CORS supports multiple frontend URLs via comma-separated `FRONTEND_URL`. - Root endpoint `/` and `/api/health` are available for quick service checks. --- ## 📍 API Endpoints ### Authentication Routes (`/api/auth`) | Method | Endpoint | Access | Description | | ------ | ------------------ | ------- | ----------------- | | POST | `/api/auth/signup` | Public | Register new user | | POST | `/api/auth/login` | Public | Login user | | GET | `/api/auth/me` | Private | Get current user | ### Doctor Routes (`/api/doctors`) | Method | Endpoint | Access | Description | | ------ | ---------------------- | ---------------- | ------------------------------ | | GET | `/api/doctors` | Public | Get all doctors (with filters) | | GET | `/api/doctors/:id` | Public | Get single doctor | | GET | `/api/doctors/profile` | Private (Doctor) | Get own profile | | PUT | `/api/doctors/profile` | Private (Doctor) | Update own profile | ### Test Routes | Method | Endpoint | Access | Description | | ------ | ------------- | ------ | ------------------- | | GET | `/api/test` | Public | Test API is running | | GET | `/api/health` | Public | Health check | --- ## 🧪 Testing the API ### 1. Test Server is Running ```bash curl http://localhost:5000/api/test ``` ### 2. Register a User ```bash curl -X POST http://localhost:5000/api/auth/signup \ -H "Content-Type: application/json" \ -d "{\"email\":\"test@example.com\",\"password\":\"password123\",\"name\":\"Test User\",\"userType\":\"user\"}" ``` ### 3. Login ```bash curl -X POST http://localhost:5000/api/auth/login \ -H "Content-Type: application/json" \ -d "{\"email\":\"test@example.com\",\"password\":\"password123\"}" ``` **Save the token from the response!** ### 4. Get Current User (Protected) ```bash curl http://localhost:5000/api/auth/me \ -H "Authorization: Bearer YOUR_TOKEN_HERE" ``` ### 5. Get All Doctors ```bash curl http://localhost:5000/api/doctors ``` --- ## 🔐 Authentication This API uses **JWT (JSON Web Tokens)** for authentication. After login/signup, you'll receive a token. Include it in requests: ``` Authorization: Bearer <your-token> ``` **Token expiration:** 7 days --- ## 📊 Database **MongoDB Atlas:** - Database: `mind_haven` - Collections: `users`, `doctors` **Models:** - **User:** Email, password (hashed), name, userType, profile info - **Doctor:** Professional details, linked to User via `userId` --- ## 🔧 Frontend Integration Update your frontend API service to point to: ```javascript const API_BASE_URL = "http://localhost:5000"; ``` Example fetch: ```javascript const response = await fetch("http://localhost:5000/api/auth/login", { method: "POST", headers: { "Content-Type": "application/json", }, body: JSON.stringify({ email, password }), }); ``` --- ## 📝 Environment Variables | Variable | Description | Default | | -------------- | ------------------------------------ | --------------------- | | `PORT` | Server port | 5000 | | `MONGODB_URI` | MongoDB connection string | (configured) | | `JWT_SECRET` | Secret for JWT signing | (configured) | | `JWT_EXPIRE` | Token expiration time | 7d | | `FRONTEND_URL` | Frontend URL for CORS | http://localhost:3000 | | `NODE_ENV` | Environment (development/production) | development | --- ## 🎯 Features ✅ User authentication (signup/login) ✅ Password hashing with bcrypt ✅ JWT-based authorization ✅ Role-based access control (user/doctor) ✅ Doctor profile management ✅ Doctor listing with filters ✅ MongoDB integration ✅ CORS enabled ✅ Security headers (Helmet) ✅ Request logging (Morgan) ✅ Error handling --- ## 🛡️ Security - Passwords hashed with bcrypt (10 salt rounds) - JWT tokens for stateless authentication - CORS protection - Helmet security headers - Environment variables for sensitive data - Input validation --- ## 📦 Dependencies ### Production - `express` - Web framework - `mongoose` - MongoDB ODM - `bcryptjs` - Password hashing - `jsonwebtoken` - JWT authentication - `cors` - CORS middleware - `helmet` - Security headers - `morgan` - HTTP request logger - `dotenv` - Environment variables - `express-validator` - Input validation - `cookie-parser` - Cookie parsing ### Development - `nodemon` - Auto-restart on file changes --- ## 🚨 Troubleshooting **Port already in use:** ```bash # Windows netstat -ano | findstr :5000 taskkill /PID <PID> /F # OR change PORT in .env ``` **MongoDB connection error:** - Verify internet connection - Check MongoDB URI in `.env` - Ensure IP is whitelisted in MongoDB Atlas **CORS errors:** - Verify `FRONTEND_URL` in `.env` matches your frontend URL - Check browser console for specific CORS message --- ## 📚 Documentation - [Express.js Docs](https://expressjs.com/) - [Mongoose Docs](https://mongoosejs.com/) - [JWT Docs](https://jwt.io/) --- ## ✨ Status ✅ **Ready for Production** **Last Updated:** 2026-01-29 **Version:** 1.0.0 **Port:** 5000 --- **Happy Coding! 🚀**
