Doctor Appointment Booking System (Minimal)

This is a minimal full-stack Flask application implementing:

• User registration/login (patient, doctor, admin)
• Doctor profiles with available time slots
• Patients can book appointments; overlapping slots are prevented
• Simulated Razorpay payment flow (placeholder for real integration)
• Email/SMS placeholders (configure SMTP or Twilio)
• SQLite database via SQLAlchemy
• Jinja2 templates for frontend

Run locally

1. Create virtualenv and install requirements: python -m venv venv source venv/bin/activate # on Windows: venv\Scripts\activate pip install -r requirements.txt

2. Set environment variables (create a .env file) - example: FLASK_APP=app.py FLASK_ENV=development SECRET_KEY=replace_this_with_a_secret_key RAZORPAY_KEY_ID=your_key_here RAZORPAY_KEY_SECRET=your_secret_here SMTP_SERVER=smtp.example.com SMTP_PORT=587 SMTP_USER=your_email SMTP_PASS=your_email_password

3. Initialize DB and run: python app.py

   This will create 'app.db' and run the dev server at http://127.0.0.1:5000

Notes

• Razorpay integration is stubbed with a '/pay' endpoint that demonstrates where you'd call Razorpay orders API.
• For production, secure secrets, use HTTPS, and configure a real email/SMS gateway.
