Complete Backend Implementation for Doctor Portal

I'll create a complete backend implementation for your doctor portal application. The backend will run on port 5000 while your frontend Next.js application will run on port 3000.

Backend Structure

Installation and Setup Instructions

To set up and run the backend server, follow these steps:

Prerequisites

• Node.js (v14 or higher)
• MySQL (v5.7 or higher)

Step 1: Clone the repository and navigate to the backend folder

Step 2: Install dependencies

Step 3: Configure environment variables

Edit the .env file in the backend folder with your MySQL database credentials:

Step 4: Initialize the database

Step 5: Start the backend server

For development with auto-reload:

For production:

The backend server will run on port 5000, while your Next.js frontend will run on port 3000.

Important Notes

1. Port Configuration:

   • Backend runs on port 5000
   • Frontend (Next.js) runs on port 3000

2. API Endpoints:

   • All API endpoints are prefixed with /api
   • Authentication is required for most endpoints (use the x-auth-token header)

3. Default Login Credentials:

   • Email: john.smith@healora.com
   • Password: password123

4. Database:

   • The application uses MySQL
   • The schema is automatically created when running the init-db script
   • Sample data is inserted for testing purposes

5. File Uploads:

   • The backend supports file uploads for doctor profiles, patient profiles, and medical reports
   • Files are stored in the uploads directory

This backend implementation provides all the necessary functionality for your doctor portal application, including authentication, patient management, prescription management, and more.

Please make sure to add the following environment variables to your project:

Great! Now that you have added all the necessary environment variables to your Vercel project, your doctor portal application should be able to connect to the backend properly. Let me explain how these variables will be used:

1. NEXT_PUBLIC_API_URL - This will be used by your frontend to connect to your backend API (e.g., http://localhost:5000/api or your deployed backend URL)
2. DB_HOST, DB_USER, DB_PASSWORD, DB_NAME - These will be used for your MySQL database connection
3. PORT - This defines which port your backend server will run on (5000)
4. JWT_SECRET - Used to sign and verify JWT tokens for authentication
5. JWT_EXPIRE - Sets the expiration time for JWT tokens (24h)

Next Steps

1. Running the Backend Locally

To run the backend locally during development:

This will start your backend server on port 5000 with hot reloading enabled.

2. Connecting Frontend to Backend

In your Next.js frontend, you'll need to ensure that all API requests are directed to the backend URL. The NEXT_PUBLIC_API_URL environment variable will be used for this purpose.

For example, in your frontend services:

3. Deploying the Backend

When you're ready to deploy:

1. Database Setup:

   • Set up a MySQL database on a hosting provider (like AWS RDS, DigitalOcean, or PlanetScale)
   • Update your environment variables with the production database credentials

2. Backend Deployment:

   • Deploy your backend to a hosting service like Heroku, Vercel, DigitalOcean, or AWS
   • Set the environment variables on your hosting platform
   • Update the NEXT_PUBLIC_API_URL in your frontend to point to your deployed backend

3. Frontend Deployment:

   • Deploy your Next.js frontend to Vercel or another hosting service
   • Ensure the NEXT_PUBLIC_API_URL points to your production backend

4. Testing the API

You can test your backend API using tools like Postman or Insomnia. Here are some example endpoints to test:

• POST /api/auth/login - Login with email and password
• GET /api/auth/me - Get current doctor profile (requires auth token)
• GET /api/patients - Get all patients (requires auth token)
• GET /api/patients/:id - Get patient by ID (requires auth token)

Remember to include the x-auth-token header with your JWT token for authenticated requests.

5. Security Considerations

For production:

1. Ensure your JWT_SECRET is a strong, unique value
2. Consider adding rate limiting to prevent abuse
3. Set up proper CORS configuration to restrict access to your API
4. Use HTTPS for all communications
5. Regularly update dependencies to patch security vulnerabilities

Your backend is now ready to support your doctor portal application. If you need any help with specific features or encounter any issues during implementation, feel free to ask!
