HealthHub - Doctor Appointment & AI Health Assistant

HealthHub is a web application where users can:

• Use an AI-powered assistant (powered by Cohere AI) to get health tips, precautions, and suggested medications based on their symptoms or current feelings

This project is divided into two parts:

• api – The backend server (Node.js, Express, MongoDB, JWT Authentication)
• client – The frontend (React.js)

• Node.js
• npm (comes with Node.js)
• A running MongoDB database (local or cloud like MongoDB Atlas)
• A Cohere AI API key

---

🔑 Environment Setup

Create a .env file inside the api folder and add the following variables:

MONGO_URL=your_mongodb_connection_string  
COHERE_API_KEY=your_cohere_api_key  
JWT_SECRET=your_jwt_secret_key  
PORT=8000  

---

📦 Installation

Run the following commands to set up both api and client folders:

# Go to the backend folder  
cd api  
npm install  

# In a new terminal, go to the frontend folder  
cd ../client  
npm install  

---

💻 Running the Project

Run both backend and frontend in development mode:

# Start the backend  
cd api  
npm run dev  

# Start the frontend in a separate terminal  
cd client  
npm run dev  

Now visit:

• Frontend: http://localhost:3000
• Backend: http://localhost:8000

🤖 AI Assistant

Powered by the Cohere API, the assistant accepts user input like:

"I have a headache and feel dizzy"

And responds with:

• General advice
• Suggested medicines
• Self-care tips

This logic is implemented in the backend, which calls the Cohere API and returns structured output to the frontend.
