🚀 Installation & Setup

Follow these steps to run Prepify – Smart Study Assistant locally.

---

🧰 Setup Backend

1. Navigate to the backend folder:

   cd backend

2. Install dependencies:
   ```bash
   npm install

3. Create a .env file inside backend/ and add:

   MONGO_URI=mongodb+srv://<username>:<password>@cluster0.mongodb.net/prepify
   JWT_SECRET=your_jwt_secret_key
   GEMINI_API_KEY=your_google_gemini_api_key
   PORT=5000

   Explanation:

   • MONGO_URI → MongoDB connection string (Atlas/local)
   • JWT_SECRET → Any random secret string for authentication
   • GEMINI_API_KEY → API key from Google AI Studio
   • PORT → Default backend port (5000)

4. Start the backend server:

   npm start

   Or with Nodemon:

   npx nodemon index.js

   ✅ Expected Output:

   Server running on port 5000
   MongoDB connected successfully

💻 Setup Frontend (Client)

1. Open a new terminal (keep backend running) and navigate to:

   cd ../smart-study

2. Install dependencies:

   npm install

3. Start the React development server:

   npm run dev

4. Open your browser and visit:

   http://localhost:5173
   

   ✅ You should now see the Prepify Dashboard login screen.

🔑 Create Default User (Optional)

You can register a user directly via the app’s Register page. Alternatively, insert a test user in MongoDB:

{
  "name": "Aarmee Patel",
  "email": "aarmee@example.com",
  "password": "123456"
}

Then log in using that email and password.

---

🧠 Connecting Backend and Frontend

Your frontend connects by default to:

http://localhost:5000/api

If your backend runs on another port, update the base URL in:

smart-study/src/config.js

Example:

export const BASE_URL = "http://localhost:5000/api";
