# Starting the Application

## Backend Server

Open a terminal and run:

```bash
cd server
npm run dev
```

The backend server should start on `http://localhost:3005`

You should see output like:
```
Server running on port 3005
Connected to database
```

## Frontend Development Server

Open another terminal and run:

```bash
npm run dev
```

The frontend should start on `http://localhost:5173`

## Troubleshooting

### Backend won't start
- Check if port 3005 is already in use: `lsof -ti:3005`
- Check database connection in `server/.env`
- Run `cd server && npm install` to ensure dependencies are installed

### Frontend won't start
- Check if port 5173 is already in use
- Run `npm install` to ensure dependencies are installed
- Check `.env.local` for correct API URL

### "Server returned non-JSON response" error
- This means the backend server is not running
- Start the backend server first (see above)
- Check that `VITE_API_BASE_URL` in `.env.local` matches your backend URL

## Quick Check

Test if backend is running:
```bash
curl http://localhost:3005/api/events
```

Should return JSON with events list.
