# Price Tracker - Docker Deployment Guide

## 🚀 Quick Start

This is a complete price tracking system with:
- Product management (Add/Edit/Remove products)
- Specification-based alert profiles (e.g., "any 6TB harddrive under 500 DKK")
- Discord webhook notifications
- No login required

## Prerequisites

- Docker and Docker Compose installed
- A Discord webhook URL (optional, for notifications)

## Installation

### 1. Clone the repository

```bash
git clone <your-repo-url>
cd <repo-name>
```

### 2. Build and run with Docker Compose

```bash
docker-compose up -d
```

The application will be available at: **http://localhost:8183**

### 3. Stop the application

```bash
docker-compose down
```

## How It Works

### Product Management
1. Go to **Products** tab
2. Click "Add Product"
3. Enter:
   - Product name and URL
   - Store (Proshop, Komplett, Amazon)
   - Category (Hard Drive, RAM, Processor, Graphics Card)
   - Current price
   - Specifications (size, type, brand)

### Alert Profiles (Specification-Based)

Instead of tracking specific products, you create profiles based on what you need:

**Example**: "I need any 6TB harddrive under 500 DKK"

1. Go to **Alerts** tab
2. Click "Add Alert Profile"
3. Configure:
   - Profile name: "6TB Storage Deal"
   - Category: Hard Drive
   - Target price: 500 DKK
   - Minimum size: 6TB
   - Type: SSD (optional)
   - Discord webhook URL (optional)

### Discord Notifications

To receive Discord notifications:

1. In Discord, go to Server Settings → Integrations → Webhooks
2. Create a new webhook
3. Copy the webhook URL
4. Paste it in your alert profile

When a product matches your criteria and is below your target price, you'll get a Discord message!

### Checking Prices

Click the "Check Prices Now" button in the Alerts tab to manually trigger price checks.

**Automated Checks**: Set up a cron job to call the check-prices endpoint:

```bash
# Check prices every hour
0 * * * * curl -X POST http://localhost:8183/functions/v1/check-prices
```

## Architecture

```
Frontend (React + Vite)
    ↓
Lovable Cloud Backend
    ↓
PostgreSQL Database
    ↓
Discord Webhooks
```

### Database Tables:
- **products**: All tracked products with specifications
- **alert_profiles**: Specification-based alert configurations
- **price_history**: Historical price data
- **alerts_log**: Log of triggered alerts

### Backend Functions:
- **check-prices**: Matches products to alert profiles and triggers notifications
- **send-discord-alert**: Sends formatted alerts to Discord

## Configuration

### Environment Variables

The app uses Lovable Cloud which is pre-configured. No additional environment setup needed!

### Port Configuration

Default port is 8183. To change it, edit `nginx.conf`:

```nginx
listen YOUR_PORT;
```

## Development

### Local Development (without Docker)

```bash
npm install
npm run dev
```

### Building for Production

```bash
npm run build
```

## Troubleshooting

### Can't see products or alerts
- Check browser console for errors
- Verify Lovable Cloud is connected
- Check database tables in Cloud tab

### Discord notifications not working
- Verify webhook URL is correct
- Check edge function logs in Cloud tab
- Test webhook manually with curl

### Docker build fails
- Clear Docker cache: `docker-compose build --no-cache`
- Check Docker logs: `docker-compose logs`

## Features

✅ Product CRUD operations
✅ Specification-based alerts (not tied to specific products)
✅ Discord webhook integration
✅ No authentication required
✅ Real-time price tracking
✅ Dashboard with statistics
✅ Single Docker deployment

## Example Alert Scenarios

1. **Budget Storage**: "Any 6TB+ harddrive under 450 DKK"
2. **RAM Upgrade**: "32GB+ DDR5 RAM under 900 DKK"
3. **GPU Deal**: "Any RTX 4070 graphics card under 4000 DKK"
4. **Fast Storage**: "2TB+ NVMe SSD under 1000 DKK"

Each alert will match ANY product that meets your specifications!
