# Crawlshot

A Laravel web crawling and screenshot service with dual deployment options:

1. **Standalone API Service** - Full Laravel application with REST API endpoints
2. **Laravel Package** - HTTP client package for use in other Laravel applications

## Architecture Overview

### Standalone API Service
The main Laravel application provides a complete web crawling and screenshot service:

- **Spatie Browsershot Integration** - Uses Puppeteer for browser automation
- **EasyList Ad Blocking** - Automatic ad/tracker blocking using EasyList filters  
- **Queue Processing** - Laravel Horizon for async job processing
- **24-hour Cleanup** - Automatic file and database cleanup
- **Sanctum Authentication** - API token-based authentication
- **SQLite Database** - Stores job metadata and processing status

### Laravel Package
Simple HTTP client package that provides a clean interface to the API:

- **8 Methods for 8 APIs** - Direct 1:1 mapping to REST endpoints
- **Facade Support** - Clean Laravel integration
- **Auto-discovery** - Automatic service provider registration

## Deployment Options

### Option 1: Standalone API Service

Deploy as a complete Laravel application:

```bash
git clone [repository]
cd crawlshot
composer install
npm install puppeteer
php artisan migrate
php artisan serve
```

**API Endpoints:**
- `POST /api/crawl` - Create HTML crawl job
- `GET /api/crawl/{uuid}` - Get crawl status/result  
- `GET /api/crawl` - List all crawl jobs
- `POST /api/shot` - Create screenshot job
- `GET /api/shot/{uuid}` - Get screenshot status/result
- `GET /api/shot/{uuid}/download` - Download screenshot file
- `GET /api/shot` - List all screenshot jobs
- `GET /api/health` - Health check

**Example API Usage:**
```bash
# Create crawl job
curl -X POST "https://crawlshot.test/api/crawl" \
     -H "Authorization: Bearer {token}" \
     -H "Content-Type: application/json" \
     -d '{"url": "https://example.com", "block_ads": true}'

# Check status  
curl -H "Authorization: Bearer {token}" \
     "https://crawlshot.test/api/crawl/{uuid}"
```

### Option 2: Laravel Package

Install as a package in your Laravel application:

```bash
composer require crawlshot/laravel
php artisan vendor:publish --tag=crawlshot-config
```

**Configuration:**
```env
CRAWLSHOT_BASE_URL=https://your-crawlshot-api.com
CRAWLSHOT_TOKEN=your-sanctum-token
```

**Package Usage:**
```php
use Crawlshot\Laravel\Facades\Crawlshot;

// Create crawl job
$response = Crawlshot::createCrawl('https://example.com', [
    'block_ads' => true,
    'timeout' => 30
]);

// Check status
$status = Crawlshot::getCrawlStatus($response['uuid']);

// Create screenshot
$response = Crawlshot::createShot('https://example.com', [
    'format' => 'jpg',
    'width' => 1920,
    'height' => 1080
]);

// Download screenshot
$imageData = Crawlshot::downloadShot($response['uuid']);
file_put_contents('screenshot.jpg', $imageData);
```
