Clone this repository:\n   ```bash\n   git clone https://github.com/Taiizor/goCrawler.git\n   cd goCrawler\n   ```\n\n2. Build the application:\n   ```bash\n   go build -o goCrawler\n   ```\n\n## Usage\n\nRun the crawler with the following command:\n\n```bash\n./goCrawler -url \"https://www.vegalya.com\" -depth 3 -workers 10 -output results.json\n```\n\n### Command Line Flags\n\n| Flag | Description | Default |\n|------|-------------|---------|\n| `-depth` | Maximum crawling depth | 2 |\n| `-timeout` | HTTP request timeout | 10s |\n| `-rate` | Rate limit between requests | 100ms |\n| `-workers` | Number of concurrent workers | 5 |\n| `-url` | Starting URL for crawling | (required) |\n| `-output` | Output file name (CSV or JSON) | results.json |\n\n## Examples\n\nCrawl a website with 10 workers to a depth of 3, saving output as JSON:\n```bash\n./goCrawler -url \"https://www.vegalya.com\" -depth 3 -workers 10 -output results.json\n```\n\nCrawl a website and save results as CSV:\n```bash\n./goCrawler -url \"https://www.vegalya.com\" -output results.csv\n```\n\nCrawl with custom timeout and rate limiting:\n```bash\n./goCrawler -url \"https://www.vegalya.com\" -timeout 5s -rate 200ms\n```\n\n## Output Format\n\n### JSON Output\n\nThe JSON output contains:\n- `results`: Array of crawled pages\n- `count`: Number of pages crawled\n- `timestamp`: When the crawl completed\n\nEach page result includes:\n- `title`: Page title\n- `url`: The page URL\n- `status_code`: HTTP status code\n- `depth`: Crawl depth of this page\n- `links`: Array of links found on the page\n- `timestamp`: When this page was crawled\n- `content_length`: Content length in bytes\n\n### CSV Output\n\nThe CSV output contains one row per page with columns:\n- URL\n- Title\n- Depth\n- Timestamp\n- StatusCode\n- ContentLength\n- LinksCount (number of links found)\n\n## License\n\nMIT\n\n## Contributing\n\nContributions are welcome!
