Library for Rapid (Web) Crawler and Scraper Development

This library provides kind of a framework and a lot of ready to use, so-called steps, that you can use as building blocks, to build your own crawlers and scrapers with.

To give you an overview, here's a list of things that it helps you with:

• Crawler Politeness 😇 (respecting robots.txt, throttling,...)
• Load URLs using
  • a (PSR-18) HTTP client (default is of course Guzzle)
  • or a headless browser (chrome) to get source after Javascript execution
• Get absolute links from HTML documents 🔗
• Get sitemaps from robots.txt and get all URLs from those sitemaps
• Crawl (load) all pages of a website 🕷
• Use cookies (or don't) 🍪
• Use any HTTP methods (GET, POST,...) and send any headers or body
• Easily iterate over paginated list pages 🔁
• Extract data from:
  • HTML and also XML (using CSS selectors or XPath queries)
  • JSON (using dot notation)
  • CSV (map columns)
• Extract schema.org structured data in JSON-LD format from HTML documents
• Keep memory usage low by using PHP Generators 💪
• Cache HTTP responses during development, so you don't have to load pages again and again after every code change
• Get logs about what your crawler is doing (accepts any PSR-3 LoggerInterface)
• And a lot more...
