Crawl all links on website

This example uses the enqueue_links helper to add new links to the RequestQueue as the crawler navigates from page to page. By automatically discovering and enqueuing all links on a given page, the crawler can systematically scrape an entire website. This approach is ideal for web scraping tasks where you need to collect data from multiple interconnected pages.

tip

If no options are given, by default the method will only add links that are under the same subdomain. This behavior can be controlled with the strategy option, which is an instance of the EnqueueStrategy enum. You can find more info about this option in the Crawl website with relative links example.
