How to scrape and extract hyperlink networks with BeautifulSoup and NetworkX

This breaks with using standard web scraping methods (non-headless JS engines). Had to deal with this issue recently due to everything being a damn SPA now. Look into Selenium for running headless browsers if looking to scrape the modern web.

I know some people think all scraping is bad or malicious. I'd like to point out this is a perfectly legitimate use case for it, in fact this is how Google Search operates.

Web scraping done correctly should be barely noticeable if at all to the operators. Don't send 10,000 req/s, have aggressive delays, make your retries extremely generous, try to avoid pages or actions you know are "heavy". You don't need to update data from every product page every 5 minutes.

I wrote a similar Python library to do Beautiful Soup scraping with basic PageRank and a Flask web app: https://github.com/argosopentech/argos-search
