JavaScript How Can I Convert Relative URLs Into Absolute URLs When Scraping Web Pages?

Hello everyone.

I am building a web scraper that extracts links from various websites but many pages return relative URLs like "/about" or "../contact" instead of full absolute URLs. I need to reliably convert these into complete URLs including the correct protocol and domain before storing them in my database.

I am using Python with BeautifulSoup and requests but I am struggling to handle edge cases like protocol relative URLs and deeply nested relative paths. Is there a built in Python library that handles this conversion accurately?

What is the safest and most robust approach to resolving relative URLs against a base URL?
