node.js - Is it possible to create a web crawler that would work for every website?

Question

I probably already know the answer to this question but just to be 100% sure, is it possible to make a web crawler that could work for any website the user might enter?

I have made a web crawler for a client on MERN stack for a pharmacy site, that crawls 2 different websites and retrieve information such as title, formula, manufacturer etc of a searched medicine and save it in the database. This works fine. But now the client wants to add an option that allows users to add website links and the web crawler would crawl that website and scrape the results from there.
