Ah, ok. Yes, if you can remote control a browser you can of course "scrape" anything the browser can load. (Although even here the puppeteer README says it can load server side rendered data. Not all single page web apps do that.) To me that isn't quite the same as having a separate program, independent of the browser, that is able to just load the data from the URL and then operate on it, which is what I'm used to seeing referred to as "scraping".

I think what you are suggesting is often done using browser extensions. It's obviously not independent of the browser, but it serves this use case where you want to extend existing apps adding interactive features.

My understanding of the word "scraping" is primarily something related to en mass automated data extraction from user interfaces.
