You might want to look at Tampermonkey. It depends on how/whether you want to distribute it.

I was wondering if it was possible for a chrome extension to do some light web scraping. In short, what I would like is for my chrome extension to be able to capture the titles of products a person is looking for.

For example, let’s say I am on amazon shopping for cupcakes.

Inspect of title from amazon listing for cupcakes.

I would like to be able to take the title information “365 everyday value cupcakes…” and do something with it in the chrome extension using javascript.

Is this possible?

Everything I search for scraping comes back as an extension that is already developed. I do not want something already developed, I want to program this myself!

Thanks for all of your help!
