How to "execute" HTML+Javascript page with Node.js

Question

So, I have my Node.js script. And I have some HTML page which contains HTML with JavaScript (jquery) in it. How can I load it and get result of execution of JavaScript on this page?

If screen scraping is what your after, check out: http://blog.nodejitsu.com/jsdom-jquery-in-5-lines-on-nodejs — Brandon Boone, Mar 07 '11 at 16:56
My HTML page does some manipulations with divs -- and I need to get the result of those manipulations. It's not the screenscrapping to get the source HTML w/ Javascript, but actually the result of their execution. — alexeypro, Mar 07 '11 at 17:15

You can check the zombie.js project : http://zombie.labnotes.org/

It should load the page mostly as in a real browser.

Something like JSDOM should do it.

Right, but can't figure out how to I get not just HTML/JS of the window, but the result of their execution there. – alexeypro Mar 07 '11 at 17:16

Also, a great solution is https://github.com/GoogleChrome/puppeteer. Which is Headless Chrome Node API and maintained by Chrome DevTools team.

But it is very slow at loading pages, while still faster than competitors like Phantom – Manuel Di Iorio Mar 20 '21 at 09:36
