Get DOM element's actual width using jsdom

Question

I wonder if I could get a DOM element's actual width and coordinates, as I can get using .clientWidth / .offsetWidth from within the browser.

Does jsdom has browser rendering capabilities in order to get this data?

If not, how can I get this within node.js server?

Thanks!

JSDOM is strictly a DOM API emulation library. It does not attempt to actually render a document, which is necessary to compute element size and position.

You may want to look at PhantomJS. It is a full WebKit renderer with a JavaScript API. It is entirely separate from node, so you either need to write a utility script using Phantom's API, or use a npm module that lets you control Phantom from node.
