Parsing a site running on websockets?

Question

Parsing

Hello.
There is a site - the front on JS, the exchange of information with the backend takes place via web sockets. It is necessary to write a parser that will receive information on behalf of the user on this site in real time.
I have never encountered real-time parsing of such resources before, can someone tell me which way to look?
Thanks in advance.

Answer 1

aiohttp (client) can connect via websockets.

Answer 2

phantomjs is basically a console browser.
Will be able to execute js and take a screenshot of the site, or access its dom tree at any time after the page is loaded.
I would call it a heavy but absolutely universal way.
