How to parse a node js website?

Question

JavaScript

Actually, I wanted to learn how to parse sites and tried simple sites with them, no problems arose.
As I understand it, the data is loaded there dynamically via websocket
How to parse?)

Answer 1

Connect to a websocket and collect data, for this you need any websocket client and dig the site a little to understand what requests to send.
No browsers are needed for this as they say.

Answer 2

I think Selenium will help you

Answer 3

For the complex, there is a special service apify.com, here you can find a million examples https://apify.com/store?type=acts in short, is it possible to use the built-in pupetter service or throw your dockerfile and collect data from sites in several streams .
In your case, most likely it’s enough just to open the dev tools from the browser, pull out the url and data for connecting to the sockets from there, play around with the data being sent, and you can pull what you need without a browser.
