What are the effective libs for Kotlin and NodeJs for parsing sites with ajax, authorization with SCRF and navigation through personal account pages?

Question

JavaScript

Good afternoon,
How can a script in JS or Kotlin emulate user actions in the browser at the time the page is fully loaded. It is necessary to be able to:
1) authorize in the form
2) walk through the pages closed for the guest
3) interact with DOM elements on these pages - click on the button
4) parse data from blocks.
Considered PhantomJS and CasperJS . But I don't know what they can cover from the list.
For Kotlin , as I understand it, it is rather damp in this respect:

Please advise which set of tools should be chosen for this task?

Answer 1

PhantomJS can definitely cover such cases.
