Outside of spawn I tried to use JSDOM via "magic functions" and

pulumi up
Previewing update (dev):

                                        it was a native code function.
    
    Function code:
      function get() { [native code] }

Trying to use https://github.com/jsdom/jsdom#convenience-apis fromURL but looks like it calls serialize().

Then I can't execute binaries and I can't write my own code with what look like typical js libraries.
