Thanks.
What I really want is to use JavaScript PARI/GP in a JSCAD code, like 
the code you see on right:

https://jscad.app

So I need to run gp-sta.js in node, not in browser.
gp-sta.js has no export, so require does not work.
But "import" does.
But import does not allow to import with "http:" or "https:" out of the 
box.
But with "--experimental-network-imports"
https://h3manth.com/posts/HTTP-imports-node/
use of "http:" states that "https:" is needed for non-local addresses 
like
http://pari.math.u-bordeaux.fr/gpjswasm/gp-sta.js
so still work in progress.

But what is amazing is that local gp-sta.js PARI/GP runs in node 
already(!!), see below.

Regards,

Hermann.


As stated import works, but node told me that "await import(...)" has to 
be used.
