Question/Requirement invoke jsdom/d3.js using es4x

[rzorzorzo]

Hello,
I have a vertx application (java) where I would like to use d3.js to generate server side svg charts.
I think that polyglot programming makes most sense if one can leverage, out of the box, existing libs.

I tested es4x for this. However this did not work as expected.
I am getting many errors such as "fs module not found" (or similar).
Here the js code:

jsdom = require('jsdom')
d3 = require('d3')

to reproduce create an npm project, then call "npm install --save jsdom d3"
create a file index.js with the above content.
invoke the index.js file with es4x.

I have been able to get this to run with j2v8 nodeJS implementation.
But, es4x would be a better fit for my application, as this would be a pure java application.

As a side note: with graalvm (using the experimental require feature) I am getting the similar errors as with es4x.

Hi Ron,

In seems that d3 is trying to pull node specific modules, perhaps we need to tweak it to "think" it's running on a browser and it should work?

I think I need to prepare such a project and debug where it is calling the filesystem and see if we can avoid it.
