Why does JSCAD use the very old version of rollup? By runing

for pf in `find -name 'package.json' | grep -v node_modules`; do echo $pf; grep 'rollup' $pf ; done

I get the version 2.79.1. I don't have problem with old version of a software, as long as it works and I can find the document of the old version.

Let me explain the background why I need to use rollup.
I want to extend the document with embedded running examples. So I make a small static JS-file to use it in each JSDoc generated HTML-files to display example. This static JS file should import the same JS modules in the repository, show I can automatically keep it consistent with versions of JSCAD:

// filename web-render.es.js
import { cameras, commands, controls, entitiesFromSolids, prepareRender } from "@jscad/regl-renderer"

export const render = (shapes, domId) => {
// .... Do something here
}

This file is then converted into web-render.js, which exposes the fuction render into global scope, and can be easily used as

<script src="web-render"></script>
<!--  some where in the doc: -->
<div id="sphere-demo"></div>
<script>
render(model, "sphere-demo")
</script>

My questions:

• Why JSCAD does use the old version of rollup?
• Where can I find the old document of the used rollup version?
• If the document does not exist anymore, how much effort does it take to port the old version to the new of rollup?

@z3dev Yes, I'd like to try the version 3. For me it is very comfortable to use the standard.

@hrgdavor My Model is very simple: One is an extruding, one is a model of H2O with 3 Atoms. I construct them in JavaScript. Principal I am happy with replacement the function demo in the file demo.html with my model. So my task is done. But I'm a software developer, so I'd like to use ES-6 standard import than require.

@z3dev
yes! It works fine for a proof of concept and Nodejs's require(). Now I try to use the modules in manner of ES-6 import by using

// in main.js
import myModelFunction from "myModel.js";
// do setup as in demo.html
// ...

and in myModel.js I would like to use ES-6 import to import @jscad/modeling and @jscad/regl-renderer.
How do you think about it? Is my approach ok or I should only use the Nodejs require()-Function?

Hi there,

I would like to use JSCAD to display 3D Objects in a webpage automatically as soon as the page loaded, without any modification around the objects.

I have read/tried the file packages/web/demo.{html,js}. They are designed as an online IDE, but not as a display-tool.

I have some experience with JavaScript, so for the first help I just need to know where I find example/document so far.

Thanks for response/answer
