Error: require() of ES Module is not supported

[pcace]

Hi,

i am trying to get your library to run in nodejs, but i am stuck importing it correctly. is the problem on my side or is something broken with the library? this is the errormessage:

Error: require() of ES Module C:\Users\user\Documents\citygmlToGltf\node_modules\citygml-to-3dtiles\src\Converter.mjs not supported.
Instead change the require of C:\Users\user\Documents\citygmlToGltf\node_modules\citygml-to-3dtiles\src\Converter.mjs to a dynamic import() which is available in all CommonJS modules.       

when having this in my app.ts:

import Converter from "citygml-to-3dtiles";
  let converter = new Converter();

(i also had to add a citygml-to-3dtiles.d.ts in node-module/@types)
and added "type" : "module", to the package.json of the module... with no luck

any idea what i am doing wrong here?

Thanks a lot!

What's your NodeJS version?
It seems you're using Typescript. Can you try without Typescript, does that work?

The error message suggests using dynamic import, have you tried that? I don't have experience with it, so can't suggest exact syntax.

hi, my Node.js is v16.14.2.
i will give it a try, but i need to be in TS environment :/

I'm not too knowledgeable about JS modules/import. But it looks to me like the module/file from which you import citygml-to-3dtiles from doesn't support the type of import you're using (the one from this repo's readme). I'd try the dynamic import instead.
