Loading asset data from local files in nodejs

Questions

I noticed my file already imports some kind of loaders package. Trying to import only the loader I wanted didn’t seem to work. After I moved on from that I found extension and the dataurl were the only issues.

Adding extension like above did help! Documentation does not make this clear.
https://doc.babylonjs.com/typedoc/classes/BABYLON.SceneLoader#LoadAssetContainerAsync
Perhaps samples do

Also I had to form the dataurl by hand to get it to load. Node’s createDataURL doesnt seem to work properly here?

import * as BABYLON from "babylonjs";
import "babylonjs-loaders";
import { readFile } from "fs/promises";

// ...

const environmentModel = await readFile(
    "./thelocalfilepath.glb",
  );
  const envFileb64 = Buffer.from(environmentModel).toString("base64");
  const envFileDataURL = "data:model/gltf-binary;base64," + envFileb64;

  console.log("envFileDataURL", envFileDataURL.toString().slice(0, 40));

  const container = await BABYLON.SceneLoader.LoadAssetContainerAsync(
    envFileDataURL,
    undefined,
    scene,
    undefined,
    ".gltf",
  );
