The conversion is done by:
const { gltf, metaData } = await ifc2gltf(data);
which extracts gltf together with metaData.
By default, wasm file from npm-package is used. For particular wasm file path, use the syntax prvided with following example:
const { gltf, metaData } = await ifc2gltf(dataString, "./../dist/");
You can import wasm file dynamically from CDN, using the following syntax:
const { gltf, metaData } = await ifc2gltf(dataString, "remote");
