SyntaxError: Cannot use import statement outside a module

[ayel01]

Hey everyone,

I have some Problems when trying to import web-ifc-three in my nodeJs Project.
I'm trying to load an ifcModel in my REST Service.
It's just a simple example, but everytime I try to start my backend it throws the following error:

import * as WebIFC from 'web-ifc';
^^^^^^

Node.js v18.15.0

My example-code:

import express from "express";
import IFCLoader from "web-ifc-three";

const app = express();

app.get("/process-ifc", async (req, res) => {
const ifcLoader = new IFCLoader.IFCLoader();
ifcLoader.ifcManager
ifcLoader.load('../rst_basic_sample_project.ifc', (ifcModel) => {
console.log('Model loaded');
});
});

app.listen(3000, () => {
console.log("Server listening at http://localhost:3000");
});

package.json:

{
"name": "ifc-convert",
"version": "0.0.1",
"description": "",
"main": "index.js",
"type": "module",
"scripts": {
"test": "echo "Error: no test specified" && exit 1"

Would be good to see the whole project (a github link?), but you might try to edit package.json file and add "type": "module"
..." main": "app.js", "type": "module", "scripts": { ...
