Uncaught SyntaxError: The requested module './js/OrbitControls.js' does not provide an export named 'OrbitControls'

My code is:

		document.body.appendChild( renderer.domElement );

		const scene = new THREE.Scene();

What am i missing?

Are you referring here to the actual ES6 module? You can easily verify this by checking if respective import/export statements are presents in the file’s source code.

Seems no import/export statements are present in OrbitControls.js

Well, that’s the root cause of the issue. You can’t load a non-module file with an ES6 import statement. The following code section should work though:

import * as THREE from "https://threejs.org/build/three.module.js";
import { OrbitControls } from "https://threejs.org/examples/jsm/controls/OrbitControls.js";
import { OBJLoader2 } from "https://threejs.org/examples/jsm/loaders/OBJLoader2.js";
