i have this simple js sample which i test via visual studio code with live preview server build in: i don't use node.js in this sample all js files under js dir :
C:\Dev\my\javascript\ThreeJS\tests\js>ls -1
GLTFLoader.js
OrbitControls.js
main.js
three.js
three.min.js
three.module.js
HTML:
but i keep getting this general error :
Uncaught TypeError: Failed to resolve module specifier "three". Relative references must start with either "/", "./", or "../".

The following is my code when using cdn without webpack/node.js.
#index.html
<head>
<script type="importmap">
{
"imports": {
"three": "https://unpkg.com/[email protected]/build/three.module.js",
"OrbitControls": "https://unpkg.com/[email protected]/examples/jsm/controls/OrbitControls.js"
}
}
</script>
</head>
<body>
<script type="module" src="js/test.js"></script>
</body>
#test.js
import * as THREE from 'three';
import { OrbitControls } from 'OrbitControls';
scene = new THREE.Scene();
renderer = new THREE.WebGLRenderer();
controls = new OrbitControls(camera, renderer.domElement);

This is because unlike other web resources, the JS modules specification for HTML reserved the space of these non-relative references (called "bare specifiers") exactly to allow custom package imports via import maps.

Also since 26th of January this year three.js released r137 update and since r137 using ES6 modules like GLTFLoader in the browser requires an import map.
<script type="importmap">
{
"imports": {
"three": "../master/three.js-master/build/three.module.js"
}
}
The three.js import statement in your scripts.js looks like so then:
import * as THREE from 'three'
