Why does this "import WebGL"-statement not work in my Vite-Project?

The statement:

import { WebGL } from 'three/addons/capabilities/WebGL.js';

About my project setup:

  • I created the root folder using "npm create vite@latest"
  • ran "npm install" and then "npm install --save three"
  • ran "npm run dev" which is defined in package.json as "vite"
  • body of index.html has this line:
<script type="module" src="/main.js"></script>

  • Main.js includes the line from the top as well as code for a basic three.js scene, which I copied from Three.js's official documentation

  • When I run the server I get a blank white page.

The browser console shows this error:

Uncaught SyntaxError: The requested module '/node_modules/.vite/deps/three_addons_capabilities_WebGL__js.js?v=fc132b03' does not provide an export named 'WebGL' (at main.js:40:10)

I'm confused because the statement is suggested in the official three.js docs. I know I could use an absolute path instead of the alias, but I'd like to understand why it's not working as-is. Just trying to learn.

Thanks in advance


  • I think it is exported as default. So you have to import it like this: import WebGL from 'three/addons/capabilities/WebGL.js';

    But I still have the issue that my IDE (Visual Code on Ubuntu) says: Cannot find module 'three/addons/capabilities/WebGL.js' or its corresponding type declarations. Probably while working with typescript, I would need another install for the types, but I am not sure.
