Uncaught TypeError: Failed to resolve module specifier "buffer". Relative references must start with either "/", "./", or "../".

Hi guys, first of all, thank you all for your amazing work on OpenLayers :)

Now, here comes the problem 😛

I'm getting the error :

Uncaught TypeError: Failed to resolve module specifier "buffer". Relative references must start with either "/", "./", or "../".

in the browser, when importing

import { WebGLPoints } from 'ol/layer.js';

in my .ts file, and bundling it with Parcel with the following options :

"type": "module",
"targets": {
      "target-name": {
            "outputFormat": "esmodule",
            "isLibrary": true,
            "optimize": false,
            "includeNodeModules": true,
            "source": "file-name.ts",
            "distDir": "."
      },
}

I think it comes from the file ol/worker/webgl.js, because it tries to use Buffer from NodeJS when Blob from the browser is not available.

Do you have any idea on how to solve this problem ?

Thanks :)

I have tried to create a minimal setup to reproduce the problem, using your base setup (but upgrading versions), and Parcel warns me with this :

@parcel/resolver-default: Auto installing polyfill for Node builtin module "buffer"...
