make vite generate relative URLs

Howdy artisans,

how can I make vite generate relative URLs?

I already tried this:

import { defineConfig } from 'vite';
import laravel from 'laravel-vite-plugin';

export default defineConfig({
	plugins: [
	    laravel({
	        input: ['resources/css/app.css'],
	        refresh: true,
	    }),
	],
	base: ''
});

But all I get are still absolute URLs when including the CSS file by using:

@vite('resources/css/app.css')

Any idea what I do wrong here?

Using

ASSET_URL="/"

Had the effect of generating incorrect URLs like:

//build/assets/app-b30c7c50.css

setting it to

ASSET_URL=""

or

ASSET_URL=null

had no effect at all (meaning still absolute URL was generated).
