Static adapter does not honor base path for static files

[Ghirigoro]

Describe the bug

1. Create a project with a static adapter.
2. Add this to the config: paths: { base: '/apath'}
3. Build the project
4. Preview the project
5. Note that any files in static folder are resolved at the root and ignore the base path. i.e. localhost:3000/img.png instead of the expected localhost:3000/apath/img.png

I would expect the base path to be honored across the board and not just for js/css files.

Reproduction

NOTE: I'm not sure if this is a bug or static files intentionally must always resolve to the root. If this is expected behavior I'll change this to a feature request, if it is indeed a bug then I will provide a repository highlighting the issue.

Someone kindly pointed out on the discord chat that I can work around this issue by manually prefixing my file paths for things in static with the base path. For example:

<script lang="ts">
  import { base } from '$app/paths';
  //...
</script>
<img src={`${base}/my-static-file.svg`}/>

While a bit tedious it's fine if that's the intended approach, but it does break down in places where you don't have access to $app/paths - e.g. referencing font files in css, or favicons in html.

@Ghirigoro can you set the assets option to be your domain + base directory as an easier workaround?

[benmccann]

Actually, I think this should be fixed by #3346

This does not appear to be fixed. I've just run into this issue on version 1.25.1. The workaround from @Ghirigoro is working.

My svelte.config.js:

const config = {
	preprocess: vitePreprocess(),

	kit: {
		adapter: adapter({
			fallback: 'index.html',
			pages: '../assets/console'
		}),
		paths: { base: '/console' }
	}
};

And my img tag:

Broken on production build but working when runing in dev vite dev:

<img src="/images/image.svg" />

Fixed:

<img src={`${base}/images/image.svg`} />
