AH! I encountered the EXACT issue yesterday, couldn't fid the time to investigate :)
If you have a fix ready, feel free to send a PR 🙏

Guessing this is coming from #1118 ? 🤔

Sorry, this is beyond my skills... I think the problem comes from the way the types are imported in the dav code:

import type { Node } from '../files/node'

This seems to make the type part of the dav module, thus ending up replicated in dav.d.ts. Instead, dav.d.ts file should import the type from the main module, like this:

import { Node } from '@nextcloud/files'

Imports are generated only for references to external packages. I don't know how to do that for code from the same package, but that looks to me like a common task for developing library code.

It's not only the Node type getting replicated. Every import from the main module into the dav module would probably have the same problem.

Hey!

Can you try with this instead?

import type { Node } from '@nextcloud/files'
import { resultToNode } from '@nextcloud/files/dav'

function test(node: Node) {
	return node
}

const node = resultToNode(...)
test(node) 

Still does not work for me. I have no experience in testing local libraries. Anything wrong with these steps?

cd $HOME
git clone https://github.com/nextcloud-libraries/nextcloud-files.git
cd nextcloud-files
git checkout fix/imports 
npm run build
cd $HOME/my-project
npm install --no-save $HOME/nextcloud-files/

Creating your test code in my project directory, and passing some compatible argument to resultToNode(), still gives this TS error:

src/lib/test.ts:16:6 - error TS2345: Argument of type 'Node_2' is not assignable to parameter of type 'import("$HOME/nextcloud-files/dist/index").Node'.
  Types have separate declarations of a private property '_data'.

16 test(node)
        ~~~~

As you can see from the message, the module is correctly loaded from the local path.

My real code also gives the same error as before.

@ShGKme @susnux for when you are back 🙈
I don't get it
