Additional context

This is an upstream issue with unimport, here's a related PR, just doesn't cover JSX/TSX files: https://github.com/unjs/unimport/pull/229

I'll try and open a PR soon.

Looks like unimport is looking for index files when importing the directory (with an index file in it)...

https://github.com/unjs/unimport/blob/8a622c9c38d28ee9a80e7c0b8cb82bea05a69766/src/scan-dirs.ts#L94-L97

But it doesn't look for JSX/TSX extensions...

https://github.com/unjs/unimport/blob/8a622c9c38d28ee9a80e7c0b8cb82bea05a69766/src/scan-dirs.ts#L41-L48

So it tries to read the directory as a file, and we get this error

Quick fix:

-export * from './iframe'
+export * from './iframe/index.tsx'

I created an issue on unimport, will probably open a PR at some point once I figure out how to setup a valid test.
