Overview

Currently experimentalDts does not emit the correct type definitions when moduleResolution is set to either Node16 or NodeNext. The _tsup-dts-rollup.d.ts file is trying to import from the index.d.ts file which causes a circular reference.

Reproduction

1. Clone the branch containing the reproduction by running:

git clone -b experimentalDts-NodeNext https://github.com/aryaemami59/repros

2. Install the dependencies:

yarn install

3. Run the following command:

yarn run build:node-next

4. Inspect the output in the dist directory.

I will submit a PR for the fix.
