The issue arises when being used with the typescript plugin.

I am sorry but I am not sure what answer this question is looking for.

No?

Code Snipped

The issue is complex enough for me to create a repo where it can be reproduced in.

https://github.com/CodeMedic42/rollup-dts-issue

There is a README

I will however try to elaborate.

I have a React component and hook library. I want to generate js files from typescript files. Each component and hook are separate chunks. I am managing multiple entry points via the exports option in the package.json. It is also through this I am exporting the types for each component. I want the types generated to be colocated with the generated js files. However when I run the build rollup-plugin-dts creates a whole new folder aside from the one created by the typescript plugin.

Would someone be able to help me understand what is going on here?

@CodeMedic42 you can resolve this issue by changing your input from an array to an object with explicit chunk names

const input = Object.fromEntries(
  Object.values(packageJson.exports).map((chunk) => {
    const source = chunk.import
      .replace("/dist/", "/src/")
      .replace(".mjs", ".ts");
    const entry = source.replace(/\.\/src\/|\.ts/g, "");
    return [entry, source];
  }),
);
