Problem

When using treeshake: true option, the invalid default export is generated in .cjs files, probably because of rollup usage. When building with rollup's treeshake - @arethetypeswrong/cli gives the following error (see https://github.com/arethetypeswrong/arethetypeswrong.github.io/blob/main/docs/problems/FalseExportDefault.md for error explanation):

However, if we set treeshake: false in tsup.config.ts and rebuild, the error is gone:

To reproduce

  1. git clone https://github.com/AlexShukel/tsup-cts-default-export
  2. pnpm i
  3. pnpm build
  4. pnpm lint

The final distributable directory is dist, so we copy package.json there in pnpm build command. Then, with pnpm lint we call attw to check the package inside dist directory.
