Type error: Exported variable 'X' has or is using name 'PrdStore' from external module

Bug Description

There was no problem with the code below when jotai 2.8.3 was used.

import { atom, createStore } from 'jotai';

export const xAtom = atom<Array<{ id: string; }>>([]);
export const xStore = createStore();

However, after upgrading to jotai 2.9.3, I received the following error message when I did "Next build".

Type error: Exported variable 'xStore' has or is using name 'PrdStore' from external module

When I checked, it seems to be caused because Store type is not "export".

/* export */ type Store = PrdStore | (PrdStore & DevStoreRev4);

What do you think about adding "export"?

Thanks for reporting. I wasn't aware such a difference.

Hmm, not exporting Store type is intentional, but I see you have the issue with --declaration. Are you developing a library?

I'm not sure if we can go back to v2.8.x type if we do #2687.

Meanwhile, does this workaround work for you?

Thank you for your answer.

It's not even a library development, but the option 'declaration' was turned on in the project. I changed it to false and solved it. 😅

Thank you very much. 🙏

Good to hear.

the option 'declaration' was turned on in the project.

That's interesting.
