Declaration types are missing when re-export default multiple times

[sedx]

Hi! First of all thanks for plugin that can bundle d.ts too! It's killer feature, realy!

But I faced some issue, traditionally details below

---

• Version: 1.3.2
• Rollup Version: 2.23.1
• Operating System and version (if applicable): macOS
• Node Version (if applicable): v12.13.1
• Does it work with tsc (if applicable): N/A

Reproduction

I have package that contains some sub modules (each submodule is separate entry point). Entry point has named exports View and Model (like this)

I placed Views and Models to sub folders and re-export default up-to submodule entry point.

When I build package I get broken type definition. View exported with type typeof default, but default is not defined 😔

Looks like reason is chain of export { default } from './someSourceFile'.

When I used named export all is fine. (here is result for named exports)

Repo with bug reproduction https://github.com/sedx/rollup-ts-bug
I added result of build to repo.

Expected Behavior

declare const _default: {
    foo: string;
    baz: number;
};
declare const Model: typeof _default;
declare const View: typeof MainView(): JSX.Element;
export { Model, View };
//# sourceMappingURL=A.d.ts.map

Actual Behavior

declare const _default: {
    foo: string;
    baz: number;
};
declare const Model: typeof _default;
// ⚠️ default here is not defined
declare const View: typeof default;
export { Model, View };
//# sourceMappingURL=A.d.ts.map

Hey there.
It took me a few years apparently, but this bug has been fixed now and will be part of v2.0.6 when it releases soon.

hi @wessberg! Is it related to a weird behaviour I saw recently #176? By using re-exports, the resulting d.ts file doesn't resolve the inner types correctly.
Is there a way for me to install the v2.0.6? I tried npm i rollup-plugin-ts@next but didn't resolve a version

Update: Just cloned and locally installed. Seems to work fine.

[wessberg]

It is, yes. Your issue is covered by the fix too. It will be released shortly

[diego-toro]

That's Awesome! Thanks @wessberg
