💻 Code

Here is a basic reproduction: https://github.com/baptisteArno/zod-d-ts-issue

1. pnpm install
2. pnpm turbo build --filter=package-three...
3. See error because schema is of type any

🙁 Actual behavior

package-two generates with imports from zod which package is not installed in package-two.

This means that the type that we get when importing things from package-two are of inferred type any

🙂 Expected behavior

I would expect the d.ts file to instead imports from installed packages only.

In that very specific case, I would expect it to generate:

export declare const schema: typeof import("package-one").schema

instead of

export declare const schema: import("zod").ZodObject<
  {
    id: import("zod").ZodString;
    name: import("zod").ZodString;
  },
  "strip",
  import("zod").ZodTypeAny,
  {
    id: string;
    name: string;
  },
  {
    id: string;
    name: string;
  }
>;

github.com/baptisteArno/zod-d-ts-issue で再現することから始め、pnpm install と pnpm turbo build --filter=package-three... を実行し、package-two の生成された宣言を調べます。推論された宣言型に対してコンパイラーがどのようにインポートを選択するかを追跡します。宣言が利用できない zod パッケージを必要としなくなり、期待される package-one への参照を保持すれば完了です。
