💻 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;
  }
>;

We need a repro that doesn't depend on running tsc through pnpm

[baptisteArno]

Repro updated to use latest Typescript and tsc --build. New instructions:

1. pnpm install
2. pnpm tsc --build (or tsc --build if you have tsc binary globally installed and don't want to execute it with pnpm?)
3. See error because schema is of type any

Also figured that when using project references like this, the IDE does not complain and correctly infer the types. But the build still fails:
