Module '".../node_modules/zod/index"' has no default export. import type z from 'zod';

Confirm this is a Node library issue and not an underlying OpenAI API issue

• This is an issue with the Node library

Describe the bug

I am programming an assistant using the openai library but when trying to build my code it gives the following error.

../../node_modules/openai/helpers/zod.d.ts:2:13 - error TS1192: Module '"../node_modules/zod/index"' has no default export.

2 import type z from 'zod';
              ~

  ../../node_modules/zod/index.d.ts:1:1
    1 export * from "./lib";
      ~~~~~~~~~~~~~~~~~~~~~~
    'export *' does not re-export a default.

[3:27:12 PM] Found 1 error. Watching for file changes.

Shouldn't it be better to import only the necessary types from zod instead of all types?

import type { infer as _infer, ZodType } from 'zod';

This way, it would benfit tree-shaking as we are only importing what we need.

To Reproduce

1. Install the openai library
2. Build node in watch mode

Tree-shaking shouldn't matter here as we're using the type import modifier which means that import is never included in the output JS in the first place.

I'm not sure why you're seeing a type error though, can you share your package.json, tsconfig etc?

Of course!

We're also getting this error in our Typescript project.

I haven't had a chance to test out the provided reproduction yet, would you be able to edit the installed package to verify if just importing the symbols needed fixes the issue?

[enricrp-rea]

@RobertCraigie yes, I did it yesterday and it solved the error when importing the needed symbols

import type { infer as _infer, ZodType } from 'zod';

I guess the problem is that zod library does not export a default (node_modules/zod/index.d.ts) and as the error sais, "export * does not re-export a default (export default z is located in node_modules/zod/lib/index.d.ts) so you need to import always the symbols you need. Or you could also import it as

import type * as z from 'zod';

[RobertCraigie]

Great thank you! Will have a fix out later today.

[enricrp-rea]

thank you 👍

[RobertCraigie]

This should be fixed in v4.57.3!
