Problem getting imports to work

[pkyeck]

Bug description

I'm trying to generate zods from our types. We have a lot of files and some of them use types from others. I wrote a script collecting all the filenames and generating a config file (like mentioned here #151) ... looks good so far ... but. I have a problem with the import of another type from a different file:

// a.types.ts
export enum TemplateType {
  Accordion = "accordion",
  AlphabetFilter = "alphabet_filter",
  ArticleHeader = "article_header",
  Audio = "audio",
}

// b.types.ts
import { TemplateType } from "./a.types";

export type TAudioData = {
  a: string;
  b?: string;
};

export type TAudioRequest = {
  _template: TemplateType.Audio;
} & TAudioData;

and my config looks like this:

module.exports = [
  { name: "a", input: "src/a.types.ts", output: "src/a.zod.ts" },
  { name: "b", input: "src/b.types.ts", output: "src/b.zod.ts" },
];

If I now run yarn ts-to-zod --all I get the following error:

$ ts-to-zod --all
Generating "a"
Generating "b"
 ⚠ File "src/a.zod.ts" not found: maybe it hasn't been generated yet?
 ⚠ File "src/b.zod.ts" not found: maybe it hasn't been generated yet?

 🎉 Zod schemas generated!

✨  Done in 1.27s.

If I put all types in one file and run ts-to-zod no error is thrown – so I guess I broke the imports 🤷‍♂️
This should work, right?! Is my config not correct or why am I getting these weird errors?

Ah, forgot to mention, that I uploaded these to a repo as well: https://github.com/pkyeck/test-ts-to-zod

Hello @pkyeck

Indeed, the validation fails because the generated file (which you can check by passing the --skipValidation flag to the command call) looks like this:

// Generated by ts-to-zod
import { z } from "zod";

import { templateTypeSchema } from "./a.zod";

export const tAudioDataSchema = z.object({
  a: z.string(),
  b: z.string().optional(),
});

export const tAudioRequestSchema = z
  .object({
    _template: z.literal(TemplateType.Audio),
  })
  .and(tAudioDataSchema);

The imported import { templateTypeSchema } from "./a.zod"; should be import { TemplateType } from "./a.types";

So it looks like there is an issue with enum imports here...

Ah, thank you. The --skipValidation is really helpful.

"Problem" with enums is, that you can use them as types or values, so we could need both the schema but also the enum itself...

So it looks like there is an issue with enum imports here...
But am I doing something wrong with the export/import enums or is this a bug with the lib?

I think it's a bug (or a missing feature 😅)
