I found a few possible errors, one which is breaking for me

[ADRFranklin]

So I ignored a few of the issues since, this project is still early, and they were only type issues that I could work around, but with version 0.3.0 another issue has cropped up that breaks things for me.

So the major issue that breaks things for me now, is the fact then after updating to 0.3.0 I am presented with

Error [ERR_PACKAGE_PATH_NOT_EXPORTED]: Package subpath './errors' is not defined by "exports" in /workspace/node_modules/@nahkies/typescript-koa-runtime/package.json

and the small but workaround issues that I have found since day one of using this, is also related in a way to the above, but not caused by it.

Cannot find module '@nahkies/typescript-koa-runtime/server' or its corresponding type declarations.ts(2307)
Cannot find module '@nahkies/typescript-koa-runtime/zod' or its corresponding type declarations.ts(2307)

it seems the runtime has no issues with these paths, but typescript does, and adding /src/ after @nahkies/typescript-koa-runtime path fixes the typescript issues, so it's just a simple path rewrite that needs to happen for the typescript types.

One last possible issue that I think you overlooked was you are linking joi definitions for zod.

openapi-code-generator/packages/typescript-koa-runtime/package.json

Line 37 in 6d6183a

"types": "./dist/joi.d.ts"

It's possible one or more of these issues are related to my setup, so do let me know, thanks.

Okay, ignore the first issue, I had updated the runtime, but yarn apparently didn't do it properly, just removed and reinstalled the packages and that fixed the issue.

Raised #119 to address the .d.ts issue, though it should be a red herring as by design the public API to the zod and joi portions of the runtime is expected to be identical.

For the:

Cannot find module '@nahkies/typescript-koa-runtime/server' or its corresponding type declarations.ts(2307)
Cannot find module '@nahkies/typescript-koa-runtime/zod' or its corresponding type declarations.ts(2307)

It would be helpful to see your tsconfig.json and the typescript version - my best guess is it will be caused by the moduleResolution parameter (docs). I'm fairly certain it needs to be:

"moduleResolution": "Node16",

and would recommend using https://github.com/tsconfig/bases/tree/main#node-20-tsconfigjson or equivalent as a base configuration which sets this by default

I've added a types workaround for your package, which fixed the issues in this, but as requested here is my tsconfig.json file. I can't remember what I based this tsconfig off, but it was a year ago.

I'll take a look at the config you posted.
