Using Zodios in a Monorepo

[epotter2297]

I'm having some difficulties getting zodios to work in a monorepo correctly, so I set up a simple example here based on the turborepo starter project to demonstrate the problem. When I look at the router, I see that the type is _zodios_core_lib_utils_types.IfEquals<Api, any, Omit<Router, "use"> & ZodiosUse<Context> & ContextRequestHandler<Context>, Omit<Router, any> & ZodiosHandlers<...> & ContextRequestHandler<...>>

I'm not 100% sure if this is a bug, or something configured incorrectly in my tsconfig, so I wanted to check here before making an issue for it.

the setup repository seems wrong :

  "version": "0.0.0",
  "description": "",
  "main": "index.ts",
  "module": "dist/index.mjs",
  "scripts": {
    "dev": "tsm index.ts"
  },

  }
}

tsconfig is not setup in packages

Oh whoops, I had that at one point but I removed it while simplifying things. Just pushed up a change removing the reference (shouldn't be needed anymore).

I'm pretty sure it has something to do with the tsconfig, because if I delete it, it starts working. I'll keep looking and see if I can't narrow down what the problem is in the meantime.

@ecyrbe I think my problem doesn't have anything to do with monorepos at all, so I removed it from the example.

In the updated example, you can see that with the empty tsconfig (which should just load defaults), req is of type any. When you delete the empty tsconfig.json, it starts to work as intended again.

Having an empty tsconfig would surely not work, because zodios needs to have strict mode activated.

But i have setup a mono repo with turbo repo and the issue i see is 'TS4023' error because of unamed exports.

It has to do how types are exported and the tsconfig options on the turborepo base.json file.
you can disable declaration: true and declarationMap: true and set them to false.

i've packaged a fix for the exports (@zodios/express v10.4.1), because i see unamed exports for @zodios/express, but the issue might also be on other packages.
i'll check a full setup.

@epotter2297 so with @zodios/express v10.4.2 and the default turborepo setup, everything works ok.

here the web project package dependendencies:

{
  "name": "web",
  "version": "0.0.0",
  "private": true,
  "scripts": {
    "dev": "next dev",
    "build": "next build",
    "start": "next start",
    "lint": "next lint"
  },

    "@tanstack/react-query": "^4.13.0",
    "@zodios/core": "^10.4.3",
    "@zodios/express": "^10.4.2",

[epotter2297]

Perfect! I think that's everything sorted out, and I also found out that using "moduleResolution": "NodeNext" instead of "moduleResolution": "Node" was breaking some things for me too.
