somehow when move typed function out of the router files, frontend infer type to be any ?

this is inferred corrected since they are in the same file.

getX: t.procedure.query(() => {
 return getX()
}) 

function getX(): X{
  ...
}

getX: t.procedure.query(() => {
 return getX()
}) 

function getX(): X{
  ...
}

getX: t.procedure.query(() => {
 return getX()
}) 

export function getX(): X{ << moving this out of the file breaks the typing.
  ...
}

getX: t.procedure.query(() => {
 return getX()
}) 

export function getX(): X{ << moving this out of the file breaks the typing.
  ...
}

What exactly do you refer as typing is broken? I think I got the same issue and my types result to any I made a repo that reproduces my issue, not sure its the same https://stackoverflow.com/questions/74185198/typescript-losing-zod-and-trpc-types-across-monorepo-projects-types-result-in

I have a simar issue with a turbo repository, where 'second hand' types are infered as any, e.g. I have a package with the TRPC API, which might return types from an external package. I use the TRPC package types in our app, but all types that are infered from external packages are any, all types that I give directly are fine. One solution I have is to use references in tsconfig like this:

{
  "references": [
    {
      "path": "../../packages/api-service"
    }
  ]
}

{
  "references": [
    {
      "path": "../../packages/api-service"
    }
  ]
}

BUT I believe this might have performance impact + it's annoying to have to think about adding this to every package that consumes the API service types
