Augmentations for the global scope can only be directly nested in external modules or ambient module declarations(2669)

I would like to store my NodeJS config in the global scope.

I tried to follow this => Extending TypeScript Global object in node.js and other solution on stackoverflow,

I made a file called global.d.ts where I have the following code

declare global {
    namespace NodeJS {
      interface Global {
          config: MyConfigType
      }
    }
  }

Augmentations for the global scope can only be directly nested in
external modules or ambient module declarations.ts(2669)

but doing this works fine =>

declare module NodeJS  {
    interface Global {
        config: MyConfigType
    }
}

the problem is, I need to import the file MyConfigType to type the config, but the second option do not allow that.

You can indicate that the file is a module like so:

export {};

declare global {
namespace NodeJS {
interface Global {
config: MyConfigType
}
}
}
