TypeScript type access

[antt0n]

Hello,
I'm currently working on a TypeScript project, but I have a problem: I can't export the types.
This causes a problem during compilation: I can't specify a type to which I don't have access.
My goal is simply to store an instance of a port in a class variable.
Here is an example :

import jzz from 'jzz'

class Midi {
  private _port = jzz().openMidiOut();
  private _midiOut: typeof _port; // <= This is the only solution I could find to get around the problem

  ...

  public get out() { // <= And now it's here that I have an error because of the type.
    return this._midiOut;
  }

I can indeed specify the any type to allow me to override this error, but it bothers me for the sake of clarity.
Thanks in advance for your help!

Thanks for the notice!
I have not updated index.d.ts for quite a while due to the lack of time.
I would really appreciate if anybody could take care of the TypeScript side of the project...
