I have in file app.ts:

```
import admin from "./admin";

```

and in file admin.ts:

```
import * as express from "express"
const router = express.router();
var anotherVariable;
...
export default router;
//want to export anotherVariable too

```

How do I also export anotherVariable from admin.ts and how will the corresponding import statements be like in app.ts?
