`file.exports` always returns empty array

Hey there!

Given the following input code:
```typescript
export const add = async (
   data: {num1: number, num2: number}
) => {
   console.log(`Adding ${num1} + ${num2}`)

   return data.num1 + data.num2
}

export default {
   name: "example-module",
}

```

`file.exports` returns an empty array. 

Am I using this library wrong, or isn't `file.exports` implemented yet?
