How to export Class and Type

src/
  - foo.ts
  - index.ts

foo.ts

type Bar = {

}
export class Foo {
  bar: Bar
}

index.ts

import { Foo } from './foo'

export class Index {
  person: Foo
}

output

export declare type Bar = {};
declare class Foo {
	bar: Bar;
}
export declare class Index {
	person: Foo;
}

export {};

There are two issues:

1. Foo is not exported.
2. Bar is exported.

why? I am very confused.

I find exporting .d.ts files is the hardest part of typescript.

I really don’t know how to export the type I want.
