Using namespace spread over multiple module files in TypeScript

Question

Use re-exporting to create an external module that groups and exposes types from other modules:

// Classes/Animals.ts
export * from '.\Animals\Mammals';
export * from '.\Animals\Reptiles';

Then import the types from the new module as usual:

// app.ts
import * as Animals from '.\Classes\Animals'

let dog: Animals.Dog;
let snake: Animals.Snake;

Or

// app.ts
import { Dog, Snake } from '.\Classes\Animals'

let dog: Dog;
let snake: Snake;
