Ways to organize class and interface files within the same namespace in TypeScript

I'm tackling a Typescript query related to namespaces and organizing files. Within a single namespace, I have multiple interfaces and classes that I'd like to separate into individual .ts files. The goal is to then combine these files so that when I declare the namespace in another code file, I can easily access all the interfaces and classes within it. To illustrate, let's start with the first file, icontact.ts:

export namespace mynamespace {
  export interface IContact {
    firstName: string;
    lastName: string;
  }
}

Moving on to the second file, contact.ts:

import {IContact} from './icontact.ts';
export namespace mynamespace {
  export class Contact implements IContact {
    firstName: string;
    lastName: string;
    constructor(firstName: string, lastName: string){
      this.firstName = firstName;
      this.lastName = lastName:
    } 
  }
}

If anyone could lend a hand with this setup, I would be extremely grateful.

Many thanks in advance.

Typescript namespaces provide a way to organize modules, but they do not automatically generate any code for you.

To effectively use namespaces, it is recommended to create a single file (such as index.ts in a directory) where you can import and re-export all the necessary components.

For example, an index.ts file could look like this:


export { ComponentA } from './component-a';
export { ComponentB } from './component-b';

Now if someone wants to use these components, they can reference them like so:


import * as MyComponents from './some/directory';

let a: MyComponents.ComponentA;
let b: MyComponents.ComponentB;
