I've been working to build some front-end components with CSS and some JS code. I've built the JS library using TypeScript and some vanilla JS. The structure of my code is:

• /src/alert.ts
• /src/modal.ts
• /src/dropdown.ts
• etc...

Each script file is laid out roughly like this:

export class Modal {
  constructor(element: Element|string, options: ModalOptions) {
    doSometing();
  }
}

I want to be able to compile my library and bring it into my Angular application like:

import { Modal } from 'mylibrary';

let modalInst = new Modal(Element, {
  someProperty: true
});

For the life of me, I can't figure out what I'm missing in order to get Angular to see my classes as modules. Can someone point me in the right direction?
