How can I use declaration file inside npm package using typescript?

Question

I have a package in my node_modules folder which has typings.d.ts and package.json In package.json I set "types": "typings.d.ts"

typings.d.ts

export { T1, T2, T3} from '@somepackage';

interface Window {
    additionalProp: any;
}

export declare var window: Window;

And when I'm using this declaration file in some service:

import { window } from '../typings';


export class SomeService {
    someMethod(): void {
        if (window && window.additionalProp) {
           someLogic();
        }
    }
}

I have no compilation errors But when I build a project, I get next errors:

Module not found: Error: Can't resolve '../typings'

I've read about declare module, triple dash imports, etc. nothing really helped :(

You don't use a relative path with modules in node_modules . You'd import those types by using

import { window } from "the-package-name/typings";

...where the-package-name is the name of the package in node_modules that contains typings.d.ts .
