import statements in .d.ts file along with declare module does not work

What works =>

I have a index.d.ts file in my app root where I have global things declared for example global modules.

So my index.d.ts looks like following:

declare module 'moment';

and I can import moment in any .ts file without any error.

Where problem arises =>

Now problem arises when I import something in my index.d.ts file to make more declarations. Lets say my as follows:

import { MyService } from './path/to/file';   //line#1

declare module 'moment';

export interface SomeInterface {
 name: string;
 salary: number;
 myService: MyService
}

Now any imports in my .ts file that were importing moment are erroneous and throw Cannot find module 'moment'.ts(2307)

As soon as I comment line#1, the moment imports start working again.

What am I doing wrong here?

Is the MyService class exported in the MyService.ts or whereever it is defined? – Piyush Saxena Jul 24 '19 at 17:25
yes it is an exported member of `'./path/to/file'` – pranavjindal999 Jul 24 '19 at 17:31
This is a problem with mixing ambient module declarations with import statements. You can find more discussion and a potential solution with TS 2.9 [here](https://stackoverflow.com/a/51114250/5416902) – Piyush Saxena Jul 24 '19 at 17:45

thanks man. This is exactly what I was facing and seems like this is how typescript is by design and I'm not doing anything wrong here. – pranavjindal999 Jul 24 '19 at 17:51
Yeah no problem! – Piyush Saxena Jul 24 '19 at 18:01
