How do I export and import object from one repository to other? – Javascript

I have 2 github repositories written in typescript
one for initial data , next one project

what is the correct way to export and import it

here is code from initials repository

import { listInitials} from "./src/list";
import { settingsInitials} from "./src/settings";
import { IInitials } from "./src/types";


const initials : IInitials= {
  listInitials,
  settingsInitials
}

export default initials

Their types

export interface IListInitials extends Object {
    [key: string]: any;
 }

export interface ISettingsInitials extends Object {
    [key: string]: any;
}  

export interface IInitials{
  listInitials: IListInitials ,
  settingsInitials: ISettingsInitials 
}

package.json from main repositroy

"dependencies": {
    "initials": "git+https://github.com/username/initials.git",
}

index.ts file where I try to import it

import * as Initials from "initials";
console.log(Initials);

Error in console

./node_modules/initials/index.ts 6:15
Module parse failed: Unexpected token (6:15)
