如何通过index.d.ts和模块定义将类转换为类型?

我有一个typescript+javascript模块,它被编译成一个包,可以由另一个项目导入。我想最好用一些代码来解释,然后再解释我的问题。

需要用作类型的类:

我的-类.ts

export default class MyClass{
    ...
}

import MyClass from './my-class';

export {
  MyClass,
};

索引d.ts

declare module '@package/my-project'{
    export interface MyClass{
        //Am I supposed to declares types here?
    }        
}

import {MyClass} from '@package/my-project';

private myClassInstance: any; //I want this to be :MyClass instead of "any"

beforeCreate(){
    this.myClassInstance = new MyClass();
}

我一直在看下面的链接,但是,真的不知道如何实现这一点。 https://www.typescriptlang.org/docs/handbook/declaration-files/templates/module-d-ts.html

给一些背景,这里是我的tsconfig.json文件文件:

{
  "extends": "./extradetails.json",
  "compilerOptions": {
    "allowJs": true,
    "declaration": false,
    "experimentalDecorators": true,
    "allowSyntheticDefaultImports": true,
    "strictNullChecks": false
  }
}
