合并模块声明文件中命名空间的接口 [英] Merge interface from namespace in module declaration file

问题描述

我有一个javascript库，该库在此处具有类型定义文件: https://github.com/tyranid-org/tyranid/blob/master/tyranid.d.ts ，该文件通过我的package.json文件中的typings属性公开.

I have a javascript library which has a type definition file here: https://github.com/tyranid-org/tyranid/blob/master/tyranid.d.ts which is exposed via the typings property in my package.json file.

定义文件的基本版本:

export default Tyr;

declare namespace Tyr {
  interface Document {
    $save(): Promise<Document>;
  }
}

我想在一个完全独立的打字稿库中扩展Document接口: https://github .com/CrossLead/tyranid-gracl 通过将$newMethod()方法添加到文档界面来导入tyranid及其类型.能做到吗?

I would like to extend the Document interface in a completely separate typescript library: https://github.com/CrossLead/tyranid-gracl which imports tyranid along with its typings, by adding a $newMethod() method to the document interface. Can this be done?

我在第二个仓库中的一个单独的声明文件中尝试了以下操作，但是它不起作用:

I've tried the following in a separate declaration file in the second repo, but it doesn't work:

import Tyr from 'tyranid';

declare namespace Tyr {

  interface Document {
    $newMethod(): number;
  }

}

如有必要，我可以修改两个声明-很有可能我没有正确编写tyranid的原始类型定义文件.谢谢！

I can modify both declarations if necessary -- its very possible I am not writing the original type definition file for tyranid correctly. Thanks!

推荐答案

以下内容最终可以正常工作...

The following ended up working...

在node_modules/tyranid/tyranid.d.ts中:

export = Tyr // must do "import * as Tyr from 'tyranid'" instead of default

declare namespace Tyr {
  export interface Document {
    // original definition...
  }
}

在mylib/tyranid-extensions.d.ts ...

declare module "tyranid" {
  interface Document {
    addedMethod(): boolean; 
  }
}
