打字稿定义文件创建

Question

我正在尝试为js库编写一个打字稿定义文件。 该库导出以下项目：

const Joi = require('joi');
module.exports = {
  Joi
};

Joi是一个受欢迎的图书馆，已经定义了类型。 （https://www.npmjs.com/package/@types/joi）

如何在我的定义文件中正确导出预先存在的Joi类型，而无需在定义文件中重新定义命名空间？
这样做的正确方法是什么？

我使用了工具dts-gen（https://github.com/Microsoft/dts-gen）来获得一个想法。它为Joi创建了一个名称空间，如下所示：

export namespace Joi {

    const isImmutable: boolean;

    const isJoi: boolean;

        };

    }

    namespace validate {
        const prototype: {
        };

    }

}

但这对我来说似乎不对。当实际定义已经存在时，我不了解Joi命名空间的必要性。
