uuidv5 的打字稿声明，同时导出枚举和默认函数

Question

我正在尝试为 uuidv5 创建一个 Typescript 声明，这是我对第 3 方模块的第一个声明，他们使用的是我不理解的构造。脱衣服的模块看起来像：

function uuidToString(uuid) {
}

function uuidFromString(uuid) {
}

function createUUIDv5(namespace, name, binary) {
}

createUUIDv5.uuidToString = uuidToString;
createUUIDv5.uuidFromString = uuidFromString;

module.exports = createUUIDv5;

我尝试创建这样的声明：

declare module uuidv5 {
    type uuid = string | Buffer
    enum space { dns, url, oid, x500, null, default }
    type ns = uuid | space

    export interface createUUIDv5 {
        (namespace: ns, name: uuid): uuid;
        (namespace: ns, name: uuid, binary: boolean): uuid;

        uuidToString(uuid: Buffer): string;
        uuidFromString(uuid: string): Buffer;
        createUUIDv5: uuidv5.createUUIDv5;
        space: uuidv5.space;
    }
}

declare const exp: uuidv5.createUUIDv5;
export = exp;

这几乎得到了我想要的，除了我无法访问空间枚举使用

var uuidNs = uuidv5(uuidv5.spaces.null, "My Space", true);
                    ------------------
var uuid = uuidv5(uuidNs, "My Space", true);

我浏览了文档，但找不到在其中添加该枚举的方法，同时仍然能够将其用于顶部的类型定义...

declare module uuidv5 {
    type uuid = string | Buffer
    enum space { dns, url, oid, x500, null, default }
    type ns = uuid | space

    export interface createUUIDv5 {
        (namespace: ns, name: uuid): uuid;
        (namespace: ns, name: uuid, binary: boolean): uuid;

        uuidToString(uuid: Buffer): string;
        uuidFromString(uuid: string): Buffer;
        createUUIDv5: uuidv5.createUUIDv5;
        spaces: typeof uuidv5.space; // notice this line
    }
}

declare const exp: uuidv5.createUUIDv5;
export = exp;

我不建议使用declare module uuidv5 格式，因为它已被弃用。 ES6 模块兼容环境模块更好。

declare module 'uuidv5' {
    type uuid = string | Buffer
    enum space { dns, url, oid, x500, null, default }
    type ns = uuid | space

    interface createUUIDv5 {
        (namespace: ns, name: uuid): uuid;
        (namespace: ns, name: uuid, binary: boolean): uuid;

        uuidToString(uuid: Buffer): string;
        uuidFromString(uuid: string): Buffer;
        createUUIDv5: createUUIDv5;
        spaces: typeof space;
    }
    var exp: createUUIDv5
    export = exp
}

使用中：

import * as uuidv5 from 'uuidv5'

var uuidNs = uuidv5(uuidv5.spaces.null, "My Space", true);
