如何使用默认函数导出为commonjs模块创建类型？

Question

这里是我正在做打字的代码：

https://github.com/jden/objectid/blob/1.1.0/index.js

我到目前为止已经试过 -

尝试＃1：

declare module "objectid" { 
    interface ObjectId { 
    (): string 
    isValid(objectId: string): boolean 
    } 
    export default ObjectId 
} 

... 
import makeObjectId from 'objectid' // Error TS2304: Cannot find name 'makeObjectId' 

尝试＃2：

declare module "objectid" { 
    interface ObjectId { 
    (): string 
    isValid(objectId: string): boolean 
    } 
    export = ObjectId 
} 

... 
import makeObjectId = require('objectid') 
const id = makeObjectId() // Error TS2304: Cannot find name 'makeObjectId' 

尝试＃3：

declare module "objectid" { 
    export default function makeObjectId(): string 
    export function isValid(objectId: string): boolean 
} 

... 
import makeObjectId = require('objectid') 
const id = makeObjectId() // TypeError: objectid_1.default is not a function

编辑：工作的人的解决方案，认为这在未来：

declare module "objectid" { 
    interface ObjectId { 
    (): string 
    isValid(objectId: string): boolean 
    } 
    declare var objectId: ObjectId 
    export = objectId 
} 

... 
import * as makeObjectId from 'objectid' 
const id = makeObjectId()

您可以尝试在你的d.ts文件中声明它是这样的：

declare module "objectid" 
{ 
    interface ObjectId 
    { 
     (): string 
     isValid(objectId: string): boolean 
    } 

    var foo: ObjectId; 

    export default foo; 
}
