声明模块类型

Question

I have three files:

//some-class.js
class SomeClass {}
module.exports = SomeClass
//helpers.js
const someFunc = () => {}
module.exports = {someFunc}
//index.js
const SomeClass = require("./src/some-class")
const helpers = require("./src/helpers")
module.exports = {SomeClass, helpers}

I need to describe types for them, so I`ve created index.d.ts:

declare module someModule {
 class SomeClass {}
}
export = someModule

But problem with declaring types for helpers , what is the better way to do it?

Answer 1

Fixed it with namespace:

declare module someModule {
  class SomeClass {
    constructor(v: string);
    test: (v: string) => void;
  }

  namespace helpers {
    export function someFunction(v: any): Promise<string>;
  }
}

export = logger;
