从单个文件导出打字稿类和接口

Question

I want to be able to export some of my classes/interfaces/enums from other files in a single file. This is how I have done it in javascript:

module.exports = {
    Something = require("./src/something").default,
    SomethingElse = require("./src/something-else").default
}

I've noticed that I do not get intellisense from my webstorm (jetbrains) editor, and I'm pretty sure that there is an easier way to implement this in typescript. I've heard and read about modules but I still don't get what they purpose is, most likely they could help me here.

I want to be able to use this style on the library consumer:

import { Something, SomethingElse } from "my-ts-library";
...

Any ideas?

You can flow my example:

Something.ts

export default (a: number, b: number): number => {
  return a + b;
};

SomethingElse.ts

export default (a: number, b: number): number => {
  return a - b;
};

my-ts-library.ts

import add from './src/Something.ts';
import sub from './src/SomethingElse.ts';
export {
  add,
  sub,
};

using your lib

import { add, sub } from "my-ts-library";
...
