ES6模块：重新导出为对象

Question

I have moduleA which exports some functions:

// moduleA.js
export function f1() {...}
export function f2() {...}

Is there any way to re-export all exports of moduleA in moduleB and make it looks like one object:

// moduleB.js
export * as a from 'moduleA';  // pseudo code, doesn't work

So that I can use it in this way?

// main.js
import {a} from 'moduleB';
a.f1();
a.f2();

Answer 1

The syntax is not supported yet but there is a proposal for it .

You can use it now with Babel.js or simply do:

import * as a from '...';
export {a};

Answer 2

file1.js

export let uselessObject = {
  con1 : function () {
    console.log('from file1.js')
  }
}

file2.js

import { uselessObject } from './file1.js'

uselessObject.con2 = function(){
  console.log('from file2.js ')
}

export { uselessObject } from './file1.js'

Index.js

import { uselessObject } from './file2.js'
uselessObject.con1()
uselessObject.con2()

Output

from file1.js
from file2.js
