Export as default multiple imported modules

How do I export as default multiple imported modules?

I could do something like the code below, but if I were to import multiple files the boilerplate could grow quickly. Is there a shorthand way to achieve this? 

import Foo from './Foo'
import Bar from './Bar'
//...

export default {
    Foo,
    Bar
    //...
}

Note that in my code above, I'm not exporting multiple values. I'm importing multiple values, accumulating them, and exporting them as a single object. I intend to refer to the reexported values by Baz.Foo or Baz.Bar, assuming the code above is Baz.js.

Instead of accumulating boilerplate from importing lots of files to simply re-export them, you can do this:

// In library.js
export { default as Foo } from "./Foo.js";
export { default as Bar } from "./Bar.js";

// In new_file.js
import { Foo, Bar } from "../lib/library.js"
var phooey = new Foo();

This selects whatever you are exporting as default and gives it an alias.

import * as name from "module-name";

This will be a great fit for your application. And when you want to access the object, you can use

name.object = ...;

And let me know, if it is right.

In es6 there are two types of exports named and default exports.

Since you want to export default assign all the modules to an object like below

Const modules = {Foo,  Bar }
export default modules;

Then in other files use like below

Import modules from 'path/yourfiles'
modules.Foo.xxx
modules.Bar.xxx

export default is not meant to be used with multiple exports: https://developer.mozilla.org/en-US/docs/web/javascript/reference/statements/export#Using_the_default_export

If we want to export a single value or to have a fallback value for your module, you could use a default export

You should use named exports like this:

export {
    Foo,
    Bar
    //...
}
