Re-export default in ES 6 modules

This is a bit of repetition from the previous answers, but to clarify the difference in two options:

1. Default export

(This appears to be what OP wants)

// index.ts
export { default } from './App'

Then, in a different file:

import App from './index'

2. Named export

export { default as App } from './App'

Then, in another file:

import { App } from './index'

Bonus: named → default export

If ./App uses a named export, but you want to re-export it as a default export, you can do that too:

export { App as default } from './App'

Then, in another file:

import App from './index'

These will work with react as vsync's answer states.


If you use proposal-export-default-from Babel plugin (which is a part of stage-1 preset), you'll be able to re-export default using the following code:

export default from "./App.js"

For more information see the ECMAScript proposal.


Another way (without this plugin) is:

export { default as App } from "./App.js"

The above is a very common practice when separate files, each with its own export, have all something in common, for example, utils, so if, for example, one would want to import 3 utility functions, instead of having to write multiple imports:

import util_a from 'utils/util_a' 
import util_b from 'utils/util_b' 
import util_c from 'utils/util_c' 

One could import any of the utilities in a single-line:

import { util_a, util_b , util_c } from 'utils' 

By creating an index.js file in the /utils folder and import all the defaults of all the utilities there and re-export, so the index file will serve as the "gateway" for all imports related to that folder.
