ES6`从导入导出*？

Question

Is there a syntax using ES6 or ES7 or babel which will allow me to easily bundle together many groups of sub files?

Eg, given:

./action_creators/index.js
./action_creators/foo_actions.js
./action_creators/bar_actions.js

Have index.js import foo and bar actions, then re-export them, so I can

import {FooAction, BarAction} from './action_creators/index.js'

I don't want to have to remember / change references if I were to change which file I've organized the objects themselves into.

Answer 1

Yes, ES6 supports directly exporting imported modules :

export { name1, name2, …, nameN } from …;

export {FooAction, BarAction} from './action_creators/index.js'

You can also re-export all exports of the imported module using the * syntax:

export * from …;

export * from './action_creators/index.js';

Answer 2

Default export as Default :

export {default} from './something';

Default export as Named :

export {default as foo} from './something';

Named export as Default :

export {foo as default} from './something';

Named export as Named :

export {foo} from './something';

Named export as Renamed :

export {foo as bar} from './something';
