ES6 `export * from import`?

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';

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';
