ES6 Modules: transitively exporting symbols (i.e., from imported files)

Question

Suppose I\'m creating an ES6 library with multiple files, but have a root file that contains all of the top-level definitions. How could I achieve something like this exampl

You have to re-export:

lib/main.js
import { Sub } from './foo/sub';
export { Sub };

You can re-export directly like this:

export { Sub } from './foo/sub';

You can rename when exporting:

export { Sub as MySub } from './foo/sub';

Or re-export everything:

export * from './foo/sub';
