Release es6 and es5 sources with npm

Question

I am developing two node packages registered with npm and using es6 syntax. Each package has only one es6 module exporting one class.

• the package Ahas no dependencies
• package Bdepends onA

Class A

export default class A {...}

Class B

import A from 'A'

export default class B {...}

Each package has the following structure modules/ index.js (es6 source) index.js (commonjs source)

• The source code is in es6/index.js
• It translates to es5 / commonjs using Babel

Question

I want to give users of my packages A and B the choice to use es6 (by importing class B, which itself will import A es6 class, not es5 A) or es5 sources (requiring the es5 B function, which itself requires the es5 A function): What the best way to achieve it?
