Writing NPM packages with ES6 using the Babel 6 CLI
This guide is part of The Complete Guide to ES6 with Babel 6 series. If you’re having trouble upgrading to Babel 6, start with Six Things You Need To Know About Babel 6. Even if you write your NPM package with ES2015, it is important that the code you publish is compatible with everyone else’s JavaScript environments. That means compiling your code to ES5 before publishing it. And of course, the b
