Everyone needs a to do app, especially when we are making a new project in a new language or framework. I think I have 100 of these in some form or other by now. This To Do app is for elite hackers only, since you need a GitHub login.

React, Node, Webpack, UUID, Foundation, Firebase, Karma, Heroku, HTML, CSS
TDD, Save items, Reactive components, Responsive design, 3rd party (GitHub) authentication
