Best directory structure for React + Meteor

I currently built my Meteor app using React as the view layer. Everything works great but when I use mupx to deploy to my server and go to the deployed app it throws “There is no route for the path: /”.

I have came to assume that it is due to the directory structure I’m using (routes.js is in my client dir) and was wondering if anyone could point me in the right direction of the correct directory structure to use?

Thank you
