This sample app follows Architecture, file structure, components, one-way dataflow and best practices suggested by @toddmotto on this repo angular-styleguide
The app is really really simple, it is supposed to be a starting point to building an Angular 1.x app using es2015.
It is also a good companion to reading the Style Guide.

I am working on a more eye friendly version (using angular-ui).
