Ask HN: What are some exemplary React apps to study?

Take a look at [1] React Redux App by Richard Park. It has very well-formed app structure.

Not a full fledged app, but React Boilerplate (http://reactboilerplate.com/) is pretty nice in terms of the structure and pattern it follows.

Check out this video which explains it pretty nicely: https://vimeo.com/168648012
