Join me as I conduct a live tutorial walk through of how to use Facebook's GraphQl/Relay tools to conduct high performance client side cache management in the context of a Ruby on Rails server, React client side stuff(z) and a declarative, non-RESTful, api.

We will be using a live application, source code and tutorials that I've written.
