It's conceivable that we will create some example repos for these, eg: https://github.com/exponentjs/hello-graphql shows you how to set up Exponent with a GraphQL backend, using Apollo Client. We currently have a blank, tabs (with some other features such as push notifications pre-configured) and a game template (https://github.com/exponentjs/game-template).
It would be great for the community to create some of these templates as well, we're still a small team of 8 and building and maintaining a bunch of these could add a lot of overhead.
