Hey this is awesome! Looks like I'm getting the following error:

base.js:1357 Uncaught Error: Undefined nameToPath for module$Users$dehli$Desktop$re_frame$node_modules$graphql_anywhere$node_modules$apollo_utilities$lib$bundle_umd

Any ideas? Also your core.cljs is missing a delimiter ([react :refer [createElement]]). I would submit a PR but don't think I can for a gist. 😄

Edit: I think the problem line is [apollo-cache-inmemory]... will update this comment with progress.
