A sample application integrating Ionic 2 with GraphQL using the Apollo Client for Angular2
I have created a graphQL server using express and I used json-server as my persistence layer to work through API calls and such. If you are interested in the server, see the server here on Glitch.
Server: https://aks-graphql-sample1.glitch.me
