Summary

• A language schema that is VERY HARD to do it correctly
• Defines a strict contract between backend and frontend
• Not a database but a query language bridge service between backend and frontend
• All “POST”, you have to build your own cache layer between resolvers and graphQL endpoint
• Relay is the right way from now, but it’s very hard to use
