Lacinia Integration

[domkm]

Lacinia seems to be the most popular Clojure GraphQL server library and, as such, we would like to support common use cases.

Particularly, we would like to be able to automatically instrument resolvers. The exact nature of the instrumentation is an open question.

• What is the interface for attaching specs to schemas?
• How are fspec :fn specs defined?
  • Automatic, based on a naming convention?
  • Argument passed to the function that attaches specs?
• Should resolvers receive conformed or raw data?
• Should resolvers receive invalid data or should that automatically return an error?
  • If the latter, how should the error be formatted?
• Should resolvers that return invalid data (whether by :ret or :fn) throw immediately or cause errors to be attached to the response?
  • If the latter, how should the error be formatted?
• Since most resolvers are anonymous, they cannot participate in clojure.spec's registry. How should we instrument and unstrument anonymous functions?
• Should it be possible to instrument or unstrument individual resolvers?
• Should it be possible to partially instrument or unstrument (use any combination of :args, :ret, and :fn)?
• Should it be possible to partially instrument or unstrument individual resolvers?
