GraphQL - a type system for your API
summary
GraphQL is a query language with an introspectable type system that returns exactly the fields requested, uses field arguments and aliases, and so avoids common REST problems like over-/under-fetching. Facebook runs it in production since 2012 and open sources the spec in July 2015; more than 15 language implementations appear within two years. The Scala implementation Sangria wires schema types to case classes, supports HTTP/JSON (Akka HTTP, Play, Finch), works with MongoDB/Elasticsearch, exposes auto-completion via GraphiQL playground, and powers GitHub v4 and Twitter endpoints.
