Release Notes

Structural changes

GraphQL[R, Q, M, S, E] is simplified into GraphQL[R].
GraphQLInterpreter[R, E] is a wrapper around GraphQL that allows changing the R, the E and running any wrapper around the execution. It's obtained by just calling .interpreter on the GraphQL object. The execute method is available on this object.
It is now possible to combine GraphQL objects with |+|. This allows splitting a large API into smaller chunks and work around Scala limitation of 22 fields.

Example:

val api1 = graphQL(...)
val api2 = graphQL(...)
val api = api1 |+| api2

Query Analyzers

A query analyzer is a piece of code that is executed on a query before its execution. It allows you to analyze the queries and possibly rejecting it, transforming it or running an effect.
This release comes with 2 builtin analyzers for limiting query depth and number of fields:

val api = 
  maxDepth(2)(
    maxFields(5)(
      graphQL(...)
    )
  )

You can use your own by implementing a function with the following signature (with Field being the root query field):

Field => ZIO[R, CalibanError, Field]
