caliban

The base type for all Caliban errors.

A GraphQL[-R] represents a GraphQL API whose execution requires a ZIO environment of type R.

It is intended to be created only once, typically when you start your server. The introspection schema will be generated when this class is instantiated.

A GraphQLAspect is wrapping type similar to a polymorphic function, which is capable of transforming a GraphQL into another while possibly enlarging the required environment type. It allows a flexible way to augment an existing GraphQL with new capabilities or features.

A GraphQLInterpreter[-R, +E] represents a GraphQL interpreter whose execution requires a ZIO environment of type R and can fail with an E.

It is a wrapper around a GraphQL API definition that allows adding some middleware around query execution, and possibly transform the environment or the error type.

Represents a GraphQL request, containing a query, an operation name and a map of variables.

Represents the result of a GraphQL query, containing a data object and a list of errors.

A root resolver contains resolvers for the 3 types of operations allowed in GraphQL: queries, mutations and subscriptions.

A resolver is a simple value of the case class describing the API.
