Deprecating Schema

GraphQL schemas supports deprecation directive on the fields (which correspond to Kotlin properties and functions), input fields and enum values.

Deprecation of arguments is currently not supported in Kotlin.

Kotlin.Deprecated

Instead of creating a custom annotation, graphql-kotlin-schema-generator just looks for the @kotlin.Deprecated annotation and will use that annotation message for the deprecated reason.

class SimpleQuery {
@Deprecated(message = "this query is deprecated", replaceWith = ReplaceWith("shinyNewQuery"))
fun simpleDeprecatedQuery(): Boolean = false

fun shinyNewQuery(): Boolean = true
}

The above query would produce the following GraphQL schema:

type Query {
simpleDeprecatedQuery: Boolean! @deprecated(reason: "this query is deprecated, replace with shinyNewQuery")

shinyNewQuery: Boolean!
}

GraphQLDeprecated

A side-effect of using @Deprecated is that it marks your own Kotlin code as being deprecated, which may not be what you want. Using @GraphQLDeprecated you can add the @deprecated directive to the GraphQL schema, but not have your Kotlin code show up as deprecated in your editor.

class SimpleQuery {
@GraphQLDeprecated(message = "this query is deprecated", replaceWith = ReplaceWith("shinyNewQuery"))
fun simpleDeprecatedQuery(): Boolean = false

fun shinyNewQuery(): Boolean = true
}
