Directive on MUTATION

[daniil-kzn]

What happened?

1. define directive @checkMutation on OBJECT | MUTATION in schema.graphqls
2. add the new directive to mutation type Mutation @checkMutation {...}
3. define the directive in the application gql config

gqlConfig.Directives.CheckMutation = func(ctx context.Context, obj interface{}, next graphql.Resolver) (res interface{}, err error) {
    return nil, nil
}

What did you expect?

Application runtime goes to CheckMutation func

Minimal graphql.schema and models to reproduce

directive @checkMutation on OBJECT | MUTATION

input NewTodo {
  text: String!
  userId: String!
}

type Todo {
  id: ID!
  text: String!
  done: Boolean!
  user: User!
}

type Mutation @checkMutation {
    createTodo(input: NewTodo!): Todo!
}
