NestJS Schema First GraphQL Serialization

I've done some research into the subject of response serialization for NestJS/GraphQL. There's some helpful information to be found here, but the documentation seems to be completely focused on a code first approach. My project happens to be taking schema first approach, and from what I've read across a few sources, the option available for a schema-first project would be to implement interceptors for the resolvers, and carry out the serialization there.

Before I run off and start writing these interceptors, my question is this; is there any better options provided by nestjs to implement serialization for a schema first approach?

If it's just transformation of values then an interceptor is a great tool for that. Everything shown for "code-first" should work for "schema-first" in terms of high level ideas of the framework (interceptors, pipes, filters, etc). In fact, once the server is running, there shouldn't be a distinguishable difference between the two approaches, and how they operate. The big thing you'd need to be concerned with is that you won't be easily able to take advantage of class-transformer and class-validator because the original class definitions are created via the gql-codegen, but you can still extend those types and add on the decorators necessary if you choose.
