discover graphql mutations, queries, subscriptions?

is it possible to discover graphql mutations, queries, subscriptions?

Yes, it should be possible. You will just have to refer to the NestJS code to determine what metadata gets attached when those decorators are used and then you can use the Discovery package to look them up

I try to do this

import { NestFactory } from '@nestjs/core';
import { Module } from '@nestjs/common';
import { DiscoveryModule, DiscoveryService } from '@golevelup/nestjs-discovery';
import { GraphQLSchemaBuilderModule } from '@nestjs/graphql';

@Module({
  imports: [
    DiscoveryModule,
    GraphQLSchemaBuilderModule
  ]
})

class CustomModule {}

const main = async () => {
  const app = await NestFactory.create(CustomModule);
  await app.init();

  const discoveryService = app.get(DiscoveryService);
  const resolvers = await discoveryService.providersWithMetaAtKey('graphql:resolver');

  console.log(resolvers)
};
main();

which returns an empty array, I am not sure that the code I have is 100% correct.
