[TypeScript Resolvers] Resolvers returned data type cannot be introspected

Describe the bug Cannot introspect resolvers returned data

To Reproduce Steps to reproduce the behavior:

Clone repository: git clone -b graphql-ts https://github.com/swcarlosrj/SpaceX-API.git Install deps & start server: yarn && yarn start Generate types: yarn generate Introspect src/schema/capsule/resolvers.ts resolvers returned data

Expected behavior This would be the desired behaviour, it’s not even real because I’ve hardcoded QueryResolvers.CapsulesResolver from CapsulesResolver<...> = (Resolver<R, Parent, Context, CapsulesArgs> to CapsulesResolver<...> = Promise<Capsule[]>

I believe that it’s a TypeScript thing but it’d be incredible if we could have that feature using QueryResolvers.Resolvers as here, does it’s even possible?

Environment: OS: macOS Mojave 10.14.2 (18C54) Codegen: 0.15.2 Node: 10.10.0

Additional context It looks like that when you check the returned data type, it’s well formed (in this case Capsule[]) but I cannot see in VSCode the fields of my type/interface as here

Sure, you can close it!

@swcarlosrj this is how TypeScript works.

When you do this:

type Foo = string;

const query = {
  foo(): Foo /* <-- */ {
  	return 'Foo';
  }
}

TypeScript treats that as a shape of a returned value, not as function’s signature.

To have typed arguments and others, you would have to define that signature, otherwise it’s any. That’s why I don’t understand why not to put the TypeResolvers.Resolvers signature next to the object.
