Resolver return types do not have to match actual return types?

[tetchel]

Hi,

I built a simple demo backend using this library, and it works. I am overall really impressed by the DX this provides.

However, one quirk I have noticed is that the return type declared by the @Query decorator does not have to match the function's actual return type.

Working example:

Broken example:

There should be an error pointing out the disconnect between the declared Query return type of a [Customers]! and the actual return type of number.

Is this simply a limitation of the library, and it's up to users to make sure the types match? Or am I missing something?

Thanks for any help.

This is the limitation of TypeScript. In ideal world it would just read : Promise<number> type annotation and emit Float! in GraphQL.
