A way to conditionally hide a field

[gherciu]

Describe the issue
I did read the docs but could not find any feature to conditionally hide a field.

I have a simple use case, Each user in my DB has a email, now in some cases I want to return it in Graphql response and in some not, what is the best way to implement it?

Should that be done just in the resolver, or is there a type-graphql Decorator to hide a field conditionally?
Or maybe I should use a FieldResolver and it will override the original return with what I want?

Use @if directive on your frontend to query or not the field, based on role/other things.
On server side, put @Authorized() decorator on that field or use field resolver to add more logic to return value of field or throw error.

TypeGraphQL has middleware.

Although I think it is generally recommended to do things that involve authorization inside a business logic layer. See also this link particularly about business logic layers.
