class-transformer usage

[kevin-lot]

How can I use https://github.com/typestack/class-transformer to have group serialization?

In my controller, I want to excludeAll and perform serialization only on the properties I want to serialize.
If I do this, no properties are serialized at all, which seems normal since "items" and "meta" do not have the @expose annotation.

How can I do this?

Best regards.
