Hi everyone, could anyone help me? I have an expired_at field, and I want to send a value true when expired_at is greater than the date now, does anyone know how to do this?

This cannot be done (yet), so you'll have to do it on the client. However, there are a number of Feature Requests for computed fields, custom resolvers, etc.

With a Custom Query?

You're very limited in the kind of data you can return from a Custom Query. You can't return an array yet, for example. And you can't use nested Types. So it's really not suitable for this use-case

@agartha Thanks for your help, I will have to do this on the client side
