recursive type

I'm trying to declare a dynamic tree structure for layouts (similar to HTML). Is it possible to have a recursive type? I'm trying this

let element_eurofutur = v.union(v.literal("Row"), v.literal("Col"), v.literal("Hoja"),   v.literal("Fijo"), v.literal("Poste") ); 

let node_eurofutur = v.object({   
   element: element_eurofutur,
   children: v.array(node_eurofutur) 
});

let element_eurofutur = v.union(v.literal("Row"), v.literal("Col"), v.literal("Hoja"),   v.literal("Fijo"), v.literal("Poste") ); 

let node_eurofutur = v.object({   
   element: element_eurofutur,
   children: v.array(node_eurofutur) 
});

but getting error

Block-scoped variable 'node_eurofutur' used before its declaration.

I don't think Convex validators support this currently.

ok i'm thinking as a plan B i can use a string as an emmet notation and hydrate it on the client side or not sure if Convex validators support JSON any as a type

You store pretty much any JSON in Convex directly with v.any(). You can even pretend the type is checked with v.any() as Validator<MyType> But the validation will be up to you at your callsites.

Using branded types in validators

If you have a more specific type than what you can express with Convex validators, you can still document that at the type level in Convex by casting ...

sounds good, that might work
