Self-reference in validators

Hi folks, Is it possible to somehow use self-references in validators, e.g.: 
export const folderValidator = v.object({
  id: v.number(),
  files: v.array(fileValidator),
  subFolders: v.array(folderValidator),
});
export const folderValidator = v.object({
  id: v.number(),
  files: v.array(fileValidator),
  subFolders: v.array(folderValidator),
});
Doing this now results in TypeScript error Variable 'folderValidator' is used before being assigned. Please let me know if I can provide additional context. Thank you!

No, this isn't possible. You can either use IDs like foreign keys or validate this shape manually and use v.any() for the DB validator.
