Would it work for your use case to do the reverse, turning validators into types? Here's an example how to do that:

export const taskGroup = v.union(
  v.literal("Personal"),
  v.literal("Work"),
  v.literal("Family"),
  v.literal("Church")
)

export type TaskGroup = Infer<typeof taskGroup>

export const taskGroup = v.union(
  v.literal("Personal"),
  v.literal("Work"),
  v.literal("Family"),
  v.literal("Church")
)

export type TaskGroup = Infer<typeof taskGroup>

There may be a way to go the direction you asked. I just haven't played with it yet (or searched for a solution) to find out how.

There's not unfortunately, types in TypeScript don't exist at runtime. There are a variety of ways to try to do this with codegen/bundler extensions but nothing supported now.
