Create a zod type from a TS enum

Right now if you want to create a type from a TS enum, you have do something like the following:

enum PlantLifecycle {
  Evergreen = 'EVERGREEN',
  Deciduous = 'DECIDUOUS',
  SemiDeciduous = 'SEMI_DECIDUOUS'
};

const lifecycle = z.union([
  z.literal(PlantLifecycle.Deciduous),
  z.literal(PlantLifecycle.Evergreen),
  z.literal(PlantLifecycle.SemiDeciduous),
]);

There should be an easier way of doing this, like:

enum PlantLifecycle {
  Evergreen = 'EVERGREEN',
  Deciduous = 'DECIDUOUS',
  SemiDeciduous = 'SEMI_DECIDUOUS'
};

z.enum(PlantLifecycle);

hey folks, I implemented this in zod@1.11 as z.nativeEnum. documented here. give it a shot!

Just implemented a basic version of this that works for both enums and const objects.

const Fruits = { Apple: 'apple', Banana: 'banana' } as const;
const fruitEnum = z.fromEnum(Fruits);

// "apple" | "banana"
type fruitEnum = z.infer<typeof fruitEnum>;

enum Fruits {
  Apple = 'apple',
  Banana = 'banana',
}
const fruitEnum = z.fromEnum(Fruits);

// Fruits
type fruitEnum = z.infer<typeof fruitEnum>;

Any alternative naming suggestions? @chrbala @johncantrell97 @maneetgoyal @silasdavis
