Alternative to superstruct Describe

See original GitHub issue

In Superstruct the Describe utility returns a type representing a struct for a given valid value type. This allows you to ensure you’re writing your struct definitions properly.

type User = {
  id: number
  name: string
}

const User: Describe<User> = object({
  id: string(), // This mistake will fail to pass type checking!
  name: string(),
})

Is there a way to do something like this in zod?

This is the recommended way to write a schema that implements a particular static type, try it instead: https://github.com/colinhacks/zod/issues/372#issuecomment-826380330

@Djaler Figured it out!

TypeScript Playground

import { z } from "zod";

type User = {
  id: number
  name: string
}

const User: z.ZodSchema<User> = z.object({
  id: z.string(),
  name: z.string(),
})

It’s ZodSchema! h/t 🎩 to https://github.com/colinhacks/zod/issues/372#issuecomment-810905204
