arkenv/standard

arkenv/standard is the ArkType-free entry point. Use it when you want Standard Schema validators (Zod, Valibot, etc.) without pulling in ArkType as a dependency.

When to use it

¹ ArkEnv extends ArkType with custom keywords like string.host and number.port

² Only works with Standard JSON Schema validators like Zod 4, Zod Mini and Valibot - see Coercion

✅ Built-in / first-class support

❌ Not supported

In a new project, prefer arkenv. arkenv/standard exists for migrations and ArkType-free setups.

Usage

import arkenv from 'arkenv/standard';
import { z } from 'zod';

const env = arkenv({
  PORT: z.coerce.number().int().min(0).max(65535),
  DATABASE_URL: z.url(),
});

Requirements

A validator that implements Standard Schema (e.g. zod@>=3.24.0, valibot@^1.0.0).
