Standard Schema validators

Any validator that implements the Standard Schema specification is supported. For example:

• Zod - TypeScript-first schema validation
• Valibot - Modular schema validation
• ArkType (native) - TypeScript's 1:1 validator

ArkType works both as a validator and as a wrapper for other validators - all via Standard Schema. This means you can freely mix ArkType, Zod, Valibot, and any other Standard Schema validator in the same schema.

npm install arkenv arktype zod

pnpm add arkenv arktype zod

yarn add arkenv arktype zod

bun add arkenv arktype zod

import arkenv from 'arkenv';
import * as z from 'zod';

export const env = arkenv({
  // ArkType DSL
  HOST: "string.host",
  PORT: "number.port",
  NODE_ENV: "'development' | 'production' | 'test'",
  
  // Standard Schema (Zod)
  DATABASE_URL: z.url(),
  API_KEY: z.string().min(32),
});

Need help?

1. Use arktype@>=2.1.28 - or switch to arkenv/standard to drop the ArkType dependency entirely
2. Verify your validator library implements Standard Schema 1.0
