Which schema libraries implement the spec?

Standard Schema

Flat layout

Here is an example using Zod or Valibot with the flat layout:

src/env.ts

import  from "./generated/env.gen";
import {  } from "zod";

export const  = ({
	: .().(),
	: .().(),
	: .(["development", "production", "test"]),
});

src/env.ts

import  from "./generated/env.gen";
import * as  from "valibot";

export const  = ({
	: .(.(), .()),
	: .(.(), .()),
	: .(["development", "production", "test"]),
});

Strict layout

You can freely mix Zod or Valibot schemas with the strict layout:

src/env/internal/shared.ts

import {  } from "zod";

/**
 * @internal 🛑 INTERNAL SCHEMA ONLY.
 * Do not import this directly. Import `env` from `./client` or `./server` instead.
 */
export const  = .({
	: .(["development", "production", "test"]).("development"),
});

src/env/internal/shared.ts

import * as  from "valibot";

/**
 * @internal 🛑 INTERNAL SCHEMA ONLY.
 * Do not import this directly. Import `env` from `./client` or `./server` instead.
 */
export const  = .({
	: .(.(["development", "production", "test"]), "development"),
});
