Valibot adapter

@xndrjs/domain-valibot integrates Valibot schemas with @xndrjs/domain.

It provides:

• valibotToValidator(schema) to produce domain validators
• valibotFromKit(kit) to use domain kits as Valibot schema fields
• full re-export of @xndrjs/domain for convenient imports

Install

pnpm add @xndrjs/domain-valibot valibot

Minimal example

import * as v from "valibot";
import { domain, valibotToValidator } from "@xndrjs/domain-valibot";

const Email = domain.primitive("Email", valibotToValidator(v.pipe(v.string(), v.email())));

const email = Email.create("dev@example.com");

valibotToValidator

Wrap any compatible Valibot schema into the domain validator contract:

const User = domain.shape(
  "User",
  valibotToValidator(
    v.object({
      id: v.pipe(v.string(), v.minLength(1)),
      email: valibotFromKit(Email),
    })
  )
);

valibotFromKit

Use valibotFromKit when a parent Valibot schema should materialize an existing primitive or shape kit.

const Address = domain.shape(
  "Address",
  valibotToValidator(
    v.object({
      city: v.pipe(v.string(), v.minLength(1)),
      country: v.pipe(v.string(), v.length(2)),
    })
  )
);

const User = domain.shape(
  "User",
  valibotToValidator(
    v.object({
      id: v.string(),
      address: valibotFromKit(Address),
    })
  )
);

const user = User.create({
  id: "user_1",
  address: { city: "Rome", country: "IT" },
});

When Valibot fits well

Valibot is a good match when you want:

• composable function-first schemas
• small boundary parsers
• explicit parser pipelines
• adapter interoperability without changing the domain model
