Installation

Install the core package:

npm install validup --save

Optionally pick one or more integrations:

npm install @validup/standard-schema --save           # Standard Schema (zod 3.24+, valibot, arktype, …)
npm install @validup/zod --save                       # zod-specific (richer issue mapping)
npm install @validup/validator-js validator --save    # validator.js string validators
npm install @validup/vue --save                       # Vue 3 forms

Requirements

Requirement	Version
Node.js	>=22.0.0
Module format	ESM only — "type": "module" (or a bundler that resolves "exports")
TypeScript	5.x recommended

All packages publish ESM-only (dist/index.mjs + dist/index.d.mts). There is no CJS build. If your runtime is CJS, use a bundler that re-emits ESM, or await import('validup').

Peer dependencies

Package	Peer deps
validup	—
@validup/standard-schema	validup ^1.0.0
@validup/zod	validup ^1.0.0, zod ^4.0.0
@validup/validator-js	validup ^1.0.0, validator ^13.0.0
@validup/vue	validup ^1.0.0, vue ^3.3

Verifying the install

import { Container } from 'validup';

console.log(typeof Container); // 'function'

If the import resolves and TypeScript picks up the types from dist/index.d.mts, you're set. Continue to Quick Start.
