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/express-validator --save  # express-validator chains
npm install @validup/routup --save             # routup HTTP requests
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/zod	zod ^3.25.0 || ^4.0.0
@validup/express-validator	express-validator ^7.3.1
@validup/routup	validup, routup, @routup/basic
@validup/vue	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.
