Veta — @coderbuzz/veta

Runtime-agnostic schema validation for TypeScript. Faster than Zod. Smaller than Yup. Built-in coercion, sync/async pipelines, context forwarding, and schema metadata — zero dependencies.

Why Veta?

• Object shorthand — { tags: [string()] } not { tags: z.array(z.string()) }
• Built-in coercion — coerce(number()) handles "42" → 42 from form data, query params, env vars
• Async mirror API — objectAsync, arrayAsync, etc. with concurrent execution
• Context forwarding — pass request-scoped data through every validator level
• Schema metadata — METADATA symbol for binary codecs (@coderbuzz/proto)
• Zero deps — <5 KB gzip vs Zod's ~35 KB

Installation

npm install @coderbuzz/veta

Quick Start

import { object, string, number, coerce, optional } from "@coderbuzz/veta";

const User = object({
  id: coerce(number({ min: 1 })),
  name: string({ min: 3 }),
  email: string({ pattern: /@/ }),
  role: optional(string()),
});

const user = User({ id: "42", name: "Alice", email: "alice@example.com" });
// => { id: 42, name: "Alice", email: "alice@example.com" }
