SchemasJS is to runtime validation schemas what DefinitelyTyped is to TypeScript type definitions — a collection of ready-to-use, community-maintained schemas organized by validator library.
Choose your validator (Valibot, Zod, etc.) and get production-ready schemas for common needs — numeric types, binary protocols, typed arrays, and more. Each schema ships with its inferred TypeScript type, so you write once and get full type safety.

@schemasjs/validator |
Validator-agnostic wrapper — write schema-based logic once, swap the underlying validator later |  |
Schemas are tightly coupled to their validator library — a Valibot schema won't work with Zod, and vice versa. @schemasjs/validator provides a thin abstraction layer with a unified API (is(), parse(), safeParse()) so your application code doesn't need to know which validator sits underneath. Define your schemas, wrap them, and swap validators without touching business logic.
import { ValibotValidator, ZodValidator } from '@schemasjs/validator'
// These work identically regardless of the underlying validator
const uint8 = ValibotValidator<Uint8>(Uint8Schema)
uint8.is(255) // true
uint8.parse(42) // 42
