n4s

n4s is a typed schema validation library (v6.2.1) built as a typed version of 'enforce' for the Vest testing framework ecosystem. It provides compile-time type inference and runtime validation using a chained API. Unlike alternatives like Zod or Yup, n4s is tightly integrated with Vest and follows a similar syntax. Released sporadically, it focuses on small bundle size and TypeScript-first design. Key differentiator: seamless validation integration within Vest test suites.
