Ensure data integrity with a TypeScript-first validation library that offers static type inference and a lightweight, dependency-free footprint.

This library provides a robust way to define schemas that validate data ranging from simple strings to complex, nested objects. By leveraging static type inference, it ensures that your application logic remains type-safe without the need for manual interface definitions. It is designed to be developer-friendly, offering an immutable API where every method returns a new instance, ensuring predictable behavior throughout your codebase.

Key advantages include:

  • Zero dependencies: Keeps your bundle size minimal at just 2kb.
  • Universal compatibility: Runs seamlessly in Node.js and all modern browsers.
  • TypeScript integration: Works perfectly with strict mode to catch errors early.
  • Extensive ecosystem: Integrates with numerous tools for form validation, API development, and data parsing.

Whether you are building a small utility or a large-scale application, this tool helps you eliminate runtime errors by validating untrusted data at the boundaries of your system. With built-in support for JSON Schema conversion and a concise interface, it remains the industry standard for type-safe validation in the JavaScript ecosystem.
