Typecheck

An extensible library for runtime type validation.

Provides type safety with static type inference. It offers a modular and tree-shakable structure, allowing you to import only the components you need. The API and codebase are clean, readable, and declarative, making it easy to work with. Additionally, it includes useful utilities for parsing and modifying data. The library comes with a variety of common types as schemas, along with their modifiers. It also provides comprehensive code documentation with examples and variants. Designed based on real use cases, it aims to enhance the developer experience. The library is completely free and licensed under the MIT license.
