Overview of Archetype and Its Unique Features

Archetype is an open-source TypeScript library designed for runtime validation, enabling developers to define types using a syntax that closely resembles native TypeScript. One of its standout features is that definitions can be specified within string literals, allowing the use of TypeScript expressions like unions and parentheses. This makes Archetype both powerful and intuitive for TypeScript developers, who can utilize familiar syntax to validate objects during runtime. Additionally, it incorporates a set-based type system, allowing it to compare schemas and determine if one schema extends another, which positions Archetype uniquely in the TypeScript ecosystem.
