Arktype is a TypeScript runtime validation library and schema orchestrator. It synchronizes TypeScript types with runtime data validation, allowing users to define type-safe schemas that ensure unknown data adheres to specific structures during application execution. The project distinguishes itself by using set-theory type analysis to determine intersections and subtype compatibility, alongside JIT-compiled validation functions for optimized performance. It supports advanced type modeling through branded type constraints, recursive alias resolution, and the ability to generate runtime valida

magic-regexp is a type-safe regular expression builder and TypeScript compiler. It allows for the construction of JavaScript regular expressions using a readable syntax that automatically generates precise types for captured groups, ensuring predictable data extraction. The project functions as a build-time transformer that converts custom pattern syntax into standard regular expression objects. This static compilation removes runtime overhead by shifting the transformation logic to the build process. The tool covers named capture group generation and a readable construction API that replace
