juusaw/ts-to-io

Leverages TypeScript's compiler API to parse type definitions and generate corresponding io-ts codecs, supporting unions, intersections, tuples, and partial types while optionally following import statements to generate validators across multiple files. Available as both a CLI tool and programmatic API, with configuration options to control output formatting and import resolution. The generated validators are meant for build-time use, enabling type-safe runtime validation without manual codec definitions.
