A tool to Convert JSON schemas into TypeScript Deno classes

In plain words

This tool converts JSON schemas into TypeScript utility classes for use in Deno projects. It automatically generates TypeScript interfaces for compressed and uncompressed data versions, includes built-in compression, decompression, and validation features using Ajv, and allows generated classes to be reused across Deno projects. Currently supporting a subset of JSON schema features, it was created as a learning exercise to streamline structured data handling with language models.
