AtscriptUniversal Type & Metadata Language

Define types once, generate code for any programming language*

Single Source of Truth

Define types, validation, database schemas, and UI metadata in one place - no more scattered definitions across your codebase

Attach any metadata to your types - from validation rules to database indexes to UI labels - all accessible at runtime

'string.email', 'number.positive', 'mongo.objectId' - types that carry meaning and automatic validation

From one .as file get TypeScript types, runtime validators, database schemas with indexes, and JSON Schema

All annotations are preserved and accessible at runtime for dynamic UI generation, validation, and more

Add custom annotations, create semantic types, write plugins - make Atscript work for your domain

* Language Support

Currently, TypeScript/JavaScript code generation is supported. We welcome contributors to write plugins for other languages!
