A TypeScript library and CLI tool that generates JSON Schema documents from TypeScript type definitions. It parses TypeScript source files via the compiler AST and produces standards-compliant JSON Schema, including JSDoc-derived descriptions.

Use cases

• generate schema from typescript types
• validate api payloads against typescript interfaces
• create schema for config files from ts types
• produce openapi-compatible schemas from typescript source
• cli tool to generate schema from a tsconfig project
• keep schema in sync with typescript code

When to choose

• your types are defined in TypeScript and you need JSON Schema as the source of truth for validation
• you want JSDoc comments carried into schema descriptions
• you need a programmable library plus a CLI in one package

When to avoid

• your types live in other languages like Python or Go
• you need OpenAPI documents rather than plain JSON Schema
• you want runtime type validation itself rather than schema generation
