## What it is
A Java tool that generates TypeScript definition files (.d.ts) from Java JSON classes using reflection, available as Maven and Gradle plugins. It can also generate TypeScript REST service clients from JAX-RS annotated services.

## Use cases
- generate TypeScript interfaces from Java DTOs
- keep frontend types in sync with Java backend
- generate TypeScript client for JAX-RS REST services
- create .d.ts files during Maven build
- generate TypeScript declarations from Jackson-annotated classes

## When to choose
- you have a JVM backend with JSON APIs and a TypeScript frontend
- you want build-time type generation integrated into Maven or Gradle
- you need REST client stubs generated from Java service definitions

## When to avoid
- your backend is not on the JVM
- you need generation from source code rather than compiled classes
- you use a non-Jackson JSON mapping without supported customization

## Facets
- artifact type: library
- maturity: active
- function: serialization, build-tool, developer-tools
- domain: web-development, developer-tools, apis
- platform: jvm, cli
- tags: typescript-definitions, code-generation, maven-plugin, gradle-plugin, jackson, jax-rs, rest-client-generation
