## What it is
A TypeScript library and CLI tool that compiles TypeScript sources and generates JSON Schema definitions from their types. It handles required properties, extends, annotations, and defaults, and is explicitly in maintenance mode.

## Use cases
- generate json schema from typescript types
- validate api payloads against typescript interfaces
- create json schema for config files from ts types
- generate forms from typescript definitions
- produce json schema docs for a typescript library

## When to choose
- you have a TypeScript codebase and need JSON Schema for validation or forms
- you want a lightweight, simple schema generator with CLI and programmatic API

## When to avoid
- you need advanced or actively developed schema generation features - prefer ts-json-schema-generator
- your sources are not TypeScript

## Facets
- artifact type: library
- maturity: maintenance
- function: parser, serialization, cli, developer-tools
- domain: developer-tools, apis, web-development, files
- platform: cli, cross-platform
- tags: json-schema, typescript, code-generation, schema-generator, validation, nodejs
