Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

xsd-generated-sunat

Generador Enterprise-Grade de interfaces TypeScript desde archivos XSD (UBL/SUNAT).

Esta herramienta CLI transforma archivos de esquema XML (XSD) en archivos TypeScript (.ts) con tipado estricto, resolviendo automáticamente colisiones de nombres, referencias circulares y dependencias entre namespaces. Ideal para proyectos de Facturación Electrónica que requieren máxima seguridad de tipos.

Características Principales

  • Mapeo de xsd:choice: Convierte bloques de decisión en Union Types de TypeScript para garantizar campos mutuamente excluyentes.
  • Soporte de Enumeraciones: Los códigos de la SUNAT se generan como uniones de strings (autocompletado).
  • Soporte Nativo de Namespaces: Entiende los prefijos de UBL/SUNAT (cac, cbc, ext, etc.) y gestiona los imports automáticamente.
  • CLI Rápido: Procesa cientos de XSDs en segundos manteniendo la jerarquía de carpetas.
  • XJC para TypeScript: Diseñado para ofrecer la misma robustez que el compilador XJC de Java pero con la flexibilidad de TS.

Instalación

Puedes instalarlo globalmente o usarlo directamente con npx:

npm install -g xsd-generated-sunat

Uso del CLI

El comando principal es xsd-ts. Necesitas especificar la carpeta de origen de los XSD y la carpeta de destino:

# Sintaxis
xsd-ts <directorio_origen_xsd> <directorio_destino_ts>

# Ejemplo práctico para SUNAT UBL 2.1
xsd-ts ./esquemas/2.1 ./src/types/sunat

Ejemplo de Código Generado

Los archivos generados incluyen las importaciones necesarias y resuelven conflictos de nombres:

import { AmountType as CCT_AmountType } from './CCTS_CCT_SchemaModule-2.1';

export type AmountType = {
  value: string;
  currencyID: string;
};
