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 🙏

cuitonline

v1.2.10

Published

Consultar CUIT, CUIL, DNI o nombre y obtener datos basicos de personas.

Readme

cuitonline

Cliente Node.js para buscar personas en cuitonline.com por DNI, CUIT, CUIL o nombre y leer los datos visibles en resultados y detalle.

Instalacion

npm install cuitonline

Uso basico

const { search, searchByName, getByCuit, getByDni } = require('cuitonline');

async function run() {
  // Buscar por nombre, DNI, CUIT o CUIL
  const hits = await searchByName('Juan Perez');
  console.log(hits);

  // Traer datos completos por CUIT
  const detail = await getByCuit('20-11111111-2');
  console.log(detail);

  // Alias que busca por DNI y devuelve el primer resultado con detalle
  const byDni = await getByDni('20111111');
  console.log(byDni);
}

run().catch(console.error);

Que devuelve

  • search(query) / searchByName(name) -> array de coincidencias { name, cuit, personType, detailUrl, constanciaUrl }
  • getByCuit(cuit) -> resultado que coincide (o el primero) con los campos de search mas los obtenidos en el detalle:
    • name, cuit, personType, gender, nationality, locality, employer, afipErrors (array), detailUrl
  • getByDni(dni) -> usa search(dni) y descarga el detalle del primer resultado.
  • getDetail(url) -> parsea una URL absoluta o relativa de detalle.

Todos los metodos aceptan options con http o client para pasar tu propia instancia de Axios (proxy, timeouts, etc.).

Uso en frontend (via tu backend)

El scraping no puede correrse directo en el navegador por CORS y restricciones del sitio. Crea un endpoint en tu backend y consumilo desde la UI.

Ejemplo Express minimo:

const express = require('express');
const { search } = require('cuitonline');
const app = express();

app.use((req, res, next) => {
  res.set('Access-Control-Allow-Origin', '*');
  res.set('Access-Control-Allow-Headers', 'Content-Type');
  if (req.method === 'OPTIONS') return res.sendStatus(204);
  next();
});

app.get('/api/search', async (req, res) => {
  const q = (req.query.q || '').trim();
  if (!q) return res.status(400).json({ error: 'q is required' });
  res.json({ results: await search(q) });
});

app.listen(3000, () => console.log('proxy listo en http://localhost:3000'));

Luego en el frontend llama http://tu-backend/api/search?q=20111111112 y procesa el JSON.

  • Respeta los terminos de uso y privacidad del sitio origen.
