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 🙏

Telefone brasileiro para WhatsApp. Zero dependências de runtime.

import { normalizarTelefoneBR, telefoneBRValido, criarValidadorZapi } from '@chrono-os/whatsapp-br'

normalizarTelefoneBR('(55) 99628-2511') // '5555996282511' — DDD 55 não é confundido com o DDI
telefoneBRValido('123')                  // false

const whatsapp = criarValidadorZapi({
  instance: env.ZAPI_INSTANCE,
  token: env.ZAPI_TOKEN,
  clientToken: env.ZAPI_CLIENT_TOKEN, // faltando qualquer um: modo permissivo, sem chamada
  logger,
})

await whatsapp.temWhatsApp(telefone)  // boolean (permissivo quando a Z-API falha)
await whatsapp.verificar(telefone)    // { temWhatsApp, verificado, motivo? }
whatsapp.saude()                      // { configurado, falhasConsecutivas, minutosDesdeUltimoSucesso, degradado } — para o /health

A regra do DDD 55

d.startsWith('55') ? d : '55' + d está errada: confunde o DDI 55 com o DDD 55 (Santa Maria / Passo Fundo). 55996282511 sai intacto e vira +55 99 6282511. O que desambigua é o tamanho: 10 ou 11 dígitos ganham o 55; 12 ou 13 começando com 55 já têm o país; fora disso, os dígitos voltam crus.

Modo permissivo, monitorado

Se a Z-API falha, a validação deixa o lead passar (não bloqueia gente de verdade). Isso abre um bypass — derrubar a Z-API desliga a validação —, então o validador conta falhas consecutivas, avisa no limiar (10) e loga erro quando a queda passa da janela (5 min). Número malformado continua barrado (false), sem gastar chamada.
