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 🙏

cm-tunnel

v1.0.0

Published

Exponha seu servidor HTTP local para a internet através do Cloudflare ou LocalTunnel de forma simples

Readme

cm-tunnel

Exponha seu servidor HTTP local para a internet através de uma API extremamente simples. Suporta Cloudflare e LocalTunnel.

Instalação

npm install cm-tunnel

Requisitos

  • Node.js >= 18
  • Para usar o provedor do Cloudflare, o executável cloudflared deve estar instalado no sistema e disponível no PATH. Caso não esteja, a biblioteca emitirá um erro amigável.

Uso

API Principal

import tunnel from 'cm-tunnel';

try {
  const t = await tunnel({
    provider: 'cloudflare', // ou 'localtunnel'
    port: 3000
  });

  console.log('Túnel público:', t.url);

  t.on('ready', (url) => console.log('Pronto:', url));
  t.on('close', () => console.log('Túnel fechado'));
  t.on('error', (err) => console.error('Erro:', err));

} catch(err) {
  console.error(err.message);
}

API Simplificada

import tunnel from 'cm-tunnel';

// Usando cloudflare
const t1 = await tunnel.cloudflare({ port: 3000 });

// Usando localtunnel
const t2 = await tunnel.localtunnel({ port: 3000 });

Objeto de Retorno

A função retorna uma Promise que resolve em um objeto TunnelInstance contendo:

  • provider (string): O nome do provedor utilizado.
  • url (string): A URL pública gerada pelo túnel.
  • port (number): A porta local.
  • stop() (function): Método para encerrar o túnel corretamente.
  • process (any): Acesso ao processo interno (ChildProcess para cloudflare ou objeto do localtunnel).

O objeto retornado também é um EventEmitter, emitindo os eventos ready, close e error.

Adicionando novos provedores

A arquitetura de cm-tunnel é modular. Para adicionar um novo provedor:

  1. Crie um arquivo em src/providers/[nome-do-provedor].ts.
  2. Exporte como default uma classe que estenda a classe Provider.
  3. Implemente o método abstrato start(): Promise<TunnelResult>.
  4. O núcleo carregará automaticamente o novo provedor quando chamado com provider: '[nome-do-provedor]'.
