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 🙏

Crear un nuevo paquete de npm desde cero.

Pasos para crear el proyecto

  1. Inicializar CLI en el directorio del proyecto y ejecutar el comando para inicializar npm
npm init
  1. Seguir las instrucciones de CLI: package name (nombre único), version, description, entry point (archivo js de entrada), test command, git repository, keywords, author, license.
  2. Podemos observar que se crea el archivo package.json con la información que proporcionamos.
  3. Como definimos un entry point con el nombre index.js, hay que crear dicho archivo en main ya que aquí ejecutaremos nuestro package.
  4. Crear una carpeta llamada modules en donde vivirá nuestro módulo (lógica de nuestro package).
  5. Dentro de la carpeta modules, crear el archivo parImpar.js para desarrollar la lógica del package. Aquí programamos la función que nos permite determinar si un número es par o es impar (código funcional de mi package).
  6. Exportamos la función creada utilizando el comando:
export default determinarParImpar;
  1. Importar mi función en index.js para poder utilizarla.
import function from route.js
  1. Modificar package.json para permitir la ejecución de módulos de EcmaScript (ES modules) agregando "type": "module" debajo de la clave-valor de "main": "index.js"

Ejecutar el archivo index.js con el comando

node index.js

Pasos para publicar un package en npm

  1. Registrarse en el sitio web de npm npm
  2. Ejecutar el comando de inicio de sesión de npm
npm login
  1. Publicar nuestro package con visibilidad publica utilizando CLI
npm publish --access=public
