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 🙏

Esta paquete contiene metodos acerca de retos de programacion que resolvi en la pagina de codewars.com. Dichos metodos cuentan con una breve documentacion con la herramiento jsDocs.

para utilizarlo simplemente se hace la instalacion normal del paquete:

npm install paquetesnpm

Los metodos principales a utilizar son los siguientes:

Metodo para determinar si una cadena es alfanumerica devuelve true o false.

    /**
 * Metodo que determina si la cadena dada por el usuario es o no alfanumerica.
 * @param {string} string 
 * @returns un valor booleano si la cadena dada por el usuario es alfanumerica
 */
export function alphanumeric(string){
  //your code here
  const hasWhiteSpacesOrUnderScores = /\s/.test(string) || /[_!]/.test(string)
  if(!hasWhiteSpacesOrUnderScores) {
    return /\w/.test(string)
  }
  return false
}

Metodo para generar cadenas con hashtags en base a una cadena recibida, devuelve la cadena formateada.

    /**
 * Metodo que dada una cadena genera dicha cadena pero con formato de hashtag.
 * @param {string} str 
 * @returns la cadena previamente formateada con el hashtag
 */
export function generateHashtag(str) {
  console.log(str)
  if (!str) return false;
  const arrOfWords = splitString(str).map((word) => upperCaseFirstLetter(word));
  arrOfWords.unshift("#");
  const hashtag = arrOfWords.join("");
  console.log(hashtag)
  return hashtag.length > 140 || hashtag == "#" ? false : hashtag;
}

Metodo que encripta una cadena mediante un algoritmo sencillo de encriptacion.

    /**
 * Metodo que codifica una cadena en un algoritmo sencillo
 * @param {string} str 
 * @returns la cadena previamente codificada
 */
export function rot13(str) {
  const rotString = str.split("").map(item => isUpperCase(item) ? determineLetter(item).toUpperCase() : determineLetter(item)).join("")
  return rotString
}
