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 🙏

Memoizer

Motivo

Memoizer es un modulo simple de codigo para memoizar funciones. El motivo principal de este proyecto fue publicar un paquete en npm y setear una configuracion basica de github actions para simular un entorno de desarrollo agil y continuo

Descripcion

Memoizer es un modulo que recibe un callback, del cual en base a sus argumentos memoizara el resultado para no ejecutar el callback una segunda vez.

Por ende los callbacks que se pasen al Memoizer, deben ser funciones puras, sin side effects y que en base a una misma entrada proporcione una misma salida.

Puedes memoizar valores primitivos de la siguiente forma:

import { memoizer } from '@juancho-dev/memoizer'

const sum = (a, b) => a + b
const memoizedSUm = memoizer(sum)

// Executes callback
memoizedSum(5, 5)

// Returns value from cache - does not executes callback 
memoizedSum(5, 5)

Puedes memoizar un callback que recibe objetos como parametros de la siguiente forma:

import { memoizer } from '@juancho-dev/memoizer'

const getNameAndAge = (person) => `${p.name} ${p.age}` 
const memoizedNameAndAge = memoizer(sum)

// Executes callback
memoizedNameAndAge({name: "John", age: 20})

// Returns value from cache - does not executes callback 
memoizedNameAndAge({name: "John", age: 20})
