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 🙏

Validators for various types of data and occasions.

Español

Validadores para diversos tipos de datos y ocasiones. Todos los validadores son funciones que aceptan 2 parámetros:

  • value : Valor a validar.
  • config : Configuración a usar por el validador (opcional). Es un objeto para permitir configurar el validador.

El validador debe retornar true en caso de ser válido el valor.

Validadores disponibles

  • number:
    • max-value : Verifica si el valor numérico es menor o igual al valor especificado.
    • min-value : Verifica si el valor numérico es mayor o igual al valor especificado.
  • string:
    • email : Verifica si el texto puede ser considerado como un email.
    • max-length: Verifica si el texto tiene una longitud máxima especificada.
    • min-length: Verifica si el texto tiene la longitud mínima requerida.

Ejemplo de uso

const assert    = require('assert');
const maxLength = require('jf-validators/src/string/max-length');
const minLength = require('jf-validators/src/string/min-length');

const value     = 'Lorem ipsum'; // Texto con 11 caracteres.

// Verifica que la longitud mínima sea 0 (valor por defecto).
assert.equal(true, minLength(value));
// Verifica que la longitud mínima sea 255 (valor por defecto).
assert.equal(true, maxLength(value));
// Configuración de los validadores de tal manera que fallen.
const config = {
    // La longitud máxima permitida es menor que la del valor actual.
    maxLength : value.length - 1,
    // La longitud mínima permitida es mayor que la del valor actual.
    minLength : value.length + 1
}
// false: la longitud actual es de 11 pero el máximo permitido es 10
assert.equal(false, maxLength(value, config));
// false: la longitud actual es de 11 pero el mínimo permitido es 12
assert.equal(false, minLength(value, config));
