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 🙏

easyjs-utils

Libreria leggera di helper JavaScript per la manipolazione del DOM, gestione eventi e classi CSS — senza dipendenze.


🚀 Introduzione

easyjs-utils è una micro-libreria JavaScript (≈2KB minificata) che semplifica le operazioni più comuni sul DOM:

  • Selezione rapida di elementi
  • Gestione di eventi con funzioni shorthand (onClick, onSubmit, onReady, ecc.)
  • Aggiunta, rimozione e toggle di classi CSS
  • Manipolazione HTML e lettura stili
  • Gestione semplificata di form e validazioni

Perfetta per progetti in Vanilla JS o come base utility per piccoli script frontend, senza jQuery.


📦 Installazione e inclusione

🔹 via npm

npm install easyjs-utils

Nel tuo progetto:

import easy from "easyjs-utils";

easy.onReady(() => {
  easy.onClick('#btn', () => easy.toggleClass('#box', 'active'));
});

🔹 via CDN

jsDelivr

<script src="https://cdn.jsdelivr.net/npm/[email protected]/dist/easy.min.js"></script>

unpkg

<script src="https://unpkg.com/[email protected]/dist/easy.min.js"></script>

Una volta inclusa, la libreria è disponibile globalmente come easy.


🧰 Esempi di utilizzo

Selettore e manipolazione del DOM

<div id="box">Ciao!</div>

<script>
  easy.setHtml('#box', '<b>Nuovo contenuto!</b>');
  console.log(easy.sel('#box').innerText); // "Nuovo contenuto!"
</script>

Gestione eventi

<button id="btn">Cliccami</button>

<script>
  easy.onClick('#btn', (el, e) => {
    easy.toggleClass(el, 'active');
  });

  // Esegui codice al caricamento del DOM
  easy.onReady(() => console.log('DOM pronto!'));
</script>

Gestione classi CSS

<div id="panel"></div>

<script>
  easy.addClass('#panel', 'visible');
  if (easy.hasClass('#panel', 'visible')) {
    easy.removeClass('#panel', 'visible');
  }
</script>

Lettura stili CSS

<div id="box" style="margin-left: 20px; width: 200px;"></div>

<script>
  console.log(easy.cssMarginLeftPx('#box')); // 20
  console.log(easy.cssWidthPx('#box'));      // 200
</script>

Gestione form con validazione

<form id="contactForm" novalidate>
  <input type="email" name="email" required>
  <button type="submit">Invia</button>
</form>

<script>
  easy.onValidSubmit('#contactForm', (form, data) => {
    console.log('Form valido:', data);
  });
