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 🙏

Visual debugger for DOM line breaks, wrapping, and layout detection

Readme

Visual Debugger

🚀 Visual Debugger adalah library JavaScript modular untuk mendeteksi baris visual (line-break, wrapping, dan layout) pada elemen HTML di browser. Cocok untuk analisis layout, debugging UI, atau membuat fitur "read more", tooltip per baris, dan lainnya.

✨ Fitur Utama

✅ Deteksi dan ambil data baris yang di-wrap, <br>, atau akibat CSS flow. ✅ Highlight baris tanpa mengubah DOM asli
✅ Mendukung elemen inline, block, dan kombinasi nested
✅ API sederhana & clean

🔧 Instalasi

1️⃣ NPM

npm install visual-debugger

2️⃣ Manual (Browser)

Unduh VisualDebugger.js, lalu:

<script src="VisualDebugger.js"></script>

🚀 Penggunaan

ES Module (Modern)

import visualDebugger, { VisualDebugger } from './VisualDebugger.js';

const v = visualDebugger(document.querySelector('.target'));
v.highlight();
console.log(v.lines);

CommonJS (Node.js)

const { visualDebugger, VisualDebugger } = require('./VisualDebugger.js');

const v = visualDebugger(document.querySelector('.target'));
v.highlight();

Browser Global

<script src="VisualDebugger.js"></script>
<script>
  const v = visualDebugger(document.querySelector('.target'));
  v.highlight();
</script>

✨ API

VisualDebugger(el)

Instansiasi class baru:

const v = new VisualDebugger(el);

visualDebugger(el)

Helper function untuk instansiasi cepat:

const v = visualDebugger(el);

Method/Property | Keterangan ------------- | ------------- highlight() | Tampilkan highlight pada baris visual. clear() | Hapus semua highlight. lines | Akses data semua baris (array).

🌍 Dukungan Lingkungan

✅ ES Module

✅ CommonJS

✅ Browser (<script>)

📊 Struktur Data lines

Setiap baris visual direpresentasikan sebagai objek:

{
    node: Node,          // Node asal
    x: Number,           // Posisi X (viewport)
    y: Number,           // Posisi Y (viewport)
    top: Number,         // Dimensi kotak
    left: Number,        // Dimensi kotak
    right: Number,       // Dimensi kotak
    bottom: Number,      // Dimensi kotak
    height: Number,      // Dimensi kotak
    width: Number,       // Dimensi kotak
    text: String         // Teks pada baris
}

🧪 Contoh Test

HTML:

<div id="testElement" style="width: 300px; height: auto;">
  Baris pertama.<br><br>
  Baris kedua dengan <a href="#">link</a>.
  <div style="height: 50px;">Blok lain</div>
  Baris terakhir.
</div>

JS Test:

import VisualDebugger from 'visual-debugger';

const dbg = new VisualDebugger(document.querySelector('#testElement'));
console.log(dbg.lines);

✅ Hasil: Array dengan data per-baris (termasuk baris kosong & wrapping).

🔥 Catatan Tambahan

Khusus untuk development frontend heavy:

  • Cocok dipakai untuk inspeksi layout, debugging truncation, read more, dan tooltip.
  • Bebas dimodifikasi untuk kebutuhan spesifik.
