🔍 Introducing responsive-debugger: Instantly Visualize Breakpoints While Developing

Great! Since you’ve published a package called responsive-debugger on npmjs.com, writing a professional, SEO-optimized, developer-focused blog post can drive traffic, build trust, and help monetize your work over time.

🚀 Overview

One of the most overlooked — yet critical — parts of frontend development is responsive design debugging. While tools like Chrome DevTools are powerful, they can be cumbersome for quick layout visualization.

That's why I built responsive-debugger — a lightweight, plug-and-play utility to instantly visualize screen size breakpoints right in the browser, during development.

✅ Key Features

  • 📐 Displays screen size + breakpoint in real-time
  • 🧠 No DevTools toggling
  • 🪶 Tiny footprint — no external dependencies
  • 🎨 Customizable themes and position
  • ⚡ Framework-agnostic (React, Vue, Svelte, plain HTML, etc.)
  • 🛠️ Perfect companion for Tailwind, Bootstrap, or any responsive CSS framework

📦 Installation

You can install responsive-debugger globally or as a dev dependency:

npm install responsive-debugger --save-dev
Enter fullscreen mode Exit fullscreen mode

Or using Yarn:

yarn add responsive-debugger --dev
Enter fullscreen mode Exit fullscreen mode

🔧 Usage

Just import and initialize it in your app (preferably only in dev):

import { injectDebugger } from 'responsive-debugger';

injectDebugger({
  position: 'top-right', // top-left | top-right | bottom-left | bottom-right
  theme: 'dark', // or 'light'
  breakpoints: {
    sm: 640,
    md: 768,
    lg: 1024,
    xl: 1280,
    '2xl': 1536,
  },
});
Enter fullscreen mode Exit fullscreen mode

The breakpoint viewer will appear in the corner of your screen showing:

📱 sm | 640px
💻 md | 768px
🖥️ lg | 1024px
Enter fullscreen mode Exit fullscreen mode

💡 Ideal For:

  • Tailwind CSS devs working on responsive layouts
  • Freelancers & agencies doing quick layout audits
  • Frontend teams improving handoff with designers
  • Developers who hate resizing the browser 100 times a day 😅

🧱 Tech Stack

Built using:

  • TypeScript
  • Vanilla DOM manipulation (no frameworks)
  • Zero dependencies — ultra lightweight

🧑‍💻 Why I Built This

As a frontend developer, I was constantly resizing my browser, opening DevTools, checking screen widths — it interrupted my flow. I wanted something always visible but non-intrusive.

So I built responsive-debugger to stay in the zone while building fluid UIs.

📈 Future Plans

  • 🎛️ UI configurator panel
  • 🧩 Chrome Extension version
  • 🔌 Framework plugins (Next.js, Vue, etc.)
  • 💬 Community suggestions!
