Why I’m Moving from Dev.to to Hashnode

MOHAMMAD SAJJAD ZAKIR — Mon, 04 Aug 2025 09:36:28 +0000

When I first started writing about tech, Dev.to felt like the right place to be. It was welcoming, developer-friendly, and had a vibrant community. For a long time, it gave me everything I needed to begin: a platform to share, to learn, and to be seen.

But over time, as I started thinking more seriously about what I’m building—not just as a developer, but as a creator—I realized I needed something more. Something that felt like home, not just a guest room in someone else’s house. That’s when I started exploring Hashnode.

And I’m moving. Here’s why.

It Finally Feels Like My Own Website Dev.to is a great community blog, but it never truly felt like mine. Every post lived on their domain, and that limited how much control I had over my own content.

Hashnode changed that. It gave me the ability to blog under my own domain, without any setup pain. That simple shift made me feel more like a writer, more like someone taking their craft seriously. Now when someone visits my blog, it feels like they’re stepping into my space—not just a post I left in a larger feed.

The Writing Experience Just Flows I’m someone who enjoys clean, distraction-free writing tools. Hashnode’s editor feels light, modern, and intuitive. It gets out of the way and lets me focus on expressing my ideas without fiddling with formatting.

That clarity is important. Writing is already hard—your tools shouldn’t make it harder.

I Know Who I’m Writing To On Dev.to, I sometimes felt like I was shouting into the void. Posts could take off or disappear quietly, and I had little insight into why.

Hashnode gives me more feedback. I can see what’s working, what’s not, and where readers are coming from. It’s not about chasing numbers—but having that visibility helps me write more intentionally.

Built for Developers, Not Just Writers Hashnode doesn’t just support tech writing—it’s designed for it. From rich code blocks to GitHub integration, everything about it respects the developer experience.

These aren’t flashy features—they’re thoughtful ones. And when you write regularly, they make all the difference.

The Community Hits Different Both platforms have communities, but Hashnode’s feels a bit more focused. Conversations are more thoughtful, feedback is deeper, and connections feel more real.

It reminds me of the early days of the dev blog culture—where people wrote to share, not to go viral. That’s the kind of space I want to grow in.

Not a Goodbye, Just a New Beginning I still appreciate Dev.to. It played a key role in getting me started, and I’ll continue cross-posting some articles there.

But Hashnode is where my writing lives now. It’s where I think clearer, write better, and feel more connected to what I’m building.

Growth Is the Real Reason As developers, we’re always evolving. The tools we use, the platforms we choose, the way we tell our story—it’s all part of that journey.

This isn’t just a platform switch. It’s a step forward in how I want to share, teach, and grow.

If you’re in a similar place, wondering whether it’s worth exploring something new, I’d say: try it. You don’t have to commit forever, but you might find the space that feels like home.

Thanks for reading.

MOHAMMAD SAJJAD ZAKIR — Sun, 06 Jul 2025 13:53:57 +0000

Introduction

Hey everyone! 👋 Today I'm super excited to share with you my latest project - ChatConnect, a full-stack real-time chat application that I built from scratch. This isn't just another chat app - it's a production-ready solution that combines modern web technologies to create an amazing user experience. Let me walk you through the entire journey, from concept to deployment!

🎯 The Vision

I wanted to create something that goes beyond basic messaging. My goal was to build a chat application that feels modern, looks beautiful, and actually works like the apps we use every day. Think WhatsApp Web meets Discord, but with my own unique twist!

🛠️ Tech Stack Deep Dive

Frontend Technologies

React 18 with TypeScript for type safety
Tailwind CSS for stunning, responsive design
Lucide React for beautiful, consistent icons
React Router for seamless navigation
React Hot Toast for elegant notifications

Backend & Services

Share & Join: Friends can join using these codes
Automatic Cleanup: Expired invites are automatically removed
Duplicate Prevention: Smart checks prevent adding yourself or existing friends

Technical Implementation:

// Generate unique invite code
const code = crypto.randomUUID();
await setDoc(doc(db, 'invites', code), {
  userId: currentUser.uid,
  expiresAt: expiresAt,
  used: false
});

💬 Real-Time Chat Engine

The heart of the application! I built a sophisticated chat system with:

Features:

Real-time Message Sync using Firestore listeners
Message Persistence with automatic cloud storage
Timestamp Tracking for message history
Sender Identification with user names and avatars
Auto-scroll to latest messages
Message Formatting with clickable links and video call links

Technical Highlights:

// Real-time message listening
const unsubscribe = onSnapshot(q, (snapshot) => {
  const messagesData: Message[] = [];
  snapshot.forEach((doc) => {
    const data = doc.data();
    messagesData.push({
      id: doc.id,
      text: data.text,
      senderId: data.senderId,
      senderName: data.senderName,
      timestamp: data.timestamp?.toDate() || new Date()
    });
  });
  setMessages(messagesData);
});

🎥 Video Calling Integration

This was the most challenging and exciting part! I integrated Stream Video for professional-grade video calls:

Implementation Process:

Token Generation: Secure server-side token creation
Call Creation: Dynamic call rooms with unique IDs
Link Sharing: Automatic call link generation and sharing
Cross-Platform Support: Works on any device with a browser

Technical Architecture:

// Initialize Stream client
const client = new StreamVideoClient({
  apiKey: STREAM_API_KEY,
  user: {
    id: currentUser.uid,
    name: currentUser.displayName || 'Anonymous',
  },
  token,
});

🔔 Smart Notifications

I implemented a comprehensive notification system:

Browser Notifications for new messages
Permission Handling with user consent
Unread Message Indicators with red dots
Cross-Chat Notifications for multiple conversations

The Evolution of Wearable Tech: What’s Next for 2024? ⌚🧬

MOHAMMAD SAJJAD ZAKIR — Fri, 11 Oct 2024 20:59:38 +0000

Wearable technology has come a long way since the first fitness trackers hit the market. Today, wearables are far more than just step counters—they're transforming health, fitness, and even fashion. As we look toward 2024, what innovations are set to reshape the wearable tech landscape?

The integration of AI-powered health monitoring is a major development. Devices like smartwatches are no longer just tracking your heart rate; they’re using machine learning to predict potential health issues. From irregular heartbeat detection to early signs of diabetes, wearables will continue to evolve as essential tools for personal health diagnostics.

Next, smart fabrics are gaining traction, with clothing embedded with sensors to track vitals like body temperature, stress levels, and hydration. These textiles are being integrated into everything from sportswear to medical garments, creating seamless health monitoring without bulky devices.

Mental health tracking is another rising frontier. Wearables will increasingly focus on cognitive well-being, tracking stress, anxiety, and sleep patterns to offer real-time insights and personalized mental health recommendations. This shift reflects the growing awareness of mental wellness as a critical component of overall health.

Moreover, the concept of wearable ecosystems is emerging, where multiple devices—smart glasses, earbuds, rings—work together to provide a comprehensive picture of a user’s health, fitness, and even productivity. These ecosystems will allow for more personalized and contextual insights, making wearables more indispensable in daily life.

As we head into 2024, wearables will blur the lines between health monitoring, fashion, and everyday utility. The future of wearables is about being more intuitive, responsive, and, most importantly, integrated into how we live, work, and play. What wearable tech are you excited to see in the future? Let’s explore the possibilities!
