react-atom-trigger v2: A Scroll Trigger Recipe

Some react-waypoint instinct, a bit of IntersectionObserver magic, a lot of geometry and just enough scheduler spice to keep it sane.I did not want to write just another "how to use my library" article. Not because usage is not important. It is important. But the docs already exist, the examples exist, Storybook exists and I think nobody needs one more article where I just say "install package, import component, pass onEnter".That would be useful maybe, but also a bit boring. And if there is one

Stop memorizing JS — think in execution context

Forget remembering JavaScript syntax; it's a crutch.What if I told you that the key to truly understanding JavaScript isn't memorizing endless functions and methods, but grasping how the code actually runs? This article is about shifting your focus from rote learning to thinking about JavaScript's execution context.Every time your JavaScript code runs, the engine creates an "execution context." Think of it as a mini-environment where your code gets evaluated. There are two main types: the Global

SVG to PNG: Complete Guide for Developers [2026]

When you actually need PNG instead of SVGSVG is the best format for most web content. A vector icon at 2 kilobytes renders pixel-perfect at any zoom level, theme-able with CSS, manipulable with JavaScript, and indexable by search engines if you add title and desc. For buttons, logos, illustrations, and data visualizations, SVG beats PNG on every axis.But there are five places where SVG does not work and you need PNG. First: app icons. iOS and Google Play require fixed-size PNGs — 1024 by 1024 ma

GIF to MP4: Stop Using Animated GIFs in 2026

The uncomfortable truth about GIFsThe Graphics Interchange Format was finalized by CompuServe in 1987. Its animation extension came in 1989. At the time a 256-color palette was luxurious, inter-frame compression was a research topic, and video on the web meant postal mailing a VHS tape. Every design choice in GIF89a makes sense in its historical context. Zero of them make sense in 2026.And yet animated GIF remains absolutely everywhere: support articles, product demos, tutorials, reaction images

Facing issue with dev tool in react native 0.85

Hi everyone,I recently created a new project using React Native CLI (version 0.85). After setting up @react-navigation/drawer, I started facing an issue with the developer tools.When I press "j" in Metro to open the dev tools, it does launch, but the screen appears completely blank (white screen).I’ve been stuck on this issue for the past 3–4 days and haven’t found a proper solution yet.If anyone has faced this problem before or knows how to fix it, please let me know.You can also reach me at: [

Microtasks: Why Promises Run First

This is the third article in a series on how JavaScript actually runs. You can read the full series here or on my website.In the last article, we established that:JavaScript execution cannot be interrupted.Once a macrotask starts, nothing cuts in. Only after it completes does the runtime select the next macrotask from the queue. But consider this:setTimeout(() => console.log("timeout"), 0);Promise.resolve().then(() => console.log("promise"));console.log("sync done");The output is always:sy

I shipped a 147,000-word interactive book as a free SPA — here's the stack

TL;DR — I just shipped The Wanting Mind, a 147,000-word interactive book that reads like Wikipedia + a podcast + a graph. It's free, no signup, all four languages (EN/JA/ZH/TH). The whole thing is a React 19 SPA backed by Supabase, Capacitor for the mobile apps, and a chunk of AI (ElevenLabs for narration, fal.ai for chapter art, Gemini for video, Claude for translation). This post is what worked, what broke, and the stack at the bottom for fellow indie devs. The pitch (60 seconds)It's a lo

How I Accidentally Spent $800/Month on LLM Tokens I Didn't Need (And How to Fix It)

I spent six weeks shipping the wrong thing.I built PromptFuel because I was hemorrhaging money on API calls. Not because I was building at scale—I wasn't. I was building dumb. I'd write a prompt in isolation, test it once, ship it, then wonder why my OpenAI bill jumped $200. Turns out I was doing things like:Asking GPT-4 to write validation logic that Haiku could handle just fineSending full context windows when 30% of it was redundantRetrying identical requests with slightly different temperatu

📦 Service Workers in PWAs: How to Cache Content and Supercharge Web App Performance

Imagine this.You open a web app on a weak network. Instead of endless loading, it opens instantly. Pages feel smooth. Key content is available even offline. The experience feels closer to a native app than a traditional website.What changed?Behind the scenes, a quiet but powerful technology is doing the heavy lifting: Service Workers.If you’re building Progressive Web Apps (PWAs), understanding service workers can dramatically improve speed, reliability, and user experience.In this guide, you’ll

ReactJs Performance ~ Optimizing Images and Assets~

In typical React apps, images account for 50–70% of page weight. Properly optimising them can dramatically improve load times and user experience.Modern image optimisation checklist1.Use WebP/AVIF formats, which are 30-50% smaller than JPEG.2.Implement responsive images to serve the appropriate size.3.Lazy load off-screen images – defer non-critical images.4.Use modern image components such as Next.js Image or Gatsby Image.5.Use modern image components such as Next.js Image or Gatsby Image.6.Set

Stop Flickering UIs: Handle Subdomains with Next.js Edge Middleware ⚡

The Challenge of Dynamic SubdomainsWhen scaling a professional B2B SaaS platform at Smart Tech Devs, providing clients with their own custom subdomains (e.g., acme.smarttechdevs.in) is a premium feature that instantly elevates your brand. However, architecting this on the frontend can be complex. In a monolithic React app, you might find yourself writing messy `useEffect` hooks to parse the window.location.host and render different components based on the URL.This approach is slow, causes screen

Mastering Map and Set in JavaScript: Beyond Objects and Arrays

If you’ve been writing JavaScript for a while, you’re likely intimately familiar with Objects and Arrays. They are the bread and butter of data structures in JS. We use Objects to store key-value pairs and Arrays to store ordered lists. But as your applications grow in complexity, you might start hitting the inherent limitations of these traditional structures. Enter Map and Set—introduced in ES6 to solve the exact edge cases and performance bottlenecks that Objects and Arrays struggle with.Let'

Understanding JavaScript Promises: A Comprehensive Guide

JavaScript promises are a powerful feature that help manage asynchronous operations in a more readable and manageable way. In this article, we will explore the essential aspects of promises, including their lifecycle, how to handle success and failure, and the advantages they offer over traditional callback methods. What Problems Do Promises Solve?Promises address several key issues in asynchronous programming:Callback Hell: When multiple callbacks are nested, the code can become difficult
