You've thought about adding Bitcoin. Here's why you haven't done it yet.Every time you look into adding Bitcoin to your app, you hit the same wall: wallets, private keys, gas fees, node infrastructure, security audits.

We built this so you don't have toStarkzap is an open-source TypeScript SDK that lets any application (web app, mobile app, backend service) integrate Bitcoin with no blockchain expe

I Built a CAPTCHA Killer Using Behavioral Micro-Signals — Here's the Math Behind It

The ProblemCAPTCHAs are the worst UX on the internet. And now they don't even work.GPT-4V solves image CAPTCHAs with >99% accuracy. Google's reCAPTCHA is essentially a surveillance tool that tracks users across the web in exchange for "free" bot detection. And the $4.1B CAPTCHA industry has no answer.I decided to build something fundamentally different.The InsightWhen you interact with a device, your body produces involuntary micro-signals. Your hand trembles slightly (3-12Hz physiological tr

How to sort an array of objects in JavaScript?

Sorting an array of objects is something you’ll run into pretty often when working with JavaScript. This usually comes up when dealing with tables, lists, or data coming from an API.In this article, we’ll go through how to sort arrays of objects using JavaScript’s sort() method. We’ll focus on practical examples and common patterns you’re likely to use in real projects. Why Sorting Arrays of Objects MattersIn most applications, data doesn’t arrive in the order you want. API responses, datab

Migrating a Large App to the New React Native Architecture

The New React Native Architecture which combines Fabric with TurboModules and JSI will deliver improved application startup times and better animation performance and enhanced reliability of the connection between native code and JavaScript code. The process of migrating a complete production application requires more effort than simply using a switch to complete the task. In this post, I will present a complete guide which includes:The actual architectural differences which exist in the new sys

Building Real-Time Processing Status with Supabase Realtime

Elevating UX: Real-Time Processing Status with Supabase Realtime and ReactWe've all been there: staring at a spinning loader, wondering if a crucial background task in our application is actually making progress or if it's silently crashed. Whether it's a large file upload, a complex data migration, or generating an elaborate report, the absence of real-time feedback is a major source of user frustration and a silent killer of trust.In my experience, providing transparent, real-time proces

🔥 8 Essential Tools and Libraries That Every React.js Developer Should Know 🚀

React has been around for over ten years now, and thanks to its status as the most popular front-end framework, its ecosystem keeps growing and evolving. While React itself focuses just on the UI layer, most real world apps need more functionalities like data fetching, state management, form handling, animations, and routing. This is why a mature ecosystem matters, you don’t need to learn or code everything. There are many reliable and helpful tools that you can use right away.Here are 8 tools a

Vibe coding React Color Picker using Google Antigravity

I vibe-coded an MVP version of Color Picker this weekend for my ReactJS/NextJS projects using Google Antigravity. It was less of a self-test of JavaScript and more of a challenge to myself, to see if I can use Prompt Engineering to build something that is commonly used in my projects.After initial research, to make it framework independent, and to keep everything in Shadow DOM, I finalized using Lit, Open Web Components, and Rollup module bundler.

Why Enterprises Still Choose Sencha Ext JS Over Angular (Even in 2026)

Building a Shopify App That Actually Ships to Puerto Rico (Tutorial)

If you're building a Shopify store or app, there's a good chance your shipping configuration silently blocks 3.2 million potential customers in Puerto Rico.Here's how to fix it — and a real example of what breaks. The Default Shopify ProblemWhen you set up Shopify shipping, the default "Domestic" zone includes only the 50 US states. Puerto Rico gets lumped into... nothing. Or worse, "Rest of World."This means:PR customers see inflated "international" shipping ratesSome checkout flows reject

I Built a Privacy-First Image Compressor That Runs 100% in Your Browser

Every image compressor I tried had the same problem: they upload your photos to a server.TinyPNG? Server upload. Compressor.io? Server upload. iLoveIMG? Server upload.As a developer, this bothered me — especially when compressing client work, personal photos, or anything sensitive. Why should my images travel across the internet just to remove a few kilobytes?So I built ImgPakt — an image compressor that processes everything locally in your browser. Zero uploads. Zero servers. Your files never l

FULL-STACK IS DEAD. (Or Is It?)

The narrative is everywhere in 2026: “AI now owns the frontend.” “Backend is just serverless functions.” “True specialists are the future.”Yet step back and examine the actual landscape. Early-stage startups continue to prioritize engineers who can single-handedly own a feature from polished UI through secure logic, scalable APIs, and reliable cloud deployment. Product teams still hemorrhage time and capital on fragmented handoffs between narrowly focused frontend and backend specialists. The hi

expo-image-and-video-compressor vs react-native-compressor — Honest Comparison (2026)

If you're building a React Native app that handles user-generated media — profile photos, video messages, social posts — you need compression. Two packages compete for this space: react-native-compressor (the established player with ~80K weekly downloads) and expo-image-and-video-compressor (the newer Expo-native alternative).I built expo-image-and-video-compressor because I ran into real friction with the existing options. This post breaks down the honest differences — where each package wins,

Hi coders 👋,I recently built my own form validation library for React instead of using heavy libraries. I wanted something lightweight, flexible, and easy to control — so I decided to build it from scratch. Why Not Use Existing Libraries?While working with forms in React, I explored popular solutions. They are powerful, but I faced a few issues:Too much boilerplateLarge bundle sizeComplex configuration for simple formsLimited flexibility for custom validation logic** Install first pack

Industrial Specifications and Sourcing Insights for Brass Round Bar and Carbon Steel Round Bars

Round bar materials find a prominent place in mechanical fabrication, fastener production, and structural assemblies owing to the consideration of their machinability and load-bearing properties. In valve stems, marine hardware, and precision-turned components, the Brass Round Bar is most frequently offered in main alloys such as ASTM B16 C36000 free-cutting brass, C26000 cartridge brass, and C28000 Muntz metal, complying with the ASTM and EN standards. Diameter sizes usually vary from 5 mm up t
