Node.js 22 Performance and Utility Enhancements: Features You Should Be Using Node.js 22, now in Long-Term Support (LTS), ships with V8 12.4, which includes the Maglev compiler for faster execution of JavaScript code. This release also brings support for new ECMAScript features and improvements to the core runtime. Key language features include new array methods like Array.prototype.with() and Array.prototype.toSorted(), and the RegExp v flag for improved regular expression capabilities. Node.js 22 also enhances WASI (WebAssembly System Interface) support, allowing for the secure and efficient integration of compiled languages like Rust and C into Node.js workloads.

⚒️ Built a React Folder & File Tree. Built with the tree data structure. Let's dive in! A demo that models a file system in React. You can add folders/files, rename inline, nest children, expand/collapse and watch the JSON tree update as you go. Tech Stack ✅ React 19 (Hooks) ✅ TypeScript ✅ Vite (dev/build) ✅ Tailwind CSS (minimal UI) Key Features 🔹 Add folders/files at root or inside any folder 🔹 Inline rename (click → edit → Enter/blur) 🔹 Expand/Collapse + quick per-node controls 🔹 Delete nodes safely 🔹 Stats for folders/files + empty state 🔹 Live JSON Tree Inspector for learning/debugging ⚠️ Note: It’s intentionally simple and teachable (an educational demo), not a full filesystem or virtualized tree. Ideas and PRs welcome! Check it out: 🔗 Live Demo: https://lnkd.in/ebWQ9Xb6 💻 Source: https://lnkd.in/er8N38fK Useful?

What a ride! Just deployed my latest full-stack app, and honestly, the real win wasn't just the code, but the journey to get it live. 😅 This project was a deep dive into building a robust School Management Portal using Next.js and MySQL. It tested everything from frontend design to tricky server configurations. 🏆 My Top 3 Learning Takeaways: Backend is King (and Tricky!): Building Next.js API Routes and connecting them directly to MySQL (CRUD) was the core challenge. I learned firsthand the mechanics of server-side file upload logic and managing persistent data—no magic, just pure backend engineering. The DevOps Struggle is Real: Getting the code from local machine to Vercel was the biggest fight. I had to troubleshoot persistent Git/GitHub authentication issues and solve critical Vercel build failures caused by incorrect file types and dependencies. Lesson learned: Deployment is half the battle! Frontend Polish Matters: Used Tailwind CSS and React Hook Form to build a responsive, professional-looking dashboard (loved playing with that dark theme inspired by OpticOdds!). Form validation was key to making the UX smooth. The app is fully functional on localhost. The connection errors on the live demo are a good reminder of the difference between local MySQL and cloud-hosted data. Thanks for all the resources and guidance that helped me cross the finish line! 🔗 Check out the code (GitHub): https://lnkd.in/gyTpFX29 🔗 See the live UI (Vercel): https://lnkd.in/gqhSzAZ3 #FullStackDeveloper #NextJS #Backend #MySQL #Deployment #ProblemSolving #WebDevelopment

💡 structuredClone() vs JSON.parse(JSON.stringify()) Both are used for deep copying objects in JavaScript, but they’re not the same. 🧠 structuredClone() Creates a true deep copy (recursively copies nested data). Supports complex types: Date, Map, Set, Blob, etc. Handles circular references safely. Faster and more reliable. const clone = structuredClone(obj); ⚠️ JSON.parse(JSON.stringify()) Works only for simple JSON-safe data. Loses functions, Dates, Maps, Sets, and Symbols. Crashes on circular references. ✅ Use structuredClone() whenever available (modern browsers & Node 17+). Use the JSON trick only for plain, simple data. #JavaScript #WebDevelopment #Frontend #DeepCopy #CodingTips

What I Learned After Building Dozens of Side Projects (Mostly By Accident) Over the past few years, I’ve built a surprising amount of projects. Not all of them shipped. Some turned into real tools people use. Some became prototypes. Some died halfway through because I lost interest. But I noticed certain patterns — lessons that kept repeating no matter what I was building. These are the things I wish someone had told me much earlier. Almost every time I got stuck, the solution wasn't a new library or pattern. It was something much simpler: Rename a confusing variable. Write the UI state in one place instead of six. Remove a layer of abstraction that didn’t help. Make the flow explicit instead of “smart.” Code that is easy to understand is code you actually want to work on. I’ve built projects in: Next.js Vite + React Electron Supabase MySQL Node APIs Rust experiments The takeaway wasn’t “use Stack X.” It was: Pick the stack that makes the next step easy. If the framework gets in the way, it’s the wrong framework for this project, even if it’s technically “bet https://lnkd.in/gEz2BJkW

⚛️ When I finally stopped my React component from doing unnecessary math 😅 I was building a dashboard where a small counter update caused my entire expensive calculation to re-run — every. single. time. 🤯 Even though the input didn’t change, React was recalculating it again and again. My poor CPU was screaming! 💻🔥 That’s when I discovered useMemo() — the performance lifesaver I didn’t know I needed. Here’s what I learned 👇 ❌ Before: function Dashboard({ data }) { const total = heavyCalculation(data); return <h1>Total: {total}</h1>; } ✅ After using useMemo(): function Dashboard({ data }) { const total = useMemo(() => heavyCalculation(data), [data]); return <h1>Total: {total}</h1>; } 💡 What useMemo() does: It remembers the result of your calculation until its dependencies change. If nothing changes, it just returns the cached value — no more re-running heavy logic! 🚀 ✨ Lesson learned: Use useMemo() when your function is expensive and your inputs don’t change often. React will thank you with smoother performance! 🙌 #ReactJS #useMemo #ReactHooks #FrontendDeveloper #MERNStack #PerformanceOptimization #WebDevelopment #JavaScript #LearningByDoing #CodingJourney

Remember when every API started with a controller folder? Those days might be numbered. Hono's documentation has a bit of a silent killer in its best practices which make it clear: they don't belong in modern JavaScript apps. It's an interesting stance. Controllers used to feel like the gold standard for structuring HTTP logic. They brought order, separation, and a sense of architecture. But maybe that era's ending? In Conversation Piece's debut alongside the Hustle Hammer series, I dig into whether the controller pattern still earns its keep in 2025 - or if frameworks like Hono are showing us a better way to think about routing and request handling. Give it a read and tell me where you stand: are controllers still part of your toolkit, or are you moving on? https://lnkd.in/e8tNRsYw

💻 It all started with a simple frustration... Every time I worked with APIs, I’d end up copying messy JSON into random online formatters — Some were slow, others spammed me with ads, and a few even sent data to their servers. One day, while debugging a client’s API, I thought — “Why am I trusting sensitive data to some random site?” That’s when I decided to build my own solution. 🔥 JSON Formatter Online — a free, privacy-friendly, and super-fast JSON formatter built for developers who value speed and simplicity. ⚡ Instantly formats and validates JSON 🔒 Runs 100% in your browser (no uploads!) 🧩 Clean, ad-free UI 🌗 Dark mode for late-night debugging I didn’t plan to launch it publicly at first—it was just a side project to make my own workflow faster. But when I shared it with a few dev friends… they started using it daily. Now it’s live for everyone. → https://lnkd.in/geiMP6qy Here’s what it looks like 👇 (attach your screenshot image here) Next up, I’m planning: JSON → CSV converter Shareable links Auto error detection Sometimes the best tools are born out of personal pain.
