Node.js Uncaught Exceptions Crash Servers

Node.js 25 just dropped and the changelog is… a lot. 😅 V8 14.1 for faster JSON, a new `--allow-net` permission flag for better security, Web Storage enabled by default, and a bunch of deprecated APIs that are officially gone. If you're planning an upgrade, there are a few breaking changes you need to check BEFORE you update. I broke it all down in plain English so you don't have to stare at the release notes. 👇 Read the full breakdown at hamidrazadev.com 🔗 #nodejs #javascript #webdevelopment #backend #nodejs25 #devblog #hamidrazadev

Did you know React forms changed forever? I spent 6 months building API routes for every form. Then Server Actions dropped - my entire workflow shifted overnight. Here's what changed: Before: Form → API route → validation → database → response  After: Form → Server Action → done. No middleware. No endpoints. No boilerplate. I shipped a user registration flow in 45 minutes last week. It used to take me half a day - big difference. Magic? Server Actions run directly on the server. You write one function. React handles the rest. That's it. No fetch(). No API folder. No context switching. My builds are faster. My code is cleaner. My deployments are simpler. This isn't just a feature update - it's a complete rethink of how forms work in React. What's the most tedious part of your current form workflow? ♻️ Repost if you're tired of building API routes for simple forms. #React #WebDevelopment #JavaScript #NextJS #ServerActions

Ever notice your search bar firing an API call on every keystroke? Type “react” and that’s 5 requests. Type a sentence and your network tab cries. The fix is a tiny React hook called useDebounce. It waits until the user stops typing, then returns the final value. One render. One request. Done. No libraries. No dependencies. Drop it into any search input, filter, or autosave field.

🛡️ Day 9 of 30 — Middleware in Next.js Most devs don't touch middleware until they need it. That's a mistake. It's one of the most powerful features in Next.js. What is Middleware? Middleware runs before a request is completed — at the edge, before your page or API route even loads. You can use it to: ✅ Redirect unauthenticated users ✅ Rewrite URLs dynamically ✅ Set/read cookies & headers ✅ Protect routes globally The basics: // middleware.ts (root of your project) import { NextResponse } from 'next/server' import type { NextRequest } from 'next/server' export function middleware(request: NextRequest) { const token = request.cookies.get('token') if (!token) { return NextResponse.redirect(new URL('/login', request.url)) } return NextResponse.next() } export const config = { matcher: ['/dashboard/:path*', '/profile/:path*'], } Key things to know: 🔹 File must be named middleware.ts at the project root 🔹 matcher controls which routes it runs on — be specific! 🔹 Runs on the Edge Runtime — no Node.js APIs like fs 🔹 Use NextResponse.redirect(), .rewrite(), or .next() Pro tip: Don't put heavy logic in middleware. Keep it fast — it runs on every matched request. Auth guards, A/B testing, locale redirects — middleware handles all of it before the page loads. 🚀 What are you using middleware for in your projects?

🚀 npm vs npx — Do You Really Know the Difference? If you're working with Node.js, understanding the difference between npm and npx can save you time and improve your workflow. 🔴 npm (Node Package Manager)
👉 Used to install, manage, and maintain packages
👉 Stores dependencies in node_modules
👉 Best for long-term project dependencies 🟢 npx (Node Package Execute)
👉 Used to run packages instantly without installing
👉 Executes CLI tools directly
👉 Perfect for one-time usage or quick testing 💡 Key Insight:
Use npm when you need it forever, and npx when you just need it now. 📌 Example: * npm install create-react-app → installs package * npx create-react-app my-app → runs instantly without install 🔥 Pro Tip:
npx comes bundled with npm (version 5.2+), so you already have it! 💬 Which one do you use more in your daily development — npm or npx? #NodeJS #JavaScript #WebDevelopment #Frontend #Backend #FullStack #CodingTips #Developers #TechLearning #ReactJs

⏳ 9 years. That's how long it took JavaScript to admit that new Date() was broken. Temporal just reached Stage 4. It's officially in ECMAScript 2026. Already shipping in Firefox and Chrome. TypeScript 6.0 includes the types. V8 14.4 turned it on by default, which means the next Node.js major gets it native with no flag. 🔥 Why this matters JavaScript Date has been a joke since 1995. Month indexes start at 0. Mutation everywhere. No time zone support. DST math that silently lies to you. Every team has written a Date wrapper at 2am. Every project pulls in a 70KB date library. That era is ending. 🧠 What Temporal gives you • Immutable date/time objects. No more accidental mutations. • Built-in time zones. Real zones, not offsets. DST-aware arithmetic that works. • Clear separation of concerns: PlainDate, PlainTime, PlainDateTime, ZonedDateTime, Instant, Duration. Each type means one thing. • Non-Gregorian calendars supported natively. • No more "is this UTC or local?" guessing game. Before: const meeting = moment.tz("2026-05-03 10:00", "Europe/Paris"); const inNY = meeting.clone().tz("America/New_York"); After: const meeting = Temporal.ZonedDateTime.from({ year: 2026, month: 5, day: 3, hour: 10, timeZone: "Europe/Paris" }); const inNY = meeting.withTimeZone("America/New_York"); No clone. No mutation. No surprises. ✅ What you can delete from package.json • moment (deprecated for years, still installed everywhere) • date-fns (for most cases) • luxon • dayjs • that custom Date helper nobody wants to own Keep them if you ship to browsers older than 2025 or Node older than 26. Everywhere else, start migrating. What library are you killing first - moment, date-fns, or that hand-rolled Date util in your repo? 👇 #javascript #typescript #nodejs #ecmascript #temporal #webdev #frontend #backend #tc39 #fullstack

Inspired by the book by James Smith, I have successfully built a Custom Web Server from scratch in Node.js! This was not about using Express or other high-level frameworks. This server was built using only the Node.js net module, directly on top of raw TCP sockets. What did I learn in this deep dive? ✅ How TCP sockets and the event loop really work. ✅ The anatomy of the HTTP protocol—from parsing requests to crafting responses. ✅ Implementing Chunked Transfer Encoding for memory-efficient file streaming. ✅ Upgrading an HTTP connection to a WebSocket for full-duplex, real-time communication. Building this server provided a profound understanding of what happens "under the hood" between a browser and a server. It was a challenging yet incredibly rewarding experience that truly sharpened my low-level understanding of web technologies.

Can you run a pure JavaScript WebRTC setup? Not just the client side getUserMedia() but actual ICE STUN and TURN servers.. I'd been thinking about this for a while and a recent conversation brought it back to mind. So I decided to give it a go. node-rtc implements the core WebRTC stack in Node.js with ICE STUN TURN and signaling. I'm not really sure what I'll do with it but I guess it's one step closer to building mesh networking into my app. 😁 https://lnkd.in/eKfZxuQa #WebRTC #JavaScript #NodeJS
