React Forms Simplified with Server Actions

Why does an uncaught exception crash a Node.js server? It's common in asynchronous callbacks and functions that have no exception handling. During the process, the async callback is pushed to the event queue and gets executed. If it doesn't have any try/catch surrounding an exception, it's on its call stack. If an error is thrown in this case, it will be moved to the top of the event loop tick. As the error is unhandled in an async context, Node considers the app to be unstable and terminates the process with a non-zero error code. Node.js takes this decision because, as the event loop is single-threaded, there is no higher context to return from. And continuing might lead to unknown issues. So, it is better to terminate the process. Even if calling a function is wrapped with try/catch, it won't help, as that operates in a different call stack. However, Node.js emits a special event, uncaughtException, which can be used to log the reason. Cheers! #nodejs #backend #javascript #server

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.

Most form validation bugs I've seen in production weren't in the frontend. They were on the server, where nobody was actually validating anything. Here's a pattern I use in every Next.js project now: pair Server Actions with Zod for full-stack, type-safe validation in one place, zero duplication. The idea is simple. Define your Zod schema once. Use it directly inside the Server Action. If validation fails, return typed errors back to the client. If it passes, proceed to your database layer. TypeScript types flow end-to-end without any manual sync between client and server schemas. No separate API route. No duplicated logic. No guessing what shape your errors will be in. This pattern shines especially with Supabase and Prisma, define the schema once, validate at the boundary, and fully trust the data that reaches your ORM. Sounds obvious. But I've seen too many Next.js codebases where the client validates, the server trusts, and production catches the gap.

🚀 Day 1 of Backend Journey — Serving Static Files in Express.js Today I learned how to serve static files like HTML, CSS, JavaScript, and images using Express.js. 📁✨ 🔹 Key Learnings: - What static files are and why they matter - Using "express.static()" middleware - Organizing assets inside a public folder - Linking static files with EJS templates 💡 Insight: Serving static files efficiently improves performance and reduces server load, making applications faster and more scalable. 📌 Every small concept is a step toward becoming a better backend developer! #BackendDevelopment #NodeJS #ExpressJS #WebDevelopment #LearningJourney #100DaysOfCode

Your React component is leaking memory and you have no idea. I just read about this pattern in the docs. I realized I was fighting the React lifecycle for months 😅 The problem? Race conditions from uncleared async requests. When you fetch data on state change: - User changes profile 10 times in 1 minute - 10 API requests fire - Only the LAST response updates state - Previous 9 complete but state is already changed - Memory leak + stale data Most devs skip cleanup. Most tutorials show incomplete examples. Result? Wasted requests, stale data, memory leaks. #React #JavaScript #Performance #WebDevelopment

⚛️ Hey devs — are we overcomplicating React in 2026? I see many developers still adding heavy state management libraries in every project… but do we really need them anymore? Let’s be honest 👇 👉 With modern React: Server Components handle most data fetching Hooks manage local state efficiently Context is good enough for many global cases So why are we still doing this? ❌ Adding Redux for small apps ❌ Managing state that could live on the server ❌ Overengineering simple flows 💡 Here’s how I think about it now: Server → data & logic Client → interaction State → keep it minimal ⚡ Real talk: Most “state problems” are actually architecture mistakes. If your state is growing too much… maybe it shouldn’t be on the client at all. Curious — how are you managing state in your projects these days? #reactjs #nextjs #frontend #webdevelopment #statemanagement #javascript #softwareengineering #performance

7 Next.js features I wish I knew earlier: Image component — automatic optimization, zero effort Dynamic imports — load heavy components only when needed Middleware — intercept requests before they hit your page Server components — fetch data without useEffect chaos Parallel routes — render multiple pages simultaneously Route handlers — bye bye separate backend for simple APIs Built-in analytics — performance insights out of the box I was writing 3x more code before I discovered half of these. Which one changed your Next.js game the most? #Nextjs #ReactJS #WebPerformance #FrontendTips #JavaScript

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.

🚀 My Bug Tracker project is now live. I built this full stack application using ASP.NET Core Web API for the backend and React + TypeScript for the frontend, and it is now deployed and working in production. It includes JWT authentication, protected routes, CRUD operations for projects and issues, filtering, search, pagination, and a responsive UI for both desktop and mobile. 🔗 Live Demo: https://lnkd.in/enRSkrQX 🔗 Backend Repository: https://lnkd.in/eBjD295S 🔗 Frontend Repository: https://lnkd.in/e66nk76i 🔗 Backend API: https://lnkd.in/ebTfyaGx This project helped me reinforce both practical backend concepts and the process of taking an application from development to deployment. Now that it is live, my next focus is on interview preparation and strengthening the fundamentals behind the stack I used. #SoftwareDevelopment #BackendDevelopment #CSharp #DotNet #ReactJS #PostgreSQL #TypeScript #JuniorDeveloper #LearningInPublic

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
