Understanding HTTP Request Methods with Express.js

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

I’ve been rebuilding one of my personal projects with #Next.js and #TypeScript, and it’s been a great way to get a proper feel for how it works beyond plain #React. Over the last two weeks, I’ve been diving deeper into a few areas: ⏺️ File-based routing – creating routes by adding files and folders feels cleaner and straightforward than manually managing routes. ⏺️ <Link> and <Image> – these built-in components handle a lot behind the scenes. Links prefetch automatically, and images are optimised on the server. No more fiddling with lazy loading or formats. ⏺️ Fetching data from my own database – I’ve been handling data fetching inside server components using async functions, which lets me query data directly without setting up separate API routes. Still plenty to learn (and probably refactor 😆), but I’m starting to see why so many devs are working with #Next.js.

Why are you still using fetch in useEffect? Recently, while browsing through GitHub, I stumbled upon a repository that’s rapidly gaining momentum — a toolkit powerful enough to help you build entire systems. You probably know it already: TanStack. But before I go on… How are you fetching data in your React, Svelte, Vue, or Angular apps? Is your approach truly optimal? If you’re a React developer, chances are you’re still wrapping a fetch call inside a useEffect. But let’s think about that for a moment: • How are you handling API errors? Another useState to store error values? • How are you managing loading states while waiting for responses? • How do you keep your data fresh? • Do you re-fetch data that you fetched a few seconds ago? • How are you storing and synchronizing shared data? • Still stressing about global state? • What about managing mutations and keeping everything in sync with the server? It’s a lot. And it doesn’t have to be that way. You don’t have to shave with a razor blade when clippers exist. TanStack Query is the clippers. Traditional fetch + useEffect is the razor from 1920. Ever since I switched, the way I fetch and manage server data changed completely. Are you still using fetch + useEffect? What’s stopping you from switching?

🚀 Mastering res.on() Events in Node.js – The Hidden Power Behind Streams! Ever wondered how you can listen to the lifecycle of an HTTP response in Node.js? That’s where res.on() comes in — it lets you react to key response events such as when data is being sent, finished, or when something goes wrong. Let’s break it down 👇 🧠 What is res.on()? In Node.js, every HTTP response object (res) is an EventEmitter, which means we can subscribe to events like: 'data' → when data chunks are being written 'end' → when all data is sent 'error' → when something goes wrong during transmission 'close' → when the connection closes (even abruptly) This gives developers fine-grained control over network responses — a must for performance monitoring, debugging, and logging. 💡 Why Use res.on()? ✅ Monitor outgoing responses — useful for logging and analytics. ✅ Handle premature disconnects — detect if clients drop off. ✅ Improve debugging — get detailed insights into request/response flow. ✅ Enhance performance tracking — measure when responses actually complete. 🎯 Key Takeaway res.on() turns your Node.js responses into observable events — empowering you to build robust, reliable, and production-grade servers with deeper control over network behavior. #NodeJS #BackendDevelopment #WebPerformance #FullStackDevelopment #JavaScript #LearningInPublic

💡 React Tip of the Day! Ever faced this? 👇 Your child component triggers an API call, but you want to re-fetch the data after the parent completes some task — without moving all that logic up to the parent 😩 Here’s a simple, elegant trick 💫 Use the key prop to re-render the child! <ChildComponent key={refreshKey} /> Then in the parent: setRefreshKey(prev => prev + 1); 💥 Each time the key changes, React remounts the child component — triggering its useEffect (and your API call) again automatically. Why this rocks 🚀 ✅ No need to uplift or duplicate API logic ✅ Keeps child components self-contained ✅ Clean, predictable, and easy to manage A neat little trick to refresh data without refactoring half your tree! 😄 #ReactJS #WebDev #FrontendTips #CleanCode #ReactHooks

🚀 Just published a new technical article on real End-to-End testing in NestJS — no mocks, no shortcuts. I built a small open-source project showing how to use Vitest + PostgreSQL for fully-integrated E2E and integration tests, with Factory & Builder patterns to keep the setup clean and scalable. 💡 If you’ve ever wanted to go beyond unit tests and actually test your app the way it runs in production, this walkthrough is for you. 🔗 Medium article: https://lnkd.in/e2HiHq2b 💻 GitHub repo: https://lnkd.in/etkPGDRR] #nestjs #e2e #nodejs #vitest

𝐀𝐟𝐭𝐞𝐫 𝐜𝐨𝐦𝐩𝐥𝐞𝐭𝐢𝐧𝐠 𝐬𝐞𝐯𝐞𝐫𝐚𝐥 𝐛𝐞𝐠𝐢𝐧𝐧𝐞𝐫 𝐩𝐫𝐨𝐣𝐞𝐜𝐭𝐬, 𝐈 𝐟𝐞𝐥𝐭 𝐫𝐞𝐚𝐝𝐲 𝐭𝐨 𝐭𝐚𝐤𝐞 𝐚 𝐬𝐦𝐚𝐥𝐥 𝐬𝐭𝐞𝐩 𝐮𝐩. So I decided to try out my first intermediate project: 𝐚 𝐂𝐚𝐜𝐡𝐢𝐧𝐠 𝐏𝐫𝐨𝐱𝐲 ⚙️ The idea was simple: to build a CLI tool that forwards requests to another server, caches the responses, and serves the cached version when the same request is made again. When it displays 𝐌𝐈𝐒𝐒, it means the address is being accessed for the first time, while 𝗛𝗜𝗧 indicates the response is being returned from the cache. In short, it helps reduce the time needed to load a webpage or retrieve data, kind of like giving the server a short-term memory 🧠 Building it was surprisingly enjoyable. It felt like every project I’d done before was a stepping stone to this one. Not only did it refresh what I had already learned, but it also helped me dive deeper into concepts like: ⚡ How caching works and why it’s important for performance 🌐 How proxy servers forward and handle HTTP requests 🗄️ How to manage and clear cached data This project reminded me that 𝒇𝒖𝒏𝒅𝒂𝒎𝒆𝒏𝒕𝒂𝒍𝒔 𝒕𝒓𝒖𝒍𝒚 𝒎𝒂𝒕𝒕𝒆𝒓, they’re the foundation that makes tackling harder problems easier later on. It’s easy to overlook them, but they’re what keep everything else standing.

Understanding the Core of REST APIs — Every Developer Should Know This Whenever your frontend talks to your backend, it’s usually through a REST API. But what really makes an API RESTful? Here’s the breakdown: Representational State Transfer It’s all about how data travels between client and server. For example — when you make a GET request in your website, you’re just asking the server: “Hey, send me this data in JSON format!” REST APIs use simple HTTP methods like: GET → Retrieve data POST → Send data PUT → Update data DELETE → Remove data Once you truly understand this, backend development starts feeling much easier. #MERN #WebDevelopment #JavaScript #Backend #LearningInPublic #FullStackDeveloper #CodingJourney #TechConcepts

🚀 Understanding Streams and Buffers in Node.js Have you ever wondered how Node.js efficiently handles large files like videos, logs, or data transfers without running out of memory? 🤔 The answer lies in Streams and Buffers — the backbone of Node.js I/O operations. A Buffer temporarily holds chunks of binary data, while a Stream processes that data piece by piece instead of loading everything at once. This approach makes Node.js incredibly efficient when dealing with big files or real-time data. Whether it’s reading a large CSV, serving a video, or handling file uploads, Streams help you process data continuously and save resources. Once you master Streams and Buffers, you can build scalable applications that handle massive data effortlessly. ⚡ 💭 Have you ever worked with file streams or HTTP streams in your Node.js projects?
