Master Node.js Core Modules for Backend Development

As a Node.js developer, there’s absolutely no need to keep deleting and reinstalling Node every time a project requires a different version. The smarter way? 👉 Use NVM (Node Version Manager). With NVM, you can: 🔁 Switch between Node versions instantly ⬆️ Upgrade or downgrade to the most stable version for your dependencies 🧪 Test projects on different Node environments without breaking your system 🧹 Keep your development setup clean and conflict-free Different projects, different requirements — and that’s okay. One project may work perfectly on Node 16, another needs Node 18 or 20. NVM lets you handle all of that effortlessly. If you’re still uninstalling Node manually, you’re making development harder than it needs to be. Work smarter, not harder. Master your tools — they matter more than you think. #NodeJS #JavaScript #WebDevelopment #BackendDevelopment #SoftwareEngineering #Developers #TechTips #CodingLife #DevCommunity #Programming

Day 28 of making my self a BRAND 1 . Learned how Next.js Proxy (formerly Middleware) works perfectly even when backend is completely separate Node.js server super clean auth & redirect logic! 2 . Understood that there's only ONE proxy.ts file allowed (root or src folder) no multiple middleware files, keeps everything organized. 3 . Discovered best practice: Keep Proxy super fast & lightweight (only checks), never do heavy database/auth logic here always call separate backend API. 4 . Mastered matcher config to protect all routes except static files & API paths perfect security + performance balance for production apps. 6 . Realized Proxy runs on every Next.js domain request (pages, not backend APIs) game-changer for auth, headers, A/B testing when backend is decoupled! #NextJS #Nextjs16 #ReactJS #JavaScript #WebDevelopment #FrontendDevelopment #FullStack #NodeJS #TypeScript #SoftwareEngineering #Tech #Developer #Programming #Code #LearnToCode #WebDev #DevCommunity #100DaysOfCode #TechTwitter #SoftwareDeveloper #NextjsTips #Middleware #Proxy #Authentication #Security #BestPractices #CleanCode #Frontend #Backend #DecoupledArchitecture #Vercel #ReactDev #JavaScriptDeveloper #CodingLife #TechTips #DeveloperCommunity #OpenSource #BuildInPublic #CareerGrowth #TechJourney #CodingJourney #SelfBranding #PersonalBranding #LinkedInLearning #DeveloperLife #CodeNewbie #WomenWhoCode #BlackTechTwitter #TechPakistan #PakistanTech

Recently completed a full-stack implementation focused on production-grade authentication and system design using Django REST Framework and React. Key learnings from this project: -Designing stateless authentication using JWT with short-lived access tokens and long-lived refresh tokens -Securing APIs through layered authorization (public vs protected routes) -Handling token expiration using a centralized refresh strategy rather than manual re-authentication -Implementing Axios interceptors to transparently retry failed requests after token renewal -Managing global authentication state using React Context to keep UI and routing in sync -Structuring frontend–backend communication to be scalable, maintainable, and decoupled -This project helped me move beyond basic login flows and understand how authentication, authorization, and token lifecycle management are handled in real-world systems. It also reinforced the importance of separating concerns and centralizing cross-cutting logic like authentication.

🚀 Just shared a concise guide on Express.js Middleware — covering what middleware is, how next() works, common types, error handling, and real-world use cases. Perfect for backend developers looking to write cleaner, scalable APIs with Node.js. #ExpressJS #NodeJS #BackendDevelopment #JavaScript #WebDevelopment #APIDesign #Middleware #FullStack #Programming

Leaving the localhost/prototype phase and moving into real MVP deployments. https://lnkd.in/eExw6AXv C# Adventure is an interactive platform to learn C# and OOP through practical challenges, code execution, and progress tracking. More than the product itself, the focus was on building something real, with technical decisions, trade-offs, and genuine production problems. From a technical standpoint, the project includes: • Microservices architecture (Auth Service + Lesson Service) • Backend: Java, Spring Boot, Spring Security, JWT • Frontend: Vue.js, Vite, Tailwind CSS • REST APIs with access control and business rules • PostgreSQL + JPA/Hibernate • Docker for environment standardization • CI/CD pipelines for build and deployment • Cloud deployment with services running in production • Automated tests for controllers and services There is still a lot to build (a payment integration service, for example), A lot of links to connect, but I was anxious to share what I’ve been working on so far. In the bottom-right corner, there is a button to report bugs in case you have a few minutes to take a look. And we keep going, always building. #Java #Vue #Docker

🚀 90 Days of Node.js Challenge – Day 12 Today I explored the File System (fs) Module in Node.js, an essential concept for backend development. 📂 The fs module allows us to read, write, update, and delete files efficiently, helping applications interact with the system in real-world scenarios like logging, data storage, and configuration handling. 🔑 What I learned today: ✅ Difference between synchronous and asynchronous file operations ✅ Reading and writing files using fs.readFile() and fs.writeFile() ✅ Appending and deleting files ✅ Creating and removing directories 📌 Key takeaway: Asynchronous file handling is crucial for building high-performance, non-blocking Node.js applications. 📈 Consistency beats intensity — one day at a time! #NodeJS #90DaysOfCode #BackendDevelopment #JavaScript #WebDevelopment #LearningJourney #CodingChallenge

When I start a new project for my clients, I usually use NestJS to build an MVP. Once the project grows, I switch to a multithreaded language with a scalable framework (Spring Boot, Actix Web, Gin, .NET, etc.) and proper orchestration to ensure the service can handle increasing traffic. It doesn’t matter which technology you use; what matters is the results. You can never be 100% sure a project will succeed, which is why you shouldn’t put all your effort in at the beginning. Instead, focus on the fundamentals (security, availability, maintainability, etc.). When the project grows, then jump to the next level 👌🏽 #softwareEngineer #nestjs #springboot #java #golang #rust

Forget the browser. I built my portfolio in the terminal. 🖥️ As I dive deeper into Systems Engineering and GoLang this winter, I realized a standard React website didn't reflect who I am as an engineer anymore. So, I built a fully interactive portfolio accessible via SSH. How it works: This isn't just a script running on a Linux box. It’s a custom SSH server written in Go that serves a TUI (Text User Interface) application directly to your terminal. The Tech Stack: 🔹 Backend: Go + Charm’s Wish library (Custom SSH Server). 🔹 Frontend: Bubble Tea (The ELM architecture for terminals). 🔹 Styling: Lip Gloss (for the layouts and borders). 🔹 Infrastructure: Dockerized and deployed on Azure. The best part? It’s lightweight, instant, and requires zero HTML, CSS, or JavaScript. Check out the demo below 👇 Try it yourself: ssh dev.tarunnayaka.me (Port 22) check my portfolio : tarunnayaka.me #GoLang #SystemsEngineering #BubbleTea #SSH #CloudNative #WinterArc #Engineering

🚀 Just built Jarvis — a robust Discord Automation Bot! 🤖 I developed this to solve two problems: Server Security and Vocabulary Building. Top Features: 🛡️ Auto-Moderation: Instantly kicks toxic users to keep the community safe. 📖 Smart Dictionary: Uses a dual-API fallback system for 99% word coverage. 🔤 Vocab Builder: Dynamic !word command for daily learning. Tech Stack: Node.js | Discord.js | Axios | REST APIs Proud to showcase my progress in backend automation. source code -> https://lnkd.in/gWx5mxeF #NodeJS #DiscordJS #Automation #Javascript #Backend #SoftwareDevelopment #Programming
