Skill Boosters — Notes #9: Node.js V8 Engine & Microservices 🔗 Read full article: https://lnkd.in/gV87EbEC Ever wondered why Node.js is so fast? 👇 V8 Engine - Converts JavaScript → Machine Code - Executes it super fast Microservices - Break app into small services - Each service works independently Why this matters? ✔ V8 → Speed ✔ Microservices → Scalability Real Meaning Fast execution + Scalable system = Powerful backend architecture One Line Takeaway: Node.js + V8 = Speed | Microservices = Scale What do you prefer: Monolith or Microservices? #NodeJS #Microservices #BackendDevelopment #JavaScript #SystemDesign

NODE.JS — PART 3 (HTTP Server & APIs) This is where Node.js becomes practical. In this post: • Creating a basic HTTP server • Understanding request (req) and response (res) • Handling routes • Building simple APIs • Sending JSON data This is the foundation of backend development, because APIs are what connect frontend applications to data. Understanding this flow makes it easier to build full-stack applications. 📌 Save this for revision. #NodeJS #BackendDevelopment #WebDevelopment #JavaScript #FullStack #APIs #LearningInPublic #Consistency

Lately I’ve been spending some time digging deeper into TypeScript for backend development with Node.js. One thing that really stands out is how much easier it becomes to refactor code when a project starts growing. Having clear types across services and data structures removes a lot of the guesswork when changing things. Instead of hoping nothing breaks, the compiler usually tells you exactly what needs attention. It also makes the code easier to understand when multiple developers are working on the same system. At first TypeScript can feel like an extra layer on top of JavaScript, but once the codebase gets bigger it starts to feel more like a safety net. #typescript #nodejs #softwareengineering #backenddevelopment #fullstackdeveloper #remotedeveloper #globaltech

Completed Episode 3 " Creating Our Express Server " of Namaste Node.js season -2 #NamasteNodejs by getting started with backend development means understanding how a server runs, how dependencies are managed, and how tools simplify your workflow. 📦 Express.js A fast and minimal framework used to build web servers and APIs in Node.js. Simplifies routing, request handling, and middleware usage. Widely used for scalable backend applications. 🌐 app.listen() Method used to start the server and make it listen for incoming requests. Binds the server to a specific port number. Essential for making your application accessible. 📁 node_modules Folder Contains all installed dependencies required for the project. Automatically generated when installing packages. Usually excluded from version control (Git). 📜 package.json Core file that stores project details and configurations. Manages dependencies and scripts. Helps in sharing and maintaining the project setup. 🔒 package-lock.json Locks the exact versions of installed dependencies. Ensures consistent installs across different environments. Automatically generated and maintained by npm. ⚡ Nodemon Tool that automatically restarts the server on file changes. Improves development speed and efficiency. Commonly used during development, not in production. #BackendDevelopment #NodeJS #ExpressJS #WebDevelopment #FullStackDeveloper #SoftwareEngineering #APIDevelopment #JavaScript #Programming #Coding #Developer #CodeNewbie #LearnToCode #Tech #100DaysOfCode #SystemDesign #BackendEngineer #WebDev #DevCommunity #SoftwareDeveloper #CodingJourney #TechContent #BuildInPublic #DevelopersLife #CodeDaily #ProgrammingLife #NodeDeveloper #ExpressServer #APIs #ServerSide #NPM #OpenSource #TechEducation #Akshaysaini #Namastenodejs #NamasteDev

Stop defaulting to Node.js for every new microservice without testing the alternatives. 🛑 Don't get me wrong, Node is incredibly reliable. But after heavily experimenting with Bun in my recent TypeScript backend architectures, the developer experience and sheer speed are hard to ignore. Here is why my perspective on JavaScript runtimes is shifting in 2026: 1. Out-of-the-box TypeScript: No more wrestling with ts-node, nodemon, or complex build steps just to get a basic Express server running in development. Bun executes .ts files natively. 2. The Installation Speed: Running bun install versus npm install feels like upgrading from dial-up to fiber optic. In a CI/CD pipeline, those saved seconds per build add up to massive cost and time savings. 3. The All-in-One Toolkit: Having the runtime, package manager, and test runner bundled into a single incredibly fast binary reduces toolchain fatigue. While I still rely heavily on the robust Node ecosystem for legacy enterprise systems, Bun is quickly becoming a serious contender for new, lightweight microservices where performance is non-negotiable. Backend engineers: Are you still strictly starting new projects with npm init, or has your team started migrating towards faster runtimes?

New blog is live! 🚀 Under the guidance of Hitesh Choudhary Sir and the Chai Aur Code team, I’ve published “Blocking vs Non-Blocking Code in Node.js” — a clear explanation of what blocking and non-blocking mean, why blocking slows servers, and how async operations help Node.js stay fast. If you’re learning backend development, this one is a great read. Read it here: Blocking vs Non-Blocking Code in Node.js What should I write next — event loop, async/await, or file system operations? 👇 https://lnkd.in/ddS_-PvA #NodeJS #AsyncProgramming #BackendDevelopment #JavaScript #BlogPost #chaicode

NodeJS - Session - 7 Most Node.js projects don’t fail because of code… They fail because of **poor configuration management**. 🔐 **Environment & Config in Node.js (Done Right)** 👉 **.env Files** * Keep secrets out of code * Store environment-specific values (dev, test, prod) * Simple, but powerful when used correctly 👉 **Config Management** * Centralize all configs (no scattered values) * Use environment-based configs (`development`, `production`) * Access via `process.env` with proper fallbacks 💡 **Real Best Practices** * Never commit `.env` to Git * Validate env variables at startup (fail fast) * Use different `.env` files per environment * Keep configs clean, predictable, and centralized ⚠️ Reality check: `.env` solves structure… not safety. Without validation + control, misconfigurations still break production. 👉 Strong systems don’t just run on code — they run on **well-managed configuration**. #NodeJS #BackendDevelopment #CleanCode #SoftwareArchitecture #DevBestPractices #JavaScript

I kept rebuilding the same Node.js backend setup for every project — so I decided to automate it. Instead of doing it again, I built a CLI tool to solve it. It creates a Node.js backend in seconds — with Express, MongoDB, and a clean structure ready to go. Command: npx create-temaplate-backend project-name --- 🔗 npm: https://lnkd.in/ehY8UjQv 💻 GitHub: https://lnkd.in/euy3SshN --- Still improving it step by step. If you’ve built backend projects before, what features would you expect in a tool like this? #nodejs #javascript #developers #learninginpublic
