Boost Node.js Performance with Parallel API Calls

🚀 Node.js is single-threaded… so how does it handle thousands of requests at the same time? I recently explored the Node.js Event Loop and it completely changed how I understand backend performance. Here’s a simple breakdown: ✔ Timers → Executes setTimeout / setInterval   ✔ Pending Callbacks → Handles system callbacks   ✔ Poll (⭐ most important) → Processes I/O events   ✔ Check → Executes setImmediate   ✔ Close Callbacks → Cleanup phase  💡 The real magic happens in the “poll” phase. While working on backend APIs, I often used async/await but never fully understood what happens internally. This cleared a lot of confusion. 🔗 Read the full article here: https://lnkd.in/dTtFG6SF Have you explored the event loop deeply? #NodeJS #BackendDevelopment #JavaScript #FullStack #WebDevelopment

🚀 Event Loop in Node.js — The Reason Your API Is Fast (or Slow) Node.js is fast… But only if you understand the Event Loop. If not 👇 👉 Slow responses 👉 Delayed requests 👉 Poor performance 😐 🔹 What is Event Loop? It handles all async operations in Node.js Single thread Non-blocking Processes tasks in phases 🔹 Common mistakes ❌ Blocking code (sync functions) ❌ Heavy computation in main thread ❌ Large loops / CPU-heavy tasks ❌ Ignoring async patterns ❌ Poor promise handling 🔹 What experienced devs do ✅ Use async/await properly ✅ Break heavy tasks into smaller chunks ✅ Use Worker Threads for CPU tasks ✅ Use queues (Bull, RabbitMQ) ✅ Monitor event loop lag ⚡ Simple rule I follow If Event Loop is blocked… Everything is blocked. Node.js doesn’t scale by threads… It scales by non-blocking design. Have you ever faced event loop blocking issues? 👇 #NodeJS #BackendDevelopment #JavaScript #API #EventLoop #WebDevelopment

The Complete React Guide (2026 Edition) offers a comprehensive roadmap for mastering the React ecosystem, covering everything from fundamental principles to expert-level architecture. Key topics include: - The declarative nature of the library - Utilization of the Virtual DOM - Essential JSX syntax for building components The guide also delves into intermediate subjects such as: - Advanced hooks - Global state management via the Context API or external libraries like Zustand - Robust testing strategies Additionally, it explores performance optimization techniques, including memoization and lazy loading, as well as modern server-side rendering with Next.js. This resource is invaluable for anyone looking to deepen their understanding of React. #ReactJS #WebDevelopment #Frontend #JavaScript #ReactServerComponents #errorsoverflow

🧠 Dev Tip #2 – Lightweight Global State Instead of using heavy state libraries, I often use Zustand for global state. Why I like it: ✔ Minimal boilerplate ✔ Simple API ✔ Works great with React and Next.js Example use cases in my projects: • Auth state • Call state • Shared UI state across dashboards Simple and powerful. Sometimes the best tool is the simplest one. #reactjs #zustand #javascript #frontenddeveloper #webdevelopment

Ever wondered how Node.js works behind the scenes? 🤔 In my latest blog, I broke down Node.js internals in a simple way — focusing on the 3 core components: 🔹 V8 Engine (executes JS & manages memory) 🔹 Libuv (handles async tasks & event loop) 🔹 Bindings (connects V8 with system-level operations) Understanding this flow really changes how you look at things like fs.readFile() or setTimeout() 💡 👉 Read the full blog here: https://lnkd.in/g-AbBCiy I’d really appreciate your thoughts, feedback, or any experiences you’ve had while working with event propagation 😊 Hitesh Choudhary | Piyush Garg | Akash Kadlag #JavaScript #WebDevelopment #Blog #NodeJs #Cohort2026 #LearnInPublic #libuv #v8

🚀 Understanding Node.js Internals: Event Loop & Thread Pool This week, I took a deeper dive into how Node.js actually works behind the scenes — and it completely changed how I think about asynchronous code. 🔹 JavaScript in Node.js runs on a single thread 🔹 Yet it handles multiple tasks efficiently using the Event Loop 🔹 Heavy operations are offloaded to the Thread Pool (via libuv) Some key takeaways: Event Loop manages execution in phases (Timers, I/O, setImmediate, etc.) setTimeout(0) is not truly immediate setImmediate() behaves differently inside vs outside I/O process.nextTick() runs before the event loop even starts Understanding these concepts makes async behavior much more predictable and helps write better backend code. Would love to hear your thoughts or corrections 🙌!

🚀 Just published a new React package: table-components-react A lightweight and customizable table component built for modern React applications. Designed to simplify data rendering while keeping flexibility for real-world use cases. ✨ Highlights: • Easy to integrate • Customizable columns & data • Clean and reusable components • Developer-friendly API Check it out on npm: https://lnkd.in/dcvj9X-V Feedback and contributions are welcome! #ReactJS #npm #opensource #frontend #javascript

⚛️ React Devs — Why Too Many Custom Hooks Can Hurt Your Codebase Hey React family 👋 Custom hooks are powerful… But let’s be honest: 👉 Some teams create hooks for EVERYTHING. 💥 Result: Hard to trace logic Nested abstractions Debugging confusion Reusability that nobody uses 💡 What I learned: ✔ Create hooks for repeated logic ✔ Keep hooks focused ✔ Avoid “clever” abstractions ⚡ Senior insight: “Abstraction should remove complexity… not hide it.” 👉 Sometimes plain code is better than fancy hooks. How many custom hooks are too many? #reactjs #customhooks #frontendarchitecture #reactdeveloper #javascriptdeveloper #nextjs #softwareengineering #webdevelopment #cleanarchitecture #frontenddev

Quick breakdown for anyone working with modern JavaScript stacks. Here’s how I structure a clean Vue + Vite frontend communicating with a Node.js + Express API layer. The backend runs as an independent service, exposes clear JSON endpoints, and keeps the architecture modular and scalable exactly the kind of setup teams rely on when building real‑world applications. Sharing this to help others understand the workflow and to highlight the engineering practices I bring to full‑stack environments. #NodeJS #ExpressJS #VueJS #Vite #FullStack #SoftwareEngineering #WebArchitecture
