Automate Backend Setup with Bend for NodeJS

I just published a new blog about how Node.js actually works under the hood. When we use Node.js it feels like JavaScript can do everything - read files, make network requests, talk to the OS. But JavaScript alone can't do those things. Inside Node.js, a few key components work together: V8 → runs JavaScript C++ bindings → connect JS to native code libuv → handles async operations and the event loop Understanding this made Node.js architecture much clearer for me, so I wrote a simple breakdown.

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

I simplified my system by deleting the custom "Crew" implementation in my latest refactor. I was mid-build on a custom system when I realized Better-Auth natively supports a "Members" schema. Even though I was halfway through, the trade-off made sense. Switching to the native implementation will save me a maintenance headache in the long run. Less custom code means fewer bugs to track. Wins from the pivot: • Simplified state to eliminate redundant renders. • Used Zod to harden permissions at the boundary. My Takeaway: Sometimes we get attached to one way of thinking because we've put hours into a solution. However, there is strength in knowing when it's the right time to pivot. #BuildInPublic #SoftwareEngineering #JavaScript #NextJS

🚀 Day 19 — Understanding Build & Deployment Today I worked on solving a real-world deployment issue and understood an important concept: Build and Dist folder. 🧠 What I learned today: • Faced issue where frontend and backend were running on different ports • Learned how to combine both for deployment 👉 Ran "npm run build" This process converts React code into optimized HTML, CSS, and JavaScript 👉 A dist folder is generated This folder contains the final production-ready files that browser can understand • Moved these files into backend’s public folder • Now backend can serve both frontend + backend from one server 💡 In simple terms: Build = converting code into production-ready format Dist folder = final website files This helped me understand how real-world applications are actually deployed 🚀 #FullStackDevelopment #Deployment #ReactJS #NodeJS #ExpressJS #WebDevelopment #BuildInPublic #LearningJourney #Day19

🤯 JavaScript did WHAT here?! const str = "1,2,3" const arr = [1,2,3] console.log(arr == str) // true 😳 console.log(arr === str) // false 🤔 Same data… different results? This is exactly why many developers get confused between == and ===. 👉 How did an array become equal to a string? 👉 Why does strict equality behave differently? 👉 And when should you actually use each? I break this down in a simple way in my latest video 🎥 If you've ever been surprised by JavaScript comparisons, this one's for you. #JavaScript #WebDevelopment #Frontend #CodingTips #LearnToCode

Want to learn more about React hooks? I recently stumbled upon BigFrontEnd.dev and have been really enjoying it. I’ve been spending some time in the React section, which has exercises where you predict what gets printed to the console when using React hooks. It’s been a great way to better understand how state updates work, when React re-renders a component, and how closures can affect values inside hooks. They also have a solid JavaScript section. I started exploring those to get a better feel for what actually gets logged when you combine things like console.log, setTimeout, and Promises. It’s been helpful for reinforcing how JavaScript handles execution order and the event loop. If you’ve been wanting to dig a little deeper into React hooks or brush up on JavaScript behavior under the hood, I highly recommend it Please let me know if there are any other great resources you use as well. #react #reacthooks #state #javascript

𝗧𝗵𝗲 𝗩𝗶𝗿𝘁𝘂𝗮𝗹 𝗗𝗢𝗠 𝗘𝗻𝗴𝗶𝗻𝗲 You use React, but do you know how it works? Let's break it down. The Virtual DOM is not a performance optimization. It's a programming model where you describe what the UI should look like. The framework figures out the minimal set of changes. - You write UI in HTML, but HTML is a string. - JavaScript can't inspect the tree or compute what changed. - What if you described the structure as a plain JavaScript object instead? We'll build a Virtual DOM engine in 100 lines of vanilla JavaScript. Four functions: - h() to create virtual nodes - render() to mount to the DOM - diff() to compare two trees - patch() to apply changes The engine works in two phases:

While working on a full-stack project with Next.js, I sometimes needed to quickly check environment variables without modifying the code. Here’s a simple way to do it directly from the terminal (required 'dotenv' library): Check env value: node -e "require('dotenv').config(); console.log(process.env.DATABASE_URL)" It’s a small tip, but quite useful when you want to check env value. I’ll probably share a few more small things like this from my project along the way. #nextjs #nodejs #dotenv #webdevelopment #softwareengineering #buildinpublic #javascript #devtips #webdevUK

Most devs reach for a state management library too fast. Before you install Redux or Zustand, try this 👇🏾 // Manage related state together, not separately const [form, setForm] = useState({ name: '', email: '', password: '' }) const handleChange = (e) => { setForm(prev => ({ ...prev, [e.target.name]: e.target.value })) } One state object. One handler. Works for 90% of forms. Stop adding dependencies before you need them. Save this 🔖 #ReactJS #JavaScript #WebDevelopment #Fullstack #CodingTips

⚠️ Struggling with messy JavaScript apps or unexpected bugs? Chances are it’s because the foundation, your modules, isn’t fully understood. ES Modules solve this: isolated scope, explicit dependencies, live exports, and predictable execution. They’re not just syntax, they’re the backbone of modern JS. 💡 For a full breakdown of how modules actually work and how to structure clean, maintainable JS applications, check out the deep dive: https://lnkd.in/dFvxYbYB
