Learned to create a simple HTTP server with Node.js

🚀 Episode 02: JavaScript on the Server! 🧠 Today, I explored how JavaScript—once a purely client-side language—made its way to the server-side with the help of Node.js. 💻 Here are some key takeaways from this episode: 🔹 A server is basically a remote computer that provides resources or services over a network. 🔹 IP Address uniquely identifies every device on the internet. 🔹 V8 Engine, written in C++, powers JavaScript by compiling it into machine code, making it super fast! ⚡ 🔹 Node.js is a C++ application that embeds the V8 engine, enabling JavaScript to run outside the browser. 🔹 Node.js follows ECMAScript standards, but also extends JavaScript with additional capabilities like APIs, database connections, and server operations — making it a full JS runtime environment. Ever wondered how your JavaScript code “comes to life”? 🤔 The V8 engine translates your high-level JS code into low-level machine instructions — the actual language your computer understands. That’s how your code becomes action! 🧩 #JavaScript #NodeJS #WebDevelopment #LearningJourney #V8Engine #ServerSideJS #MERNStack #Coding

When your project starts acting up, don’t panic. Sometimes the fix is as simple as deleting your node_modules folder and running a clean npm install to clear out old data. 🧹 While teaching this live, Malcolm also shared his next build idea: an API project where users can enter a zip code and instantly get data like country, region, and coordinates. 🌍 That’s how you grow as a developer. Solve problems in the moment, then plan what to build next. #CodingTips #WebDevelopment #JavaScript #APIDevelopment #ReactJS #LearnToCode #TechEstateEmpire

I just published checkmyenv — a tiny Node.js CLI that keeps your environment variables in sync. What it does: Scans your codebase for process.env.* usages Compares against your .env and highlights missing/unused keys Generates/updates .env with interactive prompts Syncs with .env.example Works via npx or global install Get started: npx @eminemah/checkmyenv DB_URL API_KEY PORT SECRET_KEY checkmyenv check checkmyenv generate checkmyenv sync Repo: https://lnkd.in/dexahCGs NPM: https://lnkd.in/d6uMqXxv If you try it, I’d love your feedback and PRs! #nodejs #javascript #developerexperience #dotenv #cli #opensource

Why JavaScript Hooks Are a Game-Changer for Modular Code Developers: you’ve likely encountered a situation where you need to extend behavior in your application without modifying the core logic. That’s where hooks come in.

🚀 Just launched VS Code Extension! After often forgetting to remove console.log and debugger statements before pushing code 😅, I decided to build a simple tool to fix that. Introducing 🧹 Remove Log and Debugger — a lightweight VS Code extension that automatically cleans up your code before deployment. ✨ Key Features: Instantly removes all console.* and debugger statements. Supports multiple languages — .js, .ts, .vue, .py, .java, .go, .php, and more. One-click cleanup or use the command palette. Optional watch mode to remove logs as you edit. Built with ⚡ esbuild for fast performance. Perfect for keeping your codebase clean before committing to development or production. You can check it out here: https://lnkd.in/g9f7gi55 Would love your feedback or suggestions for improvements! 🙌 #vscode #developer #javascript #opensource #typescript #productivity #coding

 Stumbling on the TypeScript TS2632 error? If you’ve ever tried to reassign an imported variable in TypeScript and got TS2632, here’s the deal: ES module imports are live, read-only bindings. that means the module that exports a value can change it, but modules that import it cannot reassign the imported name. you can change the contents of an imported object or array (mutate it), but you can’t replace the reference from the importer side. common, practical fixes: - export functions from the module that own the state (recommended). - use a small store/singleton or class that exposes methods to update state - for real apps, put data in a DB and use a proper data layer. If you’re getting this error in tests (trying to overwrite an imported function), consider re-exporting an object or using your module’s API so you can mock/replace it safely.

In Node.js, you can use C++ code to get higher performance. As Node.js is built up on top of C++, so you can leverage add-on to execute the c++ code. Recently, Inexplored it indepth for a usecase, where we needed nano or sub nano second latency on search across thousands of enteries. But apart from that, it gives you ability to directly work at low levels and use native APIs and drivers. To use C++ module, you can use N API or node-gyp. Have you tried it? #nodejs #javascript #backend #c

Backend renamed profile to userProfile last Tuesday. TypeScript didn't warn you because of `any`. User clicked Settings. White screen. Slack exploded. This is the cost of `any`. Silent failures. Runtime surprises. Bugs TypeScript was designed to catch. Read my blog below in the comment 👇🏽 #TypeScript #JavaScript #WebDev #SoftwareEngineering #DeveloperLife

Today I learned about Session in JavaScript! Many beginners think JavaScript doesn’t support sessions, but actually we can manage session-like data easily using sessionStorage. 👉 It helps us store data temporarily — only until the browser or tab is open 🧠 In short: Data lives only for the current browser tab. Perfect for login status or temporary info. Deletes automatically when tab closes. Next, I’ll try the same concept with localStorage (which stores data even after browser close)! #JavaScript #WebDevelopment #Learning #Frontend #CodingJourney #DeveloperLife
