Guardian Care 24/7 Web App for Emergency Care Booking

I stopped writing messy React code… and my projects became 10x easier to maintain. Here’s what changed 👇 Most developers focus on “making it work.” But clean code is what makes it scalable. One simple habit I adopted: 👉 Extract logic into reusable hooks Instead of this 👇 useEffect(() => { fetch("/api/users") .then(res => res.json()) .then(data => setUsers(data)) .catch(err => console.error(err)); }, []); I now do this 👇 // useFetch.js import { useState, useEffect } from "react"; export function useFetch(url) { const [data, setData] = useState(null); useEffect(() => { fetch(url) .then(res => res.json()) .then(setData) .catch(console.error); }, [url]); return data; } Then use it anywhere 👇 const users = useFetch("/api/users"); 💡 Why this matters: Cleaner components Reusable logic Easier debugging Better scalability Small improvements like this separate average developers from great ones.

Just shared a new article on Medium about React Custom Hooks! 🚀 As React developers, we often struggle with bloated components. Custom Hooks are a game-changer for extracting reusable logic and keeping our codebase DRY (Don't Repeat Yourself). In this article, I cover: ✅ What Custom Hooks are ✅ Building a reusable useFetch hook ✅ Best practices for clean code Check it out here: https://lnkd.in/g2Pp46As #ReactJS #WebDevelopment #JavaScript #Programming #Frontend #CodingTips

Here’s a quick mental model 👇 𝗖𝗼𝗺𝗺𝗼𝗻𝗝𝗦 Used in classic Node.js backends const lib = require('lib'); Simple and synchronous. Still widely used, but gradually being replaced. 𝗘𝗦 𝗠𝗼𝗱𝘂𝗹𝗲𝘀 (𝗘𝗦𝟮𝟬𝟭𝟱+) Modern standard for browsers and Node.js import lib from 'lib'; Tree-shakable, static, and the future of JavaScript. 𝗔𝗠𝗗 Designed for browsers before native modules existed (RequireJS era) define(['dep'], function(dep) { ... }); Now mostly legacy. SystemJS Dynamic module loader System.register([...], function(...) { ... }); Used in specific cases like plugin systems or legacy apps. 𝗨𝗠𝗗 "Write once, run anywhere" format Works in both browser and Node.js if (typeof define === 'function') { ... } Common in older libraries that needed maximum compatibility. 💡 Key takeaway: Use 𝗘𝗦 𝗠𝗼𝗱𝘂𝗹𝗲𝘀 for modern apps Expect 𝗖𝗼𝗺𝗺𝗼𝗻𝗝𝗦 in backend or legacy code Treat 𝗔𝗠𝗗 / 𝗦𝘆𝘀𝘁𝗲𝗺𝗝𝗦 / 𝗨𝗠𝗗 as historical or niche Understanding these formats makes debugging build issues much easier. #JavaScript #Frontend #WebDevelopment #NodeJS #SoftwareEngineering #DevTips #Programming

If you’re writing 5 files just to toggle a boolean... 🛑 You’re not scaling. You’re over-engineering. For a long time, I used Redux for almost everything in React. And honestly? It felt powerful... but also unnecessarily complex for 90% of my use cases. Recently, I switched to Zustand — and the difference is 🔥 Why Zustand just makes sense: ✅ Zero Boilerplate No Providers. No massive folder structures. Just create and use. ✅ Hook-Based If you know useState, you already understand Zustand. It feels like native React. ✅ Performance First It handles selective re-renders out of the box. Only the components that need the data will update. 💻 The "Store" is this simple: JavaScript import { create } from 'zustand' const useStore = create((set) => ({ count: 0, inc: () => set((state) => ({ count: state.count + 1 })), })) Use it anywhere: JavaScript function Counter() { const { count, inc } = useStore() return <button onClick={inc}>{count}</button> } ⚡ 𝗣𝗥𝗢 𝗠𝗢𝗩𝗘 (Most developers miss this): Use selectors to grab only what you need: const count = useStore((state) => state.count) This keeps your app lightning-fast even as your state grows massive. 📈 Since switching, my code is: → Simpler → Cleaner → Easier to maintain 🟣 Team Redux (The tried and true) 🐻 Team Zustand (The minimalist) #ReactJS #Zustand #JavaScript #WebDevelopment #Frontend #CodingTips #SoftwareEngineering

🚀 Day 23/30 – React Best Practices Most React developers don’t struggle with syntax… 👉 They struggle with writing maintainable code 👀 Today I focused on what actually makes code production-ready ⚡ 💡 What I realized: Clean code is not about making things “look good” 👉 It’s about making code easy to understand, scale, and debug 💻 Practices I’m following: ✅ Keep components small & focused → One component = one responsibility ✅ Use meaningful names → Code should explain itself (no comments needed) ✅ Avoid prop drilling → Use Context when data goes deep ✅ Reuse logic with custom hooks → Don’t repeat yourself ✅ Separate business logic from UI → Components should focus on rendering ✅ Handle loading & errors properly → Real apps are not always “happy path” 🔥 Reality Check: 👉 Messy code works… until it doesn’t 👉 Clean code scales… messy code breaks ⚡ Advanced Insight: Senior developers don’t write “clever” code 👉 They write predictable, readable code 🔥 Key Takeaway: Anyone can write code that runs 👉 Not everyone writes code that lasts Be honest 👇 Would another developer understand your code in 30 seconds? 👀 #React #CleanCode #FrontendDevelopment #JavaScript #BestPractices

React solves a lot of real problems, but as developers I think we are using it as a hammer for everything – overcomplicating maintenance and expanding our attack surface unnecessarily. Now with AI-assisted software development this is already getting out of hand, as most of the models default to React for everything. There's a lot of magic, ecosystem instability and the steep learning curve is really eating into profits. Just track your development time for a quarter and you'll notice how much of it is trying to stay on top of the so-called modern JS. In late 2024 we rewrote our custom admin framework from React to vanilla Node.js with no build step and minimal dependencies and immediately we benefited from the faster deploys, fewer security vectors, simpler debugging, and a system our team understands and control end-to-end. Investing an afternoon to create a Claude skill for it was a no brainer to help bring LLMs onboard, so we are not missing much from leaving the “defaults”. Today the web is better than ever and standard web technology, deliberately applied always wins! So it's not a surprise that this post resonated with me: https://lnkd.in/eCKAPvP5

Node.js Core Concepts 🚀 Mastering the fundamentals is what separates good backend developers from great ones. Here are the 7 Node.js core concepts every developer should know: 1️⃣ Event Loop The heart of Node.js. One thread. Thousands of concurrent operations. Understanding phases (Timers → I/O → Poll → Check → Close) is non-negotiable. 2️⃣ Non-Blocking I/O Stop blocking your thread with readFileSync. Async callbacks, promises, and streams keep your app responsive under load. 3️⃣ Callbacks → Promises → Async/Await We've come a long way from "Callback Hell". Async/Await gives you clean, readable, maintainable code. Use it. 4️⃣ Streams Don't load 2GB files into memory. Process data in chunks with Readable, Writable, Duplex, and Transform streams. Your RAM will thank you. 5️⃣ Module System CommonJS vs ES Modules — know the difference. ES Modules are the future. Start thinking in import/export. 6️⃣ Error Handling Unhandled errors crash apps. Use try/catch, handle rejected promises, and always set up process.on('uncaughtException') as your last line of defense. 7️⃣ Scalability — Cluster & Worker Threads I/O-heavy? → Cluster mode. CPU-heavy? → Worker Threads. Multi-core systems exist for a reason — use them. 💡 The Big Picture: Node.js isn't just JavaScript on the server. It's a mindset — async-first, event-driven, built to scale. Master these concepts, and frameworks like Express, NestJS, and Next.js will feel effortless. What concept took you the longest to truly "get"? For me it was the Event Loop 👇 #NodeJS #Backend #WebDevelopment #JavaScript #SoftwareEngineering #Programming

🚀 Strengthening my React fundamentals! Here are 10 core concepts every React developer should know (and actually understand 👇) 1️⃣ React is a declarative, component-based library for building UIs 2️⃣ UI updates when state or props change 3️⃣ State = mutable data inside a component 4️⃣ Props = read-only data from parent to child 5️⃣ "useEffect" handles side effects (API calls, timers) 6️⃣ Virtual DOM improves performance 7️⃣ Keys help React track list updates efficiently 8️⃣ Controlled components = form inputs managed by state 9️⃣ Lifting state up helps share data between components 🔟 Custom hooks allow reusable logic 💡 Learning React is not about memorizing—it’s about understanding how UI reacts to data. #ReactJS #FrontendDevelopment #WebDevelopment #LearningInPublic #JavaScript
