Fixing UI Flicker with useLayoutEffect in React

🚧 Error Boundary vs try/catch in React — Know the Difference 🚧 One common misconception I often see among frontend developers is assuming that try/catch can handle all errors in a React application. In reality, React Error Boundaries and try/catch solve very different problems, and understanding this distinction is crucial for building stable, production-ready UIs. Let’s break it down simply. If Dashboard crashes during render → ✔ App does NOT break ✔ Fallback UI is shown ✔ Error can be logged (Sentry, LogRocket, etc.) <ErrorBoundary fallback={<p>Something went wrong</p>}>  <Dashboard /> </ErrorBoundary> 💬 If you’ve ever faced a white screen in production, Error Boundaries could have saved you. #ReactJS #FrontendDevelopment #JavaScript #WebDevelopment #ErrorHandling #ReactPatterns

Headline: Are your React apps slowing down as they grow? 🚀 Performance isn't just a "nice-to-have"—it's a core part of the user experience. As React developers, it’s easy to get caught in the trap of unoptimized renders and bloated bundles. I put together this quick guide on the 3 most common React Performance Pitfalls I see in modern web development: 1️⃣ Unoptimized Renders: Every state change shouldn't trigger a full-tree re-render. 2️⃣ Large Bundle Sizes: Stop importing entire libraries when you only need a single function. 3️⃣ Expensive Computations: Keep your render cycle light by offloading heavy logic. The goal isn't just to write code that works, but to build applications that feel instant. What’s your go-to trick for keeping React snappy?

Memory Leaks in JavaScript: The Silent Performance Killer Ever noticed your web app getting slower over time? You might have a memory leak. A memory leak happens when your code holds onto memory it no longer needs. JavaScript's garbage collector can't clean up what's still being referenced. #JavaScript #WebDevelopment #Performance #CleanCode #Frontend #React #vue

⚛️ 𝟓 𝐑𝐞𝐚𝐜𝐭 𝐌𝐢𝐬𝐭𝐚𝐤𝐞𝐬 𝐓𝐡𝐚𝐭 𝐌𝐚𝐤𝐞 𝐘𝐨𝐮𝐫 𝐀𝐩𝐩 𝐒𝐥𝐨𝐰𝐞𝐫 If your React app feels slow, laggy, or unresponsive, Chances are, the issue isn’t React itself, but how it’s being used. Here are 5 common React mistakes that silently hurt performance 👇 🔹 1. Unnecessary Re-renders ❌ Not memoizing components or passing unstable props ✅ Use React.memo, useMemo, and useCallback wisely 🔹 2. Heavy Logic Inside Render ❌ Performing expensive calculations during render ✅ Move logic outside render or memoize results 🔹 3. Large Lists Without Virtualization ❌ Rendering thousands of DOM nodes at once ✅ Use list virtualization techniques 🔹 4. Incorrect useEffect Dependencies ❌ Missing or incorrect dependency arrays are causing extra renders ✅ Always define dependencies carefully 🔹 5. No Code Splitting or Lazy Loading ❌ Loading the entire app upfront ✅ Use React.lazy and dynamic imports 🎯 Why This Matters ✔️ Faster load times ✔️ Smoother UI interactions ✔️ Better user experience ✔️ Higher performance scores 📌 Key Insight: React performance isn’t about tricks — It’s about writing predictable, optimized components. If you’ve faced any of these issues in production, share your experience. 𝐿𝑒𝑡’𝑠 𝑏𝑢𝑖𝑙𝑑 𝑓𝑎𝑠𝑡𝑒𝑟 𝑅𝑒𝑎𝑐𝑡 𝑎𝑝𝑝𝑠 🚀 𝗜 𝗵𝗮𝘃𝗲 𝗽𝗿𝗲𝗽𝗮𝗿𝗲𝗱 𝗖𝗼𝗺𝗽𝗹𝗲𝘁𝗲 𝗜𝗻𝘁𝗲𝗿𝘃𝗶𝗲𝘄 𝗣𝗿𝗲𝗽𝗮𝗿𝗮𝘁𝗶𝗼𝗻 𝗚𝘂𝗶𝗱𝗲 𝗳𝗼𝗿 𝗙𝗿𝗼𝗻𝘁𝗲𝗻𝗱 𝗗𝗲𝘃𝗲𝗹𝗼𝗽𝗲𝗿.

A small frontend choice that can quietly slow down a Next.js app 👀 Icons feel harmless, right? I used to think so too, until I noticed how they can impact performance. Libraries like react-icons are incredibly convenient, but in Next.js, importing them without care can increase client bundle size and affect initial load time, especially in client components. What worked better for me: - Importing icons from specific sub-packages, not the root - Using inline SVGs for commonly used or above-the-fold icons - Choosing lighter, tree-shake-friendly libraries like Heroicons, Lucide, or Radix Icons - Being mindful about icon usage in shared components It’s a good reminder that great performance is built from small, intentional decisions, not just big architectural ones. Frontend details matter. A lot. #NextJS #React #ReactJS #FrontendPerformance #WebDev #FrontendDevelopment #WebOptimization #JavaScript #TypeScript #UIEngineering #SoftwareDevelopment

So you wanna make your React app more dynamic. It all starts with props - they're like messengers between components. Props are inputs that customize a component's behavior or content, and they're properties that communicate data from parent to child. This makes components reusable and dynamic, which is pretty cool. You can pass any valid JS value as a prop, like a string or a function. It's like sending a message - you pass props as attributes and receive them as an argument to the component function. For example, let's say you're building a list of skills - you can use props with dot notation, like this: const Skill = (props) => { return <li>{props.skillName}</li>; }; Or, you can use object destructuring, which is a bit more concise: const Skill = ({ skillName }) => { return <li>{skillName}</li>; }; Either way, props are read-only and immutable - so don't even think about trying to modify them. And, you can pass multiple props to a single component, which is handy. Just remember, props are not optional - you gotta pass them, or your component won't work as expected. So, what are some common mistakes to avoid? Well, for starters, don't try to modify props - it's just not gonna work. And, don't forget to pass props, or you'll get an error. Also, make sure your prop names match - it's easy to get them mixed up. And, don't assume props are optional - they're not.

So you wanna make your React app more dynamic. It's all about passing data between components. Props are like messengers - they help you customize a component's behavior or content by passing data from a parent to a child. They're super useful for making components reusable and dynamic. You can pass pretty much any valid JavaScript value as a prop - think strings, numbers, objects, or even functions. Now, when you're passing props, you do it as attributes, and then receive them as an argument to the component function. It's kinda like a conversation between components. You can use dot notation or object destructuring to access props - it's up to you. For instance, you could have a Skill component that looks like this: const Skill = (props) => { return <li>{props.skillName}</li>; }; Or, you know, you could use object destructuring and make it look like this: const Skill = ({ skillName }) => { return <li>{skillName}</li>; }; Just remember, props are read-only - don't even think about trying to modify them. It's like trying to change a message that's already been sent - it's just not gonna work. So, what are some common mistakes to avoid when working with props? Well, for starters, don't try to modify them. And don't forget to pass them when you need to. Also, make sure your prop names match up - it's easy to get them mixed up. And don't assume props are optional - that's just asking for trouble. Check out this guide for more info: https://lnkd.in/gMrvDa_U #React #JavaScript #WebDevelopment

🚀 The Best Way I Learned to Organize React Projects When I first started building React apps, figuring out the “right” folder structure was always tricky. Over time, I learned a setup that keeps things clean, scalable, and easy to navigate. Here’s the structure I’ve been using: src/ │ ├─ components/ # Reusable UI components ├─ pages/ # Page-level components ├─ hooks/ # Custom hooks ├─ context/ # Context API / global state ├─ services/ # API calls, business logic ├─ utils/ # Utility functions ├─ assets/ # Images, icons, fonts, styles ├─ routes/ # App routes └─ App.jsx ✅ Why it works best for me: Easy to find files Scales well as the project grows Keeps logic, UI, and assets separate This structure has made my development faster and my code easier to maintain. Curious to know—what’s the best folder structure you’ve found for React projects? Let’s share tips! 👇 #ReactJS #WebDevelopment #JavaScript #Frontend #CodingTips
