React Event Pooling and event.persist()

🚀 MemoryRouter for Testing and Non-Browser Environments (React Development) MemoryRouter keeps the history of your routes in memory. It's useful for testing React Router components and for running React applications in non-browser environments like React Native. Because it doesn't interact with the browser's history API, it provides a clean and predictable routing environment for testing and other scenarios where a browser context is not available.

Can a framework have its own framework? Because must people call React a framework and Next.js a React framework and my brain is tired 😭 Let me settle this once and for all. React is a library. Not a framework. It gives you tools to build UI. That's it. You decide everything else. Next.js is the framework. Built on top of React. It gives you structure. Routing. Server side rendering. File based pages. Everything React doesn't give you out of the box. Think of it this way React is the engine. Next.js is the car. You can have an engine without a car. But the car needs the engine to move. Now the real question Which one are you more comfortable with and why? 👇🏾 Personally I am more comfortable with Next.js because i like structure. React alone gives me too much freedom and i end up scattered 🥲🥲 Drop your answer below. Let's argue. 👇🏾 #React #NextJS #Frontend #WebDevelopment #WomenInTech #AfricanInTech

🚀 I improved my Next.js app performance without adding any new library… Most developers think performance = install more packages. I used to think the same. But recently, while working on a production project, I focused on fixing fundamentals instead of adding complexity 👇 ✅ Reduced unnecessary re-renders ✅ Optimized API calls (no duplicate fetching) ✅ Used proper dynamic imports in Next.js ✅ Cleaned up unused components & heavy logic 📉 Result? - Faster page load - Better Lighthouse score - Smoother user experience 💡 Biggest lesson: Performance is not about tools — it's about understanding your code deeply. Sometimes, the best optimization is removing things, not adding. Curious — what’s one performance mistake you’ve seen developers make often? #reactjs #nextjs #webdevelopment #frontend #performance #javascript

𝗠𝗼𝘀𝘁 𝗥𝗲𝗮𝗰𝘁 𝗱𝗲𝘃𝗲𝗹𝗼𝗽𝗲𝗿𝘀 𝗮𝗿𝗲 𝗹𝘆𝗶𝗻𝗴 𝘁𝗼 𝘁𝗵𝗲𝗺𝘀𝗲𝗹𝘃𝗲𝘀. “I know hooks.” No—you don’t. Because if you did: your components wouldn’t re-render like crazy useEffect wouldn’t feel like black magic you wouldn’t be “optimizing” things that were never slow I’ve seen this too many times: Dev adds: useMemo useCallback React.memo App still slow. Now debugging is harder. Nothing improved. Because the problem was never 𝗽𝗲𝗿𝗳𝗼𝗿𝗺𝗮𝗻𝗰𝗲. It was 𝘁𝗵𝗶𝗻𝗸𝗶𝗻𝗴. React isn’t confusing. You’re just trying to control something that’s built to be 𝗱𝗲𝗰𝗹𝗮𝗿𝗮𝘁𝗶𝘃𝗲. And React always wins that fight. Fix your 𝗺𝗲𝗻𝘁𝗮𝗹 𝗺𝗼𝗱𝗲𝗹 → everything clicks.

Stop building for 1 million users when you do not even have ten. Your over-engineered tech stack is the silent killer of your productivity. I spent 4 weeks setting up a complex Next.js monorepo for a product with zero users. I thought I was being a visionary, but I was just being expensive. I realized this when looking at the rising cost of living and petrol prices. Every hour spent on unnecessary complexity is an hour of wasted energy and money. The lessons I learned the hard way: - Your tech stack should solve user problems, not fulfill architectural fantasies. - Using every new React feature just because it is trending is a recipe for maintenance hell. - A simple, boring app that ships today is worth more than a perfect one that never launches. Seniority is not about how many libraries you can cram into a package.json. It is about knowing exactly what not to build to keep the project lean. What was the most over-engineered feature you ever built that ended up being completely useless? #javascript #reactjs #nextjs #webdevelopment #softwareengineering

Are you mutating state directly in React? 🛑 If you are using methods like ".push()" on your state arrays, you might be causing hidden UI bugs and skipped re-renders. React relies on immutability to track changes and keep your app running smoothly. Swipe through to see the wrong way, the right way, and exactly why immutability matters in React! 👇 What is your preferred way to handle complex state objects? Let me know in the comments! #ReactJS #WebDevelopment #Frontend #CodingTips #webDev #javascript #frontendInterview

I improved performance in my React app today 🚀 The problem: Slow loading and unnecessary re-renders. What I changed: • Implemented lazy loading (React.lazy) • Applied code splitting • Optimized API calls • Reduced unnecessary state updates Result: ⚡ Faster load time ⚡ Smoother user experience Lesson: Performance is not a feature. It’s a responsibility. What’s one performance trick you always use? #reactjs #performance #webdevelopment #javascript #frontenddeveloper

Completely agree. In the ever‑changing frontend world, trying to learn everything at once is the fastest route to burnout. Better 15 minutes of practice every day than 5 hours on the weekend. Thanks for the reminder

🚀 TypeScript's `Partial` Type with React Props The `Partial` type in TypeScript can be useful when dealing with optional props in React components. Applying `Partial` to a props interface makes all properties optional, which can simplify component usage. However, it's important to handle the possibility of missing props within the component logic. Using `Partial` can make components more flexible, but it also requires careful consideration of potential undefined values.

Is React still enough in 2026? Or has Next.js become the default for modern web apps? There’s a lot of noise around this topic, so we took a step back and looked at it from a practical, real-world perspective. Here’s the short version: ⚛️ React (with Vite) Still a strong choice when you want full control over your architecture. Great for internal tools, dashboards, and apps where you already have a backend. 🚀 Next.js Builds on React with built-in features like routing, server rendering, and API handling. Useful for public-facing apps, especially when SEO and performance are important. The truth is — there’s no one-size-fits-all answer. It depends on what you’re building and the tradeoffs you’re willing to make. We break this down in detail (without the hype) in this video: https://lnkd.in/dKdCFRcB What are you using right now?
