Lazy Loading for Faster App Performance

You’re probably wasting precious time on unnecessary renders. What if I told you that a few tweaks to your React hooks could drastically speed up your app? 🚀 Imagine this: You’re in the final stages of deploying a major feature. Users are excited, but you notice the load times are dragging. Frustration sets in. You know your code is solid, but there’s something holding it back. Then it clicks. You dive into optimizing your useEffect and useMemo hooks, tuning them to only trigger when absolutely necessary. 🎯 Suddenly, those sluggish load times vanish, and you’ve freed up 30%! The team is ecstatic, and your users get the seamless experience they deserve. The best part? This isn't just about speed; it's about creating an environment where your team can thrive, focusing on what truly matters—delivering value to your users! 💪✨ So, are you ready to optimize? What’s the last thing you did to boost your app’s performance? Share your experiences below! 🗣️👇 #ReactJS #WebDevelopment #Productivity

Configuring DeadBro just got a lot easier. You now only need to add your API key — everything else can be controlled directly from the UI. Toggle features on/off, adjust sampling, enable memory or SQL tracking… all without redeploying your app. The gem automatically picks up changes on the next request. Less config. More control. If you're running Rails apps and care about performance, this is a big step forward. https://www.deadbro.com

𝗦𝗰𝗮𝗹𝗮𝗯𝗹𝗲 𝗥𝗲𝗮𝗰𝘁 𝗔𝗽𝗽𝗹𝗶𝗰𝗮𝘁𝗶𝗼𝗻𝘀 You start with a clean React app. Over time, it gets messy. Files are all over the place. Logic is hard to track. Reusability becomes a problem. I faced this issue. The solution was simple: organize by feature, not file type. Group files by what they do in your app. Here's how: - src/ • assets/ • components/ • features/ • auth/ • dashboard/ • profile/ • hooks/ • services/ • store/ • utils/ This structure keeps everything related to a feature in one place. Each feature is self-contained. For example, features/auth/ has its own components, api, and hooks. The index.ts file controls what the rest of your app can access. You have two types of components: - Shared Components - Feature Components This separation keeps your shared components clean. If your app is growing fast, has multiple features, and is hard to navigate, this structure will help. Good structure is not important on day one. But it matters a lot a few weeks in. Organize by feature early, and you will thank yourself later. Source: https://lnkd.in/g3jbF-6E

Your app is slow… and you don’t even know it. Users won’t tell you your app is slow. They’ll just stop using it. This week, I reviewed a Flutter app that looked perfect. But: • Frame drops on scroll • Unoptimized API calls • Heavy widget rebuilds Result? Low retention. The painful truth: Performance issues are silent killers. As The Extra Mile Guy, performance is not optional. It’s engineered.

A fast UI doesn’t mean a fast application. If your APIs take 2 seconds… your app is already slow. Users don’t see your code. They feel the delay. 🚀 Performance starts where the request begins — not where it ends.

𝗥𝗲𝗮𝗰𝘁 𝗖𝗼𝗺𝗽𝗼𝗻𝗲𝗻𝘁-𝗕𝗮𝘀𝗲𝗱 𝗔𝗿𝗰𝗵𝗶𝘁𝗲𝗰𝘁𝘂𝗿𝗲 Build your user interface with small, independent parts. These parts are called components. Examples include: - Buttons - Navbars - Forms Each component manages its own logic and style. This modular style makes your code reusable. You scale your app faster. You fix one part without breaking others. The virtual DOM increases speed. It updates only the parts you change. Source: https://lnkd.in/g8ryt35d

"A fast app feels magical… a slow app gets closed." 🚀 Here are some simple Performance Optimization Tips every developer should know 👇 🔹 Minimize unnecessary re-renders 👉 Use memoization (React) 👉 Avoid extra state updates 🔹 Lazy load components 👉 Load only what’s needed 👉 Improves initial load time ⚡ 🔹 Optimize images 👉 Compress images 🖼️ 👉 Use modern formats (WebP) 🔹 Use caching wisely 👉 Store frequently used data 👉 Reduce API calls 🔹 Reduce API calls 👉 Batch requests 👉 Avoid duplicate calls 🔹 Use CDN 👉 Serve assets from nearest location 🌍 👉 Faster load time 🚀 Pro Tip: Measure performance first → then optimize (don’t guess). 💬 What’s one trick you’ve used to improve app performance? #webdevelopment #performance #mern #javascript #developers

In Next.js App Router, what is the purpose of the loading.tsx file placed inside a route folder (e.g., app/dashboard/loading.tsx), and how does it work? loading.tsx is just Next.js automatically wrapping your page in a <Suspense> boundary with your loading UI as the fallback. So when you create loading.tsx, Next.js does this for you automatically: <Suspense fallback={<Loading />}> // ← your loading.tsx <Page /> // ← your page.tsx </Suspense> You don't have to write the Suspense wrapper yourself — Next.js handles it. 😎 #nextjs

Faced a real issue with React Context API in React Native While working on a production app, I noticed unnecessary re-renders across multiple components due to Context API updates. Even small state changes were triggering full component tree updates. After debugging, I realized: Context API is not optimized for frequent or complex state updates Switched part of the app to Zustand and saw immediate improvements: 1.Reduced re-renders 2.Cleaner code 3.Better performance Lesson learned: Context API is great for small use cases, but for scalable apps, lightweight state managers like Zustand make a big difference. #ReactNative #Zustand #ContextAPI #Performance #MobileDevelopment

Not everything needs to loads. At least not immediately. Have you ever had a long scrolling product page with a heavy recommendation component at the bottom? Most users will never scroll there, yet you are still loading this part when navigating to this page. @defer fixes this declaratively. The component only loads when it enters the viewport, Angular handles the code splitting automatically. From on viewport to on interaction or idle, there's a trigger for every use case. Although this doesn't look as exciting as introduction of Signals or even default zoneless app, it is still a powerful tool and you should definitely give more love to this feature.
