Boost React App Performance with 10 Essential Tips

A common UX pain point I often notice in Next.js Server Components 👇 When a user clicks a link, Next.js navigates to something like /link/[id]. If that route is a Server Component, it runs the DB queries on the server before sending any HTML back to the browser. During that fetch time, the UI often shows no immediate feedback, which can make the app feel stuck or unresponsive. The fix is surprisingly simple ✨ Just add a loading.tsx file. This is a built-in Next.js convention. For example: app/projects/[id]/loading.tsx The moment navigation starts, Next.js instantly renders this loading UI while the server component fetches data in the background. This small addition makes navigation feel significantly faster and smoother. Sometimes great UX is not about speeding up the backend it’s about making the wait feel seamless. 😊 That’s one of the things I really appreciate about how NextJs handles Server Components so elegantly. #nextjs #react #webdevelopment #frontend #ux #javascript #fullstack #developerexperience

React and OHZI Boilerplate often get compared, but they were built to solve different problems. React shines when your app is a tree of UI states reacting to data: dashboards, CRMs, marketing pages, e-commerce. The functional model and virtual DOM are exactly the right abstraction there. OHZI Boilerplate was built from scratch for a different beast: interactive web experiences where WebGL/WebGPU scenes, view-to-view transitions, and frame-perfect timing are the product itself. It is built on Three.js, with a `ViewManager`, `TransitionManager`, and `SceneManager` that own the render loop and orchestrate enter/exit animations between views. When the deliverable is a 3D experience with cinematic transitions, you want a framework whose first-class concepts are scenes, views, and transitions, not components, props, and reconciliation. Different tools, different jobs. Use the one whose primitives match your problem. #WebGL #ThreeJS #React #InteractiveDesign #FrontendArchitecture

🚀 Built an Image Search App using React! Recently, I worked on a project where users can search and explore images dynamically using an API. 🔧 Tech Stack: React (Hooks: useState, useEffect) Tailwind CSS Pixabay API 💡 Key Learnings: Managing state and data flow in React Fetching and rendering API data dynamically Handling user input and triggering side effects Component-based architecture (reusable components) Conditional rendering for better UX ⚡ Features: Search images in real-time Displays likes, views, and tags Clean and responsive UI 🔍 Challenges I faced: Handling API responses and state updates Managing loading and empty states Structuring components properly Excited to keep building and move towards full-stack development 🚀 #React #WebDevelopment #Frontend #LearningInPublic #100DaysOfCode

𝗔 𝗳𝗲𝘄 𝗱𝗮𝘆𝘀 𝗮𝗴𝗼 𝗜 𝘀𝗵𝗶𝗽𝗽𝗲𝗱 𝗺𝘆 𝗳𝗶𝗿𝘀𝘁 𝗻𝗽𝗺 𝗽𝗮𝗰𝗸𝗮𝗴𝗲. 𝗧𝗼𝗱𝗮𝘆 𝗜 𝘀𝗵𝗶𝗽𝗽𝗲𝗱 𝘃𝟬.𝟮.𝟬. 🚩 Honestly, the gap between those two moments taught me more than I expected. Shipping v0.0.1 felt like the finish line. But once it was out in the world, used in a real app, running on a real device, I immediately started seeing edge cases I hadn't thought about. What does the user see when they're offline and the flag hasn't been cached yet? I was showing a blank white SVG. That's not good UX. What if someone needs a square flag for a profile avatar? The 4:3 default doesn't work for that. And the worst one: I was silently caching the error state. So if a flag fetch failed once, that grey placeholder was stored forever, even after coming back online, the real flag would never load. That one stung a bit to find. v0.2.0 fixes all of it: — `aspectRatio` prop: '4:3', '1:1' — `useFallbackEmoji`: show an emoji gracefully when offline — Network failures no longer get cached permanently — Offline state uses a dashed placeholder instead of a blank white SVG What made me smile while writing this post: 130 downloads across two versions in under a week. No marketing, no promotion, just a package that solves a real problem. This is still early. v1.0.0 is coming soon with one final feature I have in mind. But seeing people actually install something I built from scratch, to solve a problem I personally faced, is a feeling I want to keep chasing. More packages are coming. This is just the start. 📦 https://lnkd.in/e77Hb7ZJ 🔗 https://lnkd.in/emXFcPA9 #ReactNative #OpenSource #npm #MobileDevelopment #JavaScript #TypeScript #BuildingInPublic

Pushing Government Web Applications Forward Introducing Vero! An accessible, modern, open-source React component library inspired by USWDS and built with Radix UI. Building on the strong foundation that was established in the Government design community over the past decade, Vero grew out of a desire to offer teams even more modern, flexible building blocks, without losing sight of the principles that define effective government tech. Tools, patterns, and expectations have changed, and teams today need components and architectures built for the modern web. What Vero brings: 🎨 Modern, clean design inspired by USWDS ♿ Accessibility-first using Radix UI primitives 🎯 Full TypeScript support 🎨 Easily themeable with CSS custom properties 📱 Mobile-first & responsive ⚡ Optimized for performance and bundle size People know when an app works well, even if they're unaware of all of the nuances involved in bringing that great user experience to them. It just feels right! Vero is about enabling that end-user experience, especially for those making frontend architectural decisions in the government space. Not reinventing everything. Just pushing the ball forward. Check out Vero at www.capitaltg.com/labs

I didn’t want another “scroll + cards” portfolio. So I built mine like a tool I actually use every day — an IDE inspired by VS Code File explorer 📂 • Tabs 🗂️ • Command palette ⌘ • Themes 🎨 • Copilot-style panel 🤖 Not for aesthetics — but to rethink how developers *navigate and read* content. It forced me to focus on: ⚡ Layout performance ⌨️ Keyboard-first interactions 🧭 Real navigation state (not just sections on a page) Built with React + Vite, structured like a small product — not a landing page. 🔗 https://mohitkuril.xyz/ If the UI feels familiar, that’s intentional 😉 If you notice anything in the UI/UX or functionality that could be improved, I’d genuinely appreciate your feedback — feel free to reach out and discuss. What would you add to a command palette in your own portfolio? #FrontendDevelopment #ReactJS #WebDevelopment #UIDesign

🔐 Built a Clean & Interactive OTP Input Component using React Recently, I worked on building a fully functional OTP (One-Time Password) input UI with a focus on both user experience and real-world usability. ✨ Key Features: • Auto-focus on next input while typing • Backspace navigation (moves to previous input) • Input validation (only digits allowed) • Clean and responsive UI with modern styling • Ref handling using useRef for DOM control 💡 This is a commonly asked frontend interview question in companies like Microsoft, Google, Atlassian, etc., and a great example of how DSA + DOM manipulation + UX thinking come together in real-world applications. 🧠 What I learned: Managing focus dynamically, handling edge cases (like backspace & paste), and building a smooth user experience using React hooks. 🚀 Live demo & code: 👉 GitHub: https://lnkd.in/ga92Jib9 Would love to hear your feedback and suggestions! #ReactJS #FrontendDevelopment #JavaScript #WebDevelopment #UIUX #Coding #InterviewPreparation #100DaysOfCode

I restarted. Again. This time, I followed one simple rule: Done is better than perfect. Just start. Improve along the way. So I built FocusList — a clean and simple To-Do web app focused on productivity and user experience. ✨ What it does: • Smart task menu to quickly view All, Planned, and Focused tasks with counts • Minimal and distraction-free main workspace • Interactive task panel to edit tasks, add notes or delete tasks. • Customizable background themes for a better feel ⚙️ Tech Stack: • React • JavaScript (ES6) • Tailwind CSS • React Router 🛠️ My process: I didn’t try to build everything at once. I started small — just adding tasks. Then step by step: → Improved UI → Added task interactions (edit, delete, complete) → Built a right-side task panel → Focused on responsiveness and UX → Added theming for personalization And honestly, it’s still not “perfect” — but it’s real, working, and improving. That’s what matters. I’d genuinely love to hear your thoughts or suggestions 😊 #BuildInPublic #ReactJS #FrontendDevelopment #UIUX #LearningInPublic
