Integrating LLMs with Next.js 16 and WebAssembly

Your app isn’t slow… it’s leaking memory. And most developers don’t notice until it’s too late. In large JavaScript applications, memory leaks quietly destroy performance... especially in real-time systems. The scary part? Your app still “works”… until it crashes. So what’s really happening? JavaScript uses automatic garbage collection, but it’s not magic. If references are unintentionally kept alive, memory can’t be freed. Common culprits: → Forgotten event listeners → Closures holding stale data → Detached DOM nodes → Long-lived caches & timers In one real-time project, fixing just a few lingering listeners reduced memory usage by 40% 🚀 The key insight: Memory leaks aren’t bugs you see... they’re problems you feel over time. Build with awareness. Monitor aggressively. Clean up intentionally.

Building a library isn't the most complex thing in the world but it does require creativity Over the past few days, I've been working on a cross-platform UI component library called dazo-ui Many people find it hard to switch from React to React Native, but the switch itself is simpler than it looks you mainly just change your components. And that's where the idea behind dazo came from Why change the components at all when you can use the same ones you use on the web? The project is still in beta with just a few components, but the concept is there here's how I approached building it Before writing a single line, I evaluated three approaches: 1-RN Bridge : Let the bridge handle all the translation between web, android, and ios the most straightforward starting point but it comes with a performance cost on the web especially when rendering many components on a single page. Rare, but it happens 2-Split files : Create two files .native and .web and let the bundlers pick the right one metro picks .native, and Vite or tsup picks .web. Good for performance, but it bloats the mobile package with unused web files, increasing app size 3-Conditions : One file with Platform.OS checks inside the code simple and clean for small libraries but once you start scaling or onboarding contributors you end up with boilerplate code everywhere There's also a fourth path: building your own compiler, which is exactly what Tamagui does. Too complex for a first version, but something I might explore down the road. The docs site is live " https://lnkd.in/dcigg6kq " and yes, it's built with dazo-ui itself ,I'd love to hear your thoughts and if you're interested in contributing let me know

🚀 **Built a Live Character Counter App** Recently, I worked on a small project — a **Live Character Counter App** — to strengthen my JavaScript fundamentals. Through this project, I practiced: * String methods like `trim()` and `replace()` * Array method `filter()` for accurate word counting * Conditional logic * DOM manipulation * Event handling (especially `input` events) The app tracks: ✔ Character count ✔ Word count ✔ Remaining characters ✔ Live input feedback This project helped me understand how to handle edge cases like extra spaces and improve user experience with real-time updates. 💡 Small projects like this build a strong foundation for real-world applications. 🔗Live preview:- https://lnkd.in/gGVaUv9G If you have any suggestions or ideas for improvement, I’d really appreciate your feedback in the comments 🙌 #JavaScript #WebDevelopment #FrontendDevelopment #CodingJourney #100DaysOfCode

🚀 REDUX — Manage State. Simplify Complexity. State management can become messy as applications grow. That’s where Redux helps by providing a predictable and centralized way to manage your app’s state. 💡 What is Redux? Redux is a state management library for JavaScript applications (commonly used with React). Think of it as a single source of truth (store) for your entire app. ⚙️ How Redux Works: 1️⃣ Store → Holds the complete state 2️⃣ Actions → Describe what happened 3️⃣ Reducers → Decide how state changes 4️⃣ Dispatch → Sends actions to update state 📌 Example Flow: User logs in → Action dispatched → Reducer updates state → UI updates automatically 🔥 Why use Redux? ✔️ Predictable state management ✔️ Easier debugging ✔️ Scales for large applications ✔️ Cleaner architecture 💡 Pro Tip: Use Redux Toolkit to reduce boilerplate and speed up development. 💬 I love discussing React, Redux, and frontend best practices.

💡 How would you design a real-time notifications system in a frontend app? Here’s a practical approach I like to follow. I separate communication into two layers: 🔹 REST APIs for CRUD operations 🔹 WebSockets for real-time updates On the frontend, I create a WebSocket service that: • Maintains the connection • Handles reconnection logic • Parses incoming messages To keep things scalable and decoupled, I use a pub/sub (event-based) system. Components subscribe to specific notification types, so updates flow efficiently without tight coupling. For state management, notifications live in a centralized store or data-fetching layer—ensuring consistency across the app. ⚡ Performance matters: • Batch updates when needed • Avoid unnecessary re-renders (memoization) • Limit rendered items (virtualization or pagination) And of course, don’t forget the edge cases: 🔸 Connection loss 🔸 Duplicate messages 🔸 Message ordering Clean architecture + resilience = a smooth real-time experience.

🚀 Started learning Redux Toolkit — and built a simple Budget Tracker! To understand Redux better, I created a small project using React + Redux Toolkit. 💡 What this app does: • Add income and expense transactions • Automatically calculates total income, expense, and balance 🧠 What I learned: • How Redux store and slices work • Using useDispatch and useSelector • Managing global state in React This project helped me understand Redux concepts much more clearly. Planning to improve it further by adding more features soon! Would love your feedback 🙌 #React #Redux #FrontendDevelopment #WebDevelopment #JavaScript #LearningJourney

Your React app is slower than it needs to be. Here's how to fix it. Most devs write React the way they learned it — and never revisit it. The result? Unnecessary re-renders, bloated bundles and lists that freeze on scroll. In this carousel I cover 5 patterns I apply to every React project: → useCallback & useMemo — when to use them (and when not to) → Why state lifting is silently killing your render tree → Code splitting: route-level is the highest ROI change you can make → Virtualisation for long lists — 10,000 rows in under 5ms → The performance checklist, in priority order Save this.
