Most React devs still handle form submissions with a `loading` boolean. It works. But it creates that awkward pause where everything freezes while waiting for the server to respond. React 19 shipped `useOptimistic` to fix exactly this. The idea is simple: → User submits → UI updates instantly → Server processes in the background → Error? It auto-reverts to the previous state Here's the actual code: const [optimisticName, setOptimistic] = useOptimistic( serverName, (current, newName) => newName ); async function handleSubmit(formData: FormData) { const name = formData.get('name') as string; setOptimistic(name); // instant UI update await updateName(name); // real server call } No separate loading state. No flickering button. The UI responds immediately, and React handles the rollback automatically if the server call fails. Works especially well with Next.js Server Actions - the combo feels really natural. I built a profile edit flow with this recently. Users don't even realize they're waiting for the server. Are you using `useOptimistic` yet, or still managing loading states the old-school way? #ReactJS #NextJS #TypeScript #Frontend #WebDev

🚀 React.js! Getting more comfortable with React now! Today I explored one of the most important hooks — useEffect. 💡 What I learned today: • useEffect for handling side effects • Fetching data from APIs • Component lifecycle basics in React • Clean and efficient code structure 👨💻 Tried a simple example: import React, { useState, useEffect } from "react"; function Users() { const [users, setUsers] = useState([]); useEffect(() => { fetch("https://lnkd.in/g7MrTyES") .then((res) => res.json()) .then((data) => setUsers(data)); }, []); return ( <div> <h2>User List</h2> {users.map((user) => ( <p key={user.id}>{user.name}</p> ))} </div> ); } export default Users; This helped me understand how React handles data fetching and updates the UI dynamically ⚡ Slowly building confidence and consistency 💪 If you have any tips, resources, or beginner project ideas, feel free to share 🙌 #ReactJS #JavaScript #FrontendDevelopment #WebDevelopment #Coding #Programming #Developer #SoftwareDeveloper #LearningJourney #Day3 #100DaysOfCode #CodeNewbie #Tech #UI #WebDev #ReactHooks #useEffect #APIs #Frontend #CodingLife #Developers #TechCommunity #LearnInPublic

Started exploring NestJS (Node.js Framework)🐈⬛ recently, and honestly, it changed the way I look at backend development. Coming from building APIs in a more unstructured way, NestJS felt like stepping into a system that actually guides you instead of leaving you to figure everything out on your own. What stood out immediately: -- A clean, predefined folder structure that forces you to think in modules -- Built-in error handling mechanisms -- Formatting and linting already configured -- A consistent architectural pattern from day one All of this comes out of the box, which means I don’t have to waste time setting up the basics again and again. Instead, I can focus directly on what actually matters — the business logic. Another interesting thing I learned is that under the hood, NestJS uses Express.js. So while it feels like a high-level framework, it’s still powered by a battle-tested HTTP server. This combination of structure + flexibility is what makes it powerful. It’s not just a framework, it’s almost like a backend design philosophy. Still early in the journey, but it definitely opened up a new way of thinking about building scalable backend systems. #NestJS #BackendDevelopment #NodeJS #WebDevelopment #SoftwareEngineering #LearningInPublic #Developers #TechJourney

🚀 Node.js Performance Tip Most Developers Still Ignore If your API feels slow, there’s a high chance you’re making this common mistake 👇 ❌ Sequential API Calls Running async operations one by one increases total response time unnecessarily. const user = await getUser(); const orders = await getOrders(); const payments = await getPayments(); ⏱️ If each call takes 100ms → Total = 300ms ⸻ ✅ Optimized Approach: Promise.all() const [user, orders, payments] = await Promise.all([ getUser(), getOrders(), getPayments() ]); ⚡ Now all requests run in parallel ⏱️ Total time ≈ 100ms ⸻ 💡 Key Rule: If your API calls are independent, NEVER run them sequentially. ⚠️ Use Promise.all() only when: ✔️ No dependency between requests ✔️ You can handle failures properly ⸻ 🔥 Why this matters: • Faster APIs = Better user experience • Better performance = Higher scalability • Small optimization = Big impact ⸻ 💬 Want more backend performance tips like this?

"Great insight! It’s impressive how a small change like using Promise.all() can significantly improve performance. Definitely a must-know for every backend developer. 🚀"

One interesting thing about working as a full stack developer… You stop blaming just one side 😄 Earlier: If UI breaks → “frontend issue” If data is wrong → “backend issue” Now: You realize both are connected. Sometimes the problem is: → API response structure → State handling on frontend → Missing edge cases → Or just one small logic mistake somewhere in between Full stack development teaches you one thing clearly: 👉 The bug doesn’t belong to frontend or backend 👉 It belongs to the flow And fixing that flow is where the real learning happens. Still figuring it out, one bug at a time 👨💻 #FullStackDeveloper #ReactJS #NodeJS #JavaScript #WebDevelopment #BuildInPublic

Why I’m choosing "Boring" Tech over the latest JS Frameworks: I know, I know. We’re supposed to love the 15th new React framework released this month. We’re told that if we aren’t using Server Actions, Edge Computing, and 4 layers of abstraction, we’re "falling behind." But for my latest web build, I went back to the basics (Vite + React SPA), and here is why: The "Localhost" Speed (DX): Configuring complex SSR (Server-Side Rendering) rules feels like fighting the framework. With a clean Vite setup, the dev server is up in milliseconds. No "Hydration Errors," no mysterious server-only crashes. Just pure, fast coding. Deployment Shouldn't be a Puzzle: I don't want to be locked into a specific hosting provider just to get "optimal performance." A client-side app is just a folder of static files. I can host it on a CDN for pennies, and it scales to millions of users without me touching a single server config. State Management without the Headache: In the SSR world, sharing state between the server and the client is a constant battle. In a dedicated SPA, the "Source of Truth" is clear. It’s predictable, it’s testable, and it’s fast. 𝐓𝐡𝐞 𝐕𝐞𝐫𝐝𝐢𝐜𝐭? The modern web stack is becoming an Over-Engineered Monster. We’re solving problems that 90% of apps don't even have. Sometimes, a simple, fast car is better than a space shuttle when you're just trying to drive across town. Is the "Full-Stack Framework" hype-train slowing down? Or am I just getting old?
