React Query useQuery Hook Simplifies Data Fetching and Caching

Happy to announce the release of our new open-source package: next-revalidator-js! 🚀 Next.js on-demand caching is an absolute game-changer for frontend performance, but setting up the webhooks to trigger it from your backend is tedious. It usually requires writing custom API routes, coding manual secret token validations, and dealing with repetitive error handling for every single project. My team got tired of the manual setup and actually did something about it. They built a zero-config, plug-and-play package that handles your Next.js on-demand cache revalidation instantly. Drop it in, pass your secret key, and your frontend is securely synced with your backend in under 60 seconds. Why this is a massive win for your architecture: 1. Server-Side Superpowers: You can now safely set your Next.js cache to 1 year. Your database only gets queried when data actually changes, drastically reducing server load, API costs, and database bottlenecks. 2. The User Experience: The instant your backend updates, the Next.js server cache is purged. The very next time a user loads or navigates to the page, they are served the fresh data at static-site speeds. No waiting for arbitrary cache timers to expire. 3. Zero Boilerplate: Built-in secret verification and native support for Next.js 13 through 16. A massive shoutout to Dish Khant for his incredible effort in building and open-sourcing this. He took a frustrating developer bottleneck and engineered a beautiful solution for the whole community. Brilliant work, Dish! 👏 Check out the before-and-after in the image below, and grab the package on npm to try it in your next project: 🔗 https://lnkd.in/dzQPc4H4 #Nextjs #ReactJS #WebDevelopment #OpenSource #JavaScript #DeveloperExperience #WebDev #Backend

Most Next.js developers are doing caching wrong. Here's what fetch() is actually doing behind the scenes — and how to control it. A thread on Next.js Cache one of the most powerful (and confusing) features in the App Router. THE DEFAULT BEHAVIOUR When you use fetch() in a Server Component, Next.js caches the response forever by default. This is called the Data Cache. // This is cached indefinitely const data = await fetch('https://lnkd.in/d7X_BG-a'); That means on every request, your users get a fast response. served from cache, not a live API call. OPT OUT OF CACHING But what if your data changes every second like a live price feed or breaking news? // No cache — always fresh data const data = await fetch('https://lnkd.in/drnwrKAk', {  cache: 'no-store' }); REVALIDATE ON A SCHEDULE The sweet spot for most apps: revalidate every N seconds using ISR (Incremental Static Regeneration). Rebuild cache every 60 seconds const data = await fetch('https://lnkd.in/dNaDTpU6', {  next: { revalidate: 60 } }); ON-DEMAND REVALIDATION Published a new blog post? Don't wait 60 seconds. Trigger a cache purge instantly with revalidatePath() or revalidateTag(). import { revalidatePath } from 'next/cache'; export async function publishPost() {  // ...save to DB  revalidatePath('/blog'); // 💥 purge cache instantly } Quick reference: → force-cache = cached forever → revalidate: N = ISR (rebuild every N seconds) → no-store = always fresh Understanding cache layers in Next.js is what separates junior devs from senior engineers. Save this. Your future self will thank you. What's the trickiest caching bug you've ever debugged?

Building modern web applications requires more than just knowing tools — it’s about how you connect them to solve real problems. Here’s my core stack: 🔹 HTML & CSS Structuring and designing responsive, user-friendly interfaces 🔹 JavaScript Adding logic, interactivity, and dynamic behavior 🔹 React Building fast, scalable, and component-based frontends 🔹 Node.js & Express Developing efficient backend systems and REST APIs 🔹 MongoDB Managing flexible, scalable NoSQL databases This stack allows me to build complete, end-to-end web applications from frontend UI to backend logic and database integration. Currently focused on building real-world projects and improving performance, scalability, and clean architecture. #WebDevelopment #FullStack #ReactJS #NodeJS #MongoDB #JavaScript

🔥 Stop Making Repeated API Calls in React! (Use Smart Caching) As a Frontend Developer, one of the most common performance issues I’ve seen is: 👉 Same API getting called again and again This not only slows down the app ⏳ but also increases server load 📉 💡 The solution? Client-Side Caching using TanStack Query (React Query) --- ✅ What is TanStack Query? It’s a powerful data-fetching library that automatically: ✔️ Caches API responses ✔️ Prevents duplicate API calls ✔️ Refetches data in background ✔️ Manages loading & error states --- 💻 Example: Avoid Redundant API Calls import { useQuery } from "@tanstack/react-query"; const fetchUsers = async () => { const res = await fetch("/api/users"); return res.json(); }; export default function Users() { const { data, isLoading } = useQuery({ queryKey: ["users"], // unique cache key queryFn: fetchUsers, staleTime: 5 * 60 * 1000, // cache valid for 5 mins }); if (isLoading) return <p>Loading...</p>; return <div>{data.length} users</div>; } --- 🧠 How it works? - First API call → data stored in cache - Next time → data served from cache (no API call) 🚀 - After "staleTime" → background refetch happens --- ⚡ Why I prefer this in production? 👉 No need to manually manage cache 👉 Built-in request deduplication 👉 Improves performance drastically 👉 Cleaner & scalable code --- 🎯 Pro Tip (Senior Level) Use proper "queryKey" + cache invalidation strategy for dynamic apps --- 💬 Have you used React Query or still managing API calls manually?

🧩 How Full Stack Development Actually Works — in one diagram Most people think a "Full Stack Developer" just knows React + Node.js. But the real picture is much deeper. Every time a user clicks a button, here's what happens behind the scenes: 1️⃣ Frontend — React renders the UI. CSS styles it. JavaScript handles the logic. The browser fires an HTTP request. 2️⃣ Backend — A router catches the request. Business logic processes it. Auth middleware checks if you're allowed in. 3️⃣ Database — A query runs. PostgreSQL, MongoDB, or Redis returns the data. 4️⃣ Response — JSON travels back up the chain. The UI re-renders. The user sees the result in milliseconds. 5️⃣ Infrastructure — CDN, web server, Docker, CI/CD, and cloud hosting make the whole thing fast, scalable, and always-on. A Full Stack Developer owns every single layer of this journey — from the pixel on your screen to the row in the database. #FullStackDevelopment #WebDevelopment #Programming #SoftwareEngineering #React #NodeJS #Backend #Frontend #Developer

What if I told you that a simple misconfiguration in your Next JS application could be slowing down your page loads by up to 30%? When it comes to optimizing performance, one often overlooked aspect is the impact of incorrect getStaticProps usage. This method is used to pre-render pages at build time, but if not used correctly, it can lead to unnecessary re-renders and slow down your application. For example, let's consider a simple blog page that uses getStaticProps to fetch blog posts from an API. If the API is slow to respond, the entire page will wait for the API call to complete before rendering. ```javascript export const getStaticProps = async () => { const response = await fetch('https://lnkd.in/dW6KaPEh'); const posts = await response.json(); return { props: { posts, }, }; }; ``` By using a caching mechanism, like Redis, you can reduce the load on your API and speed up your page loads.
