Built a simple JSON viewer for devs: no ads, no tracking

🚀 Next.js Magic: "getStaticProps" vs "getServerSideProps" If you’ve ever wondered when to use which — here’s the breakdown 👇 🧱 "getStaticProps" — Static Site Generation (SSG) - Runs at build time - Generates HTML + JSON once and reuses it for every request - Super fast — because content is served via CDN - Ideal for: ✅ Blogs ✅ Marketing pages ✅ Docs or FAQs 🕓 Optional: Add "revalidate" to enable Incremental Static Regeneration (ISR) — allowing static pages to update after deployment without a full rebuild. export async function getStaticProps() { const data = await fetch('https://lnkd.in/gMYFrdHq'); return { props: { data }, revalidate: 10 }; } --- 🌐 "getServerSideProps" — Server-Side Rendering (SSR) - Runs on every request - HTML is generated on the server, sent to the browser - Slower than SSG but always up-to-date - Ideal for: ✅ Dashboards ✅ Personalized data (user/session-based) ✅ Real-time content export async function getServerSideProps(context) { const data = await fetch('https://lnkd.in/gcyj7Xhk' + context.query.id); return { props: { data } }; } --- 💡 TL;DR - Use "getStaticProps" when data rarely changes (speed > freshness) - Use "getServerSideProps" when data changes frequently (freshness > speed) ⚡️ Next.js gives you the best of both worlds — choose wisely for performance + user experience. #Nextjs #WebDevelopment #Frontend #React #Performance #JavaScript

YouTube serves 𝐛𝐢𝐥𝐥𝐢𝐨𝐧𝐬. Two lines in DevTools explain 𝘸𝘩𝘺 it feels instant. ⚡ I cracked open DevTools on <code>𝚢𝚘𝚞𝚝𝚞𝚋𝚎.𝚌𝚘𝚖/𝚠𝚊𝚝𝚌𝚑</code> and found the whole playbook hiding in plain sight. 𝐋𝐢𝐧𝐞 𝟏 — 𝚢𝚝𝙸𝚗𝚒𝚝𝚒𝚊𝚕𝙳𝚊𝚝𝚊 (𝐒𝐞𝐫𝐯𝐞𝐫 → 𝐂𝐥𝐢𝐞𝐧𝐭 𝐁𝐚𝐭𝐨𝐧) 🤝 In the HTML, you’ll find this: <code><𝚜𝚌𝚛𝚒𝚙𝚝>𝚟𝚊𝚛 𝚢𝚝𝙸𝚗𝚒𝚝𝚒𝚊𝚕𝙳𝚊𝚝𝚊 = { … }</𝚜𝚌𝚛𝚒𝚙𝚝></code> That blob is the 𝗵𝘆𝗱𝗿𝗮𝘁𝗶𝗼𝗻 𝗽𝗮𝘆𝗹𝗼𝗮𝗱. The server renders the first view and drops structured JSON right into the page, so the client doesn’t have to refetch to paint the UI. First paint feels native because the data is 𝘢𝘭𝘳𝘦𝘢𝘥𝘺 𝘵𝘩𝘦𝘳𝘦. 𝐋𝐢𝐧𝐞 𝟐 — 𝚢𝚝𝚌𝚏𝚐.𝚜𝚎𝚝(...) (𝐎𝐧𝐞 𝐒𝐨𝐮𝐫𝐜𝐞 𝐨𝐟 𝐓𝐫𝐮𝐭𝐡) Right below it, you'll see: <code>𝚢𝚝𝚌𝚏𝚐.𝚜𝚎𝚝({</code><code> "𝙸𝙽𝙽𝙴𝚁𝚃𝚄𝙱𝙴_𝙰𝙿𝙸_𝙺𝙴𝚈": "…",</code><code> "𝙸𝙽𝙽𝙴𝚁𝚃𝚄𝙱𝙴_𝙲𝙾𝙽𝚃𝙴𝚇𝚃": {…}</code><code>})</code> This is the 𝗴𝗹𝗼𝗯𝗮𝗹 𝗰𝗼𝗻𝗳𝗶𝗴 that both the web app and its XHR calls read.Every request to <code>/𝚢𝚘𝚞𝚝𝚞𝚋𝚎𝚒/𝚟𝟷/𝚋𝚛𝚘𝚠𝚜𝚎?𝚔𝚎𝚢=…</code> inherits the same context (client name, version, locale). This ensures features, experiments, and caching stay consistent across tabs. 𝐓𝐡𝐞 𝐓𝐚𝐤𝐞𝐚𝐰𝐚𝐲: 𝐁𝐨𝐨𝐧, 𝐍𝐨𝐭 𝐁𝐚𝐧𝐞 Inline data + a single config pipe = 𝗳𝗮𝘀𝘁 𝗳𝗶𝗿𝘀𝘁 𝗽𝗮𝗶𝗻𝘁, 𝗳𝗲𝘄𝗲𝗿 𝗿𝗼𝘂𝗻𝗱-𝘁𝗿𝗶𝗽𝘀,and predictable 𝗯𝗲𝗵𝗮𝘃𝗶𝗼𝗿 across a sprawling frontend. (And no, the "API key" isn't a secret; the server still checks origin,client version, and context on every call.) #YouTube #DevTools #WebPerformance #Frontend #Engineering #JavaScript

Today, I explored how to make websites more interactive and data-driven by integrating external APIs. Instead of relying on static content, I learned how to fetch and display real-time data — adding depth and functionality to the web experience. 🔹 Objective: Integrate external data sources to provide dynamic, real-time content. 🔹 Key Steps: 1️⃣ Selected a public API (like JSONPlaceholder) and explored its endpoints. 2️⃣ Used the fetch() function in script.js to retrieve data asynchronously. 3️⃣ Parsed the JSON response and dynamically updated the DOM to show live content. 💡 Takeaway: APIs unlock endless possibilities — from fetching user data to displaying live updates. This exercise deepened my understanding of asynchronous JavaScript and real-world data handling. #CognifyzTechnologies #WebDevelopment #JavaScript #APIIntegration #FrontendDevelopment #LearningByDoing #CodingJourney

No more loading spinners that freeze your app! How it works: → Wrap your async component with 𝗥𝗲𝗮𝗰𝘁.𝗦𝘂𝘀𝗽𝗲𝗻𝘀𝗲 → Use a "fallback" component (e.g., a spinner or skeleton screen) while data is loading → Once data is ready, React automatically swaps in the fully loaded component Benefits: • Improved user experience—only the relevant part of the UI waits for data • Cleaner code—no more manual loading states or conditional rendering • Seamless integration with React Query, SWR, or other data-fetching libraries Example: ``` <Suspense fallback={<Spinner />}> <AsyncComponent /> </Suspense> ``` Tip: Combine Suspense with 𝗥𝗲𝗮𝗰𝘁.𝗹𝗮𝘇𝘆 for even better performance. Load components only when they’re needed!

I'm converting my vanilla HTML/CSS/JS project to React via Vite without any downtime. Here's how: I let the vite CLI overwrite my files. It really only affected my index.html that got overwritten. I removed the boilerplate components and styling that Vite added. Then it's as simple as copy/pasting in the old HTML structure into index.html. Add in the old CSS and JS files in src/, and add in the needed HTML to link the files. You will now have a mix of vanilla code and React + TS code. Now, move a part of the HTML into a React component, and let React render the HTML instead. Do it step by step. In my case, I also load in data. I will convert that into TypeScript, import it at the top of the component stack, and prop drill it down as needed. I'm using about 0% AI for all of this, because it just goes faster to review the code as I move it.

🔁 State Lifting in React | The Smart Way to Share Data Between Components. Ever had two React components that needed to share the same data, but didn’t know how? 🤔 That’s where the concept of State Lifting comes in, one of React’s most elegant patterns. 🧩 What Is State Lifting? When two or more components need access to the same data, you lift that state up to their closest common parent. The parent manages the data, and the children receive it through props. This keeps data centralized and consistent. 🧠 Let’s See an Example. Now look the example code below, let’s say we have two child components one to input data, and one to display it. Without lifting state, they can’t “talk” to each other directly. 🧭 Here, both child components share the same state managed by their parent. 🚀That’s state lifting in action. 🧠 Best Practice Lift state only when needed, not every piece of state should live in the parent. If many components need the same state → consider React Context. Keep the flow of data unidirectional (top → down). 💬 Final Thought: State lifting teaches one of React’s golden rules. 👉 Share state by moving it up, not across. #ReactJS #MERNStack #FrontendDevelopment #WebDevelopment #ReactPatterns #ReactHooks #JavaScript #CleanCode #LearnReact #SoftwareEngineering

💻 It all started with a simple frustration... Every time I worked with APIs, I’d end up copying messy JSON into random online formatters — Some were slow, others spammed me with ads, and a few even sent data to their servers. One day, while debugging a client’s API, I thought — “Why am I trusting sensitive data to some random site?” That’s when I decided to build my own solution. 🔥 JSON Formatter Online — a free, privacy-friendly, and super-fast JSON formatter built for developers who value speed and simplicity. ⚡ Instantly formats and validates JSON 🔒 Runs 100% in your browser (no uploads!) 🧩 Clean, ad-free UI 🌗 Dark mode for late-night debugging I didn’t plan to launch it publicly at first—it was just a side project to make my own workflow faster. But when I shared it with a few dev friends… they started using it daily. Now it’s live for everyone. → https://lnkd.in/geiMP6qy Here’s what it looks like 👇 (attach your screenshot image here) Next up, I’m planning: JSON → CSV converter Shareable links Auto error detection Sometimes the best tools are born out of personal pain.
