Choosing Between Virtualization, Infinite Scroll, and Pagination for Frontend Rendering

Why settle for a template when you can build your own content infrastructure? I’ve launched my new portfolio. While it might look like a simple project showcase, underneath there’s an engine that allows me to manage all the data and how it's presented. I decided to move away from ready-made solutions to avoid watermarks and add more personality, using a modern stack that allows me to manage content from anywhere in real-time: - Next.js: Leveraging its hybrid architecture (SSR/CSR) for instant loading without sacrificing interactivity. - Payload CMS: A code-based Headless CMS that gives me full control over my games' data modeling. - TypeScript: Strict typing to ensure a clean and scalable architecture. - Vercel: Taking advantage of its free (non-commercial) tier for a simple and cost-effective deployment. I designed this space to document the development of each project. On the dedicated pages, I summarize several key aspects of the build process. In the coming weeks, I’ll be posting individual showcases for each of the projects.

Built something this week that actually got me excited ➜ a Finance Dashboard called FinVault 🚀 Here's what's packed into it: 🏗️ Built with React 18 + Redux Toolkit + Tailwind CSS 📊 Interactive charts → monthly cash flow trends, spending breakdowns by category 💳 Full transaction management → add, edit, delete, search, filter, and sort 🔐 Role-based UI → switch between Viewer and Admin with completely different experiences 💡 Insights section → savings rate, expense ratio, month-over-month comparisons, and smart observations generated from real data 💾 Data persists across sessions via localStorage 📤 Export filtered transactions as CSV A few things I focused on beyond just making it work: → Custom hook (useFilteredTransactions) so filter logic is written once and reused everywhere → Pure utility functions for all data computation easy to test, easy to reuse → Redux slices kept clean by separating UI state from data state → Empty states, loading transitions, and keyboard shortcuts handled throughout The dark UI was intentional wanted something that actually looks good to use, not just functional. The best way to learn is to just build things. 💻 🔗 Try it yourself: https://lnkd.in/dfra7-Sx #ReactJS #Redux #TailwindCSS #Frontend #WebDevelopment #JavaScript #UIDesign #BuildInPublic

🚀 From Idea to Interface—Progress You Can See. #Day2 of building DataVault—and today’s milestone feels real. Alhamdulillah, I’ve successfully converted the entire UI into working code using React and Tailwind CSS. What started as a concept is now a fully functional front-end with a working dashboard. 💻 What’s done: • Complete UI implementation using React + Tailwind CSS • Clean, responsive design now fully interactive • Dashboard functionality is up and running smoothly This is a big step—because now DataVault isn’t just an idea or a design… it’s something you can actually use. 🔐 What’s next: My next focus is implementing authentication to make the platform secure and accessible for real users. The goal is to ensure anyone can safely use DataVault to manage their data with confidence. ⏳ The 7-Day Challenge continues… I’m confident that within the next 2 days, this will evolve into a fully working application. 🤝 I’d love your input: If you have suggestions, features you’d like to see, or feedback—please share.

useEffect is not componentDidMount. It's been five years since hooks came out and I still see this in almost every codebase I touch. The pattern looks like this: a component mounts, someone needs to "do something on mount," so they write useEffect with an empty dependency array and call it a day. Fetch data, set up a listener, update some external thing — all crammed into one useEffect that does three unrelated jobs. Then it grows. Someone adds a cleanup function that doesn't clean up properly. Someone adds another dependency but doesn't understand why the effect now runs twice. Someone wraps the whole thing in an if statement because it fires when it shouldn't. Six months later you're staring at a 40-line useEffect and nobody wants to touch it. Here's what helped me stop writing these: → Most "on mount" effects are actually data fetching. You don't need useEffect for that anymore. TanStack Query, SWR, or even Next.js server components handle it better. Less code, built-in caching, no race conditions. → Event listeners and subscriptions? Separate useEffect for each one. Not one mega-effect. One listener, one cleanup, one purpose. Boring? Yes. Debuggable? Also yes. → If your effect "synchronizes" with some prop or state — check if you actually need it. Half the time a derived variable or useMemo does the job without the extra render cycle. The worst version I've seen: a useEffect that watched a state variable, then set another state variable, which triggered another useEffect. Two re-renders for something that could've been one line of code. If your useEffect has more than 10 lines, something probably went wrong somewhere. #ReactJS #TypeScript #FrontendDevelopment

Stop using useEffect and useState to fetch data. Seriously. Next.js 16 just made your favorite global state management libraries largely obsolete for basic fetching. Okay, maybe "obsolete" is a strong word. Tools like React Query still have a place for complex client mutations. But for 90% of what we build, the data fetching lifecycle has entirely changed. I recently migrated a dashboard to the new Next 16 pattern, and the amount of boilerplate I deleted was staggering. We used to build fragile client-side pipelines: → Component mounts → useEffect fires → loading state toggles → fetch happens → state updates It was messy, prone to race conditions, and caused terrible network waterfalls. Next 16 formalizes a much cleaner flow. First, you initiate your fetch directly in a Server Component. You don't even have to worry about over-fetching because Next automatically memoizes and dedupes the requests across the tree. Second, instead of awaiting everything at the top and blocking the initial page render, you just pass that raw Promise down to your Client Component as a prop. Finally, you unwrap that Promise inside the Client Component using React's new use() hook. Why is this such a massive upgrade? 🚀 Because passing a Promise from server to client natively integrates with Suspense. When you call use(promise), you don't need to manually track isLoading flags anymore. The UI just waits, gracefully shows your fallback boundary, and renders the data when it's ready. It feels weird at first. Passing an unresolved promise down the component tree feels like breaking a rule we were all taught in React 101. But once you see how it strips away dozens of lines of state management and lifecycle hooks, you realize this is how React was always meant to feel. We are finally moving away from managing the mechanics of fetching, and getting back to just building UI. Have you tried passing promises to the use() hook yet, or are you still holding onto your useEffect blocks? 👇 #Nextjs #React #WebDevelopment

I spent months building CLI tools. Every time I started a new one, I wrote the same boilerplate. Input parsing. Layout logic. State management. Re-renders. All from scratch. There was no framework for this. So I built one. Today I am open-sourcing TermUI. A TypeScript framework for building terminal apps. Think Next.js, but for your terminal. Here is what you get out of the box: - JSX support with useState, useEffect, useRef, useContext, and useAsync - Flexbox layout engine in pure TypeScript, no C extensions, no curses bindings - File-based routing with typed params and route guards - Zustand-like global state with selector subscriptions - Terminal Style Sheets for CSS-like theming with variables and pseudo-classes - Spring-physics and easing-based animations - VirtualList that renders 1,000,000 rows as fast as 10 - Hot-reload dev server that restarts in under 200ms on every file save - A test renderer so you can write headless component tests without a real terminal You start with one command: npx create-termui-app my-app You get a full project. Dev server, routing, state, widgets, all wired. The architecture is layered. Core, widgets, JSX, store, router, UI. Every package is independent. Use only what you need. It ships on npm as @termuijs/core. I am building this in public. Shipping the real thing, not a side project demo. If you build CLI tools, developer dashboards, or terminal apps, this is for you. GitHub link and npm package in the first comment. What would you build with a terminal framework like this?

Let’s talk about useEffect. Not just how to use it… but how to use it properly. Because this is where a lot of frontend issues start. First thing to understand: useEffect is for side effects. That means anything outside the normal render flow: – API calls – subscriptions – timers – interacting with the DOM It’s not a general-purpose tool for logic. Where most people get it wrong: They treat useEffect like: “run this code when the component loads” And then you start seeing things like: – multiple API calls – infinite loops – unnecessary re-renders – state updating in circles A simple example: If you do this: useEffect(() => { fetchData(); }); That runs on every render. Now imagine what happens when state updates… The correct approach is to be intentional: – run once → use [] – run on change → add specific dependencies But here’s the shift that changed things for me: I stopped asking “where can I use useEffect?” And started asking “do I even need useEffect here?” Because in many cases, you don’t. Instead: – derive values directly during render – use event handlers for interactions – use tools like React Query (TanStack Query) for data fetching React Query handles: – caching – background updates – loading & error states – request deduplication So you don’t have to manually manage all of that inside useEffect. That shift alone removes a lot of bugs. useEffect is not a “run code” tool. It’s a synchronisation tool. Once you understand that… your code becomes simpler and more predictable. #React #ReactQuery #Frontend #WebDevelopment #JavaScript #SoftwareEngineering

Time for another #MondayTips! Today we talk about .map. Let’s say you fetch data from a route. It comes back in one TypeScript shape. Then you pass it into your frontend… and suddenly things don’t quite line up. Different names, slightly different structure, maybe extra fields you don’t even need. So what do you do? You don’t bend your UI around it. You transform the data properly using .map(). If most of the structure works and you just need to add a few , you can extend it, using a spread operator to mention the previous properties, and add new properties to it: let newObject = array.map((item) => ({ ...item, newValue1: item.backendValue, newValue2: item.anotherBackendValue, })); This keeps everything that already works and just adjusts what you need. If the backend shape is completely off for what your frontend needs, add an object inside the map method and the new properties let newObject = array.map((item) => ({ newValue1: item.backendValue, newValue2: item.anotherBackendValue, })); This way you'll be able to shape your new object into what you need to feed into your frontend. What would you like to know about next? Let me know in the comments. I will take a look and find the solution for future weeks. #dev #learningprogramming
