Real-Time Multiplayer Tic Tac Toe with WebSockets

Gamifying React: Building an Idle Clicker 🎮💰 Can you build a high-performance game engine using standard web technologies? I took on the challenge with my latest project: Idle Clicker. While it looks like a fun game, under the hood, it’s a masterclass in state management and performance optimization: 🔹 Dynamic Scaling: Implemented mathematical formulas to handle exponential growth for upgrades and costs. 🔹 Performance First: Managed rapid state updates (clicks + auto-income) without causing UI lag, ensuring a smooth 60fps experience. 🔹 React Logic: Utilized hooks and custom logic to bridge the gap between "web app" and "game engine." This project proves that whether it's a data dashboard or a game, I focus on building responsive, logic-driven systems that keep users engaged. 🔗 Try it here (Warning: Addictive): https://lnkd.in/dVbqD6Aj #ReactJS #GameDev #WebDevelopment #Logic #JavaScript #Frontend #CodingChallenge #InteractiveDesign

Stop using useEffect for everything. These React hooks exist. Most devs forget them. useMemo — cache expensive calculations. You're recalculating on every render. useMemo only runs when dependencies change. Big performance win. useCallback — stable function references. Passing functions as props without this? You're creating a new function every render and breaking React.memo. useReducer — built-in state management. When useState gets messy with 3+ related values, useReducer brings order. Think Redux, but already in React. useRef — more than just DOM refs. Store any mutable value that persists across renders without triggering a re-render. Timers, previous values, flags. useId — SSR-safe unique IDs. Generating IDs for labels and inputs? useId handles unique IDs automatically, even with server-side rendering. Most devs reach for useState and useEffect for everything, then wonder why their app feels slow. The hooks are already there. You just have to use them. Which hook do you wish you'd learned earlier?

WUHDUL! alright this was a fun one to build my take on the classic Wordle, but built from scratch with a clean UI and smooth gameplay 6 attempts. 5-letter word. same chaos when you’re on your last guess. focused a lot on making it feel fast and polished. everything runs fully in the browser, no backend (all client sided), just pure frontend work using React, TypeScript and Vite also added small things like dark mode, responsive layout, and a proper word system so it actually feels balanced here’s a quick demo 👇 https://lnkd.in/gtgNSXYx would love to know what you think you can check it out here! #react #frontend #webdev #projects #buildinpublic

#Day486 of #500DaysofCode 🚀 Built a Multi-Game React App from Scratch 🎮⚛️ Excited to share one of my recent frontend development projects — a Multi-Game Arcade Web App built with React.js. This project combines game logic, UI engineering, modular styling, and component architecture into one interactive platform. 🎯 Games Included ✅ Tetris ✅ 2048 ✅ Chinese Checkers 🛠️ What I worked on 🔹 Dynamic game selector dropdown for switching between multiple games 🔹 Reusable header and layout components 🔹 Complex Chinese Checkers board logic & move validation 🔹 Responsive Tetris UI with score and control panels 🔹 Smooth 2048 tile merge logic and animations 🔹 Modular CSS for scalable component styling 💡 Key Learnings This project helped me strengthen my skills in: React component architecture State management with hooks Game loop and movement logic CSS modules & responsive layouts UI animations and transitions Writing scalable frontend code The most exciting part was bringing multiple classic games into a single seamless React experience while keeping the code modular and maintainable. Would love to hear your thoughts on: 👉 Which game should I add next? I’m thinking Snake 🐍, Sudoku 🧩, or Chess ♟️ #ReactJS #FrontendDevelopment #JavaScript #WebDevelopment #GameDevelopment #CSS #UIUX #Programming #Coding #Projects #SoftwareEngineering

🚀 Just Built a Memory Game with React.js! Excited to share one of my recent projects — a fully interactive Memory Game built using React.js 🎯 🔹 Features: - Clean and responsive UI - Smooth card flip animations - Game logic using React state & hooks - Dynamic score tracking - Optimized performance for better user experience This project helped me strengthen my understanding of: 💡 Component-based architecture 💡 State management in React 💡 Event handling & logic building I’m continuously working on improving my frontend development skills and building more interactive projects like this. demo: https://lnkd.in/gBdwh_Yn 🎥 Check out the demo video below! #ReactJS #FrontendDevelopment #WebDevelopment #JavaScript #Projects #LearningByDoing

♟️ Checkmate! Just finished building a fully functional Chess Engine with React & TypeScript. I’m excited to share a project I’ve been working on: a high-performance, real-time Chess Web Application. Building this was a deep dive into complex state management and game logic. Instead of just rendering a board, I focused on creating a robust "brain" for the game that handles: Move Validation: Real-time calculation of legal moves for all pieces. Check/Checkmate Detection: Logic to verify king safety and end-game states. Pawn Promotion: A custom UI overlay for choosing pieces when a pawn reaches the 8th rank. Responsive UI: A fluid design that works as well on mobile as it does on desktop. 🛠️ The Tech Stack: React (Functional Components & Hooks): For a snappy, reactive interface. TypeScript: To ensure type safety across complex piece interfaces and board states. CSS3: Custom styling with CSS Grid and glassmorphism effects for a modern feel. One of the biggest challenges was ensuring the game engine could accurately predict "check" by simulating moves on a temporary board before allowing the user to commit to a turn. This project really sharpened my skills in algorithmic thinking and React performance optimization. I'm always looking to improve—what features should I add next? (Move history, Timer, or maybe an AI opponent?) You may also try👇🏻 https://lnkd.in/gvg3A4nY #WebDevelopment #ReactJS #TypeScript #Chess #SoftwareEngineering #Frontend #CodingProject #JavaScript

🚀 DAY 115 — Built a Multi-player Real-Time Chess.com Clone ♟️ I recently developed a real-time Chess.com-inspired web application, focused on multiplayer gameplay and accurate game logic. 🔹 Key Features: • Live multiplayer gameplay using WebSockets • Interactive drag-and-drop chessboard • Move validation and game state management using chess.js • Turn-based gameplay with player role handling 🔹 Tech Stack: • Frontend: HTML, CSS, JavaScript • Backend: Node.js, Express • Real-time Communication: Socket.IO 🔹 What I Learned: • Implementing real-time communication between clients • Synchronizing game state across multiple users • Handling complex game logic and edge cases • Structuring backend systems for multiplayer applications 📌 Next Steps: Adding matchmaking and game timers.

🚀 Built a Simple OTP Generator using React! I recently worked on a small project to strengthen my understanding of React hooks, especially useState and useEffect. 🔐 Project Highlights: Generates a secure 6-digit OTP Countdown timer (5 seconds) for OTP expiry Auto-disables the button during active timer Displays expiry message once time runs out Clean and interactive UI 💡 What I learned: Managing state effectively with useState Handling side effects and timers using useEffect Writing clean and testable React components Improving user experience with conditional rendering This project may be simple, but it helped me understand how real-world features like OTP systems work behind the scenes. Looking forward to building more such practical projects! 💻✨ #ReactJS #WebDevelopment #Frontend #JavaScript #LearningByDoing #CodingJourney

If your React app still re-renders… this is why useMemo → caches values, not renders Use when computation is expensive Not for “just in case” optimization useCallback → stabilizes function reference Useful only when passing to memoized children Not for wrapping everything React.memo → skips render if props are same (by reference) Works only if props are stable Breaks if you create new objects/functions every render The truth 👇 They don’t improve performance on their own They only work if you control identity New object = re-render New function = re-render React doesn’t care if values look same Only if they are the same reference If you don’t control identity You don’t control rendering #reactjs #frontend #javascript #webdevelopment #reactperformance #softwareengineering #coding #devtips
