Top State Management Tools for React (Next.js) in 2025

State management is at the core of every modern React application. Whether you're building a small personal project or a complex enterprise dashboard, choosing the right tool can drastically improve your code maintainability, performance, and developer experience.In this post, I’ll break down the top state management solutions for React and Next.js in 2025 — including when to use each one.🔹 1. React Context API (Built-in, Minimal)Best for: Simple global state like theme, language, or auth user.React’s built-in Context API is great when your state is minimal and doesn’t change often. But for larger or performance-sensitive apps, it can lead to unnecessary re-renders.✅ Pros:No extra dependenciesPerfect for small, static state⚠️ Cons:Performance issues with frequent updatesCan get messy without proper structure💡 Tip: Pair it with useReducer to better handle complex logic.🔹 2. Zustand (Minimal, Modern, Powerful)Best for: Medium to large apps that need a simple yet scalable solution.Zustand is a small, fast, and scalable state management library built by the creators of Jotai and React-Three-Fiber. It works great with both React and Next.js — even in SSR.✅ Pros:Super simple API (create() stores)No Provider neededSupports partial updates, async actions, middleware⚠️ Cons:You’ll still need something like React Query for data fetching/state sync// Example Zustand store const useStore = create((set) => ({ count: 0, increase: () => set((state) => ({ count: state.count + 1 })), })); 🔹 3. Redux Toolkit (Battle-Tested, Structured)Best for: Large-scale apps or teams that need strict architecture and dev tools.Redux got a major revamp with Redux Toolkit, which simplifies setup, reduces boilerplate, and offers great TypeScript support. Still widely used in enterprise apps.✅ Pros:Predictable, scalableStrong ecosystem (Redux DevTools, middleware, etc.)Good TypeScript support⚠️ Cons:More boilerplate than Zustand or JotaiOverkill for small/medium apps🔹 4. Jotai (Atomic, Fine-grained)Best for: Component-level, fine-grained reactivity without global bloat.Jotai is a modern state management library based on atomic state. It lets you manage deeply nested or reactive state in a clean, minimal way.✅ Pros:Atomic updates = high performanceGreat for local or scoped stateFull SSR support⚠️ Cons:Smaller ecosystemMay require a mindset shift from global stores🔹 5. React Query (or TanStack Query)Best for: Remote data synchronization (API fetching, caching, and mutations).React Query is technically not a state manager — it's a server-state manager. It’s perfect for apps where the main state lives on the server (APIs, databases).✅ Pros:Automatic caching, refetching, paginationBuilt-in loading/error statesExcellent DevTools⚠️ Cons:Not for UI state (use Zustand or Context for that)🔚 Final ThoughtsEvery app has different needs. Here’s a quick cheat sheet:Use CaseBest ToolSmall, simple stateReact ContextMid-sized app, local/global mixZustand or JotaiLarge app with strict structureRedux ToolkitRemote data fetchingReact QueryIf you're working with Next.js, all of these tools can be used effectively — just make sure to account for SSR/SSG where necessary.Which one are you using in your current project? I’ve personally leaned toward Zustand + React Query for most of my recent work. Clean, flexible, and efficient.Let me know if you want a deep dive on any of these!

🧠 Problem Solving Patterns Every Developer Should Know

Whether you're debugging a stubborn bug, designing an algorithm, or architecting an application, strong problem-solving skills are at the heart of being a great developer. While every problem is unique, many share common underlying patterns. Recognizing and mastering these patterns can save time, reduce stress, and level up your coding game.Here are some essential problem-solving patterns to keep in your toolkit:1. Sliding WindowUseful for problems involving arrays or strings, especially when you're working with a contiguous subset of elements.Use when:You need to find the maximum, minimum, or average of a subarray or substring of fixed or dynamic length.Example:Longest substring without repeating charactersMaximum sum subarray of size k2. Two PointersA versatile pattern where two pointers move through a data structure to compare or track elements.Use when:You need to compare pairs in a sorted array, or remove duplicates in place.Example:Reverse a stringFind pair with target sum in sorted array3. Fast and Slow Pointers (Tortoise and Hare)A variation of the two-pointer technique. Great for detecting cycles in linked lists or similar structures.Example:Detecting loops in a linked listFinding the middle of a linked list4. Divide and ConquerBreak the problem into smaller sub-problems, solve them independently, and combine the results.Use when:Recursive or tree-based problems; improves time complexity significantly in some cases.Example:Merge SortBinary Search5. BacktrackingTry all possible solutions recursively, and backtrack when you hit a dead end. Think of it as depth-first search with a constraint.Use when:You need to generate or search through combinations or permutations with constraints.Example:N-Queens problemSudoku solver6. Dynamic ProgrammingBreak the problem into sub-problems and remember solutions to avoid redundant work.Use when:You find overlapping subproblems or need to find the optimal solution under constraints.Example:Fibonacci sequence (with memoization)Knapsack problem7. GreedyMake the locally optimal choice at each step in the hope it leads to the globally optimal solution.Use when:A problem has a clear "greedy property" — you can prove that local choices lead to the best outcome.Example:Activity selectionMinimum number of coins8. Graph Traversal (BFS / DFS)Used for problems involving networks, maps, or tree structures.Use when:You're exploring paths, finding shortest paths, connected components, or checking if a route exists.Example:Maze solverSocial network friend suggestion🔁 Practice Makes Patterns StickThe best way to internalize these patterns is to practice them across different problem types. Platforms like LeetCode, Codeforces, and HackerRank are great for this.Start identifying which pattern a problem belongs to — soon, you'll be solving things faster and with more confidence.

🚀 What is React Native? A Beginner-Friendly Guide

In the world of mobile app development, one name that has revolutionized the industry is React Native. Developed by Facebook, React Native allows developers to build fully functional mobile applications using JavaScript and React — but here’s the magic: it compiles to native code, meaning your app runs just like a traditional iOS or Android app.🌟 Why React Native?The key appeal of React Native lies in its “write once, use everywhere” philosophy. You write your code in JavaScript (with JSX) and React Native compiles it into platform-specific native components for both iOS and Android. This drastically reduces development time and cost.📱 How Does It Work?React Native bridges the gap between JavaScript and native APIs using a special layer called the bridge. The bridge lets JavaScript code communicate with native modules like the camera, GPS, or Bluetooth.This means:You write UI components using React.React Native uses native views (like UIView for iOS or View for Android) under the hood.You get near-native performance with JavaScript development speed.🛠️ Key Features✅ Cross-platform: One codebase for both iOS and Android.🔁 Hot Reloading: See code changes instantly without recompiling.💡 Rich Ecosystem: Integrate with native modules and third-party libraries.📦 Modular Architecture: Reuse components and separate logic easily.🧪 Strong Community: Backed by Facebook and a huge open-source community.💬 Popular Use CasesReact Native is great for:Startups building MVPs quickly.Companies maintaining both iOS and Android apps.Apps with real-time data (e.g., chat, social media, or dashboards).Popular apps built with React Native include:FacebookInstagramShopifyDiscordUber Eats🔧 Basic ExampleHere’s a simple counter app in React Native:import React, { useState } from 'react'; import { View, Text, Button } from 'react-native'; export default function App() { const [count, setCount] = useState(0); return ( <View style={{ padding: 40 }}> <Text style={{ fontSize: 24 }}>Count: {count}</Text> <Button title="Increase" onPress={() => setCount(count + 1)} /> </View> ); }🧩 React Native vs. Flutter vs. NativeFeatureReact NativeFlutterNative (Swift/Kotlin)LanguageJavaScriptDartSwift/KotlinUI PerformanceGreatExcellentBestCommunity SupportStrongGrowingStrongLearning CurveEasier for JS devsNew syntax to learnSteeperEcosystemHuge (npm)Strong (pub.dev)Official tools🧠 Final ThoughtsReact Native brings the best of both worlds: native performance and JavaScript productivity.

Vebhook chi?Xozir shu blogda tepadagi savolga jovob topishga xarakat qilamizSo'rovnoma (Polling)Restoranda ovqatga buyurtma berayotganda, ofitsiantdan buyurtmangiz tayyor yoki yo'qligini doimiy ravishda so'rash maqsadga muvofiq emas va uyatli ham dur.Ushbu stsenariy so'rovning(polling) samarasizligini ko'rsatadi, bu usul mijoz oldindan belgilangan vaqt oralig'ida serverdan ma'lumotlarni qayta-qayta so'raydi.So'rov (polling) bir xizmat yangi ma'lumotlarni tekshirish uchun boshqa xizmatga takroriy so'rovlar yuborishni o'z ichiga oladi.So'rovning asosiy xususiyatlari:Takroriy so'rovlar: So'rovda mijoz muntazam ravishda serverga yangi ma'lumotlar mavjudligini so'rab so'rovlar yuboradi. Bu yondashuv doimiy ravishda "Men uchun yangi narsa bormi?" kabi so'rovlar junatadi.Resursga talabgor: so‘rovlar resurslarni ko‘p va samarasiz ketishidur. U yangilanishlar mavjud bo'lmagan taqdirda ham tarmoqni kengligi va server resurslarini sarflaydi.O'tkazib yuborilgan yangilanishlar: so'rovnoma real vaqtda yangilanishlarni o'tkazib yuborishga olib kelishi mumkin. Mijoz yangilanishlarni oldindan belgilangan vaqt oralig'ida tekshirganligi sababli, u ma'lumotlar mavjud bo'lganda darhol bilmasligi mumkin.VebhooklarVebhooklar so'rovga(polling) yanada samaraliroq va real vaqtda alternativa taklif qiladi. Vebhuklar qanday ishlaydi:Callback URL-manzil: Vebhuk yordamida siz bir tizim yangi ma'lumotlar mavjud bo'lganda boshqa tizimni xabardor qilish uchun foydalanadigan qayta qo'ng'iroq URL manzilini o'rnatasiz. Ushbu yondashuv o'rnatilgan bildirishnoma tizimiga o'xshaydi, u erda server "biror narsa sodir bo'lganda sizga xabar beraman" deb aytadi.Ma'lumotlarni yetkazib berish: Vebhook ma'lumotlarni real vaqt rejimida yangilanishini ta'minlab, ular mavjud bo'lishi bilanoq qabul qiluvchi xizmatiga yuboradi. Bu vebhuklarni o'z vaqtida bildirishnomalar kerak bo'ladigan stenariylar uchun qo'l keladi.Samaradorlik va real vaqtda yangilanishlar: Vebhuklar so'rovdan ko'ra samaraliroqdir, chunki ular takroriy so'rovlarga bo'lgan ehtiyojni yo'q qiladi. Ular real vaqt rejimida yangilanishlarni ta'minlaydi, bu ularni to'lov tizi, CI/CD platformalari va zudlik bilan yangilashni talab qiladigan boshqa xizmatlar kabi ilovalar uchun ayni qo'l keladi.So'rov va Vebhuklardan qachon foydalanish kerakHar bir yondashuv o'z foydalanish holatlariga ega:So'rov:Ma'lumotlarni tez-tez yangilash: Agar real vaqtda ma'lumotlarni yangilash kerak bo'lmasa va ma'lumotlar tez-tez yangilanib tursa, so'rov bunga yechim bo'la oladi. Har bir hodisa uchun veb-huklarni yuborish resurs talab qilishi mumkin. Misol uchun, foydalanuvchi bazasi haqida xabar bermoqchi bo'lgan ijtimoiy media ilovasi, agar ko'p foydalanuvchilar ketma-ket ro'yxatdan o'tgan bo'lsa, vebhuklarga to'lib ketishi mumkin.Moslashuvchanlik: Sinxronlash chastotasini yangilangan maʼlumotlarga qanchalik tez-tez kerakligi asosida sozlashingiz mumkin.Veb-huklar:Haqiqiy vaqtda yangilanishlar: Vebhook real vaqtda yangilanishlar muhim bo'lgan stsenariylar uchun juda mos keladi. Masalan, toʻlov bildirishnomalari, chat ilovalari va darhol bildirishnomalarni talab qiladigan har qanday xizmat.Resurslardan samarali foydalanish: Vebhook so'rovga qaraganda resurslardan foydalanish nuqtai nazaridan samaraliroq. Ular ma'lumotlarning takroriy so'rovlarsiz real vaqt rejimida yetkazilishini ta'minlaydi.Xo'sh, siz ilovangizda So'rov yoki Vebhook-dan foydalanganmisiz?

An Introduction to Three.js: Creating Stunning 3D Visualizations for the Web

In the world of web development, making rich, interactive 3D graphics is no longer reserved for specialized software. Thanks to Three.js, developers can now create stunning 3D visuals right in the browser using JavaScript. Whether you're building games, interactive simulations, or just adding some flair to your website, Three.js offers a powerful, yet easy-to-use, framework for bringing 3D experiences to life on the web.In this blog, we’ll take a closer look at Three.js, explore its capabilities, and walk through a simple example to help you get started.What is Three.js?Three.js is an open-source JavaScript library that simplifies the process of creating and rendering 3D graphics in the browser. Built on top of the WebGL API, which is responsible for rendering 3D graphics in browsers, Three.js abstracts away many of the complexities of working with WebGL directly. This makes it easier for developers to create 3D scenes, animations, and interactive visualizations without deep knowledge of lower-level graphics programming.Core Features of Three.jsThree.js offers a wide range of features for developers, some of which include:3D Geometry: Easily create 3D objects like cubes, spheres, and complex meshes.Lights and Shadows: Add realistic lighting to your scene, and configure different shadow effects.Materials and Textures: Apply materials (like basic, Lambert, and Phong) and textures to objects for a more realistic look.Camera and Viewports: Control the camera position, field of view, and other parameters to view the 3D world.Animation: Create animations for objects and scenes, including keyframe animation and tweening.Interactivity: Add interactivity using mouse and touch input, allowing users to interact with 3D objects.Post-processing: Apply special effects like bloom, depth of field, and more after rendering the scene.These features, combined with an active community, extensive documentation, and examples, make Three.js a fantastic choice for anyone looking to build 3D experiences on the web.How Does Three.js Work?Three.js simplifies the process of rendering 3D scenes by handling the complex parts of WebGL for you. The library provides an easy-to-understand API for working with scenes, cameras, objects, and renderers. Here’s a breakdown of the key components:Scene: The environment that contains all your objects, lights, and cameras.Camera: The viewpoint from which the scene is viewed. Three.js provides multiple camera types (e.g., perspective and orthographic) to suit different needs.Renderer: The engine that renders the scene to the browser’s canvas using WebGL or other rendering methods like CSS3D.Object3D: The basic building block for any 3D object in Three.js. This can be a simple object like a cube or a more complex 3D mesh.Lights: Different types of light (ambient, point, directional) can be used to illuminate the objects in the scene.Materials and Textures: Materials define how objects react to light, and textures add detail to these materials, giving them a more realistic appearance.Basic Example: A Rotating CubeLet’s go through a simple example to help you get started with Three.js. This example will render a rotating cube in the browser.Set up your project: First, you need to include Three.js in your project. You can download it from Three.js’s official website or use a CDN link. Here's an example using a CDN:<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>Three.js Example</title> <style> body { margin: 0; overflow: hidden; } canvas { display: block; } </style> </head> <body> <script src="https://cdnjs.cloudflare.com/ajax/libs/three.js/r128/three.min.js"></script> <script> // 1. Create scene const scene = new THREE.Scene(); // 2. Create camera const camera = new THREE.PerspectiveCamera(75, window.innerWidth / window.innerHeight, 0.1, 1000); // 3. Create renderer const renderer = new THREE.WebGLRenderer(); renderer.setSize(window.innerWidth, window.innerHeight); document.body.appendChild(renderer.domElement); // 4. Create cube geometry const geometry = new THREE.BoxGeometry(); const material = new THREE.MeshBasicMaterial({ color: 0x00ff00 }); const cube = new THREE.Mesh(geometry, material); scene.add(cube); // 5. Set camera position camera.position.z = 5; // 6. Animation loop function animate() { requestAnimationFrame(animate); // Rotate cube cube.rotation.x += 0.01; cube.rotation.y += 0.01; // Render scene renderer.render(scene, camera); } animate(); </script> </body> </html>Explanation of the Code:Scene Creation: const scene = new THREE.Scene(); initializes the scene where all 3D objects will be added.Camera Setup: const camera = new THREE.PerspectiveCamera(75, window.innerWidth / window.innerHeight, 0.1, 1000); sets up the camera with a field of view (FOV) of 75 degrees, and a near and far plane of 0.1 and 1000 units respectively.Renderer: const renderer = new THREE.WebGLRenderer(); sets up the WebGL renderer to display the scene in the browser.Cube Creation: We create a cube using THREE.BoxGeometry and apply a basic green material using THREE.MeshBasicMaterial.Animation: The animate function continuously rotates the cube around its x and y axes and renders the updated scene every frame using requestAnimationFrame.Advanced Use Cases for Three.jsWhile the above example is a simple starting point, Three.js can handle much more advanced visualizations:3D Games: You can use Three.js to build fully interactive 3D games, complete with physics engines and real-time interaction.Virtual and Augmented Reality: With the help of the WebVR and WebXR APIs, Three.js can be used to create immersive VR/AR experiences directly in the browser.Data Visualizations: Three.js is commonly used to create interactive, real-time 3D data visualizations, especially in fields like data science and analytics.Animations and Simulations: Whether it’s simulating physics or creating smooth animations, Three.js makes it easy to animate objects in 3D space.3D Models and Textures: Three.js supports importing 3D models from formats like OBJ, GLTF, and FBX, and applying textures and lighting for realistic visuals.Resources to Learn MoreOfficial Three.js Documentation: https://threejs.org/docs/Three.js Examples: https://threejs.org/examples/Three.js GitHub Repository: https://github.com/mrdoob/three.js/Community and Tutorials: There are numerous tutorials and courses available on platforms like YouTube, Udemy, and freeCodeCamp that dive deeper into Three.js.ConclusionThree.js is an incredibly powerful library that opens the door for developers to create immersive, interactive 3D experiences directly in the web browser.

Top Next.js Problems and How to Solve Them

Next.js is one of the most popular frameworks for React-based development due to its powerful features like server-side rendering (SSR), static site generation (SSG), and dynamic routing. However, like any complex framework, developers may encounter a range of challenges. In this post, we’ll cover some of the most common issues faced by Next.js developers and provide solutions and best practices to overcome them.1. Slow Build TimesOne of the most common issues when working with Next.js is slow build times, especially as your application grows.Why it happens:Next.js relies on the file system for routing. If you have a large number of pages, it can take time for Next.js to process them.If you’re using a lot of images, scripts, or other assets, these can also increase build time.How to fix it:Use Incremental Static Regeneration (ISR): This allows you to regenerate static content on-demand rather than at build time, which can significantly reduce the time spent building your site.Optimize images: Use the Next.js Image component and configure it for optimal performance.Consider dynamic imports: Split your code into smaller chunks with dynamic imports to improve load times and reduce the initial bundle size.const LazyComponent = dynamic(() => import('../components/LazyComponent'), { ssr: false, // disable SSR for the component if not needed }); 2. Client-Side Navigation Issue with Link ComponentThe Next.js Link component is designed to optimize client-side navigation. However, developers sometimes face issues where pages are not preloaded correctly or links don’t function as expected.Why it happens:Missing or incorrect usage of the href attribute.Using dynamic routes with incorrect parameter values can cause issues when navigating.How to fix it:Always ensure that the href is correctly defined. If using dynamic routes, ensure that the URL matches the expected pattern.Preload pages using the next/link prefetch feature, which can improve navigation speeds.<Link href="/about"> <a>About Us</a> </Link> 3. Image Optimization IssuesNext.js comes with built-in image optimization via the next/image component, but sometimes images don’t load as expected or appear blurry.Why it happens:Incorrect configuration of the Next.js Image component.The src attribute may not point to a valid image or a properly configured CDN.How to fix it:Always use the Next.js Image component for better optimization and ensure it has width and height defined.Ensure your images are hosted properly, and consider using a CDN for faster delivery.import Image from 'next/image'; <Image src="/path-to-image.jpg" alt="Description" width={500} height={500} /> 4. Server-Side Rendering (SSR) IssuesServer-side rendering (SSR) allows your pages to be rendered on the server before being sent to the browser. However, developers often encounter issues where the page is rendered incorrectly or errors arise due to asynchronous data fetching.Why it happens:SSR relies heavily on data-fetching methods like getServerSideProps, and misconfigurations in these methods can cause issues.Mixing client-side logic in server-side code can break the application.How to fix it:Ensure that you are using getServerSideProps or getInitialProps correctly. Avoid using client-side hooks (like useEffect) that modify state on the initial render.Be mindful of how your data is fetched—ensure the server has access to the data needed to render the page.export async function getServerSideProps() { const res = await fetch('https://api.example.com/data'); const data = await res.json(); return { props: { data } }; } 5. Routing Problems with Dynamic RoutesDynamic routes are one of Next.js’s most powerful features, but they can sometimes lead to confusion or errors if the parameters are not handled correctly.Why it happens:Incorrect file structure in the /pages directory can break dynamic routing.Failure to pass the correct query parameters when navigating to a dynamic route.How to fix it:Ensure your dynamic route files are named correctly. Next.js uses the file system to map routes, so file names with square brackets ([param]) are crucial.For example:/pages/posts/[id].js // This corresponds to /posts/:id route 6. API Routes Not Working ProperlyAPI routes are a great feature in Next.js, allowing you to build serverless API endpoints right in your Next.js app. However, developers sometimes run into issues with their API routes not responding as expected.Why it happens:Incorrect setup in the pages/api directory.Missing CORS configuration or incorrect HTTP methods.How to fix it:Ensure that the API routes are located in the pages/api directory, and double-check the HTTP method (GET, POST, etc.) used in the request.If you are accessing the API from the client, ensure that the URL is correctly constructed.// Example of an API route in Next.js export default async function handler(req, res) { if (req.method === 'GET') { const data = await fetch('https://api.example.com/data'); const result = await data.json(); res.status(200).json(result); } else { res.status(405).end(); // Method Not Allowed } } 7. Deployment IssuesNext.js apps are commonly deployed to platforms like Vercel, Netlify, or custom servers. Sometimes, deployment can cause issues like missing environment variables or incorrect builds.Why it happens:Misconfigured environment variables or missing configurations for production.Incorrect build settings for platforms like Vercel or Netlify.How to fix it:Ensure that all environment variables are set up correctly in the deployment platform’s settings.Double-check the next.config.js file to make sure production-specific settings are included.# In the deployment platform NEXT_PUBLIC_API_URL=https://api.example.com 8. Custom 404 Page Not ShowingNext.js allows you to create custom 404 pages, but sometimes developers find that their custom page is not showing up when a user navigates to a nonexistent route.Why it happens:Missing or incorrect setup of the pages/404.js file.How to fix it:Make sure you have a file named 404.js inside the pages directory and that it’s properly formatted.// pages/404.js export default function Custom404() { return <h1>404 - Page Not Found</h1>; } ConclusionNext.js offers incredible flexibility and features, but like any complex framework, it comes with its own set of challenges. By understanding common problems and implementing best practices, you can ensure your app is performant, scalable, and SEO-friendly.Remember to keep an eye on build times, optimize your images, write efficient API routes, and pay attention to routing and deployment issues. By doing so, you’ll be able to create high-quality applications that stand out in search engine results and deliver a great user experience.
