React State Management Simplified with React Query

You don’t need Redux for most React apps 👇 After working on multiple production systems, here’s what I’ve observed: Redux used for everything → Even simple UI state → Fix: Keep local state local (useState/useReducer) Server state in Redux → Manual caching, complex logic → Fix: Use React Query for API data Boilerplate overload → Actions, reducers, selectors everywhere → Fix: Use simpler patterns when possible Over-engineering early → Small app, big architecture → Fix: Scale architecture with app size Debugging becomes harder → Too many moving parts → Fix: Reduce unnecessary abstraction Redux is powerful. But power ≠ necessity. In many apps I’ve worked on: → Removing Redux simplified everything → Reduced bugs → Improved developer experience Senior engineers don’t ask: “Which library is best?” They ask: 👉 “Do I even need this?” What’s your take on Redux in 2026? #ReactJS #Redux #Frontend #JavaScript #SoftwareEngineering

Modern React apps often need to work with data that lives outside React: browser APIs, global stores, or third-party libraries. That’s exactly where useSyncExternalStore comes in. It’s a specialized hook that lets you safely subscribe to external data sources — while staying compatible with React’s concurrent rendering and avoiding bugs like inconsistent UI state (“tearing”). What is useSyncExternalStore? useSyncExternalStore connects your component to an external store and keeps it in sync. Instead of managing state inside React (useState, useEffect), you: - subscribe to changes - read the current snapshot - let React re-render when data updates const value = useSyncExternalStore(subscribe, getSnapshot); Where: - subscribe → tells React how to listen for changes - getSnapshot → returns current data - optional getServerSnapshot → for SSR React will re-render only when the external value actually changes. useSyncExternalStore is not a “daily hook” — but when you need it, nothing else fits as well. #react #frontend #webdev #javascript #reactjs #hooks

Most React developers are still thinking in a client-first way — and that’s becoming a problem. Server-first React is quietly changing how we build applications. The traditional approach: - Fetch in useEffect - Move data through APIs (JSON) - Render on the client This is no longer the default in modern React + Next.js. What’s changing: - Server Components handle data and rendering - Client Components are used only for interactivity - UI can be streamed directly from the server - Hydration is selective, not global Impact: - Less JavaScript sent to the browser - Reduced reliance on client-side state - Better performance by default - Simpler data flow (often without an extra API layer) A useful mental model: Server = data + structure Client = interaction This isn’t just a feature update - it’s a shift in architecture. If you’re still using useEffect primarily for data fetching, it may be time to rethink how your React apps are structured. #React #Frontend #Fullstack #JavaScript #WebDevelopment

Designing Reusable Behavior in React with Custom Hooks ⚛️ Before custom hooks, every single page in my React app looked like this: useState for data. useState for loading. useState for error. useEffect to fetch. Axios call. Error handling. Toast on success. Invalidate cache manually. Multiply that by 30+ pages. That's hundreds of lines of repeated logic. So I stopped copy-pasting and started building. → useCustomQuery One hook. Every GET and POST request in the entire app. TanStack Query under the hood — caching, gcTime, pagination, enabled flag — all configurable. Pass the URL, method, and queryKey. Get clean data back. Zero boilerplate in the component. → useCustomMutation One hook. Every create, update, and delete operation. Automatic query invalidation after success. Toast notification fires itself. Modal closes itself. Session expiry triggers logout via Axios interceptor. The component calls mutate() and forgets about the rest. → useDebounceSearch 15 lines. Proper setTimeout cleanup.Configurable timer. Every search input in 30+ pages uses this one hook. Saves hundreds of unnecessary API calls every day.Search changes → skip resets to 0 automatically. The component just renders. It has no idea how any of it works. The result? ✦ Components went from 80 lines to 20 ✦ New pages now take half the time to build ✦ Bugs are isolated — fix once, fixed everywhere ✦ The entire team uses complex logic without understanding every detail Custom hooks didn't just clean up my code. They changed how I think about building React apps. Are you still writing the same logic in every component — or have you made the switch to custom hooks? #ReactJS #Frontend #JavaScript #TypeScript #WebDevelopment #CleanCode #SoftwareEngineering #FrontendDevelopment #ReactHooks #TanStackQuery

🚀 React 19 Actions vs Redux — Is This the End of Global State as We Know It? For years, Redux has been the go-to solution for managing complex state in React applications. Predictable, powerful, and battle-tested. But now, React 19 Actions are entering the conversation—and they’re changing how we think about state management. Let’s break it down 👇 🔹 Redux: The Structured Powerhouse Redux shines when your application has: • Complex global state • Multiple data flows • A need for strict predictability With actions, reducers, and a single store, Redux gives you full control—but often at the cost of boilerplate and setup complexity. 🔹 React 19 Actions: The Built-In Simplicity React 19 introduces Actions that: • Simplify form handling and async state updates • Reduce the need for external libraries • Work seamlessly with server components Instead of wiring up reducers and dispatchers, you define async functions directly—cleaner, faster, and closer to native React patterns. ⚖️ So… Which One Should You Use? 👉 Choose Redux when: • Your app has deeply shared state across many components • You need middleware, dev tools, and advanced debugging • You’re working in large-scale enterprise environments 👉 Choose React 19 Actions when: • You want simplicity and speed • Your state is mostly local or tied to UI interactions • You’re leveraging modern React features like Server Components 💡 The Real Takeaway This isn’t about replacement—it’s about evolution. React is moving toward less dependency on external state libraries, but Redux still has a strong place in complex ecosystems. The smartest developers won’t pick sides—they’ll pick the right tool for the job. 💬 What’s your take? Are you sticking with Redux, or exploring React 19 Actions? #ReactJS #WebDevelopment #Frontend #JavaScript #Redux #SoftwareEngineering #TechTrends

If you ask an LLM to build a React app without providing enough context, it usually defaults to Next.js. Not because it’s the right tool for every job, but because it dominates the training data. I just published Part 2 of my series on React Frontend Architecture. I’m breaking down the trade-offs between classic SPA + API server, Full-stack frameworks, and Micro-frontends with BFFs. It’s about choosing a stack based on team size and maintainace cost, not just following the "AI default." 👇 Full tutorial here: https://lnkd.in/giwV9YYf #reactjs #softwarearchitecture #frontend

React re-render fixes React performance tips I learned the hard way over 8 years. Not from docs. From debugging slow UIs in production with real users waiting. Here are 5 things I wish someone told me on day one: 𝟭. Stop putting everything in one Context. I've seen apps where one global context holds auth, theme, user data, and cart state. Every update re-renders EVERYTHING. Split your contexts by update frequency. Auth rarely changes. Cart changes constantly. They shouldn't live together. 𝟮. useMemo and useCallback are not free. They have a cost — memory and comparison overhead. I've seen devs wrap every single function in useCallback "for performance." If the component isn't actually re-rendering unnecessarily, you're adding complexity for zero benefit. Profile first. Memoize second. 𝟯. Lazy load below the fold. On a banking platform, we had 40+ components loading on the dashboard. Users only saw 5 on first paint. We implemented React.lazy() + Suspense for everything below the fold. Page load dropped 35%. The trick: wrap lazy components in proper error boundaries, not just Suspense. 𝟰. Key prop abuse kills performance silently. Using array index as key in a list that reorders? React destroys and recreates every DOM node instead of reordering them. On a data grid with 500+ rows, this was the difference between a 200ms and 3-second re-render. Use stable, unique IDs. 𝟱. State colocation > state management libraries. Before reaching for Redux, ask: does this state need to be global? I've refactored apps where 60% of Redux state was only used by one component. Moving state closer to where it's used eliminated 45% of unnecessary re-renders in one project. The fastest React app isn't the one with the cleverest optimization. It's the one that avoids unnecessary work in the first place.

⚛️ Hey devs — are we overcomplicating React in 2026? I see many developers still adding heavy state management libraries in every project… but do we really need them anymore? Let’s be honest 👇 👉 With modern React: Server Components handle most data fetching Hooks manage local state efficiently Context is good enough for many global cases So why are we still doing this? ❌ Adding Redux for small apps ❌ Managing state that could live on the server ❌ Overengineering simple flows 💡 Here’s how I think about it now: Server → data & logic Client → interaction State → keep it minimal ⚡ Real talk: Most “state problems” are actually architecture mistakes. If your state is growing too much… maybe it shouldn’t be on the client at all. Curious — how are you managing state in your projects these days? #reactjs #nextjs #frontend #webdevelopment #statemanagement #javascript #softwareengineering #performance

Most devs think Server Components vs Client Components is about "where code runs." That's technically true. But it misses the point. After 3 years of building React apps, here's the mental model that finally clicked for me: 🖥️ Server Components = Your Data Layer Think of them as the backend of your frontend. They run on the server, can access databases directly, and ship ZERO JavaScript to the browser. Use them when: → Fetching data (no more useEffect waterfalls) → Reading env variables or secrets → Rendering static/heavy layouts 💻 Client Components = Your Interaction Layer These are classic React. They hydrate in the browser and handle ALL interactivity. Use them when: → You need state (useState, useReducer) → You need lifecycle hooks (useEffect) → You need event handlers (onClick, onChange) The mistake everyone makes? Thinking "Server = fast, Client = slow." Wrong. Server Components reduce your bundle. Client Components cache beautifully. The power is in MIXING them — not choosing one. Here's the real-world pattern I use: 📂 Server Component (layout + data fetching) └─ 💻 Client Component (interactive form) └─ 🖥️ Server Component (search results) Nest them. Compose them. Stop treating them like enemies. The mental shift: Server Components are not "better React." They're a different tool for a different job. Once you get this, Next.js App Router finally makes sense. #React #NextJS #WebDev #Frontend #ServerComponents
