How I Simplified API Integration in Next.js

Building Custom Hooks for Cleaner Code in React When React apps start growing, managing logic across multiple components can get messy. That’s where Custom Hooks come in — your secret weapon for writing cleaner, reusable, and more maintainable code. 🔹 What are Custom Hooks? Custom Hooks are simply JavaScript functions that use React hooks (like useState, useEffect, etc.) to share logic between components — without duplicating code. 🔹 Why Use Them? Promotes reusability of logic. Keeps components clean & focused on UI. Improves readability and maintainability 🔹 Example: useFetch Hook import { useState, useEffect } from "react"; function useFetch(url) {   const [data, setData] = useState(null);   const [loading, setLoading] = useState(true);   useEffect(() => {     fetch(url)       .then((res) => res.json())       .then((data) => {         setData(data);         setLoading(false);       });   }, [url]);   return { data, loading }; } Now, any component can easily use this logic: const { data, loading } = useFetch("https://lnkd.in/gVChxg-b"); Custom Hooks help you write DRY (Don’t Repeat Yourself) code and keep your components focused on rendering — not logic. #ReactJS #WebDevelopment #JavaScript #CleanCode #ReactHooks #FrontendDevelopment

🚀 Zod vs Joi vs Validator.js — Which One Should You Use? In modern web development, data validation is non-negotiable. Whether you're handling user input on the frontend or securing APIs on the backend — a solid validation library keeps your app safe and your data clean. Let’s quickly break down three popular libraries 👇 🧩 1️⃣ Zod Written in TypeScript — perfect type inference! Validation + schema definition in one place Excellent for frontend frameworks like React, Next.js, and tRPC Lightweight and developer-friendly ✅ Best for: TypeScript projects & full-stack apps using Next.js or tRPC ⚙️ 2️⃣ Joi Mature and battle-tested by the Node.js community Powerful schema syntax and great for complex backend logic Rich plugin ecosystem Slightly heavier and not TypeScript-first ✅ Best for: Backend (Node.js, Express, Hapi) applications 🧮 3️⃣ Validator.js Focused on string validation (emails, URLs, UUIDs, etc.) No schema system — you manually call functions Extremely lightweight ✅ Best for: Simple validations or when you only need quick field checks ⚔️ So which one wins? 💡 If you're building a TypeScript-based full-stack app → go with Zod. 💡 If your project is a backend API without TS → Joi fits perfectly. 💡 If you just need quick, simple field validation → Validator.js is all you need. 📣 My pick: Zod — it’s modern, TypeScript-friendly, and keeps your validation and types in perfect sync. What about you? Which validation library do you prefer — and why? 🤔 #WebDevelopment #JavaScript #TypeScript #NodeJS #React #Backend #Frontend #Zod #Joi #Validatorjs

𝐇𝐚𝐯𝐞 𝐲𝐨𝐮 𝐞𝐯𝐞𝐫 𝐜𝐥𝐢𝐜𝐤𝐞𝐝 𝐨𝐧 𝐚 𝐜𝐚𝐫𝐝 𝐢𝐧 𝐚 𝐑𝐞𝐚𝐜𝐭 𝐚𝐩𝐩 𝐚𝐧𝐝 𝐰𝐨𝐧𝐝𝐞𝐫𝐞𝐝 — “𝐡𝐨𝐰 𝐝𝐨𝐞𝐬 𝐢𝐭 𝐦𝐚𝐠𝐢𝐜𝐚𝐥𝐥𝐲 𝐨𝐩𝐞𝐧 𝐚 𝐝𝐞𝐭𝐚𝐢𝐥𝐞𝐝 𝐩𝐚𝐠𝐞 𝐟𝐨𝐫 𝐭𝐡𝐚𝐭 𝐞𝐱𝐚𝐜𝐭 𝐢𝐭𝐞𝐦?” Well… I just made that happen! 🚀 I recently built a Dynamic Detailed Page where every card from an API gets its own unique page — all using just one component Here’s the exciting part 👇 With this single line of code: 𝒄𝒐𝒏𝒔𝒕 { 𝒊𝒅 } = 𝒖𝒔𝒆𝑷𝒂𝒓𝒂𝒎𝒔(); I can now grab the ID directly from the URL and show that exact post’s data dynamically. No repeated components. No messy routes. Just clean, scalable React magic 🧩 What I used: - React Router (for dynamic routing) - React Query (for smooth API data fetching) - CSS (for polished UI & transitions) - Axios (for fetching individual post data) And yup — I also added a neat “Go Back” button and custom CSS animations to make the transition smooth Every click → new page → new data → same component #ReactJS #FrontendDevelopment #ReactRouter #ReactQuery #WebDev #JavaScript

⚛️ React 19 — What’s Actually New (and Useful) After playing around with React 19, it’s clear this release focuses less on adding shiny APIs and more on simplifying the full‑stack developer experience. Here’s what stands out 👇 1️⃣ Server Components – Real SSR without hacks You can now render async components directly on the server — no client bundles needed. Faster loads, better SEO. // Users.server.jsx export default async function Users() { const res = await fetch("https://lnkd.in/g2xx7ggw"); const users = await res.json(); return users.map(u => <p key={u.id}>{u.name}</p>); } 2️⃣ Actions API – Form handling made elegant Server and client code finally blend naturally. "use server"; export async function saveUser(data) { await db.user.create(data); return { success: true }; } "use client"; import { saveUser } from "./actions"; <form action={saveUser}><button>Save</button></form> 3️⃣ useOptimistic – Instant UI feedback for async ops Your UI stays snappy while waiting for responses. const [todos, addTodo] = useOptimistic([], (t, n) => [...t, n]); function handleAdd(name) { addTodo({ name, sending: true }); } 4️⃣ React Compiler – Goodbye, memo hell React 19’s experimental compiler optimizes components automatically, so you don’t need `useMemo`, `useCallback`, or `React.memo` spam anymore. 5️⃣ Ref as Prop – No more `forwardRef()` circus You can now pass refs directly between components, keeping your code modular and readable. Overall: React 19 feels like a maturity release — less mental overhead, smoother SSR, and smarter performance out of the box.

Your Browser Is Smarter Than You Think As frontend developers, we often rush to install libraries and frameworks. But sometimes, the real magic is already sitting there inside your browser. I’m talking about Web APIs . The built-in tools that quietly power most of what we do on the web. From updating the DOM to storing user preferences, recording audio, or fetching data , the Web APIs do it all. 1. DOM & CSSOM APIs handle how things look and behave. 2. Fetch API deals with data communication. 3. Storage APIs (LocalStorage, SessionStorage, IndexedDB) remember what matters to users. 4. Geolocation, Clipboard, Notifications, and Speech APIs bring real-world features to life. What’s beautiful is that these aren’t third-party hacks , they’re native capabilities, built right into the browser. Sometimes, the smartest thing a developer can do is pause before importing and ask, “Can the browser already do this for me?” #WebDevelopment #Frontend #JavaScript #WebAPI #BrowserAPIs #FrontendDevelopment #Coding #LearnInPublic

𝗛𝗼𝘄 𝗜 𝗦𝘁𝗼𝗽𝗽𝗲𝗱 𝗠𝘆 𝗥𝗲𝗮𝗰𝘁 𝗔𝗽𝗽 𝗳𝗿𝗼𝗺 𝗦𝗹𝗼𝘄𝗶𝗻𝗴 𝗗𝗼𝘄𝗻 A few months ago, one of my React components started lagging. Every click triggered re-renders — and the UI felt painfully sluggish. I assumed it was my API or data fetching... but nope. The real issue? My component was recalculating the same logic on every render. That’s when I discovered the magic of 𝘂𝘀𝗲𝗠𝗲𝗺𝗼() and honestly, it felt like flipping a performance switch. 𝗤𝘂𝗶𝗰𝗸 𝗦𝘆𝗻𝘁𝗮𝘅: const memo = useMemo(() => expensiveCalculation(a, b), [a, b]); 𝗪𝗵𝗮𝘁 𝗜 𝗟𝗲𝗮𝗿𝗻𝗲𝗱: 𝘂𝘀𝗲𝗠𝗲𝗺𝗼() basically tells React: “Hey, remember this calculation unless something changes.” That one line helped my app skip unnecessary work and become noticeably smoother. 𝗞𝗲𝘆 𝗧𝗮𝗸𝗲𝗮𝘄𝗮𝘆𝘀: Perfect for heavy computations — sorting, filtering, mapping large data Helps avoid unnecessary re-renders. But don’t overuse it — optimization ≠ default 𝗙𝗶𝗻𝗮𝗹 𝗧𝗵𝗼𝘂𝗴𝗵𝘁: 𝘂𝘀𝗲𝗠𝗲𝗺𝗼() won’t magically speed up your app but it will keep it from getting slower. Use it smartly, not everywhere. Have you used 𝘂𝘀𝗲𝗠𝗲𝗺𝗼() in your projects? What kind of performance gains did you notice?

🧩 Pure Functions — The Unsung Hero of Clean React Code After 4 years in web development, one lesson has stuck with me: 👉 Predictable code is maintainable code. Early in my React journey, I often faced weird UI bugs — the kind that appeared only sometimes. I’d pass the same props, but the component behaved differently. The issue? My components weren’t pure. 💢 💡 A pure function is beautifully simple: ✅ Returns the same output for the same inputs ✅ Has zero side effects (doesn’t modify anything outside its scope) This concept completely changed how I write React components. ⚛️ In React, pure components behave like mathematical functions — for the same props, they’ll always produce the same UI. No hidden state. No unexpected behavior. Just consistency. 💻 Example — A Pure Function Component: const Greeting = ({ name }) => { return <h1>Hello, {name}!</h1>; }; No matter how many times it renders, if name = "Shweta", you’ll always get the same output: Hello, Shweta! That’s the essence of purity — predictable, testable, and optimized for performance. 🧠 Takeaway: Pure functions may sound like a small concept, but they’re the foundation of scalable, maintainable React applications. Write components that React can trust. #ReactJS #JavaScript #WebDevelopment #CleanCode #HappyCoding #FrontendDevelopment #FullStackDeveloper #ProgrammingTips ✅ Source: https://lnkd.in/dxxTJd85 ✏️ Image illustrated by RL Nabors

🚨 Handling API Errors Gracefully in React APIs can be unpredictable, from network drops to 500 errors, but your UI doesn't have to suffer. Implementing a reliable pattern ensures your application responds gracefully even when errors occur. Here's a simple and effective approach: ✅ Maintain clear loading, success, and error states ✅ Provide a retry button for seamless user interaction ✅ Display user-friendly messages instead of technical stack traces Example pattern: ```javascript import { useState, useEffect, useCallback } from "react"; import axios from "axios"; export default function useApi(url, deps = []) { const [data, setData] = useState(null); const [loading, setLoading] = useState(true); const [error, setError] = useState(null); const [trigger, setTrigger] = useState(0); const refetch = useCallback(() => setTrigger(t => t + 1), []); useEffect(() => { let mounted = true; setLoading(true); setError(null); axios.get(url) .then(res => mounted && setData(res.data)) .catch(err => mounted && setError(err.message)) .finally(() => mounted && setLoading(false)); return () => { mounted = false; }; }, [url, trigger, ...deps]); return { data, loading, error, refetch }; } ``` 💡 Why it works: - Ensures stable component behavior with predictable UI states - Enhances user experience by providing clear feedback - Facilitates recovery and retry without full page reloads - Aligns with industry standards like React Query for error handling It may seem like a minor detail, but this approach adds a layer of reliability and professionalism to your application. #ReactJS #Frontend #WebDevelopment #MERNStack #JavaScript #ErrorHandling #CodingTips

Next.js 16 — The Web Just Got an Upgrade! Every once in a while, a framework doesn’t just update — it evolves.
