I ditched useEffect for data fetching. Here's why I'm not going back. For the longest time, I thought useEffect was the "React way" to fetch data. Loading state? Add a useState. Error handling? Another useState. Race conditions? Then I discovered React Query — and I felt like I'd been writing in hard mode the whole time. Look at the difference: ❌ Before — 15+ lines just to fetch a user. Manual cleanup. Race condition workarounds. Error & loading states all over the place. ✅ After — useQuery. Three lines. Done. Here's what I gained immediately: ⚡ Automatic caching & deduplication — two components needing the same data? One network call. Not two. 🔁 Background refetching — data stays fresh without me writing a single timer or polling loop. 🛡️ Race conditions — handled — no more "old response overwriting new one" bugs. React Query deals with it out of the box. 📉 ~60% less boilerplate — I removed hundreds of lines of state management code across our dashboard in one refactor. The mental shift that helped me: useEffect is for syncing with external systems. It was never meant to be a data fetching tool. React Query is purpose-built for server state — and it shows. If you're still reaching for useEffect every time you need an API call, give React Query one week. You won't look back. What was your turning point with server-state management?

Are you still using useEffect for Data Fetching in 2026? 🛑 React development evolve ho chuki hai, lekin aaj bhi kaafi developers purane tarike se data fetch karte hain. Let’s break down why useQuery (TanStack Query) wins: ❌ The "Old" Way (useEffect): Boilerplate: Loading, Error aur Data ke liye 3 alag states banani padti hain. No Caching: Har baar component mount hone par network request jati hai. Race Conditions: Multiple requests manage karna mushkil hota hai. ✅ The "Smart" Way (TanStack Query): Built-in States: isLoading, isError, aur data ready-to-use milte hain. Smart Caching: Data memory mein save rehta hai, bar-bar fetch karne ki zarurat nahi. Auto-Retry: Agar network fail ho jaye, to ye khud retry karta hai. Clean code likhna sirf preference nahi, performance ki demand hai! 🚀 #ReactJS #WebDevelopment #Frontend #TanStackQuery #CleanCode #JavaScript #WebGyaan

⚡ Stop writing useEffect for data fetching in React. We've all written this at least once: useEffect(() => { setLoading(true); fetch('/api/users') .then(res => res.json()) .then(data => setData(data)) .catch(err => setError(err)) .finally(() => setLoading(false)); }, []); It works. But you're manually handling things React Query does for free. Here's what your useEffect approach is missing: ❌ No caching — refetches every single mount ❌ No background refetching ❌ No automatic retries on failure ❌ No deduplication of requests ❌ Boilerplate loading/error state every time ✅ The fix? React Query. const { data, isLoading, error } = useQuery({ queryKey: ['users'], queryFn: () => fetch('/api/users').then(r => r.json()) }); That's it. 4 lines replace 15. What you get out of the box: ✅ Smart caching — won't refetch if data is fresh ✅ Background sync — keeps data up to date silently ✅ Auto retry on network failure ✅ Built-in loading & error states ✅ Request deduplication useEffect is great — but it was never meant to be a data fetching tool. Work smarter, not harder. 🚀 #React #ReactQuery #JavaScript #Frontend #WebDevelopment #Performance #Programming

Tired of manually copy-pasting data? Let’s automate it. Over my 8 years of building backend systems and scrapers, I've found that turning the static web into actionable data is an absolute superpower. In this video, I break down how to build a custom, multi-page web scraper from scratch using Node.js. We scrape Hacker News job listings, filter for specific roles, and automatically output a clean, timestamped CSV. The Stack & Process: Axios: Fetching the raw HTML. Cheerio: Parsing the DOM to extract titles, links, and dates. Recursion: Automatically handling pagination to jump from page to page. CSV/Moment: Generating the final structured dataset. Cheerio is lightning-fast for static HTML, but next time, we’ll step up to full browser automation for complex client-side rendered sites. What is the toughest site you've ever had to scrape? Let me know below. 👇 #NodeJS #WebScraping #BackendEngineering #Automation #JavaScript

If you're copying and pasting the same useState + useEffect logic across multiple components, you need a custom hook. Example — a reusable data fetching hook: ```js function useFetch(url) { const [data, setData] = useState(null); const [loading, setLoading] = useState(true); const [error, setError] = useState(null); useEffect(() => { let cancelled = false; fetch(url) .then(r => r.json()) .then(data => { if (!cancelled) setData(data); }) .catch(err => { if (!cancelled) setError(err); }) .finally(() => { if (!cancelled) setLoading(false); }); return () => { cancelled = true; }; }, [url]); return { data, loading, error }; } // Usage — clean and consistent everywhere const { data: users, loading } = useFetch('/api/users'); const { data: products } = useFetch('/api/products'); ``` Custom hooks keep components focused on rendering and move logic to where it can be tested and reused. #ReactJS #JavaScript #Frontend #WebDevelopment

This Week in Rails: A new `rails query` command lands: run read-only ActiveRecord queries from the command line and get structured JSON output with columns, rows, pagination metadata, query time, and generated SQL. Subcommands include `query schema`, `query models`, and `query explain`. Also: static CSS and HTML files now include `charset=utf-8` in Content-Type, new Rails apps get a PWA offline fallback page, and ParameterFilter gains O(1) hash lookup for exact-match regexp filters. Read all that and more in this week's newsletter: https://lnkd.in/dWycC_Ps This week there were 15 contributors to Rails. Thank you to all those whose PRs were highlighted this week: Lewis Buckley Mike Dalessio Juan Vásquez Gabriel Quaresma Dima Fatko Alex Watt Paul McMahon Check out the full list of the week's contributors at: https://lnkd.in/dZvYXQPs

This week has been exceptionally productive. While preparing a talk on Progressive Web Apps (PWAs) for Rails, I contributed by adding the offline page for the PWA scaffold provided by Rails. It is remarkable how all these elements have come together: Rails -> Work -> Talk 🔁, in a continuous cycle.
