🔸 TLDR 🧾
▪️ A clean “starter” useFetch: great for small UI pieces and learning — but production apps need loading/error/cancel/cache. ✅⚠️
🔸 THE TINY HOOK (CODE) 🧩
🔸 WHAT IT DOES ✅
▪️ Fetches JSON whenever url changes 🔁
▪️ Stores the response in React state (data) 📦
▪️ Returns data so components stay clean 🧼
🔸 WHEN THIS IS PERFECT 🎯
▪️ Quick prototypes / demos / coding katas 🧪
▪️ Small widgets: dashboards, lists, simple panels 📊
▪️ Learning useEffect + async flows in React 🧠
🔸 THE GOTCHAS (WHY IT’S “SIMPLE”) ⚠️
▪️ No loading state ⏳
▪️ No error handling ❌
▪️ No request cancellation (can set state after unmount) 🧨
▪️ No caching / dedup / retries 🧱
▪️ Assumes “JSON always works” (no r.ok check) 🤞
🔸 HOW TO LEVEL IT UP (STILL LIGHTWEIGHT) 🔧
▪️ Return { data, loading, error } 🧰
▪️ Check response.ok and throw on errors 🚫
▪️ Use AbortController to cancel on unmount / url change 🛑
▪️ Consider a real data-fetching lib for production (React Query / SWR) 🏗️
🔸 TAKEAWAYS 🧠
▪️ Minimal hooks teach the pattern fast 🏎️
▪️ Production needs resilience (errors, cancellation, caching) 🛡️
▪️ Keep it simple… until your UX depends on it 😉
