🚀 React Tip: Junior vs Pro Developers in useEffect ⚡ When working with React hooks — especially useEffect — even small mistakes can cause memory leaks or unnecessary API calls. 💡 Example: Many junior developers fetch data inside useEffect without handling component unmounts. This can result in updating state after the component is gone — a common source of bugs. A pro developer, however, prevents this issue by using an AbortController to cancel any pending requests when the component unmounts. 🧠 Junior vs Pro ❌ Junior: Fetches data directly inside useEffect ✅ Pro: Uses AbortController to safely abort fetch requests on cleanup By integrating AbortController, you ensure that no state updates happen after unmounting — keeping your app stable, efficient, and clean. ✨ Pro Tip: Always clean up your side effects in useEffect. This small step can make a huge difference in performance and reliability. 🛠️ Tech Stack: React.js | JavaScript | Frontend Optimization #ReactJS #ReactTips #ReactDeveloper #ReactHooks #useEffect #JavaScript #FrontendDevelopment #WebDevelopment #CleanCode #CodeQuality #microsoft
Pro max tip : Use reactQuery with signal injection insted regular fetch inside effect hook 🙃 Trust me, it’s life changing
what about tanstack query
Not an expert in React, but sounds like there should be a library doing this behind the scenes. For instance in Angular, if you are doing it the "Angularish" way (async pipe or signals), the component destroy will unsubscribe from the async task and abort the request (using the same AbortController behind the scenes).
