Have you ever wanted to notify users when they lose internet connectivity in your React app? Today we build AppShell component together that monitors the browser's online/offline status and shows a user friendly message when the user goes offline. Why? Realtime apps (like chat, stock tickers, etc.) depend on live connectivity. Offline-friendly experiences build trust and reliability. It's surprisingly easy to implement. The code Lets Wrap the entire app (or any major layout component) with AppShell: Behind the Scenes. -** navigator.onLine:** Detects the initial connection status. -** window.addEventListener("online"/"offline"):** Reacts to changes in network status. useEffect: Registers and cleans up event listeners when the component mounts/unmounts. Let me know how you're handling offline states in your apps :)
