How can you detect internet connectivity in a React.js application?
This code snippet demonstrates how to detect the internet connection status using ReactJS. It sets up a functional component called App, which utilizes the useState and useEffect hooks from React.
The initial state of isOnline is determined by the window.navigator.onLine property, which indicates whether the user is currently connected to the internet.
The useEffect hook is used to add event listeners for the online and offline events triggered by the browser. When the user goes online or offline, the respective event handlers (handleOnline and handleOffline) update the isOnline state accordingly using the setIsOnline function.
To prevent memory leaks, the event listeners are removed when the component unmounts by returning a cleanup function from the useEffect hook.
Finally, the rendered JSX displays a message indicating whether the user is online or offline based on the isOnline state.
