React-BeforeUnload and React-Native

React-BeforeUnload and React-Native are two popular libraries for handling the beforeunload event in React applications. The beforeunload event is triggered when the user tries to leave a page, and can be used to prompt the user with a confirmation dialog before they leave.

React-BeforeUnload

React-BeforeUnload is a library that provides a component for handling the beforeunload event in React applications. The component, called BeforeUnload, can be used to wrap any part of your application that you want to monitor for the beforeunload event.

To use React-BeforeUnload, first install it using npm:

npm install react-beforeunload

Next, import the BeforeUnload component:

import { BeforeUnload } from 'react-beforeunload';

Then, wrap your component with the BeforeUnload component and provide a callback function:

<BeforeUnload onBeforeunload={() => 'Are you sure you want to leave?'} />

In this example, a confirmation dialog will be displayed when the user tries to leave the page.

React-Native

React-Native is a library for building mobile applications using React. It provides a component called Linking that can be used to handle the beforeunload event in a similar way to React-BeforeUnload.

To use Linking, first import it:

import { Linking } from 'react-native';

Then, register a handler for the beforeunload event:

Linking.addEventListener('beforeunload', () => 'Are you sure you want to leave?');

In this example, a confirmation dialog will be displayed when the user tries to leave the app.

Conclusion

React-BeforeUnload and React-Native provide two different ways to handle the beforeunload event in React applications. React-BeforeUnload is useful for web applications, while React-Native is useful for mobile applications. Both libraries are easy to use and provide a simple way to prompt the user before they leave the current page or app.
