How to detect when redirect happens in react.js?

You can detect when a redirect happens in React.js by listening to the change in the browser's history using the useEffect hook provided by React. Here's an example of how you can accomplish this:

import { useEffect } from 'react';
import { useHistory } from 'react-router-dom';

const MyComponent = () => {
  const history = useHistory();
  
  useEffect(() => {
    const unlisten = history.listen((location, action) => {
      // Check if the action is a redirect
      if (action === 'REPLACE') {
        console.log('Redirect happened');
      }
    });
    
    return () => {
      unlisten();
    };
  }, []);

  return (
    // Your component JSX
  );
};

export default MyComponent;

In this example, we're using the useHistory hook from react-router-dom to access the history object and listen to location changes. We then use the useEffect hook to listen for changes in the history object and check if the action is a redirect by comparing it to the string 'REPLACE'.

When a redirect happens, the console will log 'Redirect happened'. You can also perform any other logic or state management based on the redirect in the if block.
