I'm registering my workbox service worker as follows:

<script>
        if ('serviceWorker' in navigator) {
            window.addEventListener('load', () => {
                navigator.serviceWorker.register('/sw.js');
            });
        }
    </script>

The service worker is successfully registered but when I update the application the application is not updating until I clear all cache manually and restart chrome. How do I register a service worker in a way that it will self-update everytime I update the app?
