An important piece of installing a service worker in your application is the ability to update it. Here a brief example of registering the service worker and then instructing it to check for an updated version.
if ('serviceWorker' in navigator) {
window.addEventListener('load', () => {
navigator.serviceWorker.register('/service-worker.js').then(registration => {
// Check for updates
registration.update();
console.log('SW registered and update called: ', registration);
}).catch(registrationError => {
console.log(registrationError);
});
});
}
