Examples

You can use the notificationclick event in an addEventListener method:

self.addEventListener('notificationclick', function(event) {
  console.log('On notification click: ', event.notification.tag);
  event.notification.close();

  // This looks to see if the current is already open and
  // focuses if it is
  event.waitUntil(clients.matchAll({
    type: "window"
  }).then(function(clientList) {
    for (var i = 0; i < clientList.length; i++) {
      var client = clientList[i];
      if (client.url == '/' && 'focus' in client)
        return client.focus();
    }
    if (clients.openWindow)
      return clients.openWindow('/');
  }));
});

Or use the onnotificationclick event handler property:

self.onnotificationclick = function(event) {
  console.log('On notification click: ', event.notification.tag);
  event.notification.close();

  // This looks to see if the current is already open and
  // focuses if it is
  event.waitUntil(clients.matchAll({
    type: "window"
  }).then(function(clientList) {
    for (var i = 0; i < clientList.length; i++) {
      var client = clientList[i];
      if (client.url == '/' && 'focus' in client)
        return client.focus();
    }
    if (clients.openWindow)
      return clients.openWindow('/');
  }));
};

You can handle event actions using event.action within a notificationclick event handler:

navigator.serviceWorker.register('sw.js');
Notification.requestPermission(function(result) {
  if (result === 'granted') {
    navigator.serviceWorker.ready.then(function(registration) {
      // Show a notification that includes an action titled Archive.
      registration.showNotification('New mail from Alice',
        {
          actions: [
            {
              action: 'archive',
              title: 'Archive'
            }
          ]
        }
      )
    });
  }
});

self.addEventListener('notificationclick', function(event) {
  event.notification.close();
  if (event.action === 'archive') {
    // User selected the Archive action.
    archiveEmail();
  } else {
    // User selected (e.g., clicked in) the main body of notification.
    clients.openWindow('/inbox');
  }
}, false);
