Programmatically update service worker if update() is not available

Question

How can I programmatically update service worker since ServiceWorkerRegistration.update() has not been implemented in Chrome yet? Is there an alternative?

Answer 1

I assume you got this by now but I think you want serviceWorker.skipWaiting()

Answer 2

From the spec.

if ('serviceWorker' in navigator) {
  navigator.serviceWorker.register('/sw-test/sw.js', {scope: 'sw-test'}).then(function(registration) {
    // registration worked
    console.log('Registration succeeded.');
    button.onclick = function() {
      registration.update();
    }
  }).catch(function(error) {
    // registration failed
    console.log('Registration failed with ' + error);
  });
};
