When creating web apps that work offline and can be installed.

Service Worker

self.addEventListener('install', e => {
  e.waitUntil(caches.open('v1').then(c => c.addAll(['/'])));
});

self.addEventListener('fetch', e => {
  e.respondWith(caches.match(e.request).then(r => r || fetch(e.request)));
});
