  57. Initiatives to address this New web features
  58. Offline access => Service Workers Service Workers
  59. It's a JavaScript Worker, so it can't access the DOM directly. Instead responds to postMessages Service worker is a programmable network proxy It will be terminated when not in use, and restarted when it's next needed Makes extensive use of Promises Service Workers
  60. HTTPS is Needed Service Workers
  61. Register and Installing a Service Worker if ('serviceWorker' in navigator) {
 navigator.serviceWorker.register('/sw.js').then(function(registration) {
 // Registration was successful
 console.log('ServiceWorker registration successful with scope: ', registration.scope);
 }).catch(function(err) {
 // registration failed :(
 console.log('ServiceWorker registration failed: ', err);
 });
 }
  62. chrome://inspect/#service-workers chrome://serviceworker-internals/ Service Workers
  63. // The files we want to cache
 var urlsToCache = [
 '/',
 '/styles/main.css',
 '/script/main.js'
 ];
 
 // Set the callback for the install step
 self.addEventListener('install', function(event) {
 // Perform install steps
 }); Installing a Service Worker
  64. Inside our install callback: 1. Open a cache 2. Cache our files 3. Confirm whether all the required assets are cached or not Installing a Service Worker
  65. Install callback var CACHE_NAME = 'my-site-cache-v1';
 var urlsToCache = [
 '/',
 '/styles/main.css',
 '/script/main.js'
 ];
 
 self.addEventListener('install', function(event) {
 // Perform install steps
 event.waitUntil(
 caches.open(CACHE_NAME)
 .then(function(cache) {
 console.log('Opened cache');
 return cache.addAll(urlsToCache);
 })
 );
 });
  66. self.addEventListener('fetch', function(event) {
 event.respondWith(
 caches.match(event.request)
 .then(function(response) {
 // Cache hit - return response
 if (response) {
 return response;
 }
 
 return fetch(event.request);
 }
 )
 );
 }); Caching and Returning Requests
  67. Updating a Service Worker
  68. 1. Update your service worker JavaScript file. 2. Your new service worker will be started and the install event will be fired. 3. New Service Worker will enter a "waiting" state 4. When open pages are closed, the old Service Worker will be killed - new service worker will take control. 5. Once new Service Worker takes control, its activate event will be fired. Updating a Service Worker
  69. Instant Loading Web Apps with An Application Shell Architecture Application Shell

  72. Background Sync Chrome Dev for Android or Chrome Canary for desktop chrome://flags/#enable-experimental-web-platform-features Restart the browser
  73. Notifications => Push notifications
  74. Push notifications
  75. // Are Notifications supported in the service worker? 
 if (!('showNotification' in ServiceWorkerRegistration.prototype)) { 
 console.warn('Notifications aren't supported.'); 
 return; 
 } Push notifications
  76. // Check the current Notification permission. 
 // If its denied, it's a permanent block until the 
 // user changes the permission 
 if (Notification.permission === 'denied') { 
 console.warn('The user has blocked notifications.'); 
 return; 
 } Push notifications
  77. // Check if push messaging is supported 
 if (!('PushManager' in window)) { 
 console.warn('Push messaging isn't supported.'); 
 return; 
 } Push notifications
  78. // We need the service worker registration to check for a subscription 
 navigator.serviceWorker.ready.then(function(serviceWorkerRegistration) { 
 // Do we already have a push message subscription? 
 serviceWorkerRegistration.pushManager.getSubscription() 
 .then(function(subscription) { 
 // Enable any UI which subscribes / unsubscribes from 
 // push messages. 
 var pushButton = document.querySelector('.js-push-button'); 
 pushButton.disabled = false;
 
 if (!subscription) { 
 // We aren't subscribed to push, so set UI 
 // to allow the user to enable push 
 return; 
 }
 
 // Keep your server in sync with the latest subscriptionId
 sendSubscriptionToServer(subscription);
 
 // Set your UI to show they have subscribed for 
 // push messages 
 pushButton.textContent = 'Disable Push Messages'; 
 isPushEnabled = true; 
 }) 
 .catch(function(err) { 
 console.warn('Error during getSubscription()', err); 
 }); 
 }); Push notifications
  79. {

  80. Add to Homescreen
  81. Cache management & whitelistsApp Install Banners
  82. App Install Banners prerequisites You have a web app manifest file You have a service worker registered on your site. We recommend a simple custom offline page service worker Your site is served over HTTPS (you need a service worker after all) The user has visited your site twice over two separate days during the course of two weeks.
  83. All this leads to progressive apps
  84. Progressive Apps These apps aren’t packaged and deployed through stores, they’re just websites that took all the right vitamins. They keep the web’s ask-when-you-need-it permission model and add in new capabilities like being top-level in your task switcher, on your home screen, and in your notification tray - Alex Russell
