6. What is a PWA? RELIABLE
7. What is a PWA? RELIABLE FAST
8. What is a PWA? RELIABLE FAST ENGAGING
9. Demo
11. Service Workers
12. Have you heard of a Web Worker?
13. ServiceWorker != WebWorker
15. if('serviceWorker' in navigator) { navigator.serviceWorker.register('/offline.js', { scope: '/' }) .then(function(registration) { console.log('Service Worker Registered'); }); navigator.serviceWorker.ready .then(function(registration) { console.log('Service Worker Ready'); }); } SERVICE WORKER
16. INSTALL const CACHE_NAME = ‘DevUp’ // Version 0.6.5 self.addEventListener('install', e => { console.log('installing service worker!!') const timeStamp = Date.now(); e.waitUntil( caches.open(CACHE_NAME).then(cache => { return cache.addAll([ `/`, `/index.html`, `/json/data.json`, `/static/js/bundle.js` ]) .then(() => self.skipWaiting()); }) ); });
17. INSTALL const CACHE_NAME = ‘DevUp’ // Version 0.6.5 self.addEventListener('install', e => { console.log('installing service worker!!') const timeStamp = Date.now(); e.waitUntil( caches.open(CACHE_NAME).then(cache => { return cache.addAll([ `/`, `/index.html`, `/json/data.json`, `/static/js/bundle.js` ]) .then(() => self.skipWaiting()); }) ); });
18. INSTALL const CACHE_NAME = ‘DevUp' // Version 0.6.5 self.addEventListener('install', e => { console.log('installing service worker!!') const timeStamp = Date.now(); e.waitUntil( caches.open(CACHE_NAME).then(cache => { return cache.addAll([ `/`, `/index.html`, `/json/data.json`, `/static/js/bundle.js` ]) .then(() => self.skipWaiting()); }) ); });
19. ACTIVATE self.addEventListener('activate', event => { console.log('activating service worker'); event.waitUntil(self.clients.claim()); });
20. FETCH self.addEventListener('fetch', function(event) {…})
21. FETCH event.respondWith( caches.match(event.request) .then(function(response) { // Cache hit - return response if (response) { return response; } var fetchRequest = event.request.clone(); return fetch(fetchRequest).then( function(response) { // Check if we received a valid response if(!response || response.status !== 200 || response.type !== 'basic'){ return response; } var responseToCache = response.clone(); caches.open(CACHE_NAME)
22. FETCH event.respondWith( caches.match(event.request) .then(function(response) { // Cache hit - return response if (response) { return response; } var fetchRequest = event.request.clone(); return fetch(fetchRequest).then( function(response) { // Check if we received a valid response if(!response || response.status !== 200 || response.type !== 'basic'){ return response; } var responseToCache = response.clone(); caches.open(CACHE_NAME)
23. FETCH event.respondWith( caches.match(event.request) .then(function(response) { // Cache hit - return response if (response) { return response; } var fetchRequest = event.request.clone(); return fetch(fetchRequest).then( function(response) { // Check if we received a valid response if(!response || response.status !== 200 || response.type !== 'basic'){ return response; } var responseToCache = response.clone(); caches.open(CACHE_NAME)
24. event.respondWith( caches.match(event.request) .then(function(response) { // Cache hit - return response if (response) { return response; } var fetchRequest = event.request.clone(); return fetch(fetchRequest).then( function(response) { // Check if we received a valid response if(!response || response.status !== 200 || response.type !== 'basic'){ return response; } var responseToCache = response.clone(); caches.open(CACHE_NAME) FETCH
25. } var fetchRequest = event.request.clone(); return fetch(fetchRequest).then( function(response) { // Check if we received a valid response if(!response || response.status !== 200 || response.type !== 'basic'){ return response; } var responseToCache = response.clone(); caches.open(CACHE_NAME) .then(function(cache) { cache.put(event.request, responseToCache); }); return response; } ); }) ); FETCH
26. } var fetchRequest = event.request.clone(); return fetch(fetchRequest).then( function(response) { // Check if we received a valid response if(!response || response.status !== 200 || response.type !== 'basic'){ return response; } var responseToCache = response.clone(); caches.open(CACHE_NAME) .then(function(cache) { cache.put(event.request, responseToCache); }); return response; } ); }) ); FETCH
27. } var fetchRequest = event.request.clone(); return fetch(fetchRequest).then( function(response) { // Check if we received a valid response if(!response || response.status !== 200 || response.type !== 'basic'){ return response; } var responseToCache = response.clone(); caches.open(CACHE_NAME) .then(function(cache) { cache.put(event.request, responseToCache); }); return response; } ); }) ); FETCH
28. } var fetchRequest = event.request.clone(); return fetch(fetchRequest).then( function(response) { // Check if we received a valid response if(!response || response.status !== 200 || response.type !== 'basic'){ return response; } var responseToCache = response.clone(); caches.open(CACHE_NAME) .then(function(cache) { cache.put(event.request, responseToCache); }); return response; } ); }) ); FETCH
29. Demo
31. Manifest
32. A manifest describes your web page in an
33. INDEX.HTML <link rel="manifest" href="%PUBLIC_URL%/manifest.json">
34. MANIFEST { "short_name": "Library", "name": “DevUp Library Demo", "icons": [ { "src": "book.png", "sizes": "192X192", "type": "image/png" } ], "start_url": "./index.html", "display": "standalone", "theme_color": "#000000", "background_color": "#ffffff" }
35. Demo
37. Let’s Deploy
39. Github Pages to the rescue
40. PACKAGE.JSON – ADDING GH-PAGES { "name": "library", "version": "0.1.0", "private": true, "homepage": “https://jonathanfmills.github.io/DEVUPPWA”, "dependencies": { "gh-pages": "^1.1.0", … }, "scripts": { "predeploy": "npm run build", "deploy": "gh-pages -d build", } }
