4. Web Components: Overview
5. What problems are we solving?

13. <paper-tabs> <paper-tab>KNOWLEDGE</paper-tab> <paper-tab>HISTORY</paper-tab> <paper-tab>FOOD</paper-tab> </paper-tabs> Less Code. Less confusion. Web Components
14. What are Web Components?
15. Custom Elements define new HTML/DOM elements
17. <paper-tabs selected=“1”> <paper-tab>Tab 1</paper-tab> <paper-tab>Tab 2</paper-tab> <paper-tab>Tab 3</paper-tab> </paper-tabs> declarative, readable meaningful HTML common way to extend → reusable Custom Elements define new HTML @polymer #itshackademic
18. declarative, readable meaningful HTML common way to extend → reusable Custom Elements define new HTML var tabs = document.querySelector('paper-tabs'); tabs.addEventListener('core-activate', function() { console.log(this.selected); }); @polymer #itshackademic
19. Templates native client-side templating
20. <template> <div class=“comment”> <img src=“image.png”> </div> <script>...</script> </template> use DOM to scaffold DOM → no XSS content is inert until cloned/used doc fragment → not part of the page HTML Templates native client-side templates parsed, not rendered @polymer #itshackademic
21. Shadow DOM DOM/CSS scoping
22. <video src=“foo.webm” controls></video> @polymer #itshackademic
23. <video src=“foo.webm” controls></video> Actually Shadow DOM @polymer #itshackademic
24. <video src=“foo.webm” controls></video>
25. HTML Imports loading web components
26. @polymer #itshackademic
27. @polymer #itshackademic
28. Vulcanize $ vulcanize -o build.html index.html \ --csp --strip npm install -g vulcanize
29. grunt-vulcanize
30. gulp-vulcanize
31. Custom Elements Create new HTML elements and extend existing ones Templates Native templating in the browser Shadow DOM Scoped CSS!!! + encapsulated markup HTML Imports Load custom element definitions and resources

36. Browser support Summer 2014
38. Polyfills Web Components with webcomponents.js * previously called platform.js *
39. Adds syntactic “sugar” with polymer.js
40. Browser support Summer 2014 (with Polymer)
41. Browser support Summer 2014 (with Polymer)

108. I want to add a marker to a Google map. @polymer #itshackademic
109. } </style> <div id="map"></div> <script src=“http://maps.googleapis.com/maps/api/js?callback=mapReady"> </script> <script> var marker = null; function getCurrentLocation(callback) { navigator.geolocation.watchPosition(callback); } function addMarker(opts, info) { var marker = new google.maps.Marker(opts); var infoWindow = new google.maps.InfoWindow({content: info}); google.maps.event.addListener(marker, 'click', function() { infoWindow.open(opts.map, marker); }); return marker; } function mapReady() { var container = document.querySelector('#map'); var map = new google.maps.Map(container, { zoom: 14, disableDefaultUI: true }); getCurrentLocation(function(pos) { var current = new google.maps.LatLng(pos.coords.latitude, pos.coords.longitude); map.setCenter(current); // Re-position marker or create new one. if (marker) { marker.setPosition(map.getCenter()); } else { marker = addMarker({ position: current, map: map, title: 'Your location' }, '<b>Your location</b>'); } So much code for one map marker! @polymer #itshackademic
