Although web components are still on the bleeding edge—barely
supported in modern browsers—the technology is also moving extremely
fast. This practical guide gets you up to speed on the concepts underlying
W3C’s emerging standard and shows you how to build custom, reusable
HTML5 Web Components.
Regardless of your experience with libraries such as jQuery and Polymer,
this book teaches JavaScript developers the DOM manipulations these
libraries perform. You’ll learn how to build a basic widget with vanilla
JavaScript and then convert it into a web component that’s semantic,
declarative, encapsulated, consumable, and maintainable. With custom
components, the Web can finally fulfill its potential as a natively extensible
application platform. This book gets you in at the right time.
■ Understand core concepts (such as normal ow and
positioning, and z-index) for properly positioning, dragging,
and resizing elements
■ Explore UI concepts and patterns typically abstracted away by
Dojo, jQuery UI, Kendo UI, and other libraries
■ Dive into the W3C standard and convert your working widget
example into a fully functioning web component
■ Learn how to encapsulate, package, and deploy your web
components with Google’s Polymer framework
