HTML5 is not just a replacement for plugins. It also makes the Web a first-class development environment by giving JavaScript programmers a solid foundation for building industrial-strength applications. This practical guide takes you beyond simple site creation and shows you how to build self-contained HTML5 applications that can run on mobile devices and compete with desktop apps.

You’ll learn powerful JavaScript tools for exploiting HTML5 elements, and discover new methods for working with data, such as offline storage and multithreaded processing. Complete with code samples, this book is ideal for experienced JavaScript and mobile developers alike.

Store session data in the browser with local storage objects
Save trips to the server: store larger amounts of data with IndexedDB
Give browsers limited access to a user’s system to read and upload files
Take your app offline—and speed up page loading when it’s online
Use Web Workers to create multithreaded applications
Transfer data between browser and server more efficiently with Web Sockets
Learn about HTML5 tags for forms, multimedia, graphics, and geolocation

"HTML5 is all the rage these days, but it's more than just a buzzword. Programming HTML5 Applications provides the knowledge to guide you through all the new technologies needed to make modern web applications."

--Ralph Whitbeck, cohost of The Official jQuery Podcast
