Take advantage of your existing JavaScript and HTML skills to build apps for Windows 8.1 and add them to the Windows Store. It’s a remarkable opportunity—and best-selling Microsoft web development author Stephen Walther will show you how to take full advantage of it.

Offering the same deep insight and practical code that has made his ASP.NET Unleashed the #1 ASP.NET book of all time, Walther covers everything you need to build outstanding Windows Store apps with JavaScript and HTML5.

He guides you through using Microsoft’s WinJS 2.0 library to develop apps for Windows 8.1—you learn how to use JavaScript templates, controls, and data binding. You’ll find in-depth coverage of everything from displaying data with a ListView control to supporting SkyDrive cloud storage, creating games to using IndexedDB and HTML5 forms.

Extensively updated for the release of Windows 8.1, this book covers all of the new features of the WinJS 2.0 library such as the Repeater, SearchBox, WebView, and NavBar controls and the new WinJS Scheduler. This book has been updated with a new sample app that demonstrates how to build a Windows Store app that interacts with Windows Azure Mobile Services.

If you’re a web developer, Windows 8 gives you millions of new potential customers to buy your apps—and you already have many of the skills you’ll need to reach them. Get this book, master the tools and techniques you don’t already know—and go after that huge new market!

Detailed information on how to…

  • Get your app published in the Windows Store
  • Use JavaScript controls such as the Tooltip, Rating, DatePicker, and FlipView controls
  • Thoroughly master using the WinJS ListView control to display, sort, and filter data
  • Use new controls introduced with Windows 8.1 such as the Repeater, WebView, NavBar, and SearchBox controls
