A Note from the Author and from O'Reilly Media about what this bookdoes--and doesn't--do:
Palm webOS is a brand new platform and represents a very different type ofoperating system where the web runtime is used as the basis for the UI andApplication model. Palm and O'Reilly felt that it was important to have abook available to help developers get a basic understanding of the new Palmplatform at the time that the SDK was released; this timing played a majorrole in the content and structure of the book.
Ideally this book would have been a complete reference of the new platformbut that wasn't possible since the content was written at the same time asthe software SDK was being developed by the Palm engineering team. The bookdoes provide a complete overview of Palm webOS, a thorough description ofthe application model and gives details on many key design concepts. Thereare descriptions and examples of UI widgets, services, storage,notifications, dashboards and background applications, serving as a greatintroduction but not as a definitive source.
The book uses a simple News reader application to illustrate the technicaldescriptions but the examples are not intended to serve as a cookbooktutorial. Experienced developers should be able to use the examples to buildup a working application chapter by chapter but others may not find theloose descriptions adequate for recreating the application unaided. Overtime, these different needs will be filled by other books, but in themeantime we hope that this book will serve a valuable role introducingdevelopers to webOS and giving them a way of getting started with webOSapplication development.
A second printing of the book will update any original coverage obsoleted bysubsequent Mojo SDK builds. For owners of the original printing of the book,all of these updates are posted on the "View/Submit Errata" link (please seeleft-hand column of this web page).
Thanks for understanding that book publishing and coverage of rapidly movingtechnologies can sometimes be an inexact science; we knew there'd be a needfor a book such as Palm webOS: The Insider's Guide to DevelopingApplications in JavaScript using the Palm MojoT Framework, and there'scertainly no better person to write that book that Mitch Allen; that said,we understand that because it is such a new operating system and SDK, therewould (and will continue to be) changes that at best can't be documented andexplored until new printings of the books are released. In the meantime wewill be diligent in posting updates to this book's O'Reilly Media catalogpage. DescriptionThis is the official guide to building native JavaScript applications for Palm's new mobile operating system, Palm® webOS™. Written by Palm's software chief technology officer along with the Palm webOS development team, Palm webOS provides a complete tutorial on the design principles, architecture, UI, tools, and services necessary to develop webOS applications-including the Mojo JavaScript framework and Palm's SDK. Palm webOS is designed to support a fast and superb user experience using established web standards, so if you're familiar with HTML, CSS, and JavaScript, you're ready to build applications for any webOS-based device, including the Palm Pre. You'll gain expertise, chapter by chapter, as you build a working mobile application through the course of the book. You'll also learn how to extend existing web apps to work with the new generation of mobile phones. - Get a thorough overview of the webOS platform and architecture
- Understand the critical concepts for application design: what separates webOS from other web and mobile platforms
- Learn the details of Mojo's development tools and SDK for building and testing mobile applications
- Examine best practices, important considerations, and guiding principles for developing with webOS and the Mojo framework

Mitch Allen Mitch Allen is CTO of Software at Palm, Inc. where he has worked in various positions for 8 years starting with building and leading the software team at Handspring which conceived and developed the Treo smartphone. From webOS's conception to implementation, Mitch designed the early architecture of the webOS platform and led the development team through the initialdesign stage and as a result is intimately familiar with the capabilities of the platform and tools. He is currently leading the design of the developer SDK and toolsets, and working with initial developers in their use of the platform and SDK.
Previously, Mitch worked at Apple, after 15 years developing image and text processing systems at Kodak and Agfa Compugraphic. He holds a degree in Math and Computer Science from the University of New Hampshire. View Mitch Allen's full profile page. |
Colophon The animal on the cover of Palm webOS is a luna moth (Actias luna). Luna moths usually live in North American regions filled with black cherry, maple, hickory, willow, and other trees with leaves that can feed their young. Upon hatching, luna moth caterpillars will wander aimlessly along the plants they were born upon and befriend other recently born caterpillars. But after passing through subsequent stages of larval development, the caterpillars' gregarious temperaments change, and they become loners as they prepare for pupation. Before spinning and entering their thin cocoons, luna moth caterpillars will expel excess water and other fluids from their bodies. Once cocooned, the caterpillars will pupate for approximately two weeks, after which they will emerge in daylight with wet, crumpled wings. Although their wings take only 20 minutes to dry, luna moths will wait until nighttime to fly, as they have also metamorphosed into entirely nocturnal creatures. While the caterpillars will munch on the leaves of the plants they were born upon, luna moths begin and end their adulthoods mouthless. But this trait does not disable them: they have no need for food, as they have also lost their digestive tracts. Though other insects will forage for food shortly after birth, luna moths exist only to find a mate and produce another generation. Female luna moths attract mates by releasing pheromones from their abdomens; males detect these pheromones via their hairy antennae (and, because males and females both possess lime-green wings, a close inspection of a moth's antennae is an easy way to determine gender, as the male's antennae are hairier than the female's). Luna moths typically mate after midnight, and females will lay 100 to 300 eggs on the undersides of leaves just hours later, in the evening. The insect's short lifespan necessitates an accelerated reproduction schedule-adult luna moths live no longer than a week. Luna moths have inspired many: Luna Moth is the name of a character in Michael Chabon's novel The Amazing Adventures of Kavalier and Clay (Picador), and Vladimir Nabokov, who was also an accomplished lepidopterist, has described the insect admiringly in his writings. Crafters have also paid homage to the insect's vivid wings with products ranging from shawls to stained glass. Luna was also Palm, Inc.'s code name for the webOS application environment, including the Mojo framework. The cover image is from Dover's Animals. The cover font is Adobe ITC Garamond. The text font is Linotype Birka; the heading font is Adobe Myriad Condensed; and the code font is LucasFont's TheSansMonoCondensed. |
