Discover Ext JS, one of today’s most powerful and highly regarded JavaScript frameworks, with perhaps the best set of GUI widgets around, and a whole host of components that make developing client–side applications a breeze. Using a pragmatic approach, you’ll dissect seven full–fledged applications, covering How Ext JS allows you to create these applications with a slick user interface with a minimum of effort How the other parts of Ext JS aside from the GUI widgets provide many of the capabilities modern applications need, such as Ajax and data mechanisms How other technologies such as Gears can be brought in to make the applications more powerful

The era of professional JavaScript development has arrived! Gone are the days when writing all the client–side code for your applications by hand yourself was the norm. Gone are the days when scrounging around the Internet to find a snippet of code to do something you need could lead to either decent code or utter garbage that you'd surely regret using later. No, writing high–quality JavaScript these days is a whole lot easier with the advent of top–notch libraries that save you time and effort, and one that stands out from most others is Dojo. Dojo is a library like few others: written by some of the best JavaScript coders around today, providing nearly everything you'll need to write modern rich Internet applications, all in one place. From Ajax to widgets, to client–side persistence and language extensions, and many points in between, Dojo has it all. In Practical Dojo Projects, you'll learn all about what Dojo has to offer. You'll see it in action in the form of five fully functional applications, which include A contact manager for storing info for all the important people in your life A code cabinet: a place to store, index, and get code snippets from A stock tracker to keep track of your stock portfolio A message forum for open discussions on topics you define Even a fun little game! By the time you've finished reading, you'll have a firm grasp on what Dojo is all about, and you'll have the preparation you need to begin to use it yourself in your own projects. See you inside!

Create bulletproof, high-performance web apps and servers with Rust. In Rust Web Development you will learn: Handling the borrow checker in an asynchronous environment Learning the ingredients of an asynchronous Rust stack Creating web APIs and using JSON in Rust Graceful error handling Testing, tracing, logging, and debugging Deploying Rust applications Efficient database access Rust Web Development is a pragmatic, hands-on guide to creating server-based web applications with Rust. If you’ve designed web servers using Java, NodeJS, or PHP, you’ll instantly fall in love with the performance and development experience Rust delivers. Hit the ground running! Author Bastian Gruber’s sage advice makes it easy to start tackling complex problems with Rust. You’ll learn how to work efficiently using pure Rust, along with important Rust libraries such as tokio for async runtimes, warp for web servers and APIs, and reqwest to run external HTTP requests. About the technology If you’re sick of cookie-cutter web development tools that are slow, resource hungry, and unstable, Rust is the solution. Rust services deliver rock-solid safety guarantees, an amazing developer experience, and even a compiler that automatically prevents common mistakes! About the book Rust Web Development, teaches you to build server-side web apps using Rust, along with important Rust libraries like tokio for async runtimes, warp for web servers and APIs, and reqwest to run external HTTP requests. The book is packed full of examples, code samples, and pro tips for setting up your projects and organizing your code. As you go, you’ll build a complete Q&A web service and iterate on your code chapter-by-chapter, just like a real development project. What's inside Handle the borrow checker in an asynchronous environment Build web APIs and handle JSON Compose a tech stack for asynchronous Rust development Handle errors gracefully Test, trace, log, and debug Deploy Rust applications to multiple environments About the reader This book is for web developers familiar with Java, Node, or Go, and the absolute basics of Rust. About the author Bastian Gruber was part of the official Rust Async Working Group, and founded the Rust and Tell Berlin MeetUp group.

Is it possible for JavaScript programmers to learn Apple's iOS 4 SDK and live to tell the tale? Technology guru Danny Goodman did, and with this book he leaves a well-marked trail for you to follow. An authority on JavaScript since its inception, Goodman understands the challenges you might face in creating native iOS apps with this SDK, and introduces Xcode, Objective-C, and Cocoa Touch in a context you'll readily understand. Why bother with the SDK when you can simply build web apps for Apple's iOS devices? Web apps can't access an iPhone's music library, camera, or iOS system software for maps, audio, and more. Nor can you sell web apps in the App Store. If you want to take full advantage of the iPhone and iPad, iOS 4 SDK is your tool -- and this is your book. Includes full coverage of iOS SDK 4.2. Learn the distinction between web app and iOS native app programming Create a workbench app to test code snippets throughout the learning process Get a structural view of an iOS app, and compare the process of building objects in Objective-C versus JavaScipt Discover how your code launches iOS apps and makes them user-ready Learn about iOS memory management details that are different from JavaScript, including pointers and data types Use Objective-C and Cocoa Touch to implement common JavaScript tasks
