Gain hands-on experience with the amazing PhoneGap library, using the practical recipes in this handy guide. With these solutions, you can enable your mobile web apps to interact with device-specific features such as the accelerometer, GPS, camera, and address book. Learn how to use your knowledge of HTML, CSS, and JavaScript to build full mobile apps for iOS, Android, and several other platforms without rewriting apps in the native platform language. Each recipe includes sample code you can use in your project right away, as well as a discussion of why the solution works. Add functionality that’s available only on a certain device or platform Retrieve the device’s current GPS location and place a marker on a map Create and save a new contact or edit an existing contact in the address book Take pictures with the camera or select one of the user’s existing photos Upload a file from the local device to an external server Allow the device to record audio or video through your app Enable your application to save files locally

Build an application from backend to browser with Node.js, and kick open the doors to real-time event programming. With this hands-on book, you’ll learn how to create a social network application similar to LinkedIn and Facebook, but with a real-time twist. And you’ll build it with just one programming language: JavaScript. If you’re an experienced web developer unfamiliar with JavaScript, the book’s first section introduces you to the project’s core technologies: Node.js, Backbone.js, and the MongoDB data store. You’ll then launch into the project—a highly responsive, highly scalable application—guided by clear explanations and lots of code examples. Learn about key modules in Node.js for building real-time apps Use the Backbone.js framework to write clean browser code, and maintain better data integration with MongoDB Structure project files as a foundation for code that will arrive later Create user accounts and learn how to secure the data Use Backbone.js templates to build the application’s UIs, and integrate access control with Node.js Develop a contact list to help users link to and track other accounts Use Socket.io to create real-time chat functionality Extend your UIs to give users up-to-the-minute information

Bring dynamic server-side web content and responsive web design together to build websites that work and display well on any resolution, desktop or mobile. With this practical book, you’ll learn how by combining the ASP.NET MVC server-side language, the Bootstrap front-end framework, and Knockout.js—the JavaScript implementation of the Model-View-ViewModel pattern. Author Jamie Munro introduces these and other related technologies by having you work with sophisticated web forms. At the end of the book, experienced and aspiring web developers alike will learn how to build a complete shopping cart that demonstrates how these technologies interact with each other in a sleek, dynamic, and responsive web application. Build well-organized, easy-to-maintain web applications by letting ASP.NET MVC 5, Bootstrap, and Knockout.js do the heavy lifting Use ASP.NET MVC 5 to build server-side web applications, interact with a database, and dynamically render HTML Create responsive views with Bootstrap that render on a variety of modern devices; you may never code with CSS again Add Knockout.js to enhance responsive web design with snappy client-side interactions driven by your server-side web application

Use Knockout.js to design and build dynamic client-side web applications that are extremely responsive and easy to maintain. This example-driven book shows you how to use this lightweight JavaScript framework and its Model-View-ViewModel (MVVM) pattern. You’ll learn how to build your own data bindings, extend the framework with reusable functions, and work with a server to enhance your client-side application with persistence. In the final chapter, you’ll build a shopping cart to see how everything fits together. If you’re a web developer with experience in JavaScript, HTML, and CSS, you’re ready for Knockout. Learn how to create a ViewModel Bind HTML data and attributes, and CSS classes and styles Understand data binding in Knockout’s context hierarchy Use properties that change dynamically through user interaction Work with forms by using several different bindings Bind multiple ViewModels on a single page Extend or attach custom functions to observables Perform server-side interactions with jQuery Map a JavaScript object or apply JSON data to a new object
