The Definitive Guide to HTML5 WebSocket is the ultimate insider’s WebSocket resource. This revolutionary new web technology enables you to harness the power of true real-time connectivity and build responsive, modern web applications. This book contains everything web developers and architects need to know about WebSocket. It discusses how WebSocket-based architectures provide a dramatic reduction in unnecessary network overhead and latency compared to older HTTP (Ajax) architectures, how to layer widely used protocols such as XMPP and STOMP on top of WebSocket, and how to secure WebSocket connections and deploy WebSocket-based applications to the enterprise. Build real-time web applications with HTML5. This book: Introduces you to the WebSocket API and protocol Describes and provides real-world examples of protocol communication over WebSocket Explains WebSocket security and enterprise deployment

Realtime Web Apps: With HTML5 WebSocket, PHP, and jQuery is a guide for beginner- to intermediate-level web developers looking to take the next leap forward in website and app development: realtime. With Realtime Web Apps, you’ll be able to quickly get up to speed on what HTML5 WebSocket does, how it is going to affect the future of the web as we know it, and—thanks to Pusher’s simple API—start developing your first realtime app today. Using a practical approach rather than focusing on dry theory, Realtime Web Apps will guide you through building your first app using HTML5, CSS3, jQuery, and Pusher. After your initial introduction to the technologies used in the book, you’ll immediately jump into the process of creating a realtime Q&A app that will work on desktop browsers as well as mobile phones (including iOS and Android). In addition to learning realtime development strategies, you’ll also learn progressive development strategies including responsive CSS3 layouts, AJAX development with jQuery, and more. The future of the web is realtime. Grab your hoverboard. Introduces you to the revolutionary capabilities of the HTML5 WebSocket API Gets you started with WebSocket immediately using the super-simple Pusher API Walks you through the development of a real-life realtime web app Gets you working with responsive layouts, jQuery, and AJAX development

Until recently, creating desktop-like applications in the browser meant using inefficient Ajax or Comet technologies to communicate with the server. With this practical guide, you’ll learn how to use WebSocket, a protocol that enables the client and server to communicate with each other on a single connection simultaneously. No more asynchronous communication or long polling! For developers with a good grasp of JavaScript (and perhaps Node.js), author Andrew Lombardi provides useful hands-on examples throughout the book to help you get up to speed with the WebSocket API. You’ll also learn how to use WebSocket with Transport Layer Security (TLS). Learn how to use WebSocket API events, messages, attributes, and methods within your client application Build bi-directional chat applications on the client and server with WebSocket as the communication layer Create a subprotocol over WebSocket for STOMP 1.0, the Simple Text Oriented Messaging Protocol Use options for older browsers that don’t natively support WebSocket Protect your WebSocket application against various attack vectors with TLS and other tools Debug applications by learning aspects of the WebSocket lifecycle

Getting Started with HTML5 Websocket Programming takes a tutorial-based approach.This book is for anyone who wants to build high-performance, true, real-time web applications. Being familiar with frontend web development (HTML / XHTML, JavaScript) would be ideal.

HTML5 is here, and with it, web applications have acquired power, ease, scalability, and responsiveness like never before. With this book, developers will learn how to use the latest cutting-edge HTML5 web technology—available in the most recent versions of modern browsers—to build web applications with unparalleled functionality, speed, and responsiveness. This new edition includes major revisions for WebSockets functionality, reflecting the new W3C specification. It also features new chapters covering the drag-and-drop API as well as SVG. Explains how to create real-time HTML5 applications that tap the full potential of modern browsers Provides practical, real-world examples of HTML5 features in action Covers all the new HTML5 APIs to get you up-to-speed quickly with HTML5 Fully updated to include the latest revisions of the WebSocket API, and much more.

Plugins will soon be a thing of the past. The Definitive Guide to HTML5 Video is the first authoritative book on HTML5 video, the new web standard that allows browsers to support audio and video elements natively. This makes it very easy for web developers to publish audio and video, integrating both within the general presentation of web pages. For example, media elements can be styled using CSS (style sheets), integrated into SVG (scalable vector graphics), and manipulated in a Canvas. The book offers techniques for providing accessibility to media elements, enabling consistent handling of alternative representations of media resources. The Definitive Guide to HTML5 Video dives deep into the markup that is introduced for media element support in browsers. You’ll explore the default user interface offered through browsers for media elements, as well as the JavaScript API provided to control their behavior. You’ll also learn how to account for H.264 and Ogg Theora codecs.

Learn how to use messaging technologies to build responsive and resilient applications for mobile devices and web browsers. With this hands-on guide, you’ll use the STOMP and MQTT messaging protocols to write iOS and web applications capable of sending and receiving GPS and device sensor data, text messages, and alerts. Messaging protocols are not only simple to use, but also conserve network bandwidth, device memory, and batteries. Using this book’s step-by-step format, author Jeff Mesnil helps you work with Objective-C and JavaScript libraries, as well as the protocols. All you need to get started are basic programming skills. Understand basic messaging concepts and composition Learn two common messaging models: point-to-point and publish/subscribe Use STOMP to write an iOS application that sends GPS data, and a web app that consumes the data Build an iOS app with MQTT that tracks and broadcasts device motion data, and a web app that displays the data and sends alerts Extend STOMP to filter, prioritize, persist, and expire messages Take a complete tour of STOMP and MQTT, including features not used in the book’s sample apps
