“I very much enjoyed how this book covers the full Ajax application lifecycle and not only coding techniques. Anyone who is looking to become a professional front-end developer will appreciate the architectural insight and best practices delivered by this book.” — Andi Gutmans, Co-Founder & Co-Chief Technology Officer of Zend Technologies Mission-Critical Ajax: Maximizing Scalability, Performance, Security, Reliability, and Maintainability Advanced Ajax: Architecture and Best Practices is the definitive guide to building business-critical, production-quality Web applications with Ajax. Shawn M. Lauriat systematically addresses the design, architecture, and development issues associated with Ajax, offering proven patterns and robust code examples available in no other book. You’ll find best practices for addressing the full spectrum of issues enterprise Ajax developers face: scalability, performance, security, reliability, flexibility, maintainability, and reusability. Writing for experienced Web developers, Lauriat delivers fresh ideas and elegant solutions: meaty technical content, presented with exceptional clarity. Among the many topics he covers in unprecedented depth: cleanly implementing JavaScript custom events to reduce coupling and to enhance flexibility; overcoming Ajax’s traditional accessibility limitations; reducing network latency through compression and other techniques; and much more. Coverage includes Planning Ajax interfaces for simplicity, clarity, and intuitiveness Creating scalable, maintainable architectures for client-side JavaScript Using the latest tools to profile, validate, and debug client-side code Architecting the server side for security and functionality, while restricting loaded data, objects, and actions to current requests Protecting against the most widespread and significant Ajax security risks Optimizing every component of an Ajax application, from server-side scripts to database interactions Introducing cutting-edge Ajax: game development, Ajax with canvas, and Ajax for enterprise applications About the Web Site This book’s companion Web site (http://advancedajax.frozen-o.com) doesn’t just provide all the code: It shows code examples in action , as building blocks of a real Web application interface.
