Introduction to the Dojo Toolkit

The Dojo Toolkit is a robust toolkit for creating JavaScript-based web applications. I

In this talk you will learn about:

• The origins of the toolkit
• A high level overview of features and project direction and philosophy
• A comparison with other Ajax toolkits

Comet and the Real-time Web

Sometimes Ajax isn't fast enough. For applications with frequent updates or large amounts of data transit such as chat or real-time data display, Comet is the answer.

In this session, you'll learn about the techniques, protocols, servers, and clients that are commonly classified as Comet.

Large-Scale Ajax Application Architectures

When your web application goes beyond the simple inclusion of a few lines of script and becomes a full-fledged application, there are a variety of strategies and patterns to consider that vary based on a number of factors:

• type of application
• network characteristics
• approach to APIs and the type of application you are delivering, the network and server

We'll conclude this session with a review of performance optimization techniques and tips.

Now What?

The past few years have seen a massive proliferation of platforms and approaches to developing web applications. Life used to be simple: target two browsers and you were done.

Now, we have a multitude of new browsers in a variety of environments including mobile, offline, desktop, web operating systems, and more. Distribution of web applications is changing too, with social platforms, app stores, and other deployment options becoming popular... it's become vogue to have applications that require a simple installation step! So what should a developer do next? What's coming down the road and where are things going? This talk will explore where the web world is going.

Programming to Patterns

The JavaScript frameworks make it increasingly easy to write highly expressive and concise functionality that enhances an HTML component, but the power of JavaScript's somewhat hidden inheritance model shouldn't be lost in that power. As programmers gain greater control over user experience design, it's more important than ever to write functionality that is reusable, scalable, and as cheap to maintain as possible without affecting performance. Architecting nearly everything you author into objects that can be extended and reused presents a lot of benefits. T

The speakers (Aaron Newton of MooTools and Dylan Schiemann of Dojo) will each tackle the same problem with code examples in MooTools and Dojo to illustrate the concept.

Dojo 2.0: Modular, Mobile, and Reinventing Web App Development

The Dojo Toolkit is one of the original Ajax toolkits, and has reinvented itself again through a series of improvements in modularity, performance, API improvements, adjustments for HTML5 and mobile platforms, and much more to provide a stellar platform for building web apps.

Learn how Dojo's adoption of CommonJS AMD makes it a perfect toolkit for including source code from other microtoolkits, to create the most extremely optimized JavaScript toolkit for your application, big or tiny. Learn about the wide variety of new features and approaches that are available now in Dojo, as well as the forthcoming Dojo 2.0 release.

Real Time, Real Fast

As web applications continue to become more interactive and sophisticated, real-time messaging and updates are becoming increasingly prevalent. One of the hottest new APIs in HTML5 is WebSocket, which enables true duplex communication without the overhead, complexity, and extraneous latency of HTTP-based solutions. See how the WebSocket removes these barriers to create optimal real-time delivery of messages from servers to browsers, including mobile. Although WebSocket is an exciting new API, we can easily fallback to HTTP-based techniques when WebSocket is not available with Dojo?s Socket API. The server-side is equally important, and real-ti me messaging has pushed the need for asynchronous I/O in the server. The Tunguska library is one example of create scalable real-time applications using the Node.js platform that is so perfectly suited for Comet.

This presentation will also cover the use of streaming abstractions to minimize buffering, and will consider the performance implications of topic-based publish-subscribe distribution versus filtering techniques.

Never Bet Against the Open Web

The open web is quickly either replacing, diminishing, or lowing the barrier to entry for all native platform capabilities. Strategies for logically separating data and user experience concerns create web app architectures that are easy to modify to work anywhere.

We'll talk through engaging examples, and as an audience, make our predictions for when the web will be viable in emerging areas.
