Getting the Most out of Dojo

Peter Higgins

Dojo provides a hoard of utility functions to accomplish everyday tasks. Learn how to use and augment the stock library using Dojo's extension APIs and professional JavaScript techniques to create a custom-fit Core Dojo library suited for your every need. See how to use and create powerful plugins such as 'plugd', or 'dojoType' - creating a Dojo version that "feels" like other libraries, but in the end is all "just JavaScript".

Peter Higgins is the Dojo Toolkit Project Lead, and a JavaScript engineer at Joost. He is the co-found of DojoCampus.org , the online community resource for everything Dojo, and runs the Dojo.cast() with Nikolai Onken and Wolfram Kriesing

Hit the Ground Running: Code Generation with Dojo

Sam Foster

There is sufficient repetition to the tasks asked of front-end developers that code generation looks like an attractive proposition. We'll discuss an approach that embodies Dojo best practices, while remaining flexible and extendable enough to meet a range of use cases.

Sam Foster is a Dojo committer and Software Engineer at Sitepen where he's worked on web apps, performance analysis & optimization, Dojo support and recently the development of training materials for Dojo. He's spoken on Dojo at regional conferences, and evangelizes it as a practical and productive toolkit wherever he goes.

Debugging Dojo Applications

Chris Barber

There's no right or wrong way to debug Dojo code, but there's probably an easier way and that's what this talk is about. When something isn't working, knowing what to look for and where to find it is key. You'll learn how to use various debugging tools and techniques to track down and fix issues. This session will cover:

• Common mistakes and how to avoid them
• Web browser debug tools
• Built-in Dojo debugging tools
• Methods for finding and fixing syntax issues or malformed data
• Writing tests to trap specific bugs

Chris Barber is a consultant based in Minneapolis, MN specializing in rich web application development using open web technologies. He is an active Dojo committer and has given several Dojo-related talks at local user groups, BarCamps, and Dojo developer days.

Applying REST Principles to Client/Server Architecture

Kris Zyp

In this session, we will examine how we can build a solid client server architecture, applying principles from the REST architectural design.We will see the tools that the Dojo Toolkit provides for building applications with clean clear separation of concerns, building on Dojo's data infrastructure, and learn best practices based on adopted standards. More specifically we will be looking at how to use the JsonRestStore and how to use many of the extra modules that tie into it. JSON Schema can be used as a definition for client-server contracts with RESTful data hyperlinking, JSON querying methods can be used client and server side, and REST Channels Comet can be integrate with the JsonRestStore as well. We will explore the different mechanisms for communicating with servers from other domains while maintaining proper defenses against XSS and CSRF.

Kris Zyp is a Software Engineer at SitePen where he builds web app tools, and researches client/server communication, comet messaging, JSON data interchange, and high performance Ajax applications. Kris is the lead of the Persevere project and the JSON Schema specification and is an active committer for the Dojo toolkit. He has also been heavily involved in several standards comittees including the W3C webapps group, EcmaScript committee, and the OpenAjax steering committee.

Introduction to Comet with Dojo

Dylan Schiemann

While seen as bleeding edge only a couple of years ago, Comet techniques for achieving bi-directional communication with the server from a browser, are frequently used on applications large and small. Dojo was the first mainstream JavaScript library to support the techniques and in fact the Dojo Foundation hosts the cometD project. In this session we will explore why and when to use comet techniques and how Dojo is applied to these solutions. Dojo integrates nicely with the cometD projects implmentation of the Bayeaux protocol, but it isn't limited to that. We will also see how to use Dojo with other comet systems such as Persevere, Orbited, and js.io.

Dylan Schiemann is CEO of SitePen and co-founder of the Dojo Toolkit, an open source JavaScript toolkit for rapidly building web sites and applications, and is an expert in the technologies and opportunities of the Open Web. Under his guidance, SitePen has grown from a small development firm to a leading provider of inventive tools, skilled software engineers, knowledgeable consulting services, and top-notch training and advice. Dylan is a contributing author to the O'Reilly book "Even Fast Web Sites". Dylan's commitment to R&D has enabled SitePen to be a major contributor to or creator of pioneering open source web development toolkits and frameworks like Dojo, cometD, DWR, and Persevere. Prior to SitePen, Dylan developed web applications for companies like Renkoo, Informatica, Security FrameWorks and Vizional Technologies. He is a co-founder of Comet Daily, LLC, a board member at Dojo Foundation and a member of the Advisory Board at Aptana. Dylan earned his Masters in Physical Chemistry from UCLA and his B.A. in Mathematics from Whittier College.

Rapid Application Development with Dijit

Mike Wilcox

This presentation will get right into a live code-along where we will create a series basic widgets that we will quickly assemble into an application. We will use a modular construction that lets the Dijit Framework do the heavy lifting, and we'll explore event-based programming. The code will be organized so that not only will the build process be easy, but we'll even do a pre-build, so development time will be faster.

Mike Wilcox is Director of Technology at Media Distribution Solutions in Frisco Texas. He is a regular speaker on AJAX and other web technologies and has recently given several presentations at the 2009 Rich Web Experience, and before that, at the Dallas TexFlex, and DallasTechFest. As co-founder of the JavaScript user group in Dallas, Club AJAX, Mike has spoken on topics that include "The JavaScript Programming Primer" and "JavaScript Object Oriented Inheritance".

Mike is a key committer for the new Deft project in Dojo that implements most of the Flash-based components used in DojoX, like the File Uploader and the Video and Audio controls. He is also a primary committer of the Dojo extensions for Adobe AIR. His last project was the vector-based DojoX Drawing, and he is currently working on DojoX CSS3.

Accessible Rich Internet Apps

Becky Gibson

Learn about Web Accessibility and how Dojo supports building accessible rich internet applications by making all of the dijit widgets accessible. Learn the basics of WAI-ARIA - the Accessible Rich Internet Application specification from the Web Accessibility Initiative of the W3C. See how ARIA has been incorporated into the dijit widgets to make them fully keyboard accessible and usable by assistive technologies such as screen readers. Understand Windows High contrast mode and how dijit provides widgets that are usable with CSS and colors turned off to support low vision! Learn the features that have been incorporated into dijit to assist in building accessible widgets. See and hear a demo of the Demo Mail app using a screen reader. You can make rich internet applications accessible - it is easy using Dojo!
