Case Study: Iron Services

The large companies that use Dojo are widely known. This series features lesser known users of Dojo, and their stories. This time, we interview Jordi Josa from Iron Services, creator of English Audiobooks – Librivox and other English language learning applications.

Q: Could you tell us your experience with Dojo Mobile Framework?

A: Not long ago I decided to introduce in the world of mobile programming. My idea was to do several applications to help people like me were learning a Foreign language, in this case English. After a search of the various technological options I decided to use Dojo Mobile 1.8 and PhoneGap because they allow do applications for various platforms. I’ve had great success choosing this technology, as my apps work perfectly on Android, iPad and iPhone, even on desktop platforms as Mac and Windows 8.

Since all the components provided by Dijit, such as toolbars, drop-down menus, and tabs closely mirrored desktop application equivalents, the resulting system was intuitive to use, and continues to be used today with no modifications needed to keep updated with the latest browsers. Everything ‘just works’ and continues to do so.

Q: Can you talk about your apps?

Currently I have three free apps on iOS and Android. The first one is an application to read books in English, while listening to the audio. The second is an English dictionary with over 175,000 words and 300,000 definitions. The third is a game to learn vocabulary. All applications can work offline, allowing local downloads of audio and text files. In the first application, I worked with the audio stream, many Dojo controls such as lists, panels, windows and transitions, and used Dojo’s Ajax capabilities to download files from the server. In the dictionary app, I use an SQLite database with over 400,000 records locally. The game allowed me to explore the use of animations, and various facets of HTML5.

Q: What do you like best about Dojo Mobile?

A: It works on multiple platforms, both for desktop (Safari, Chrome, Internet Explorer) and for mobile phones and tablets (iOS, Android, Blackberry, Windows Mobile 8). The large amount of incorporated widgets and themes facilitates rapid application development. Performance is solid, from mid-range phones to powerful tablets.

Q: Have you tried other mobile toolkits?

A: Yes, I tested Sencha and jQuery Mobile, but I chose Dojo because it also works perfectly well on desktop computers, it’s ease of use, and the extensive documentation and examples that were ready to use.

Q: What are your future plans?

A: First is to finish my application versions for Mac and Windows 8 Store. Later, I will try to group them so that I can improve the main objective, which is to provide tools for learning English.

Q: How did you learn about Dojo?

A: Previously, I made several web applications with IBM Domino (XPages), so I could test it extensively. IBM trusts Dojo as a solid foundation for their platform, giving me a lot of confidence in its robustness.

Q: How would you summarize your experience?

A: I really enjoyed building the application so very much, and I think in this way you can see the power offered by PhoneGap, along with Dojo Mobile in a real case study. Feel free to download any of these applications to see Dojo Mobile in action:




Thanks Jordi for telling us about your experience with Dojo. If you would like to share your experience, please contact us.

Dojo is now hosted on GitHub

I’m pleased to announce that after a prolonged period of incomplete mirroring, we’ve now fully migrated Dojo’s source code to GitHub. Future development will be performed there instead of the Subversion repository, which is now read-only and effectively dead. We will continue to use for issue tracking, but patches should now be submitted directly as pull requests. The guidelines in each repository provide guidelines on sending patches.

As an unavoidable part of this update, the old repositories on GitHub have had their histories rewritten. This means that any Git projects with submodules pointing to those old repositories will be broken. If you have such a project, please make sure you update your submodules. The old mirror repositories have been temporarily renamed with an `-oldmirror` suffix so you can find the correct commit ID for your project. These old mirror repositories will be going away in the near future.

Case Study: eEnglish

The large companies that use Dojo are widely known. As part of a new feature, we’re going to start introducing users of Dojo and tell their stories. First up is eEnglish, with an interview of Marty Humphreys.

Q: How did you learn about Dojo?

A: I first found out about Dojo, I think it was version 0.3, while searching for a rich user interface toolkit to aid in rapid development of some internal web-based tools. The first project was a utility that performed DNS record lookups at regular intervals to track changes to the whois information for websites hosted for clients. We called it Dr. Whois. In a record time of only a few days, I was able to get a fully functional app up and running that completely exceeded all expectations and included a lot of handy features that I doubt could have been added in if more time had been spent on working through GUI challenges.

Since all the components provided by Dijit, such as toolbars, drop-down menus, and tabs closely mirrored desktop application equivalents, the resulting system was intuitive to use, and continues to be used today with no modifications needed to keep updated with the latest browsers. Everything ‘just works’ and continues to do so.

Q:Why did you choose Dojo?

A: Given the early successes, there was a natural gravitation towards Dojo when a port to HTML was required for a sister company‘s English pronunciation learning software, eEnglish.

Despite a very rapid release schedule, tight deadlines, multilingual and multimedia requirements, and very complicated user interface component interactions, it was relatively easy to mold Dojo to do exactly as we needed. Honestly, with regards to how nicely all the Dijit widgets snapped together, combined with the robustness of the utility functions that the Dojo core provided, what initially took many years to build as a desktop program took a fraction of the time to deploy as a web application.

We were able to draw upon years worth of assets such as video and audio clips, but nonetheless, after restructuring everything as HTML there was time left to extend the product beyond the original capabilities, adding in features such as a speech test (find out what parts of speech you have most difficulty with) and a vocabulary building component, while still improving details like animations and transitions, and also creating a great administration dashboard.

Q: Were you previously using another toolkit?

A: Yes, other projects were built upon other frameworks, including SproutCore, jQuery UI, TikiWiki, and ExtJS, all to varying degrees of success. It is a matter of picking the right tool for the job; for applications that depend on reusable, stylish, well-behaved components in complicated, heterogeneous systems, Dojo really shines. Being able to easily mix and mash widgets around alongside other libraries like soundmanager2, swfobject, and still be able to freely use vanilla html when needed was a huge plus.

Q: How does your application use Dojo?

A: Initially, eEnglish only made extensive use of the the Dijit interface components, however as the project grew it became necessary to bring in other modules like dojo/data and dojo/store to make dealing with database resources much more simple to manage and reuse. We started with version 1.2 and kept upgrading Dojo alongside the project as it was developed and I was always pleasantly surprised to find that with each version bump almost none of the existing code broke, and usually some new feature landed that solved some problem like adding in stylish graphs charting a person’s progress. I’m not exactly sure what version the final product is using, as we ended up migrating to the source trunk to keep up with the bleeding edge, but dojo.version lists it as revision 22487.

Q: Overall, what is your experience with Dojo?

A: Getting everything running smoothly was really low stress, and pain free. I liked that. It was completely possible to build in a very organic fashion, adding in code where it was needed, have it auto-magically load on demand, and not fret about a new commit breaking some other part of the site. Maybe as a result of this there was a bit too much monkey patching happening but it worked as a development strategy. After all of the main parts were built and put together, lessons, example sentences, listening discrimination, speech analyser, dictionary, etc, etc, etc, and were working well, it was a joy to make some small overrides in a few key places, namely the Claro Dijit theme and watch the app totally transform its style to fit exactly what we were looking for.

Q: What’s your favorite thing about Dojo?

A: There is a lot to like about Dojo, at first there were some concerns about page load speed, but after making a custom Dojo build that included only the parts of it that we were using we got an amazing improvement, and now the site loads super fast, doubly so if it’s cached. With the module based system, it is great to know that it is a cinch to drop in almost any functionality on-demand. Being able to intermingle declarative widget creation with a programmatic approach was also a big win for us.

Q: What are your future plans with Dojo?

A: There is still a lot of room for eEnglish to grow and mature as a product for english learners and I hope to continue to improve upon it as more people find out about it and give it a go. For future projects I will certainly be keeping Dojo near the top of my developer toolbox as it is one of the most versatile yet stable projects out there for applying rich user interfaces and great functionality to web applications.


Thanks Martin for telling us about your experience with Dojo. If you would like to share your experience, please contact us.

Dojo Foundation provides €500 match to assist development of UglifyJS 2.0

Today, the Dojo Foundation board voted to approve a €500 match to the jQuery Foundation’s financial grant to the developer of UglifyJS, Mihai Bazon.

This grant is being provided to help speed development of the next major version of the open-source UglifyJS code compression library, which is a significant rewrite designed to provide better extensibility for new features like source maps and more aggressive compression methods. (UglifyJS is planned to be the replacement for ShrinkSafe in Dojo 2.0.) We’re very excited to be able to provide additional assistance to this extremely important project, and hope that others will be inspired to pitch in as well. Together, we can do amazing things!

Dojo 1.8 Released!

The Dojo team is very excited to announce the immediate release of Dojo 1.8, our last major release before the big 2.0!

This release would not have been possible without significant contributions from the Dojo team. Special thanks to Colin Snover, Bill Keese, Dylan Schiemann, Rawld Gill, Ken Franqueiro, Bryan Forbes, Kitson Kelly, Brian Arnold, Doug Hays, Christophe Jolif, Mark Wubben, Doug Hays, Yoshiroh Kamiyama, Kris Zyp, Patrick Ruzand, Adam Peller, Evan Huang, and dozens of others, and to IBM, SitePen, AltoViso, and Research in Motion for their generous contributions of development time and financial support.

With that out of the way, let’s talk about what’s new in Dojo 1.8!

Better Documentation

The top goal of Dojo 1.8 was to significantly improve the quality of our documentation. In order to achieve this, in this release, we’ve:

  • made more than 500 fixes to our documentation based on community feedback (thank you!)
  • re-organized and committed over 1500 changes to our reference guide
  • developed a brand new, extensible JavaScript-based documentation parser, which we use to generate output for the API viewer
  • significantly enhanced the API viewer with full AMD support, module cross-linking, property source information (useful for modules that are augmented by other modules, like dojo/NodeList), and other improvements

We’re still in the process of updating the Dojo tutorial series to bring you the latest and greatest advice, but over 70% of our existing tutorial series have already been updated, with the remainder to be completed in the coming weeks. We’re also adding ten brand new tutorials to teach you about the new features added to Dojo 1.8. We’ll be announcing the remaining tutorials as they are released on our Twitter account (@dojo), so keep an eye out there.

New Features

Dojo 1.8 isn’t all documentation, of course! We’ve also been hard at work adding several major new features to the toolkit that we think you’ll enjoy. These new components include:

dojo/request: A cross-platform AJAX component, designed to be more flexible and extensible than the existing dojo/_base/xhr component (which it deprecates). Notable new features of this component include the ability to perform AJAX calls from Node.js, XHR2 support, and a mechanism for registering handlers to convert arbitrary response payloads into usable objects.

dojo/node: A new loader plugin that enables server-side code to load Node.js/CommonJS modules from within the AMD loader.

dojo/router: A component that enables client-side applications to register and navigate between discrete “pages” that change based on the current browser URL, like the navigation of a “traditional” server-side application.

dojo/promise: A redesigned, Promises/A-compliant deferreds/promises implementation which deprecates dojo/_base/Deferred. Notable new features include improved instrumentation and error handling, an easier-to-use API, and a reduced footprint for applications that only need a subset of its features.

dijit/Destroyable: A new base widget class that makes it easier to ensure event handlers, topic subscribers, and other connections are properly cleaned up when their owner objects are destroyed.

dojox/Calendar: A new, feature-rich calendaring widget that enables you to quickly and easily create event calendars. View a demo.

dojox/dgauges: A new framework for creating graphically rich gauges used to represent and manipulate data. View a demo.

dojox/treemap: A component for creating treemap data visualizations. View a demo.

In addition to these all-new features, we’ve also significantly enhanced several other components from earlier versions of the toolkit. Some of the more notable improvements include:

  • dojox/mobile includes 28 new mobile widgets including audio, video, grid layout, and tree view. (View a demo.)
  • dojo/dnd and dojox/gfx are both now fully functional on mobile devices.
  • dojo/parser now accepts AMD module IDs in the data-dojo-type attribute. It also includes a new asynchronous mode that allows modules to be automatically required based on the data-dojo-type attribute if they haven’t been explicitly required yet.
  • dojo/Stateful now allows the use of getter and setter functions; previously, only dijit/_WidgetBase enabled getter/setter functions.
  • Dijit’s Claro theme now uses CSS3 gradients instead of images in browsers that support it.
  • DOH Robot now works with the loader set to asynchronous mode.

A more exhaustive list of new features and enhancements can be found in the Dojo 1.8 release notes, along with some migration instructions for any changes that are known to be incompatible with code written for Dojo 1.7 and earlier. The complete list of 971 new features, enhancements, and bug fixes can be found at the bug tracker.

What’s Next? 1.8.1 and 2.0

Now that we’ve released our “final” version of the Dojo 1.x series, we’re moving full speed ahead into planning for Dojo 2.0! In the meantime, we’ll continue to issue maintenance releases for all major Dojo versions 1.4 and later as necessary to ensure your apps continue to work well into the future. We’ll also be releasing a Dojo 1.8.1 release in the next 2–6 weeks to address any bugs that were introduced in Dojo 1.8.

We’ll be providing more information on the blog shortly about our vision for Dojo 2.0 and how you can help to make it the best version of Dojo ever.


We hope you’ll find Dojo 1.8 to be exceptionally stable and reliable. However, if you do run into any issues, please let us know by open a ticket. If you find a problem in the documentation, you can also provide feedback via the link at the bottom of every page. Otherwise, enjoy the release!

Dojo 1.8.0 tagged, official release August 15

Well, it seems there’s no such thing as a soft launch when it comes to open source software. 🙂 We’ve tagged the final code for Dojo 1.8.0 in our git and subversion repositories and submitted it to our CDN partners, but you won’t find it on yet because we’re still finishing up some needed final updates to the site and documentation. In less than a week, on August 15, we’ll be officially releasing the latest version of Dojo, along with a raft of new documentation and detailed information on all the new features included in this release. In the meantime, hang tight, and we’ll be all set next Wednesday for the grand unveiling.
