Responsive App Development using Titanium

Snowciety’s co-founder Ronald Treur will do a follow-up on the topic he discussed last January: Fundamentals - Making the most of your single thread. This time he will show you a JavaScript class that might change the way you create apps with Titanium forever.


• 17:30 Walk-in Lab

• 18:30 Free pizza & drinks

Walk-in lab

From now on, be sure to bring your laptop and test devices, 'cause we get hands-on! Get to Glimworm HQ straight out of work to get help with your daily issues. And after hearing the latest on Titanium, learn how to use it in your projects right away! Plenty WiFi, power and tables, don't worry.

Subject: Responsive App Development using Titanium

Last January Ronald talked about keeping your app responsive by making the best use of the single thread that runs all your Javascript logic. The primary tool to accomplish this turned out to be Underscore's defer-function. For those who missed this talk, please check out this (lengthy 3-part) article on Keeping Your App Responsive.

Unfortunately the extensive use of defer throughout your application comes with some new pitfalls. Understanding and circumventing these pitfalls might seem like a huge obstacle when trying to incorporate the defer-mechanic into your application.

In order to better understand what is going on Ronald will show you a live demo of a demo app that has defer built into it from the start. He will explain the structure of the app and how the TaskManager.js file works that he created for this purpose.


Ronald Treur has been working with Titanium for over two years now. Together with Timan Rebel, he created the social wintersports app "Snowciety". Originally coded using Titanium 1.6, the app was completely rewritten using Alloy in 2013.

Using Alloy as a foundation, Ronald wrote a framework on top of it that offers more options and flexibility and at the same time increases the level of abstraction and cohesion. Dubbed "Frost(ium)", this framework is currently closed source and used exclusively by Snowciety. If however, he ever manages to clone himself, he promised to open source it.

    I was asked specifically to not delay putting the TaskManager online, even when unfinished or riddled with bugs. I did however delay it a few days, for which I offer my apologies! It's hard putting incomplete code online ;-)

    As it is however, it is still incomplete, probably has some bugs, needs some refactoring already... but it works in the simple example scenario I have running locally.

    Work will continue daily, so stay tuned!

    Check out the TaskManager:
