JSFoo 2012

It’s like kung fu with JavaScript and objects! All about building full size apps in JavaScript.

About JSFoo

JSFoo is India's only national JavaScript conference series, with editions in Bangalore, Pune and Chennai. This year's Bangalore edition is a flagship two day event.

Event theme

The theme for this second edition in Bangalore is JavaScript everywhere. Tell us how you're pushing the limits of what can be done with JavaScript on the server, in embedded devices, and in its original home in the browser. If you have built something that is popular (even if proprietary), tell us the story of how you did it. Got graying hair? Help us younger folk attain the zen of JS. Tell us about best practices in code and in working style, of how to organize our files and how to assemble crack JS teams.

Commitment to open source

HasGeek believes in open source as the binding force of our community. If you are describing a piece of technology, we'd like it to be available under a permissive open source license.

If your software is commercially licensed or available under a combination of commercial and restrictive open source licenses (such as the various forms of the GPL), please consider picking up a sponsorship. We recognize that there are valid reasons for commercial licensing, but ask that you support us in return for giving you an audience. Your session will be marked on the schedule as a sponsored session.

Speaking submissions

You can submit a proposal to speak at JSFoo via the submission funnel below. Please describe your proposal in as much detail as possible. Detail is important if you'd like to be voted up into the schedule. In particular, we want to hear why you are the best person to be delivering a talk on your proposed topic.

Your submission will be up for public voting for up to a month before the event. For the final tally, we will only consider votes from ticket holders, as a way to ensure participants get exactly what they pay for.

This event also has a Program Committee of selected individuals from the community whose votes have additional weight, and whose charge is to help you refine your proposal and prepare it for the event. The Program Committee is responsible for ensuring that the final schedule meets the high quality standards that participants expect.

Making a funnel submission does not guarantee final selection. Selected speakers will get a free ticket to both days of the event (limited to one speaker per proposal). Proposers whose talks are not on the final schedule will be able to purchase tickets at the prevailing rate for the day on which they made their proposal.

Cross platform native apps using ONLY "Javascript" using Titanium

Submitted Aug 1, 2012

  • How Does Appcelerator Titanium Mobile Work?
  • When to use Hybrid solution to create Mobile apps?
  • Myths about Mobile Apps?
  • What you should forgot to Work with Titanium?

Outline

Titanium takes your Javascript code, analyses and preprocesses it and then pre-compiles it into a set of symbols that are resolved based on your applications uses of Titanium APIs. From this symbol hierarchy we can build a symbol dependency matrix that maps to the underlying Titanium library symbols to understand which APIs (and related dependencies, frameworks, etc) specifically your app needs. I’m using the word symbol in a semi-generic way since it’s a little different based on the language. In iPhone, the symbol maps to a true C symbol that ultimately maps to a compiled .o file that has been compiled for ARM/i386 architectures. For Java, well, it’s more or less a .class file, etc. Once the front end can understand your dependency matrix, we then invoke the SDK compiler (i.e. GCC for iPhone, Java for Android) to then compile your application into the final native binary.

So, a simple way to think about it is that your JS code is compiled almost one to one into the representative symbols in nativeland. There’s still an interpreter running in interpreted mode otherwise things like dynamic code wouldn’t work. However, its much faster, much more compact and it’s about as close to pure native mapping as you can get.

Speaker bio

I am front end engineer from Cleartrip. Currently working on mobile apps for cleartrip. My previous experience was with creating hybrid mobile apps. Have worked on more than 20 hybrid apps.
