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.

Glueing application components with Javascript

Submitted Aug 3, 2012

  • To embed JavaScript in Network and Desktop application components, specifically the JVM
  • Modularity and robustness of the applications
  • Giving users the power to script new features into the applications


JavaScript is a nice little language with awesome features that make it easy to learn and code in. Rather than hard-coding all the components of a software into a single language bundle, we can compartmentalize and put the core application logic in one of the mainstream languages and implement the user interfaces and API calls in JavaScript.

In this talk I will speak about embedding Javascript specifically on the JVM, and similarly it can be implemented in other languages like C++. The focus will be on Java’s Scripting API and Mozilla Rhino to write software components in Java and glue them with JavaScript. This will make the application components more modular and we can write easily updatable application reducing the compilation overheads. It can be used to create Javascript bindings to underlying Java code.

I will speak on how to expose simple API in your applications for end users to create scripts to customise and extend its functionality. Here I will take up one of my self made applications - a media file format converter to demonstrate how simple scripts written by the user can leverage the power of the app and to do batch processing and other actions, by using its API.

Speaker bio

I am currently a student of IIT Rajasthan, in my second year. I have been using Java and JavaScript since my school days to make applications and webpages. Have also contributed a few patches to Mozilla Firefox.
