Commitment to Open Source

HasGeek believes in open source as the binding force of our community. If you are describing a codebase for developers to work with, 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.


If you are interested in conducting a hands-on session on any of the topics falling under the themes described above, please submit a proposal under the workshops section. We also need you to tell us about your past experience in teaching and/or conducting workshops.

BOF sessions

If you are interested in doing an unconference during the breakout sessions, propose a topic which will be of interest to the community.

Important dates:

Deadline for submitting proposals: 31 July 2015
Conference dates: 18-19 September
Workshops: 15, 16, 17 and 20 September

JavaScript Plugin Architecture for Single Page Applications

Submitted Sep 11, 2015

Learn architecture of a third party integration capability in QBO and implementation aspects like same origin policy limitations handling with easyXDM.


Web Applications have become increasingly complex – and it is very common to have applications that require interaction with third-party applications. On the other hand, our end users like to have a single place for all these interactions. This suggests the need for composing a webpage from multiple independent applications while at the same providing a unified user interaction model. Our team has developed a JavaScript based Plugin Architecture for Intuit’s QuickBooks Online (QBO) that enables this. We will share our experiences and learnings in building this. We talk about different approaches to integration, architectural/design principles underlying our implementation and user facing (and experience related) aspects of a good integration. We discuss design details such as access, attach points etc., usage of easyXDM to circumvent same origin policy limitations, sandboxing plugins and experimentation framework.
