Blurbs or blog posts covering the relevance of a particular problem statement and how it is tackled will help the Editorial Panel better judge your proposals. We might contact you to ask if you’d like to repost your content on the official conference blog.

We expect you to submit an outline of your proposed talk – either in the form of a mind map or a text document or draft slides within two weeks of submitting your proposal.

Selection Process Flowchart

You can check back on this page for the status of your proposal. We will notify you if we either move your proposal to the next round or if we reject it. Selected speakers must participate in one or two rounds of rehearsals before the conference. This is mandatory and helps you to prepare well for the conference.

A speaker is NOT confirmed a slot unless we explicitly mention so in an email or over any other medium of communication.

There is only one speaker per session. Entry is free for selected speakers. As our budget is limited, we prefer speakers from locations closer home, but will do our best to cover for anyone exceptional. HasGeek provides these limited grants where applicable: two international travel and accommodation grants, three domestic travel and accommodation grants. Grants are limited and made available to speakers delivering full sessions (40 minutes or longer). Speaker travel grants will be given in order of preference to students, women, persons of non-binary genders, and individuals for Asia and Africa first.

Testing: Testing tools and strategies; test driven development and testing culture; continuous integration and testing workflows; and case studies around testing your application.

Performance optimization: Performance analysis tools and techniques; best practices for building performant applications; browser, NodeJS, and framework internals; network protocols; and performance case studies.

Debugging: Tools for locating and fixing bugs in JavaScript applications; real world post-mortems of bugs that affected your organization; and using telemetry for debugging.

Immutability, type checking, and alternative programming languages: Alternatives to vanilla JavaScript; functional programming and immutability; types and type systems; and real-world case studies of introducing alternative programming languages and tools in your organization.

Build tooling: Build tools and automation, including task runners, linters, JavaScript bundlers, CSS pre- and post-processors, continuous integration tools, static analysis tools, and optimization tools.

Crash and performance monitoring: Monitoring applications for crashes and performance issues while in production.

##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 for it to be available under a permissive open source licence. If your software is commercially licensed or available under a combination of commercial and restrictive open source licences (such as the various forms of the GPL), please consider picking up a sponsorship. We recognise 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”.

Building Immersive Virtual Reality experiences quickly with WebVR

Submitted Jun 15, 2017

Have you noticed that the development of Virtual Reality experiences has started a major makeover of the computer industry? I believe that Virtual Reality is going to become a primary platform soon, which will completely change the way we work, play and communicate digitally.

The Web, being the most open platform, is now a key participant for providing cool Virtual Reality experiences quickly. I want to propose a workshop about Building Virtual Reality websites using A-Frame in this version of JSFoo. A-Frame is an open-source web framework by Mozilla for easily creating VR experiences using WebVR which work on all platforms. It’s really easy and fun to work with A-Frame to build a VR website, all you need to get started is a basic knowledge of HTML & JS.

In this workshop, audience will learn to use various concepts & APIs of A-Frame and will be able to create interactive and immersive Virtual Reality experiences on the web. This workshop will also cover how different is A-Frame from any other similar frameworks like ReactVR. I will also introduce how one can get involved with the A-Frame community to contribute in its development.


1. Introduction [10-15 mins]:

  • Introduction of Presentor & participants (with some quick fun ice breaker activity - if time permits)
  • What is Virtual Reality (Introduction to VR & similar terms, and why is this winning our hearts)
  • How one can build VR experiences today (Different options available to build VR experiences + Demos)
  • How is WebVR making a difference (Introduction to WebVR and its initia specs + Demo)
  • Introduction to A-Frame (How A-Frame out throughs all other options to build WebVR scenes today. + Demos)
  • Introduction to A-Frame docs and few tools which can be used while coding.

2. A-Frame hands-on session [40-50 mins]:
We will divide participants into teams to work on set of tasks, whenever required.

  • Task 1 [5 min]: Understanding example VR scenes - Teams/invidividuals to try out above shown demos by themself using available source codes provided to them.
  • Task 2 [15 min]: Build basic VR scene - Each team is given link of 2-3 VR scenes along with the A-Frame concepts required to build those scenes. I will first shown them a demo by building one such scene and them teams will have to try on their own (organizers/volunteers will help teams build the scenes).
  • Talk [5 min]: After above task, once everyone has basic idea of creating basic VR scene. I will present few best practices & tricks - 5 things I learnt about building immersive VR experiences using A-Frame.
  • Task 3 [15 min]: Time to bring your creativity on screen - Each team to think of interesting VR scenes and create it by applying all your learnings.

3. Q/A & Followup tasks [10-15 mins]:

  • Next steps you can take for building VR experiences.
  • Sharing your experience with A-Frame.
  • Q/A session.
  • Introduction to A-Frame & WebVR community in India.
  • How can you participate to A-Frame library or other Mozilla products.


  1. A laptop/computer (with net connectivity) for coding.
  2. A mobile phone and a VR device for testing the VR experiences built.

We need VR Devices (Cardboards / Daydream View / HTC Vives) to test the VR experiences build by audience. We can make few devices available for all participants, additionally we can ask participants to get their own devices with themself.
