JSFoo 2014

JavaScript as the centerpiece of a complex web stack

In 2011, Node.js put JavaScript firmly in the backend, making JavaScript developers productive at both ends of the stack, and making it possible for business logic to finally be moved into JavaScript.

In 2012, AngularJS made us think about moving business logic completely into the client-side as an actually sensible idea. Meteor give that idea two thumbs up.

In 2013, we went wild thinking of all the possibilities. JavaScript phones! Robots!

In 2014, it’s time for some sobering up. The backends we built over a decade in Ruby and Python aren’t going away. New languages like Go and Hack are tantalising us with new possibilities. Our applications are increasingly distributed, often involving third party APIs. In such a scenario, where does your business logic reside?

In 2014, JavaScript is no longer a toothless child or a rebellious teenager that wants to do everything itself. JSFoo 2014 is about working with JavaScript as the centerpiece of a complex web stack.


This year’s edition spans four days, with two days of workshops and two days of conference. All days feature a single track. We invite proposals for:

  • Full-length 40 minute talks
  • A crisp 15-minute presentation
  • Sponsored sessions, 40 minute duration
  • Flash talks of 5 minutes duration. Submissions for flash talks will be accepted during the event
  • Three hour workshops where everybody gets their laptop out and follows along

Criteria to submit

You must be a practising web developer or designer, and must be able to show how your own work has advanced the state of the web in the past year. You are expected to present original work that your peers — this event’s audience — recognise as being notable enough to deserve a stage.

If you are excited about someone’s work and believe it deserves wider recognition, we recommend you contact them and ask them to submit a proposal.

Selection Process

Voting is open to attendees who have purchased event tickets. If there is a proposal you find notable, please vote for it and leave a comment to initiate discussions. Your vote will be reflected immediately, but will be counted towards selections only if you purchase a ticket.

Proposers must submit presentation drafts as part of the selection process to ensure that the talk is in line with the original proposal, and to help the editorial panel build a strong line-up for the event.

There is only one speaker per session. Entry is free for selected speakers. HasGeek will cover your travel to and accommodation in Bangalore from anywhere in the world for speakers delivering full sessions (30 minutes or longer). As our budget is limited, we will prefer speakers from locations closer home, but will do our best to cover for anyone exceptional. If you are able to raise support for your trip, we will count that as speaker travel sponsorship.

If your proposal is not accepted, you can buy a ticket at the same rate as was available on the day you proposed. We’ll send you a code.

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.

Building realtime web applications that live update when other people make changes

Submitted Aug 8, 2014

To show you how a best-practice combination of the latest javascript technologies brought together into a clean cohesive solution that accomplishes pure awesome.

Usually this is a pretty messy accomplishment, or just has old-generation tech stuck together with newer tech, or people using buzz word projects rather than what actually makes sense. This talk will cover why this select stack works so well for this, keeps complexity down low, keeps the codebase beautiful, and how others were tried for this and didn’t make sense.

Expect to:

  • Understand the complexities of building realtime applications, and how they can be avoided
  • Understand the complexities of building node.js applications, and how they can be avoided
  • Understand the complexities of building frontend applications, and how they can be best addressed
  • Learn best practices for building realtime web applications, why they are important, and what you can use for them


Over the past 8 weeks I was contracted to build and innovative app, and began re-evaluating the best tech and practices that is out there, and become a student again to try a bunch of things. Over this time I evaulated pretty much everything there is, and came up with the following stack, which will include comparisons with other projects for each part.

It works really well. We’re seeking permission to demo the app we built, however if this talk gets accepted we’ll also begin work on an open-source project that uses the same tech with a lot of documentation for you all to try and work with.


The talk will be ascessible to everyone, with everyone getting learnings. Those which have done javascript and/or frontend development for a while will be able to appreciate the depth of learnings in it as they will be able to relate the pain and pleasures to their own experiences.

Speaker bio

Benjamin’s calling in life to empower everyone to do what they love, share it with the entire world, and live well. His work is used by pretty much everyone (Microsoft, Adobe, GitHub, etc), and is one of the most active github users in the world. The past year he’s been working with Polymer (Web Components) and WebRTC to build some interesting things, and before that he worked on DocPad (the most popular node.js static site generator) for 3 years and built History.js (cross-browser support for stateful web applications) which has gone on to be very popular. These days he’s still with open-source and looking into trainings.
