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.

Format

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 single page apps with React.JS

Submitted Aug 29, 2014

Participants would understand how ReactJS works and how to build a single page app with ReactJS. We will also briefly touch upon the Flux application architecture and see how we can architect applications with the Flux architecture

Outline

ReactJS helps us build Reactive UIs with javascript. It was built by Facebook and is used by open source editors like Atom. ReactJS builds a Virtual DOM instead of using Browser’s DOM that allows Single Page Apps to run at 50fps even on mobile browsers. This also simplifies the View code as there is no need to track the state of the DOM and can simply re-render the view without affecting the performance.

The workshop will be structured into three parts. The first and third part will talk about the state of React and its path going forward and the meat of the workshop would be a hands on approach in building a Todo List app using a parse backend and the UI built with React.JS and Backbone.

  • A quick intro to React.JS and JSX
  • Build a todolist app with React.JS and Backbone
  • A quick intro to Flux and upcoming projects like React Router similar projects like HTMLBars

Speaker bio

I have been building apps for the past 10 years with various technologies like Clojure, Ruby, Node, Python and Java. Both libraries like jQuery and frameworks like BackboneJS, Ember, Angular have left me wanting with a better way to build large apps. Having worked with ClojureScript and Om, I beleive that ClojureScript with frameworks like Om/Reagent is probably the best way to organize large frontend codebase.
