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 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?
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
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.
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.
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.
Functional Reactive Programming with RxJS
Web Applications have changed over the year from simple HTML pages to DHTML to Ajax revolutions. Each time, we are adding more complexity to handle asynchronous behaviour of data and events. How do we react to such asynchronous flow of user events and AJAX Data?
RxJS is a set of libraries for composing asynchronous and event-based programs. Every asynchronous data stream (that come from diverse sources, e.g., stock quote, tweets, computer events, web service requests, etc.) and user event stream is represented using the Observer object. Functions can then subscribe to such Observer and gets notified when an event occurs. Once notified, query operations like filter, project, aggregate, compose and time-based operations can be performed on those multiple event data by using RxJS operators.
Cancellation, exceptions, and synchronization are handled gracefully by using the methods on the Observable object.
A synopsis of this talk:
What is Functional Reactive Programming and How RxJS applies it?
Different operations defined in RxJS with examples.
How do we observe and subscribe to events?
An use case example using RxJS.
