##About JSFoo
JSFoo is India’s premier JavaScript conference. We launched JSFoo in 2011 as India’s first JavaScript conference. The JS community in India has grown phenomenally since. JavaScript now pervades every aspect of web development – browsers, apps, front-end, backend, mobile, and IoT.
##JSFoo 2016: Theme
Over the last few years, JavaScript has evolved to become the centerpiece of a complex web stack. Today, it is a prime subject of the obsession that lies with performance and speed. How can you get pages to load faster? How do you work with browser constraints to enhance speed? How do you measure performance? What actually is performance? In what ways do faster response times influence your architecture choices and plans? How is this new focus on faster page loads and apps working offline influencing the development of front-ends and backends as well as server side JS?
The theme for the 2016 edition is tackling speed and performance for JavaScript.
We are inviting full talks (40 mins), crisp talks (15 mins + 5 mins Q&A), and 3-6 hour long (hands-on) workshops from practitioners on the overall theme of speed and performance, including the following topics:
- Architecting for performance – case studies on how you got faster response times
- Best practices: debugging and profiling on the web, measuring performance
- Handling large volumes of data in the browser
- Building and deploying web apps eg webpack, travis
- Modern web technology: Angular 2, React
- Universal JavaScript: meteor js
- Progressive Web Apps
- JS off the web – raspberry pi, IoT
- The cutting edge: elm
This year, JSFoo will feature two days of talks on JavaScript (15-16 September) and a single day of talks on design (17 September) at Meta Refresh (call for proposals will open shortly).
Guidelines for submission #
Every proposal MUST be accompanied by:
- A three minute preview video where the proposer gives an elevator pitch about the talk.
- Detailed outline of the talk – either in the form of draft slides, mind map and/or textual description.
- If you are proposing to speak on a topic where the code is not open-sourced yet, the editorial panel will consider your proposal only if the code is made open-source at least three weeks before the conference.
Without the above information, your proposal will not be considered for review.
If you are submitting a Workshop Proposal, you must clearly state:
- Background knowledge that participants must possess in order to attend your workshop.
- Details and links to software / packages which participants must install before coming to the workshop.
- Laptop configuration.
- Links to background reading material and GitHub repos.
- Duration of the workshop.
- Maximum number of participants who can attend your workshop.
- Instructor’s past experience with conducting workshops.
There is only one speaker per session. Workshops can have two or more instructors.
Entry is free for selected speakers.
Due to budgetary constraints, we prefer speakers closer to home. But if we think you stand out, we’ll provide a grant to cover part of your travel and accommodation to Bangalore. Grants are limited and are made available to speakers delivering full sessions (40 minutes or longer) only.
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.

Web performance case study: the making of abof.com
Submitted Aug 15, 2016
Section:
Full talk
Technical level:
Intermediate
A from-the-trenches narrative about how the fastest e-commerce website in India was built. Starring React, Redux, Webpack, and a whole lot of discipline.
Outline #
Earlier this year, the folks at Aditya Birla Online Fashion commisioned a rewrite of their web front-end from scratch. The goal of the rewrite was to improve page speed – and hence conversion rates – on mobile devices. The first stage of the rewrite was carried out over a period of three months and, on launch day, the load times for the product listing pages on https://www.abof.com were the lowest among all the major e-commerce websites in India, even on the cheapest white-label Android devices on flaky 3G/2G connections.
My talk is a from-the-trenches narrative about how the Alaris Prime[1] and ActiveSphere[2] teams accomplished this feat, going into detail about our technology choices, build tooling, processes, and testing methodologies.
Along the way, I will touch on the key factors that affect web performance, the state of the front-end ecosystem, ReactJS and its ecosystem, ServiceWorkers and progressive web applications, and the importance of build tooling and automation while building front-end applications.
Building performant web applications isn’t hard, but it requires discipline. My goal is to decompose the philosophy and thought processes that lead to great webapps into a set of guidelines that tech teams can follow to replicate what we did at abof in their own workplaces.
The content and structure of the talk will roughly follow the series of blog posts we at Alaris Prime published on our blog recently. You can read the first part here: https://blog.alarisprime.com/e-commerce-case-study-building-faster-listing-pages-on-abof-com-part-1-cb99231a1e8a. Follow us to read the second and third parts of the case study as they are published!
Requirements #
- A solid understanding of HTML, JavaScript, and CSS.
- Experience with building web applications using any one of the popular front-end frameworks (Backbone, Angular, React, Ember, etc.)
- Experience with debugging web applications using the Chrome Dev Tools.
- Basic knowledge of how REST APIs, CDNs, and task automation works.
