##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.
Important dates:
Deadline for submitting proposals: 29 August 2015
Conference dates: 15-16 September
##Venue
JSFoo will be held at the MLR Convention Centre, J P Nagar.

Handling performance for Progressive Web Apps at scale: Flipkart
Submitted Aug 18, 2016
Section:
Full talk
Technical level:
Intermediate
At Flipkart, we are in the process of rolling out our new desktop website. This has been built entirely from scratch on a new tech stack, rethinking many best practices. On the performance front, we have made multi-fold improvements in almost all key metrics. Carrying forward the learnings from our work on Flipkart Lite, the new desktop site is also built as a progressive web app with similar capabilities. But there are many key differences in building desktop and mobile sites. The browser ecosystem is vastly different, user behaviours, device capabilities and SEO requirements to name a few.
Solving for the best user experience, while keeping performance as a high-priority requirement and implementing PWA-like features turned out to be a very interesting problem statement.
In this talk, I’ll be focussing on how we are scaling progressive web apps at Flipkart and improving performance at the same time. I’d also like to talk about how business and performance tracking needs to change when you move from a server-rendered website to a client-side single-page app. Traffic monitoring, real-time perf monitoring and user monitoring are key, and what metrics can indicate success or as early warnings for potential issues.

Speaker bio
I have been working with Flipkart since the last 4 years, and have seen multiple technology and stack changes. Having lead two such web projects (Flipkart Lite and now the desktop website) along with a great team, I feel there’s a lot we have learnt over this period, and would love to share our experience with the community and give a little back.
