JSFoo 2016

Tackling speed and performance for JavaScript

##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

JSFoo will be held at the MLR Convention Centre, J P Nagar.

High performance Desktop applications with Electron (Javascript framework)

Submitted Jul 27, 2016

Electron is a javascript framework from Github, to build powerful cross platform desktop applications with HTML/JS/CSS. On top of electron, imagine applications developed with existing javascript ecosystem and building desktop apps - the outcome will be amazing. During this session, we will discuss in detail from a performance perspective, how we can analyze electron applications and how we can solve different challenges involved in it. With this stack, we can solve complex computation problems (data analytics, image processing) using javascript stack to achieve quicker load time and computation time.


Following is the mind map of the session flow.
First 10 minutes ->

  • introduction to electron & key features
  • how Javascript based desktop application development could be helpful
  • Demo of a small hello world application and showcase how easy it is to get started
  • Tools for rapid application development (debugging)

Second 10 minutes ->

  • quick look into applications developed using electron
  • discuss different kind of problems we can solve
  • performance benefits with this stack
  • bringing in performance improvement on NodeJS level
  • bringing in performance improvement on JS level
  • bringing in performance improvement on V8 engine level

Third 10 minutes ->

  • demo performance intensive application
  • showcase how to do performance analysis
  • showcase optimisation techniques
  • showcase performance improvement
  • how to apply the earlier discussed techniques to solve perf problems
  • challenges in desktop applications

Fourth 10 minutes ->

  • Conclusion notes
  • Followup resources - Github project links
  • Question and answers

Speaker bio

I am Sairam Krish. I am a passionate developer for the past 12 years. I have been working on Electron based desktop applications and found it to be very impressive, in solving regular challenges with desktop applications. Also it bridges the gap between desktop and web applications. I like to share my actual work experience, findings and learning with the community. I have presented the same topic inside the company and response was amazing. Like to present it in JSFoo, since, we will have best Javascript audience.
