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.

Building ideal applications in a practical world.

Submitted Aug 15, 2016

The talk is a quick walkthrough in some of the problems we (EdGE Networks) face while building a product.

We’ll talk about some tools such as:

  1. Is Angular 1.x really that bad?
  2. How to get comfortable with React and move on to build complex apps with it.
  3. Gulp or Webpack (or do you even need them?)
  4. Chrome Dev Tools

but I would like to emphasize on reasons behind using them, rather than the tool itself.



The talk will consist of certain tools being used in acheiving each of these steps, but I would like to
emphasize on the reason to take each of these steps rather than the tools that helped in acheiving it.

Since tools will always get better, its important to focus on the reason why you choose
a certain approach.

Following is the gist of the talk:
It’s a quick walkthrough of how we (EdGE Networks) started developing an app and some of decision we’ve
taken since then.

  1. Getting it done! - building applications with Angular 1.x
  2. Optimizing the application - Chrome Dev tools, creating builds (Gulp), cleaning up some Angular code.
  3. Making a decision - Should we re-write the app?
  4. React + Redux is a great, but.... what about the learning curve?
  5. Components (as opposed to the entire app) are easier to reason with.
  6. Scaffolding for Designers and Developers to design, develop and test components.
  7. Benefits of the component approach (one such benifit being): Components request state via a Middleware, this abstracts requesting state from how its obtained, one of the benifits being state reuse.
  8. Creating reusable components.

Will soon be sharing the code on Github! Thanks!

Speaker bio

While submitting the form, this field mentioned Tell us why you are the best person to be taking this session

I’m definitely not the best person to take this session, but I’m passionate about engineering.
The talk is about our (EdGE Network’s) journey in building a better product.

I enjoy Software development and all the nuances about it :)

Although not stricly JS related, some of the things I’d love to discuss about

  1. ClojureScript
  2. RxJS
  3. Ampersand.js
  4. Event Sourcing
  5. AWS
  6. Spark
  7. Capturing app metrics
  8. Application architecture
