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

Venue

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

Advanced State Management With Redux

Submitted Aug 15, 2016

A talk covering advanced patterns and common state-management scenarios in a Redux-powered application.

Outline

Redux is the best. It’s better than Rihanna’s new album, better than Pokémon Go, and better than Obama’s summer playlist.

Actually, I lied. Nothing is better than Rihanna’s new album. But if you’ve ever written a reasonably complex React application, you know that state management is a pain in the butt and that Redux makes all the pain and complexity go away, which makes it at least second best.

However, adding Redux to your app often raises a ton of questions that are not always answered in the documentation.

  • How do I reduce boilerplate when writing my reducers?
  • Should I normalize the data I receive from my REST API before putting it in my store? Why? Why not?
  • If I normalize my data, I have a hard time querying it before I pass it to my components. What do?
  • How does Redux work with localStorage? HTML5 history?
  • I’m trying to add a feature to my app that requires 5 API calls, each one depending on the result of the previous call. What’s the best way of expressing this workflow with Redux?
  • How do I handle and keep track of server errors? Form errors? Global notifications?
  • What is a Redux middleware? How do I write one?
  • What is a store enhancer? How do I write one?
  • What’s the best song on ANTI and why is it Work?

This talk aims to address common Redux questions, best practices, and pitfalls. I’ll demonstrate working code examples, explain why things work the way they do, and throw in a couple of Kanye West memes for free.

Requirements

  • A solid understanding of JavaScript.
  • Experience with building front-end applications using React.
  • Experience with using a state management library with React (Redux, MobX, or any implementation of Flux).

Speaker bio

Ankur takes selfies, listens to way too much hip-hop, and writes JavaScript at Alaris Prime.

He has worked on everything from filesystems to mobile games, but his first love has always been the web platform.

In the past, Ankur has built complex JavaScript applications for Insider.in, Understanding Limited, and Aditya Birla Online Fashion, among others.
