JSFoo Coimbatore 2019

On building faster, performant and secure web applications

About JSFoo Coimbatore

JSFoo Coimbatore is a single-day conference with talks, Birds of Feather (BOF) sessions and speaker connect sessions. The conference will be held on Friday, 5 July, at Dr.G.R.Damodaran College of Science, Coimbatore.

JSFoo Coimbatore features talks on:

  1. How to secure your web applications by identifying vulnerabilities.
  2. Leveraging Web Application Vulnerabilities for Resourceful Intelligence Gathering.
  3. Case studies of performance improvements and using the modular approach to building front-ends.
  4. Node.js and good engineering practices such as logging, debugging and integrating security into your applications.
  5. WebSDK: switching between service providers on the fly.

Speakers from Hotstar, Uber, HackerRank, Chained Ventures, Tezify, Appsecco, Gramener, and Centre for Internet and Society (CIS) will present case studies and experiential talks which will help JavaScript, full stack and front-end engineers among partcipants to build faster, secure and performant we applications.

Why aren't you using Async Generators yet?

Submitted Sep 16, 2018

JavaScript has a new underutilized addition: Async Generators, and they’re a great fit in the functional world and they enable a lot of critical patterns when programming to ensure a clean, scalable codebase. I’ll focus on what Async Generators are, how they work under the hood in browsers, Node.js (and even babel) and filled with examples of use cases in production including how async generators play with the upcoming (probably released by ReactFoo) Async React constructs. Finally, I’ll talk about libraries/tools that can help you develop with them more easily. Anyone programming in JavaScript could benefit from this.


  • Explain the 4 constructs (the same grid RxJS uses to explain Observables) in programming: Synchronous single value, Synchronous multiple values, Async single values and the “missing” async multiple values.
  • Iterators
  • Observable
  • Async Iterator
  • Iterator spec (making your own iterators) and built in iterators (like Node.js stream)
  • Generators and async generator
  • Examples of usage and patterns (this is the longest bit as I show you how to use it in cases like polling, incremental updates (especially for updating a React tree as data becomes available))

The rest is time allows (I’ve planned for upto 40m with this talk)

  • A comparison with Observables
  • A quick explanation of how this works under the hood (with a potential explanation of the Babel transform)
  • A few examples with Shiksha (a library that implements map, debounce, pairwise etc. inspired by RxJS)


Some experience using javascript and asynchronous programming (preferably some experience with Promises and a high level understanding of how a Promise works)

Speaker bio

Pranay worked on GraphQL and Relay at Facebook and on core infra and product at ZEIT. He currently studies at the University of Illinois at Urbana Champaign and did his thesis on “Optimising Javascript with Babel” (including a segment on iterators) which inspired him to dive further into async generators and inspired this talk.

GTM - (Google Tag Manager)

Proposal and 5 good reasons why i am recommending exactly this. 1) People should know about event tracking. 2) GTM Takes hassle out-of normal tracking. 3) It also helps to speed up testing of your new website launching using tracking. 4) User tracking and data capturing is very easy with GTM. GTM passes this tags and triggers data to Google analytics and your events get tracked over their. 5) GTM… more
