  3. Framework specific security concerns
  4. Authentication
  5. Security audits

Besides the main theme, JSFoo will cover the following topics:

  1. Case studies of Vue.js, GraphQL, ReasonML and other framework/language adoption.
  2. Architecture approaches (and case studies) for engineering web apps.
  3. Latest developments in JavaScript and web ecosystem – the cutting edge.
  4. Best practices: debugging and profiling on the web, testing, measuring performance.
  5. JS off the web – conversational UI, raspberry pi, IoT

We are inviting proposals:

  1. Full talks: 40 mins duration
  2. Crisp talk: 20 mins duration
  3. Hands-on workshops of 3 or 6 hour duration
  4. Birds Of Feather (BOF) sessions of 45-60 mins duration

Selection process

Proposals will be filtered and shortlisted by an Editorial Panel.

Make sure to add links to videos / slide decks when submitting proposals. We will not review proposals without detailed outlines or slide decks and preview videos.

The first filter for every proposal is whether the technology or solution you are referring to is open source or not. If you are referring to a proprietary technology, consider picking up a sponsored session.

The criteria for selecting proposals, in the order of importance, are:

  1. Key insight or takeaway: what can you share with participants that will help them in their work and in thinking about the problem?
  2. Structure of the talk and flow of content: a detailed outline helps us understand the focus of the talk, and the clarity of your thought process.
  3. Ability to communicate succinctly, and how you engage with the audience. You must submit link to a two-minute preview video explaining what your talk is about, and what is the key takeaway for the audience.

No one submits the perfect proposal in the first instance. We therefore encourage you to:

  1. Submit your proposal early so that we have more time to iterate if the proposal has potential.
  2. Write to us on: jsfoo.editorial@hasgeek.com if you want to discuss an idea for your proposal, and need help / advice on how to structure it.

Our editorial team also helps potential speakers in refining their talk ideas, and rehearsing at least twice - before the main conference - to sharpen the insights presented in the talk.

Passes and honorarium for speakers:

We pay an honorarium of Rs. 3,000 to each speaker and workshop instructor at the end of their talk/workshop. Confirmed speakers and instructors also get a pass to the conference and networking dinner. We do not provide free passes for speakers’ colleagues and spouses.

Travel grants for outstation speakers:

Travel grants are available for international speakers who have led/worked on projects that have large-scale adoption. Travel grants are available for domestic speakers (without the criteria mentioned for international speakers).
We evaluate each travel grant application on its merits, giving preference to women, people of non-binary gender, and Africans. If you require a grant, request it when you submit your proposal in the field where you add your location. JSFoo is funded through ticket purchases and sponsorships; travel grant budgets vary.

Important dates:

JSFoo + Meta Refresh: 26 and 27 October, at the NIMHANS Convention Centre.

Using Service Workers to improve dynamic image delivery in the browser

Submitted Sep 3, 2018

As mobile data and mobile devices become more and more accessible in India, we need to build experiences not just for the high-end users but also vary our content dynamically to cater to users with slower devices or poor network connectivity. Images being the single largest contributor to page size provide a great, yet simple, opportunity to optimize for a faster experience to all the users.

Key Takeaways
- Using service workers to dynamically adapt image content on a web page on the basis of network speed
- Important points to consider while using this technique
- An inexpensive way to achieve capabilities that are usually restricted to expensive infrastructure providers

Intended Audience
- Front-end developers keen on using modern technology to deliver a faster user experience for their website’s users

Outline

  • What is meant by dynamic image delivery
  • Why is it important now and what are the different types on which it can vary.
  • What is network-based dynamic image delivery
  • Why use Service Workers for it?
  • How to use a Service Worker to detect network type / speed
  • How to intercept image requests and modify them on the basis of the detected network speed
  • How to use real-time image transformations using URLs to achieve this
  • Caching of modified responses
