JSFoo 2016

At Flipkart, we are in the process of rolling out our new desktop website. This has been built entirely from scratch on a new tech stack, rethinking many best practices. On the performance front, we have made multi-fold improvements in almost all key metrics. Carrying forward the learnings from our work on Flipkart Lite, the new desktop site is also built as a progressive web app with similar capabilities. But there are many key differences in building desktop and mobile sites. The browser ecosystem is vastly different, user behaviours, device capabilities and SEO requirements to name a few.

Solving for the best user experience, while keeping performance as a high-priority requirement and implementing PWA-like features turned out to be a very interesting problem statement.

In this talk, I’ll be focussing on how we are scaling progressive web apps at Flipkart and improving performance at the same time. I’d also like to talk about how business and performance tracking needs to change when you move from a server-rendered website to a client-side single-page app. Traffic monitoring, real-time perf monitoring and user monitoring are key, and what metrics can indicate success or as early warnings for potential issues.

Speaker bio

I have been working with Flipkart since the last 4 years, and have seen multiple technology and stack changes. Having lead two such web projects (Flipkart Lite and now the desktop website) along with a great team, I feel there’s a lot we have learnt over this period, and would love to share our experience with the community and give a little back.
