Truly Cross-Platform React Native

Submitted Jan 31, 2019

At Flipkart, we have been using React Native for more than 2 years now. Though React Native allows us to build Apps that run on Android and iOS, we wanted to explore whether it was possible to make truly cross platform apps which will run on Android, iOS, mobile web and desktop. Could React Native scale to all form factors and not just run on mobile handsets?
Needless to say, we were able to build and ship multiple features on aforementioned platforms. This talk will walk you through the questions we asked ourselves while we were approaching problems like these, how we mitigated them and then made our features available to millions of our users. It should serve as a guide for others trying to solve similar problems and how they could piggy bank on our experiences.


We will be addressing the following questions:

React Native solves for android and ios but can it solve for mWeb?
What is react native web?
If mobile web is possible, is desktop possible as well?
What about design problems on desktop?
Can react native solve for animations?
Can those animations work equally performant on Web?
How to do animations? How to use svg’s?
Can the same animations work on web?
What about the bundle size on web for react native pages?
Can we do bundle chunking in these pages?
Can Native Modules exist on web?

Lastly, we will talk about 2 games that we recently launched on the Flipkart Gaming Platform which saw more than 40 Million gameplays across India.

A React Native widgetised framework - Move fast and build things.

We have already seen how React Native and React Native for Web helped us in building full-fledged features on all platforms such as Android, iOS and the web. After solving this problem of code sharing, the next one we are headed to is solving the case of custom layouts. For instance, an e-commerce product page could have different UI layouts for a shirt, a sofa, and a mobile, though their basic b… more
