A behind-the-scenes look at how we unified iOS, Android, and Web development using React Native Web. We'll cover the challenges that led us to adopt a single codebase, the business and engineering benefits we've seen, how our development workflow supports all three platforms, and the lessons learned from building and scaling a cross-platform product in production.

In this talk, I’m diving deep into how to build universal libraries that work on all platforms – a React Native first approach that works everywhere including the browsers! Together, we’ll explore the nitty-gritty challenges and innovative solutions associated with creating tools that seamlessly bridge the gap between web and mobile platforms. Expect a concoction of creativity, practicality, and actionable insights as we journey from idea to implementation.

React Native is increasingly supporting the web platform. From libraries to routing patterns, everything is moving toward a more unified approach to creating user interfaces for both web and mobile at the same time. But what is the real cost of trying to achieve this, and is it the right direction overall?

In this talk we will examine the state of deploying web apps with React Native web. To meet modern standards, we will use NextJS to deploy to web and Expo to build the native app. In addition, we will take a look how much code can be shared between these two platforms and how easily set a project up.

We will also take a look at cross platform component libraries and libraries that you will be using along the way.
This setup is great for any dev who wants to deploy to multiple platforms, but only wants to write his code once.
