Discover strategies for building universal apps with React Native that target both mobile and web platforms. This workshop will cover concepts like: routing, styling frameworks, DOM components, testing strategies, and more. We'll answer the question of whether react-strict-dom is ready for production use. In addition, we will use AI to develop skills and tools that make our day-to-day work on cross-platform solutions easier. Learn how to maximize code sharing and build high-quality apps tailored to multiple platforms.

These workshops dive deep into React Native performance, focusing on practical tools and techniques to help you write faster, more efficient React code. You'll learn how to identify bottlenecks, optimize rendering, and take advantage of profiling utilities built into the ecosystem, with additional support from AI-powered workflows. Beyond JavaScript performance, we'll also explore how to detect and diagnose native-level issues that can impact your app's responsiveness, including analyzing profiling traces with the help of AI tools. By the end, you'll have a solid toolkit for diagnosing and fixing issues, using both proven techniques and AI assistance to deliver smoother, more reliable mobile experiences.

The React Native community offers a lot great packages for tapping into native API’s, but every app is unique, and sometimes that means you need to write your own custom native code to interface with JavaScript. The Expo Modules API lets you write native modules with minimal boilerplate while utilizing modern language features, and with a consistent development experience on both Android and iOS. In this workshop, you’ll learn the core concepts of the Expo Modules API, set up your environment from scratch, and build your first modules step by step.
