Building high performance local-first apps with Legend State

Jay Meistrich - Founder @ Legend & Creator of LegendState

This workshop helps you look at common performance problems in React and React Native, and teaches you how to fix them. You will explore the architectural differences between local-first apps and server-driven apps, and what makes local-first hard. Then you will dive into how Legend State makes performance and local-first easy, and the best practices for achieving the best performance and a robust sync system with less code.

Web, Mobile, and API, All Together: Universal Full Stack Apps in Expo Router

Keith Kurak - Developer Success Engineer @ Expo

Expo Router, the first file system-based router for universal React apps, lets Android and iOS apps take advantage of expressive and powerful routing features previously only available to web developers. Your folder and file structure represent your app navigation, while dynamic routes let you pattern match multiple routes to a single page, creating intuitive nested URL's that automatically work as deep links on mobile. Expo Router also makes it easier to target web and mobile, and even frontend and backend in one project, with features like headless navigators and API routes. Let's take a tour of what Expo Router offers for universal React apps, starting with basic and dynamic routing, to adding features like authentication routing, backend routes, and dynamic navigation layouts.

Mixing Native & Web Projects within a Monorepo: Learn to Share Logic and Components.

Thibault Malbranche - Lead Mobile Developer @ Brigad & React Native Core Contributor

Combining native & web projects often comes with practical challenges. What do you share? What do you not share? Let's dive into the challenges to understand how to address the various problems you'll encounter. Let's talk dependency resolution, platform specific implementation & type safety. We will then build a components and utils library leveraging platform-specific features in React Native & React-Dom. If you want to learn how to create universal apps in practice, this is the workshop for you!

Debugging Performance Issues in React Native Apps

Alex Moureaux - Performance SME @ Theodo Apps & Creator of Flashlight

Performance is still the #1 challenge that people face in React Native. We'll start with a custom-built dummy app filled with the typical performance bottlenecks you'll find in your everyday React Native apps. Our goal is simple: measure, analyse, and fix those pesky issues! Together, we'll learn how to use a variety of tools (including React DevTools, Flashlight, JS profiler, Android Studio) and work through each problem one by one to improve the performance of the dummy app. You’ll walk away with a clear, actionable methodology to apply in your own apps to optimise your performance and make your React Native apps buttery smooth.
