CI setup for a new React Native project is a tedious trial&error process. Let’s talk about how we can make it simpler.

Toss, South Korea’s leading fintech app, runs 40+ micro React Native apps inside a brownfield super-app with 20+ daily deployments. We’ll share how we customized the bundling pipeline—replacing Metro with esbuild and enabling dynamic multi-bundle loading—to achieve sub-10s builds, sub-200KB bundles, and scalable React Native deployments at scale.

Explore best-practices to help you get the most out of over-the-air updates with EAS Update. Learn how to build preview deployments into your continuous integration and testing workflow, and see how to leverage the expo-updates JS API to ensure users receive your updates as soon as possible.

This session will explore how the 2024 updates streamline development processes, enhance performance, and expand compatibility with various platforms, making it an indispensable tool for developers. We'll demonstrate how Expo's improved hot reloading, increased access to native APIs, and superior debugging tools simplify the creation of complex applications.
