This presentation will explore Code Push's latest version, its role in the Mobile Center's DevOps suite tailored for React Native, and how it streamlines the process from code commits to app distribution, while also enhancing app quality through crash monitoring and analytics.

Gain insights into the current state of React Native after nearly 5 years of development. Explore its internals and upcoming architectural changes, including its compatibility with React Fiber.

Explore performance optimization in React Native, addressing the potential cost of control transfer between layers. This talk delves into tips and tricks to maximize React Native's performance attributes. It begins by instrumenting a sample app across JavaScript, Java/ObjC, and C++ layers. The talk then demonstrates how this data can enhance specific rendering processes. It concludes by integrating these performance practices into the CI system for consistently smooth and fast React Native apps.
