Deep Dive Into React Native

Wix Mobile Application is built with React Native, a cross-platform framework, allowing developers to compose mobile apps using JavaScript in a declarative way.
Scaling a production-grade application with such young framework without compromising on performance and dev velocity, forces us to deeply understand the internal architecture of React Native.
In this talk we will start with an overview of the React Native framework, following that we will dive into the main building blocks of the framework such as the Bridge, Native Modules, Metro Bundle and understand what really happens during runtime of our application.
We will focus on the architectural bottlenecks of the system and explain how the upcoming re-architecture of React Native is going to solve these problems.
