Summary

Turbo Native Modules represent an evolution in React Native’s architecture, enhancing performance and simplifying integration by replacing the asynchronous bridge with the JavaScript Interface (JSI) for direct, efficient communication between JavaScript and native code. Implemented in C++, these modules offer type safety, synchronous reconciliation, and cross-platform code sharing, contributing to significant performance optimizations. This tutorial demonstrates creating a custom Turbo Native Module for an Android app using React Native, enabling access to native mobile APIs for retrieving device-specific information such as model, IP address, uptime, battery status, battery level, and Android version. The tutorial covers setting up the development environment, defining a typed JavaScript specification with TypeScript, configuring Codegen tools, implementing native platform code in Kotlin, and integrating the module into the React Native framework. The process underscores the benefits of Turbo Native Modules in improving app performance and maintaining seamless communication between JavaScript and native layers.
