Java React Native

Native Module Setup​ Directly within your React Native application’s iOS/Android projects. As a NPM package that can be installed as a dependency by your/other React Native applications .

A native module is a set of javascript functions that are implemented natively for each platform (in our case is iOS and Android). It is used in cases where native capabilities are needed, that react native doesn’t have a corresponding module yet, or when the native performance is better.

With React Native, you create one codebase that works on both Android and iOS . And it doesn’t just “work”—it compiles to native Java and Swift code. Specifically, React Native creates a bridge between web UI components and their native Java/Swift counterparts.

The Bridge in React Native permits the JavaScript code and the Native code to interact with each other . Without the bridge in React Native, there is absolutely no means for the native code to transmit any information to the JavaScript code and vise versa.
