Native Bridge

React Native Bridge for iOS and Android

Mahesh Bokhani

Last Updated on February 15, 2022

React Native is combined with iOS and Android. We can create a React Native bridge between the Native languages like Java, Kotlin, Objective-c, Swift, and JavaScript code. Here bridge means the communication between the native platform and React Native.

Table of Contents

1. Define Native Modules

2. Native Bridge component

  • React Native Bridge Android
  • React Native Bridge iOS

In this blog post, we will discuss React Native Bridge for both iOS and Android.

Define Native Modules

Native modules are distributed as npm packages, except that on top of the usual Javascript, they will include some native code per platform. To understand more about npm packages, please go through this useful Guide.

Native Module Steps:

Let’s understand the native modules with examples.

Create the Exit App

We will create an ExitApp demo using react-native CLI. In this example, button press to exit the app using the native language.

react native init

Hopefully, your project runs successfully.

Native Bridge component

React Native Bridge component is the handy tool for React Native Developer to bridge the native component.

1. React Native Bridge Android

Create a new java class, ExitModule, and ExitModulePackage.

ExitModule.java

⦿android/app/src/main/java/com/exitapp/ExitModule.java

So it is a class that extends ReactContextBaseJavaModule.

ReactContextBaseJavaModule implements a method getName that returns a string. getName() in string name, which we will refer to the native module in our Javascript code.

@ReactMethod java method should be annotated to expose a method to JavaScript. Multiple @ReactMethod methods can be created in this class.

ReactMethod

ExitPackage.java

⦿android/app/src/main/java/com/exitapp/ExitPackage.java

So it is a class that extends ReactPackage.

Registering new JS modules that can be accessed from native modules or from other parts.

The native code requires JS modules from the package that doesn’t automatically be included as a part of the JS bundle, so there should be a corresponding piece of code on the JS side that will require the implementation of that JS module so that it gets bundled.

implementation of that JS

MainApplication.java

⦿android/app/src/main/java/com/exitapp/MainApplication.java

ExitPackage add in MainApplication.java

ExitPackage add in MainApplication

Are you looking to create attractive UI components using react native JavaScrip code?

2. React Native Bridge iOS

Create new file ExitModule in Xcode File/New/File/Cocoa Touch Class

React Native Bridge iOS

ExitModule.h

⦿ios/ExitApp/ExitModule.h
ios/ExitApp/

RCTBridgeModule use in native land to talk with React Native

ExitModule.m

⦿ios/ExitApp/ExitModule.m

React Native will not expose any methods of ExitApp to JavaScript unless explicitly told to. This is done using the RCT_EXPORT_METHOD() macro:

 RCT_EXPORT_METHOD

Your class must also include the RCT_EXPORT_MODULE() macro. RCT is the short name for React and includes it in your Objective-C code.

RCT_EXPORT_METHOD supports this standard JSON object types:

  • NSString (string)
  • NSInteger, float, double, CGFloat, NSNumber(number)
  • BOOL, NSNumber(boolean)
  • NSArray (array)
  • NSDictionary (object)
  • RCTResponseSenderBlock (function)

Finally, Android and iOS side native code are completed. So ExitApp calls in react-native in a javascript file.

NativeModule.js

NativeModule.js

App.js

App.js

OutPut:

Now run the app

Now run the app
