react-native-create-bridge

Bridging native modules & UI components made easy! If you're a JavaScript developer writing your first lines of native code or a more experienced developer looking to eliminate boilerplate from your React Native workflow, this tool is for you.

Getting Started

1. npm install --save react-native-create-bridge or yarn add react-native-create-bridge
2. From the root of your React Native project, run react-native new-module
3. The prompts will ask you for:
- Your bridge module name
- Whether you want to create a native module or UI component (or both!)
- The platforms and languages you would like to support. Currently, we default to iOS/Obj-C and Android/Java, but you can also choose iOS/Swift or Android/Kotlin if you prefer.
- The directory where you would like your JS files. If it doesn't exist, we'll create it for you.
4. That's it! 📦 Sit back and we'll deliver your native module for you lightning fast! ⚡️

Next Steps

Depending on your environment, there may be a couple more steps that you have to take. In future versions of react-native-create-bridge, we want to eliminate these steps.

#### Android/Java
- To complete the bridging process, look for MainApplication.java in android/app/src/main/java/com/yourapp
- Add your package to the getPackages function like this:

``
@Override
protected List getPackages() {
return Arrays.asList(
new MainReactPackage(),
new YourModulePackage()
);
}
`
- Import your package at the top: import com.yourapp.yourmodule.YourModulePackage;

#### Android/Kotlin
##### Adding Kotlin support to your project:
- You will need to install the Android Studio 3 preview
- In android/build.gradle, add ext.kotlin_version = '1.1.2-4' to the buildscript and classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version" to your dependencies
- In android/app/build.gradle, add apply plugin: 'kotlin-android' to the top of the file. At the bottom, add compile "org.jetbrains.kotlin:kotlin-stdlib-jre7:$kotlin_version" to your dependencies
- Now, you can convert any Java file to a Kotlin file by navigating to Code > Convert Java file to Kotlin file in the top menu

##### Completing the bridging process:
- If you already followed all the steps above, you can complete the bridging process by looking for MainApplication.kt in android/app/src/main/java/com/yourapp
- Add your package to the getPackages function like this:
`
override fun getPackages(): List {
return Arrays.asList(
MainReactPackage(),
YourModulePackage(),
)
}
`
- Import your package at the top: import com.yourapp.yourmodule.YourModulePackage

#### iOS/Obj-C
- Currently, you will need to add the files manually to your project in Xcode. Right click on the folder with your app name and select Add Files To YourApp. Select the files associated with your module and click Add

#### iOS/Swift
- If this is your first Swift module in your project, you will need to make sure you have a Obj-C bridging header to expose any Obj-C code to Swift. Read Importing Obj-C into Swift to learn more.

Goals


- [x] Delivers bridge module in Obj-C, Swift, Kotlin, & Java
- [x] Compatible with all versions of React Native, including v0.40+
- [x] Split out native UI components & modules into their own templates
- [ ] Config to remove comments for more experienced users
- [ ] Modifies existing project files (AppDelegate.h, MainApplication.java) to complete the bridging process
- [ ] Your feature request could be here! Open up an issue and give us feedback 😊

Setting Up Dev Environment

1. Fork this repo & clone it
2. cd to where you cloned it
3. npm install or yarn
4. After you make changes, link your local package by running npm run package:dev
5. You can now run react-native new-module locally in a React Native project to test your changes
6. npm run test will run the Jest test suite
