React-Native Cordova Plugin Adapter

A way to use Cordova plugins in React-Native Applications

Why?

The Cordova plugin ecosystem is diverse and rich. Many native device capabilities are already available as a plugin with a W3C like Javascript API in most cases. Using them to access native capabilities from React Native can be done using Cordova plugins without having to rewrite all those plugins.

How?

Navigate to the root of your ReactNative project and install npm install react-native-cordova-plugin --save. Then follow the steps below

Step 1 - Setup

First, the Android or the iOS project needs to be set up so that it depends on this react-native-cordova-plugin adapter.

Android

First, open the file projectRoot\settings.gradle and replace include ':app' with the following

include ':cordovaplugin', ':app'
project(':cordovaplugin').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-cordova-plugin/framework/android')

Then, add the adapter as a dependency. Open the file projectRoot/android/app/build.gradle and look for dependencies section. Add a new line in the dependencies saying compile project(':cordovaplugin')

Open the main react package, usually called MainActivity.java in the projectRoot/android/app/src/main/java/com/appName/ folder.

Make the class extend io.cordova.reactnative.CordovaActivity instead of Activity. For example, replace the line that says public class MainActivity extends Activity implements DefaultHardwareBa... with public class MainActivity extends io.cordova.reactnative.CordovaActivity implements DefaultHardware...
Add .addPackage(super.cordovaPluginPackage) just below the line .addPackage(new MainReactPackage())

If you want to continue extending Activity and not change it to CordovaActivity, just look at the io.cordova.reactnative.CordovaActivity.java and add the methods and field memebers as in the file.

iOS

Not yet implemented for iOS yet.

Part 2 - Adding Plugins

The next step would be to add Cordova Plugins in the project. Now that react-native-cordova-plugin package is added to node_modules you can add packages using

$ node node_modules\.bin\cordova-plugin add cordova-plugin-device

The plugins are downloaded from the npm registry and installed in the project's node_modules folder. The files in each plugin are also converted to a form that can be consumed by the ReactNative project.

Part 3 - Using the Plugins

To use a plugin, simply require var cordova = require('react-native-cordova-plugin');. You can then start using the Cordova plugin APIs using cordova.device.getInfo(console.log.bin(console.log), console.log.bind(console));.

This example file shows a sample application.

Contribute

Would love to have an contributions to this project, especially to get the iOS part working. Please send in a pull request (explaining what it does) and I can merge it in !!
