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?

To start using Cordova Plugins in your ReactNative project, follow these steps

  1. Getting Started
  2. Setup your ReactNative project with this
    react-native-cordova-plugin
    module.
  3. Add/Removing the required Cordova Plugin to the ReactNative project. (link)
  4. Use the required Cordova Plugin in your ReactNative Javascript code. (link)

You can also check out the example project in the

example
branch of this repository.

Step 0 - Getting Started

First, Install this native module in your ReactNative project by running the following at the root of your ReactNative Project.

npm install react-native-cordova-plugin --save

Step 1 - Setup the ReactNative project

As with all other React Native plugins, the integration experience is different for iOS and Android, so perform the next set of setup steps depending on which platform(s) you are targetting.

Step 1.1 For Anrdoid

  1. In android/settings.gradle file, make the following changes
  include ':app'
+ include ':cordovaplugin'
+ project(':cordovaplugin').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-cordova-plugin/framework/android')
  1. In android/app/build.gradle, look for
    dependencies
    section and add the following line
...
android {
  ...
}
dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile "com.android.support:appcompat-v7:23.0.1"
    compile "com.facebook.react:react-native:+"  // From node_modules    ...
+   compile project(':cordovaplugin')
}

  1. In android/app/src/main/java/com/appname/MainActivity.java (your main Android activity file), add a reference to react-native-cordova-plugin. ```diff ... + import io.cordova.reactnative.CordovaPluginPackage; ... public class MainActivity extends ReactActivity { ... @Override protected List getPackages() { return Arrays.asList( new MainReactPackage(), + cordovaPluginPackage = new CordovaPluginPackage(this) ); } + private CordovaPluginPackage cordovaPluginPackage; + @Override + protected void onCreate(Bundle savedInstanceState) { + super.onCreate(savedInstanceState); + cordovaPluginPackage.setSavedInstanceState(savedInstanceState); + } + @Override + public void onActivityResult(int requestCode, int resultCode, Intent intent) { + super.onActivityResult(requestCode, resultCode, intent); + cordovaPluginPackage.onActivityResult(requestCode, resultCode, intent); + } }
### Step 3 - Adding Cordova Plugin to ReactNative project
To install a plugin, say the `cordova-plugin-camera` and `cordova-plugin-contacts`, run the following command from the root of your ReactNative project

```bash $ node_modules/.bin/cordova-plugin add cordova-plugin-camera cordova-plugin-contacts

You can install plugins that require variables as well. Here we add the Cordova purchase plugin that handles In App Purchasing, supplying it the Billing Key of our Android application. You would replace the fake billing key (MIIBFJIEOF....) with your billing key (a very long string).

$ node_modules/.bin/cordova-plugin add cc.fovea.cordova.purchase --variable BILLING_KEY="MIIBFJIEOF...."

The add command takes one of more Cordova plugins that can be added to the project. To remove a plugin, use

bash
$ node_modules/.bin/cordova-plugin rm cordova-plugin-contacts

Step 4 - Using the Plugins

In either index.android.js or any other component, simply require this module using

var Cordova = require('react-native-cordova-plugin');

In Cordova, all plugin methods are available on the

window
object. ReactNative does not run in a WebView and does not have a
window
object. Thus, all the methods and constants that a Cordova plugin defines are available in the
Cordova
object that was just required using the statement above.
Cordova.navigator.camera.getPicture(onSuccess, onFail, {sourceType: Cordova.Camera.PictureSourceType.SAVEDPHOTOALBUM)});

// Listen to cordova-plugin-network-information plugin's events Cordova.addEventListener('offline', onEvent);

There are more examples of using the plugins in the examples branch - look for files with plugin names.

Older Versions

To run this plugin for older versions of ReactNative, use older versions published on npm

To use CLI commands with react-native-cordova-plugin versions less than 1.0.0, replace

$ node_modules/.bin/cordova-plugin
with
$ node_modules/.bin/react-native-cordova-plugin
.

Troubleshooting

Some JavaScript errors may be caused due to the way

cordova.js
is generated. You can try tto re-generate
cordova.js
using
$ node_modules/.bin/cordova-plugin repair

If that does not work, try cleaning all the cordova plugins using the following, and then add the plugins again

bash
$ node_modules/.bin/cordova-plugin clean

If none of these work, please open an issue with a prefix [QUESTION] in the title, and I could try helping you. It would help to open the issue with a reduced way to reproduce the error.
