#### iOS

1. In XCode, in the project navigator, right click Libraries ➜ Add Files to [your project's name]
2. Go to node_modules ➜ rn-user-defaults and add RNUserDefaults.xcodeproj
3. In XCode, in the project navigator, select your project. Add libRNUserDefaults.a to your project's Build Phases ➜ Link Binary With Libraries
4. Run your project (Cmd+R)<

#### Android

- Edit android/settings.gradle and add the following

``
include ':app', ':rn-user-defaults'

project(':rn-user-defaults').projectDir = new File(rootProject.projectDir, '../node_modules/rn-user-defaults/android')
`

- Edit android/app/build.gradle and add the following line before the react section in dependencies

`
dependencies {
...
implementation project(':rn-user-defaults')
implementation "com.facebook.react:react-native:+"
}
`

- Add these lines to MainApplication.java

`
...
import chat.rocket.userdefaults;
...
@Override
protected List getPackages() {
@SuppressWarnings("UnnecessaryLocalVariable")
List packages = new PackageList(this).getPackages();
...
packages.add(new RNUserDefaultsPackage());
return packages;
}
`

Usage


`javascript
import RNUserDefaults from 'rn-user-defaults';

RNUserDefaults.set('key', 'value').then(function() {console.log('done')}); // done
RNUserDefaults.get('key').then(function(value) {console.log(value)}); // value
RNUserDefaults.setObjectForKey('objKey', { dog: 1 }).then(function() {console.log('done')}); // done
RNUserDefaults.objectForKey('objKey').then(function(value) {console.log(value)}); // { dog: 1 }
`

Static methods

Now you can use static methods to access current SharedPreferences or UserDefaults classes on native modules.

#### Android
`java
import android.content.SharedPreferences;
import chat.rocket.userdefaults.RNUserDefaultsModule;

SharedPreferences sharedPreferences = RNUserDefaultsModule.getPreferences();
String exampleString = sharedPreferences.getString("STRING_KEY", "");

SharedPreferences sharedPreferences1 = RNUserDefaultsModule.getPreferences(reactApplicationContext);
String exampleString1 = sharedPreferences1.getString("STRING_KEY", "");

SharedPreferences sharedPreferences2 = RNUserDefaultsModule.getPreferences(reactApplicationContext, contextName, preferencesName);
String exampleString2 = sharedPreferences2.getString("STRING_KEY", "");
`

#### iOS
`objective-c
#import "RNUserDefaults.h"

NSDictionary *exampleObject = [[RNUserDefaults getDefaultUser] objectForKey:@"OBJECT_KEY"];
`
