# react-native-i18n
Integrates [I18n.js](https://github.com/fnando/i18n-js) with React Native. Uses the device's locale as default.
<br/>
<br/>
## Installation
If you're on react-native >= 0.40: `$ npm install react-native-i18n --save`
If you're on react-native < 0.40: `$ npm install react-native-i18n@0.1.1 --save`
**Using npm**
`$ npm install react-native-i18n --save`
**Using yarn**
`$ yarn add react-native-i18n`
## Automatic setup
After installing the npm package you need to link the native modules.
If you're using React-Native < 0.29 install [rnpm](https://github.com/rnpm/rnpm) with the command `npm install -g rnpm` and then link the library with the command `rnpm link`.

If you're using React-Native >= 0.29 just link the library with the command `react-native link`.
You can do so using [rnpm](https://github.com/rnpm/rnpm).
If you're having any issue you can also try to install the library manually as follows.
**[WARNING]** There is currently [an issue](https://github.com/AlexanderZaytsev/react-native-i18n/issues/43) with the react-native link / rnpm install method. Prefers the manual install until it is solved.
## Manual setup
### iOS
Add `RNI18n.xcodeproj` to **Libraries** and add `libRNI18n.a` to **Link Binary With Libraries** under **Build Phases**.
[More info and screenshots about how to do this is available in the React Native documentation](http://facebook.github.io/react-native/docs/linking-libraries-ios.html#content).
You also need to add the **localizations** you intend to support to the iOS project. To do that open
your Xcode project:

### Android
Add `react-native-i18n` to your `./android/settings.gradle` file as follows:
```
include ':app', ':react-native-i18n'
project(':react-native-i18n').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-i18n/android')
```
Include it as dependency in `./android/app/build.gradle` file:
```
dependencies {

Finally, you need to add the package to your MainApplication (`./android/app/src/main/java/your/bundle/MainApplication.java`):
```java
import com.i18n.reactnativei18n.ReactNativeI18n; // <-- Add to ReactNativeI18n to the imports

new RNI18nPackage(), // <-- Add it to the packages list
...
);
}

After that, you will need to recompile your project with `react-native run-android`.
**Note: You'll need Android build tools 25.0.2**
## Usage
```javascript
import I18n from 'react-native-i18n'
