# ex-react-native-i18n for Expo

Integrates [I18n.js](https://github.com/fnando/i18n-js) with React Native and ***Expo***. Uses the device's locale as default.







## Automatic setup

`$ npm install ex-react-native-i18n --save`

or

`$ yarn add ex-react-native-i18n`

## Usage

Before copy usage see this issue: https://github.com/xcarpentier/ex-react-native-i18n/issues/7

```javascript

import I18n from 'react-native-i18n'

class Demo extends React.Component {

  // Async call to init the locale

  componentWillMount() {

    I18n.initAsync();

  }

  render () {

    return (

      {I18n.t('greeting')}

    )

  }

}

// Enable fallbacks if you want `en-US` and `en-GB` to fallback to `en`

I18n.fallbacks = true

I18n.translations = {

  en: {

    greeting: 'Hi!'

  },

  fr: {

    greeting: 'Bonjour!'

  }

}

```

This will render `Hi!` for devices with the English locale, and `Bonjour!` for devices with the French locale.

### Fallbacks

When fallbacks are enabled (which is generally recommended), `i18n.js` will try to look up translations in the following order (for a device with `en_US` locale):

- en-US

- en

**Note**: iOS locales use underscored (`en_US`) but `i18n.js` locales are dasherized (`en-US`). This conversion is done automatically for you.

```js

I18n.fallbacks = true

I18n.translations = {

  'en': {

    greeting: 'Hi!'

  },

  'en-GB': {

    greeting: 'Hi from the UK!'

  }

}

```

For a device with a `en_GB` locale this will return `Hi from the UK!'`, for a device with a `en_US` locale it will return `Hi!`.

### Device's locale

You can get the device's locale with the `RNI18n` native module:

```js

import I18n from 'ex-react-native-i18n'

const deviceLocale = I18n.locale

```

Returns `en-US`.

### I18n.js documentation

For more info about I18n.js methods (`localize`, `pluralize`, etc) and settings see [its documentation](https://github.com/fnando/i18n-js#setting-up).
