React Native + i18n.js

react-native-i18n

Integrates I18n.js with React Native. Uses the device's locale as default.

Installation

$ npm install react-native-i18n --save

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.

Usage

var I18n = require('react-native-i18n');

var Demo = React.createClass({
  render: function() {
    return (
      <Text>{I18n.t('greeting')}</Text>
    )
  }
});

// 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.

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:

var deviceLocale = require('react-native').NativeModules.RNI18n.locale

Returns en_US.
