This is an update of react-native-i18n

react-native-i18n-new

Integrates I18n.js with React Native. Uses the user preferred locale as default.

Installation

Using npm

$ npm install react-native-i18n-new

Automatic setup

After installing the npm package you need to link the native modules.

If you're using React-Native >= 0.29 just link the library with the command react-native link react-native-i18n-new.

If you're using React-Native < 0.29, install rnpm with the command npm install -g rnpm and then link the library with the command rnpm link.

If you're having any issue you can also try to install the library manually as follows.

Automatic setup with Cocoapods

After installing the npm package, add the following line to your Podfile

pod 'RNI18n', :path => '../node_modules/react-native-i18n-new'

and run

pod install

Usage

import I18n from "react-native-i18n-new";
// OR const I18n = require('react-native-i18n-new').default

class Demo extends React.Component {
  render() {
    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.

Usage with multiple location files

// app/i18n/locales/en.js

export default {
  greeting: 'Hi!'
};

// app/i18n/locales/fr.js

export default {
  greeting: 'Bonjour!'
};

// app/i18n/i18n.js

import I18n from 'react-native-i18n-new';
import en from './locales/en';
import fr from './locales/fr';

I18n.fallbacks = true;

I18n.translations = {
  en,
  fr
};

export default I18n;

// usage in component

import I18n from 'app/i18n/i18n';

class Demo extends React.Component {
  render () {
    return (
      <Text>{I18n.t('greeting')}</Text>
    )
  }
}

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 8 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 locales

You can get the user preferred locales with the getLanguages method:

import { getLanguages } from "react-native-i18n-new";

getLanguages().then((languages) => {
  console.log(languages); // ['en-US', 'en']
});
