react-native-panda-i18n v1.0.0

react-native-panda-i18n

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

History

The package github.com/AlexanderZaytsev/react-native-i18n.git which had been deprecated. 并且，这个库在Android上的支持已经过时了，所以我简单修改了Android平台的 build.gradle 文件。 另外，我也并没有需要和打算升级到最新的本地化解决方案。所以，我开始自己维护这个库，只是库的名字难看了些。 可能未来几周我有时间了也可以把这个库升级到最新的本地化解决方案吧。鬼知道我什么时候有激情和闲心干这件事。

Installation

Using yarn (recommended)

$ yarn add react-native-panda-i18n

Using npm

$ npm install react-native-panda-i18n --save

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.

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-panda-i18n'

and run

pod install

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.

You also need to add the localizations you intend to support to your iOS project. To do that open your Xcode project:

$ open <your-project>.xcodeproj

And add the localizations you will support as shown here:

Android

Add react-native-panda-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-panda-i18n/android')

Include it as dependency in ./android/app/build.gradle file:

dependencies {
    // ...
    compile project(':react-native-panda-i18n')
}

Finally, you need to add the package to your MainApplication (./android/app/src/main/java/your/bundle/MainApplication.java):

import com.panda8z.RNI18n.RNI18nPackage; // <-- Add to ReactNativeI18n to the imports

// ...

@Override
protected List<ReactPackage> getPackages() {
    return Arrays.<ReactPackage>asList(
        new MainReactPackage(),
        // ...
        new RNI18nPackage(), // <-- Add it to the packages list
    );
}

// ...

After that, you will need to recompile your project with react-native run-android.

⚠️ Important: You'll need to install Android build tools 27.0.3

Usage

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

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