ex-react-native-i18n for Expo

$ 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
import I18n from 'react-native-i18n'
class Demo extends React.Component {
// Async call to init the locale
componentWillMount() {
I18n.initAsync();
}
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.
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:
import I18n from 'ex-react-native-i18n'
const deviceLocale = I18n.locale
Returns en-US
.
