Display translated content
Transifex Native will automatically display content in the language currently selected in your application.
In order to allow changing the current language, you will need to implement a language picker in your code. You can use the Transifex Native JS API to build that and add the related logic.
Languages API
Fetches list of project languages from CDS, useful for creating a language picker.
tx.getLanguages(): Promise([
{
name: String,
code: String,
localized_name: String,
rtl: Boolean
},
...
])
Example
import { tx } from '@transifex/native';
tx.getLanguages()
.then(languages => {
console.log(languages);
// [{
// name: 'Greek',
// code: 'el',
// localized_name: 'Ελληνικά',
// rtl: false,
// }, {
// ...
// }]
})
.catch(console.log);
Get a list of available locales based on CDS.
tx.getLocales(): Promise(['code', 'code',...])
Language State API
Set current translation language
Fetches translations from the CDS and stores them in cache. When the promise returns, all content will be translated to that language.
tx.setCurrentLocale(localeCode): Promise
Example
tx.setCurrentLocale('el')
.then(() => console.log('content loaded'))
.catch(console.log);
Get current translation language
Returns the currently selected language code.
tx.getCurrentLocale(): String(localeCode)
Example
console.log(tx.getCurrentLocale());
Events API
You can use the events API to globally listen for various changes in the language state.
import { tx, onEvent, offEvent, sendEvent } from '@transifex/native';
import { LOCALE_CHANGED } from '@transifex/native';
// create an event handler
function handleLanguageChanged() {
// Current language was changed
console.log(tx.getCurrentLocale());
}
// register handler to a specific event
onEvent(LOCALE_CHANGED, handleLanguageChanged);
// remove handler from a specific event
offEvent(LOCALE_CHANGED, handleLanguageChanged);
// manually trigger a custom event with a payload
sendEvent("my_custom_event", { foo: "bar" });
