Nunjucks extension for translation. With this
you can use the trans and endtrans tags or the trans filter.
$ npm install nunjucks-translation
Example using static translations
import { TranslationExtension } from 'nunjucks-translation';
const translationExtension = new TranslationExtension({
translations: {
de: {
message: {
hello1: 'Hallo',
hello2: 'Hallo {name}',
},
},
en: {
message: {
hello1: 'Hello',
hello2: 'Hello {name}',
}
},
},
locale: 'de',
fallbackLocale: 'en',
});
nunjucksEnv.addExtension('translation-extension', translationExtension);
nunjucksEnv.addFilter('trans', (textId: string, locale: string, params: object) =>
translationExtension.translateText(textId, locale, params),
);Example using translations from JSON file:
import * as fs from 'fs';
import { TranslationExtension } from 'nunjucks-translation';
const translationExtension = new TranslationExtension(
JSON.parse(
fs.readFileSync('/path/to/translation.json', 'utf8'),
)
);
nunjucksEnv.addExtension('translation-extension', translationExtension);
nunjucksEnv.addFilter('trans', (textId: string, locale: string, params: object) =>
translationExtension.translateText(textId, locale, params),
);You can use the trans and endtrans tags to translate your content.
