i18n

This document describes how i18n work in hpapp.

Translations

We support multiple languages (but mainly Japanese and English) and assets/translations.json is a file that contains all language translations. The file represent key value pairs where the key is the English translation and the value is the translation in the target language.

{
  "English content here": {
    "ja": "日本語の翻訳をこちらに書く。"
  }
}

Then you can use the translation supported string as follows.

import { t } from "@hpapp/i18n";

function MyComponent() {
  return <Text>{t("English content here")}</Text>;
}

Note that our eslint rule (no-translation-entry) validates the translation key so that you can’t use a key that is not defined in the assets/translations.json or you can add // eslint-disable-next-line local-rules/no-translation-entry to the line to disable the validation.

Timezone

There is no special support for timezone including daylight saving. Date always use the system timezone so if you want to display a date in a specific timezone, you need to convert it manually.

Currency

There is no special support for currency. We expect everything is JPY.
