我正在使用i18n-js库。
为了设置其配置,我正在执行以下操作:
export function setI18nConfig(locale = undefined) {
// Fallback if no available language fits
const fallback = DEFAULT_APP_LANGUAGE;
const language =
APP_LANGUAGES.find((language) => language.locale === locale) ?? fallback;
const { locale: _locale, isRTL } = language;
// Clear the translation cache
translate.cache.clear();
// Update the layout direction
I18nManager.forceRTL(isRTL);
// Set the i18n-js config
i18n.locale = _locale;
i18n.translations = { [_locale]: translationGetters[_locale]() };
// Set moment config
moment.locale(_locale);
// Return the appropiate locale
return _locale;
}
如您所见,为了设置翻译字典,我将其称为 getter:
export const translationGetters = {
en: () => require("../../../assets/languages/en/translations.json"),
es: () => require("../../../assets/languages/es/translations.json"),
fr: () => require("../../../assets/languages/fr/translations.json"),
it: () => require("../../../assets/languages/it/translations.json"),
pt: () => require("../../../assets/languages/pt/translations.json"),
};
为了建立备用语言,我只是想在我的应用程序语言数组中找到给定的语言环境(函数参数)。
export const APP_LANGUAGES = [
{
name: "English",
locale: "en",
isRTL: false,
},
{
name: "French",
locale: "fr",
isRTL: false,
},
{
name: "Italian",
locale: "it",
isRTL: false,
},
{
name: "Portuguese",
locale: "pt",
isRTL: false,
},
{
name: "Spanish",
locale: "es",
isRTL: false,
},
];
如果它不在列表中,那么我使用 DAFAULT_APP_LANGUAGE 作为翻译。
export const DEFAULT_APP_LANGUAGE = APP_LANGUAGES[0];
这是设置 i18n.js 后备的典型或正确方法吗?
没有任何简单的方法可以做到这一点吗?
我的意思是,类似:
i18n.fallbackLanguage = "en";
i18n.locale = locale;
i18n.translations = {
[locale]: translationGetters[locale](),
[fallbackLanguage]: translationGetters[fallbackLanguage]()
};
注意:我还需要为后备设置 isRTL 配置!
