getSupportedLanguages()

The getSupportedLanguages function returns the array of supported languages configured in your i18n-keyless application. This function is useful for building dynamic language selectors or checking if a specific language is supported.

Function Signature​

getSupportedLanguages(): Lang[]

Return Value​

Lang[]​

type: Lang[]

Returns an array of supported language codes as configured during initialization. The Lang type includes all possible languages: "fr" | "en" | "nl" | "it" | "de" | "es" | "pl" | "pt" | "ro" | "hu" | "sv" | "tr" | "ja" | "cn" | "ru" | "ko" | "ar" | "cz".

getSupportedLanguages vs AVAILABLE_LANGS​

getSupportedLanguages() returns only the languages your project enabled in init({ languages: { supported: [...] } }). If you want the full list of every language i18n-keyless can translate to (regardless of your config), import the AVAILABLE_LANGS constant instead:

import { AVAILABLE_LANGS } from 'i18n-keyless-node';

// All 18 languages i18n-keyless supports, ready to spread into init({ supported })
console.log(AVAILABLE_LANGS);

Notes​

  • Returns the exact array configured in I18nKeyless.init({ languages: { supported: [...] } })
  • The array reflects the languages configured at initialization time
  • Useful for building dynamic interfaces that adapt to your language configuration
  • The order of languages in the array matches the order specified during initialization
  • For the full set of available language codes (not just the ones enabled in your project), use AVAILABLE_LANGS
