I18n

A minimal localisation layer — locale detection, Intl-backed number and date formatting, and a dictionary-lookup t. Formatting delegates to Intl, so the locale data is the platform's rather than the bundle's, while translation is deliberately naive: a flat dictionary lookup. For ICU messages, per-language plural categories or namespaced catalogs, use i18next or FormatJS. English-only pluralisation lives in strings.

Example

import { formatNumber, t } from '@rtorcato/js-common/i18n'

const dict = {
  en: { greeting: 'Hello' },
  fr: { greeting: 'Bonjour' },
}

t('greeting', dict, 'fr') // 'Bonjour'
t('greeting', dict, 'de') // 'Hello'  — falls back to English
t('missing', dict, 'fr')  // 'missing' — then to the key itself

formatNumber(1234.5, 'de-DE') // '1.234,5'

Import

import { detectLanguage, formatDateI18n, formatNumber } from '@rtorcato/js-common/i18n'
