API Reference

Runtime API

• Methods — $t, $ts, $_t, $_ts, locale switching, routing helpers
• Events — i18n:register, i18n:beforeLocaleSwitch, i18n:afterLocaleSwitch
• Translations and Cache — TranslationStorage, payload loading, $clearCache

Server middleware

Server handlers use dedicated middleware (not the client $t helpers):

• useTranslationServerMiddleware — translate in API routes and server handlers
• useLocaleServerMiddleware — read detected locale and metadata

See the full Server-Side Translations guide for setup, locale detection priority, and examples.
