Multi-language support in React uses i18n frameworks like i18next or react-intl to manage translations. Set up i18n with JSON translation files for each language, configure locale detection, and bind language switching to your app state. This enables dynamic language switching and locale-aware content rendering across your application.

RTL support requires configuring your i18n framework to detect right-to-left languages, then applying directional CSS and HTML attributes based on the active locale. i18next and similar frameworks automate locale detection and can trigger stylesheet swaps or CSS variables to flip layout, text alignment, and component positioning for Arabic, Hebrew, and other RTL languages.

Yes. i18n frameworks support automated text extraction to identify untranslated strings, missing translation detection, and integration with translation management services. You can embed these checks in CI/CD to flag incomplete translations before deployment and automate syncing translations from external services into your codebase.

i18n frameworks provide locale-aware formatting functions that apply regional conventions for dates, numbers, and currency without manual string manipulation. Configure your locale data, then use built-in formatters to automatically display 1,234.56 as 1.234,56 in German or apply locale-specific currency symbols and decimal separators.

Yes. i18next handles nested JSON keys for organized translation structures, ICU pluralization rules for singular/plural forms based on count, and interpolation to inject dynamic values into translated strings. These features reduce key duplication and enable complex translation logic without framework-specific workarounds.

Namespace translations into separate files, lazy-load language packs on demand, and cache loaded translations to avoid repeated parsing. Code splitting ensures only the active locale's translations load initially, reducing bundle size. Combine with HTTP caching and CDN delivery for production deployments serving multiple languages.
