React Native i18next (Complete Guide): RTL, Interpolation & Detect
Ready to make your React Native app go global? 🌍 In this tutorial, we build a complete multi-language system using i18next.
Many tutorials only show you how to translate static text. In this video, we go deeper. I’ll show you how to handle complex scenarios like dynamic variables (interpolation), pluralization (handling singular vs. plural forms), and even how to completely flip your app's layout for RTL languages like Arabic.
We will also implement a professional user experience by detecting the device's default language on the first launch and persisting the user's language preference so it stays saved even after they restart the app.
🚀 What we cover in this video:
Setup: Installing and configuring i18next & react-i18next.
Interpolation: passing dynamic data into your translations.
Pluralization: Handling "1 item" vs "5 items" logic automatically.
RTL Support: forcing LayoutDirection for Arabic/Hebrew support.
Auto-Detection: Using expo-localization to find the user's phone language.
Persisting State: Saving the chosen language using AsyncStorage.
