Frameworks

Better i18n ships first-class React SDKs for every major framework, plus native SDKs for mobile — all CDN-first, so translations load from the edge with no build step and update without a redeploy.

React & web frameworks #

• Next.js — App Router + Pages Router, middleware locale routing, RSC-friendly
• TanStack Start — full SSR with type-safe routing
• Vite — client-side React apps and React Router
• Remix & Hydrogen — loader-based SSR and Shopify Hydrogen storefronts

Native & mobile #

• Expo — React Native with offline caching and instant language switching
• iOS (Swift) — reactive translations in SwiftUI
• Flutter — native Dart SDK with offline support

Server #

• Server SDK — runtime-agnostic server-side i18n for any JavaScript backend (Node, Hono, tRPC, Supabase, Better Auth)

Shared concepts #

Every framework SDK builds on the same primitives:

• Quick Start — five-minute setup
• Provider — configure BetterI18nProvider
• Translations — the t() function and namespaces
• Locale — locale detection and switching
• Geo Detection — infer locale from region
• Formatting — numbers, dates, and plurals
• Server Utilities — server-side fetching
