The idea behind the example

This example app shows how to integrate react-i18next with Next.

Plus:

• Routing and separating translations into multiple files (lazy load them on client routing)
• Child components (pure or using translation hoc)

Features of this example app

• Server-side language negotiation
• Full control and usage of i18next on express server using i18next-express-middleware which asserts no async request collisions resulting in wrong language renderings
• Support for save missing features to get untranslated keys automatically created locales/{lng}/{namespace}.missing.json -> never miss to translate a key
• Proper pass down on translations via initialProps
• Taking advantage of multiple translation files including lazy loading on client (no need to load all translations upfront)
• Use express to also serve translations for clientside
• In contrast to react-intl the translations are visible both during development and in production
