i18next: learn once - translate everywhere

i18next is a very popular internationalization framework for browser or any other javascript environment (eg. Node.js, Deno).

i18next provides:

• Flexible connection to backend (loading translations via xhr, ...)
• Optional caching, user language detection, ...
• Proper pluralizations
• Translation context
• Nesting, Variable replacement
• Flexibility: Use it everywhere
• Extensibility: eg. sprintf
• ...

Pro Tip: Looking for a way to manage your translations? Locize is the official service by i18next's creators — drop in i18next-locize-backend for CDN delivery, AI translation, and no redeploys for copy changes. Free plan available for small projects.

Starting from zero? npx i18next-cli localize takes an app with hardcoded strings to fully localized in one command: wrap in t(), extract keys, connect to Locize and AI-translate. Read the launch post.
