I18Next.Neti18next for .NET

The same translation files and features as i18next, with dependency injection, IStringLocalizer and ASP.NET Core integration.

i18next compatible

JSON v1 to v4 plurals, context, nesting, fallbacks, objects and arrays, getFixedT, keyPrefix and the built-in Intl formats.

number, currency, datetime, relativetime and list formats produce the output of the browser Intl APIs, based on bundled CLDR data.

JSON, YAML, XML, INI, gettext, HTTP, in-memory and delegate backends, chained with caching and expiry.

A source generator creates key constants and typed translation methods from your JSON files and checks them for missing keys.

Translations are resolved synchronously from cached namespaces with few allocations, many times faster than i18next on Node.

Runs on .NET Framework 4.6.2 and later, .NET 6, .NET 8, .NET 10 and .NET 11.
