express-rest-i18n

Dead simple i18n middleware for Express REST APIs. Version 1.0.1 provides lightweight, dependency-free internationalization with nested message support and automatic locale detection via query, header, or cookie. No build tools, no extra dependencies; simply define messages in JSON and use the `t()` method on `req` or `res`. Unlike heavier i18n libraries, it focuses solely on REST APIs with a minimal footprint. Released as stable, with no active development but no known issues.
