hapi-locale-17

Locale and language detection for Hapi Server.

Evaluates locale information from accept-language header and query or path parameter. Decorates Hapi request object with request.getLocale() available in all route handlers.

Priority of evaluation: (1) locale query parameter (if provided), (2) locale path parameter (if provided), (3) accept-language http request header, (4) fallback locale (the first locale in locales list).

Decorated method request.getLocale() can be renamed. Query and path parameters locale can be renamed or switched off.
