hapi-locale-17

Locale and language detection for Hapi Server v17.

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.

Install

npm install hapi-locale-17

Register the plugin with Hapi server like this:

const Hapi = require('hapi');
