const Hapi = require('hapi');
const Understood = require('understood');
 
 
server.register({ register: Understood, options: { localesDir: (__dirname + '/locales'), default: 'fr-CA' } }, (err) => {
  // handle err
 
  server.route({
    method: 'GET',
    path: '/',
    handler: function (request, reply) {
      reply(request.locale);
    }
