Description

import { createNavigation } from 'next-intl/navigation';
import { defineRouting } from 'next-intl/routing';
import { LanguageCode } from '@/generated-types';

export const routing = defineRouting({
  // A list of all locales that are supported
  locales: [LanguageCode.en, LanguageCode.de],
  // Used when no locale matches
  defaultLocale: LanguageCode.en,
  localePrefix: 'as-needed',
  localeDetection: false,
  domains: [
    {
      domain: 'www.issilo.com',
      defaultLocale: LanguageCode.en,
      locales: [LanguageCode.en],
    },
    {
      domain: 'www.issilo.de',
      defaultLocale: LanguageCode.de,
    },
  ],
});

the domain based localed always return en

if we use prefix locale (/en,/de) it works www.issilo.com ==> en www.issilo.de ===> en (wrong)

BTW: we have multiple domain points one next server port: 3000,

[tianyingchun]

  [ 'x-forwarded-for', '127.0.0.1' ],
  [ 'x-forwarded-host', 'www.issilo.de:443' ],
  [ 'x-forwarded-port', '4001' ],
  [ 'x-forwarded-proto', 'http' ],
  [ 'x-forwarded-server', 'www.issilo.de' ],
  [ 'x-nginx-proxy', 'true' ],
  [ 'x-real-ip', '127.0.0.1' ]

nginx proxy forward, it caused for port 443? i used https

i found i need to config domains with. below it works

export const routing = defineRouting({
  // A list of all locales that are supported
  locales: [LanguageCode.en, LanguageCode.de],
  // Used when no locale matches
  defaultLocale: LanguageCode.en,
  localePrefix: 'never',
  localeDetection: true,
  domains: [
    {
      domain: 'www.issilo.com:443',
      defaultLocale: LanguageCode.en,
      locales: [LanguageCode.en],
    },
    {
      domain: 'www.issilo.de:443',
      defaultLocale: LanguageCode.de,
      // If there are no `locales` specified on a domain,
      // all available locales will be supported here
    },
  ],
});
