Installing new languages

Introduction

During the generation of a new project, JHipster only installs English and French languages. However, JHipster supports more languages that can be installed using this sub-generator.

The default language in JHipster is English, but this can be changed in the src/main/webapp/scripts/app/app.js, by modifying the following code:

$translateProvider.preferredLanguage('en');
(using your preferred language's code instead of 'en').

Which other languages are supported out of the box?

  • Catalan
  • Chinese (Simplified)
  • Chinese (Traditional)
  • Danish
  • German
  • Japanese
  • Hungarian
  • Korean
  • Polish
  • Portuguese (Brazilian)
  • Russian
  • Spanish
  • Swedish
  • Turkish

How to install new languages?

In order to install new languages, just type:

yo jhipster:languages

How to create a new language that is not supported?

All languages are saved in the folder /src/main/webapp/i18n

Here are the steps to install a new language called new_lang:

  1. Duplicate the /src/main/webapp/i18/en folder to /src/main/webapp/i18/new_lang: this where all the front-end translations are stored
  2. Translate all files under the folder /src/main/webapp/i18/new_lang

  3. Update the LANGUAGES constant defined in the folder src/main/webapp/components/language/language.service.js
    to add the new language new_lang

            
.constant('LANGUAGES', [
  'en', 'fr', 'new_lang'
  //JHipster will add new languages here
]
  4. In the src/main/resources/i18n folder, copy the messages_en.properties file to messages_new_lang.properties: this where the server-side translations are stored
  5. Translate all keys in the messages_new_lang.properties file

The new language new_lang is now available in the language menu, and is available both in the front-end AngularJS application and in the back-end Spring application.

How to remove an existing language?

Here are the steps to remove a language called old_lang:

  1. Remove the language folder from /src/main/webapp/i18/old_lang
  2. Remove the constant entry in src/main/webapp/components/language/language.service.js
  3. Remove the src/main/resources/i18n/messages_old_lang.properties file
