Installing new languages


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:

(using your preferred language's code instead of 'en').

Which other languages are supported out of the box?

By default we provide French and English, but you can add many more languages:

  • Catalan
  • Chinese (Simplified)
  • Chinese (Traditional)
  • Danish
  • German
  • Italian
  • Japanese
  • Hungarian
  • Korean
  • Polish
  • Portuguese
  • Portuguese (Brazilian)
  • Russian
  • Romanian
  • 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 file to this where the server-side translations are stored
  5. Translate all keys in the 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/scripts/components/language/language.service.js
  3. Remove the src/main/resources/i18n/ file
