Introduction Permalink to "Introduction"

During the generation of a new project you will be asked whether or not you want to enable internationalization support.

If enabling it you will need to select the native language of your application. After that you can choose the additional languages you would like to install. If you don’t want to support any additional languages from start you can always add languages later when needed by running the language sub-generator.

If you are sure you will never translate this application into another language you should not enable the internationalization.

How to add a new language that is not supported? Permalink to "How to add a new language that is not supported?"

All languages are saved in the folder src/main/webapp/i18n (client side) and src/main/resources/i18n (server side)

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 is where all the front-end translations are stored)
  2. Translate all files under the folder src/main/webapp/i18/new_lang
  3. Add the language code new_lang to the languages variable defined in src/main/webapp/app/shared/language/find-language-from-key-pipe.ts

    private languages: { [key: string]: { name: string; rtl?: boolean } } = {
        en: { name: 'English' },
        new_lang: { name: 'New Language' }
        // jhipster-needle-i18n-language-key-pipe - JHipster will add/remove languages in this object
  4. In the src/main/resources/i18n folder, copy the file to (this is where the server-side translations are stored)
  5. Translate all keys in the file
  6. Add the new language bundling to webpack/webpack.common.js

    new MergeJsonWebpackPlugin({
        output: {
            groupBy: [
                { pattern: "./src/main/webapp/i18n/en/*.json", fileName: "./i18n/en.json" },
                { pattern: "./src/main/webapp/i18n/new_lang/*.json", fileName: "./i18n/new_lang.json" }
                // jhipster-needle-i18n-language-webpack - JHipster will add/remove languages in this array

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