How do you provide build configuration for multiple locales?

You can provide build configuration such as translation file path, name, format and application url in configuration settings of Angular.json file. For example, the German version of your application configured the build as follows,

"configurations": {
  "de": {
    "aot": true,
    "outputPath": "dist/my-project-de/",
    "baseHref": "/fr/",
    "i18nFile": "src/locale/messages.de.xlf",
    "i18nFormat": "xlf",
    "i18nLocale": "de",
    "i18nMissingTranslation": "error",
  }
