  keySeparator: '.',
  // Key separator used in your translation keys
  // If you want to use plain english keys, separators such as `.` and `:` will conflict. You might want to set `keySeparator: false` and `namespaceSeparator: false`. That way, `t('Status: Loading...')` will not think that there are a namespace and three separator dots for instance.

  locales: SUPPORTED_LANGUAGES.map((l) => l.code),
  // An array of the locales in your applications

  namespaceSeparator: ':',
  // Namespace separator used in your translation keys
  // If you want to use plain english keys, separators such as `.` and `:` will conflict. You might want to set `keySeparator: false` and `namespaceSeparator: false`. That way, `t('Status: Loading...')` will not think that there are a namespace and three separator dots for instance.

  output: 'public/locales/$LOCALE/$NAMESPACE.json',
  // Supports $LOCALE and $NAMESPACE injection
  // Supports JSON (.json) and YAML (.yml) file formats
  // Where to write the locale files relative to process.cwd()

  pluralSeparator: '_',

  customValueTemplate: null,
  // If you wish to customize the value output the value as an object, you can set your own format.
  // ${defaultValue} is the default value you set in your translation function.
  // Any other custom property will be automatically extracted.

  // Example:
  // {
  //   message: "${defaultValue}",
  //   description: "${maxLength}", // t('my-key', {maxLength: 150})
  // }

  resetDefaultValueLocale: null,
  // The locale to compare with default values to determine whether a default value has been changed.
  // If this is set and a default value differs from a translation in the specified locale, all entries
  // for that key across locales are reset to the default value, and existing translations are moved to
  // the `_old` file.

  i18nextOptions: null,
  // If you wish to customize options in internally used i18next instance, you can define an object with any
  // configuration property supported by i18next (https://www.i18next.com/overview/configuration-options).
  // { compatibilityJSON: 'v3' } can be used to generate v3 compatible plurals.
