        translations: { // These are the displayed translation strings for each language
          // The property names define the language code of the translations
          en: {
            ERROR_NON_OPTIONAL: "<custom message here>", // for frontend validation error
            "Field is not optional": "<custom message here>" // for mapping message returned from the backend
    appInfo: {
        appName: "...",
        apiDomain: "...",
        websiteDomain: "...",
    recipeList: [
      // ...
