Updates in v2.5.4

Funktionen

• Split Survey JSON Schema to Load Translations Dynamically
  • Introduced support for splitting a survey JSON schema into a layout schema and separate localization schemas, enabling dynamic loading of translations and reducing overall schema size.
  • By default, a survey JSON schema includes all user-defined translations for every language configured in the survey. When a survey supports many languages, this can significantly increase the size of the JSON schema.
  • To optimize payload size and improve loading performance, you can now split the survey schema into a layout schema that contains no textual content and one or more localization schemas that store translations for specific languages. You can then load only the required languages at runtime.
  • To support this workflow, the SurveyModel API has been extended with the following members:
    • getLocalizationJSON(locales) method
      • Generates a localization JSON schema that containing all languages or a specified subset of locales.
    • mergeLocalizationJSON(json, locales) method
      • Applies a localization schema to an existing survey model. You can optionally specify which languages to apply.
    • storeLocaleStrings option in the toJSON(options) method
      • When storeLocaleStrings is disabled, toJSON() generates a layout-only JSON schema without any textual content.
