Rendering Multi-language Info

This page shows you how to retrieve the language code and alternate language versions of a document.

Before Reading

This page assumes that you have retrieved your content and stored it in a variable named document

Get the document language code

Here is how to retrieve the language code of a document queried from your repository. This might give "en-us" (American english), for example.

const language = document.lang;

Get the alternate language versions

Next we will access the information about a document's alternate language versions. You can loop through the alternate_languages array and access the id, uid, type, and language code of each as shown below.

  var id =;
  var uid = altLang.uid;
  var type = altLang.type;
  var lang = altLang.lang;
