Multi-Language info

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

Before Reading

This page assumes that you have already retrieved a document from your Prismic repository and stored it in a variable named document.

Get the document language code

You can get the language code of a document by accessing its lang property. This might give "en-us" (American English) or "fr-fr" (French) for example:

const languageCode = document.lang;

Get the alternate language versions

Next we will see how to access the information about a document's alternate language versions. You can get the alternate languages using the alternate_languages property. Then simply loop through the array and access the ID, UID, type and language code of each as shown below:

document.alternate_languages.forEach(function (altLang) {
  const id =;
  const uid = altLang.uid;
  const type = altLang.type;
  const languageCode = altLang.lang;

Get a specific alternate language version

Here's an example of how to get a specific alternate language version of a document. In this example we want the French version:

const getAlternateLanguage = function (document, languageCode) {
  for (const altLang of document.alternate_languages) {
    if (altLang.lang === languageCode) {
      return altLang;
  return null;

const frenchAltLang = getAlternateLanguage(document, 'fr-fr');
const frenchDocId =;
const frenchDocUid = frenchAltLang.uid;
const frenchDocType = frenchAltLang.type;
