How to properly structure localized content in Cloud Firestore?

I'm thinking about migrating to Cloud Firestore from realtime ratabase and wondering how I can properly setup the datastructure for my localized content.

This is how it was structured in RTDB:

articles
   en-US
      article_01
   de-DE
      article_01

In Firestore, would I create something like this?

Collection: articles
   document: article_01

And then nest all the data of article_01 in two maps called 'en-US' and 'de-DE'?

Not sure if there's not a better way to structure localized data in Firestore?

Thanks for any help :)

There is a simple way for structuring such data in Cloud Firestore. So a possible schema might be:

Firestore-root
   |
   --- articles (collection)
        |
        --- articleId (document)
        |     |
        |     --- language: "en-US"
        |     |
        |     --- //other article properties
        |
        --- articleId (document)
              |
              --- language: "de-DE"
              |
              --- //other article properties

Using this database schema, in Android, you can simply:

  • Get all articles regardless of the language using just a CollectionReference:

    FirebaseFirestore rootRef = FirebaseFirestore.getInstance();
CollectionReference articlesRef = rootRef.collection("articles");
articlesRef.get().addOnCompleteListener(/* ... */);

  • Get all articles that correpond to a single language using a Query:

    FirebaseFirestore rootRef = FirebaseFirestore.getInstance();
Query query = rootRef.collection("articles").whereEqualTo("language", "en-US");
query.get().addOnCompleteListener(/* ... */);
