Firebase collection backup script

 If you need save some separate collection on your computer or you want backup your data outside of Firebase and default options on Google bucket. 

Working together firestore.client and tinyDb you can store your data on your computer or any other server.

Google has a well-functioning system for import / export data, but in exceptional cases it needs extra copy, then you can execute it with such a script.

        dbfile = "data/CategoryToLabelMapper.json"
        cred = credentials.Certificate("firebase-adminsdk-m3mts-d27dbb2c96.json")
        firebase_admin.initialize_app(cred)
        db = firestore.client()
        tiny = TinyDB(dbfile)
        collection = db.collection('CategoryToLabelMapper')
        docs = collection.stream()
        for doc in docs:
            dic = doc.to_dict()
             tiny.insert({doc.id: dic})

 

So, your export file will be something like this. 

 

For default solution please follow this documentation.
