nodejs - mongodb native find all documents

Question

Following an example from the mongodb manual for nodejs, I am finding all documents from a db as follows

mongo.Db.connect(mongoUri, function (err, db) {
    if (err) {
        console.log(err);
    } 
    else {
        db.collection('test').find().toArray(function(e, d) {
            console.log(d.length);
            db.close();
        });
    }
});

Now what I notice is that the entire set is converted to an array. As the dataset will grow, this will not be the ideal approach. Is there anyway to stream the data so it is not loaded in memory every time?

Thanks

new & fast way when compare to loop approach

const data = await db.collection('parkingSigns').find().toArray();
data // array with all the documents in the collection.
