It seems like they have added a method called getCollections() to Node.js:

firestore.doc(`/myCollection/myDocument`).getCollections().then(collections => {
  for (let collection of collections) {
    console.log(`Found collection with id: ${collection.id}`);
  }
});

This example prints out all subcollections of the document at /myCollection/myDocument
