(question) Recursive subscription

See original GitHub issue

What would be the best approach to subscribe to any change in the tree?

My firestore document layout

rootcollection
    doc1
       subcollection11
          subdoc1
          subdoc2
    doc2
       subcollection21

For example

root level doc addition/removal/change
subcollection addition/removal/change
subdoc1 addition/removal/change

I tried

import { getFirestore } from 'redux-firestore';
getFirestore().get('/rootcollection') or getFirestore().setListeners('/rootcollection')

But it did not give me any data on subcollection level. Do i need to handle the subscription myself on client level? Or is there a better way?

There is not currently a way to check for subcollections that you don’t know the name of using Firestore’s client API, they suggest doing it within a cloud function with the Firebase Admin SDK as mentioned in this stackoverflow post and a few places in the Firebase docs.

My suggestion is to have a function handle getting the subcollection name using the admin SDK, then you can call that function from the client. Once the client has the subcollection name it can query for the data it needs. Be careful with security when using this pattern though.

Going to close since there are a few options for how to do this with functions, and it isn’t supported with the client SDK.
