Delete firestore collection

Question

I have an application with the following firestore data structure:

groups
- groupId
  - members
    - memberId

Now, when I want to delete a group, all it's members must be deleted accordingly. When I do this with a batched delete, the possibility exists that, when the client is offline, in the meanwhile new members are added so not everything will be deleted properly. How can I achieve this so everything about the group is properly removed ?

I recommend implementing this in Cloud Functions. You can either trigger that directly with a HTTP trigger, or through Cloud Firestore itself.

The latter has the advantage that the "delete" command can be sent/queued by a client while it is not connected, and will then be synchronized and executed correctly when it is next online.

Would this also work when the documents & collections are secured with an author field limiting only owners to delete their data? – jonasxd360 Jun 29 '18 at 18:28

Using the firebase-cli:

firebase firestore:delete -r /<collection path>

firebase firestore:delete --all-collections

can the firebase cli target a firestore database? I thought it can only access the firebase realtime database – Ari Nov 19 '19 at 03:16
