replicate to nested destination

Hell @anishkny,

Love this architecture and approach, using it already on my latest project!

Question - is it possible (or hard to add) the ability to target a nested property for replication?

My use-case is a “users” collection that is essentially private, and a “workspaces” collection that has an array of memberIds.

I’d like to use integrify to update a memberInfo object on workspaces, keyed by uid, with just the user’s name and avatar.

So the source is a users collection and target looks something like:

workspaces: [{
   id: "some guid",
   memberIds: ["firebaseUid1","firebaseUid2"], <--- this is currently how users are added/removed to workspaces
   memberInfoCache: {  <--- I'd like to add meta info cache to avoid complicated permissions on accessing /users/
       "firebaseUid1": { <--- the foreign key
           "photoURL": "replicated from users/firebaseUid1/photoURL",
           "name": "replicated from users/firebaseUid1/name"
       },
       ...
    }
}]

This has now landed in master. Feel free to replicate to nested destinations thus:

module.exports.replicateMasterToDetail = integrify({
  rule: 'REPLICATE_ATTRIBUTES',
  source: {
    collection: 'master',
  },
  targets: [
    {
      collection: 'subcollection',
      foreignKey: 'masterId',
      attributeMapping: {
        masterField1: 'detail1Field1',
      },
    },
    isCollectionGroup: true,    // <---- NEWLY ADDED!
  ],

I am going to hold off for now in the hopes that Firestore supports “collection group queries” eventually. That should make implementation easier/elegant. Will leave issue open for now.
