rxfire

问题 The goal is simple: to join two firestore queries utilizing rxjs , rxfire , and the rnfirebase react native library. I've read multiple tutorials 1, 2 on joining queries, but they all fail with different errors. //Simple test for collectionData import { collectionData } from 'rxfire/firestore'; this.myQuery = this.props.docRef.collection(`messages`).where('read', 'array-contains', this.props.me.uid) collectionData(this.myQuery, 'id').subscribe(docs => console.log(docs)) //Fails with error:

问题 I use a derived store in the code below. It feels like a strange construct because I only use the derived construct for the dynamic $session dependency and to get the normData. But not with $norm. I use $norm only once to kick off the derived store. Nevertheless it seem to work fine. But I have to renew the subscription if the $session changes. Is it possible to update the RxFire / RxJs subscription without unsubscribing first? let normDocRef = null; let normData = null; let normSubscription
