chat.service.ts:
getUserChats(): Observable<Chat> {
return this.auth.currUser
.pipe(
take(1),
flatMap(user => this.afs
.collection('chats', ref => {
console.log(user.uid)
return ref.where('members', 'array-contains', `/users/${user.uid}`);
})
.snapshotChanges()
.pipe(
map(actions => {
return actions.map(action => {
const data = action.payload.doc.data() as Chat;
const id = action.payload.doc.id;
return {id, ...data};
});
})
) as Observable<Chat>)
);
}
Is there a way to return the inner Observable which holds the chats from the user?
this.afs
.collection('chats', ref => {
console.log(user.uid)
return ref.where('members', 'array-contains', `/users/${user.uid}`);
})
.snapshotChanges()
.pipe(
map(actions => {
return actions.map(action => {
const data = action.payload.doc.data() as Chat;
const id = action.payload.doc.id;
return {id, ...data};
});
})
) as Observable<Chat>
In the inner observable I need to wait for the user.uid to query for the chats.

Switchmap is okay, works well with it the problem was that 'array-contains' doesnt work for DocumentReferences in Firestore
