Detailed Problem Description
Firestore's local cache doesn't offer manual control. I'm using Realtime Database to track updates and deletes in Firestore, since snapshot listeners didn't cover all my use cases. This setup works well for new and updated documents - Firestore caches them correctly. However, when a document is deleted, Firestore doesn't remove it from the local cache, even after calling getDoc to try get Firebase to realise the document is gone.
Steps and code to reproduce issue
Enable the cache with:
export const db = initializeFirestore(app, {
localCache: persistentLocalCache({
tabManager: persistentMultipleTabManager(),
cacheSizeBytes: Infinity,
})
});
Track RTDB changes and call getDoc on the deleted doc to try get Firestore to realise it doesn't exist anymore:
const processShiftRemoval = async (snapshot: DataSnapshot) => {
const shiftId = snapshot.key;
if (!shiftId) return;
// Try force refresh the cache
await getDoc(doc(db, 'shifts', shiftId));
console.log('[ShiftContext] Processing shift removal:', shiftId);
// Update all queries to remove this shift
const queries = queryClient.getQueriesData<any[]>({ queryKey: ['shifts'] });
queries.forEach(([queryKey, oldData]) => {
if (!Array.isArray(oldData)) return;
queryClient.setQueryData(
queryKey,
(oldData: any[] = []) => oldData.filter(shift => shift.id !== shiftId)
);
});
};
onChildRemoved(pathRef, processShiftRemoval, onError);
