querySnapshot.forEach((doc) => {
doc.ref.delete();
});
this code i am using in v8 i need same thing in v9
const q = query(collection(db, `${udata.id}`));
const querySnapshot = await getDocs(q);
querySnapshot.forEach((doc) => {
// doc.data() is never undefined for query doc snapshots
console.log(doc.data());
});
already try this but this code only read data this can't allow me to delete so can some one tell me how to do it
There's a top-level function deleteDoc() to delete documents in using Modular SDK:
import { collection, query, getDocs, deleteDoc } from 'firebase/firestore';
const q = query(collection(db, `${udata.id}`));
const querySnapshot = await getDocs(q);
const deleteOps = [];
querySnapshot.forEach((doc) => {
deleteOps.push(deleteDoc(doc.ref));
});
Promise.all(deleteOps).then(() => console.log('documents deleted'))
