I have an array of ids which in my case represent documents inside a collection, my goal is to remove all of those those docs inside a collection according to id's inside an array my question is should I do a for loop on the doc delete function ? or is there a function that allows you to delete multi docs according
const DeletAccount = async (sharedId: string, clientsIds: string[]) => {
const batch = writeBatch(db);
clientsIds.forEach((docId) => {
batch.delete(doc(db, 'col1', docId));
});
// Commit the batch
await batch.commit();
// Delete col2
await deleteDoc(doc(db, 'col2', sharedId));
// Delete Main doc col3
await deleteDoc(doc(db, 'col3', currentUser.uid));
}const toDelete = ['sdferwer32423asd','Pasdas34234235', 'aMNsdasd21312223232']to a preference like an array of ids in my case ?
There isn't any deleteMany() function but you can try using Batched Writes to delete upto 500 documents in a single batch.
import { writeBatch, doc } from "firebase/firestore";
const toDelete = ['sdferwer32423asd','Pasdas34234235', 'aMNsdasd21312223232']
const batch = writeBatch(db);
toDelete.forEach((docId) => {
batch.delete(doc(db, "collectionName", docId))
})
// Commit the batch
await batch.commit();
Alternatively, you can map an array of promises and then use Promise.all() as shown below:
const promises = toDelete.map((docId) => deleteDoc(doc(db, "collection", docId)))
await Promise.all(promises)
The delete() in a batch just requires a DocumentReference so you can delete documents from multiple collections as shown below:
// After forEach in previous code snippet
await batch.delete(doc(db, 'col2', sharedId));
await batch.delete(doc(db, 'col3', currentUser.uid));
// Batch commit at the end
batch.commit();
