Deleting Documents

Delete operations remove documents from a collection. After deletion the indexes are automatically rebuilt to stay consistent.

deleteOne

const deleted = users.deleteOne({ name: 'David' });
// returns the deleted document or null

deleteMany

const removed = users.deleteMany({ age: { $lt: 18 } });
console.log(`Removed ${removed.length} underage users`);

To delete everything in a collection:

users.deleteMany({}); // empty filter matches all

Async Versions

await users.deleteOneAsync({ name: 'David' });
await users.deleteManyAsync({ active: false });
