How do I remove documents using Node.js Mongoose?

Question

FBFriendModel.find({     id: 333 }, function (err, docs) {     docs.remove(); //Remove all the documents that match! }); 

The above doesn't seem to work. The records are still there.

Can someone fix?

Answer 1

If you don't feel like iterating, try

FBFriendModel.find({ id:333 }).remove( callback ); 

or

FBFriendModel.find({ id:333 }).remove().exec(); 

mongoose.model.find returns a Query, which has a remove function.

Update for Mongoose v5.5.3 - remove() is now deprecated. Use deleteOne(), deleteMany() or findOneAndDelete() instead.

Answer 2

UPDATE: Mongoose version (5.5.3)

remove() is deprecated and you can use deleteOne(), deleteMany(), or bulkWrite() instead.

As of "mongoose": ">=2.7.1" you can remove the document directly with the .remove() method rather than finding the document and then removing it which seems to me more efficient and easy to maintain.

See example:

Model.remove({ _id: req.body.id }, function(err) {     if (!err) {             message.type = 'notification!';     }     else {             message.type = 'error';     } }); 

UPDATE:

As of mongoose 3.8.1, there are several methods that lets you remove directly a document, say:

• remove
• findByIdAndRemove
• findOneAndRemove

Refer to mongoose API docs for further information.
