How can I delete documents using Mongoose in Node.js?

Problem

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

The above method does not appear to be effective. The records have not been destroyed.

Can someone fix?

If you don’t feel like iterating, try something else.

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

or

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

The Query returned by mongoose.model.find has a delete function.

Remove() has been deprecated in Mongoose v5.5.3. Instead, call deleteOne(), deleteMany(), or findOneAndDelete().

UPDATE: Mongoose version is now available (5.5.3)

Remove() is no longer supported; instead, use deleteOne(), deleteMany(), or bulkWrite().

You can remove a document immediately with the.remove() method as of “mongoose”: “>=2.7.1,” which appears to me to be more efficient and easy to maintain than finding the document and then removing it.

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 numerous methods for removing a document directly, such as:

For further details, see the mongoose API documentation.

docs is a collection of documents. As a result, it lacks a mongooseModel. remove() is a method that is used to delete something from a

You can iterate through the array and remove each document one by one.

Alternatively, as you appear to be searching for documents based on a (likely) unique id, use findOne instead of find.

As of version 3.8.1, this is the best for me:

MyModel.findOneAndRemove({field: 'newValue'}, function(err){...});

It also just necessitates one database call. If you don’t do anything else before the search and removal, you can use this.

remove() is no longer supported. Use deleteOne(), deleteMany(), or bulkWrite to remove items from your list ().

I use the following code.

TeleBot.deleteMany({chatID: chatID}, function (err, _) {
                if (err) {
                    return console.log(err);
                }
            });
