Mongoose - remove multiple documents in one function call

I believe what youre looking for is the $in operator:

Site.deleteMany({ userUID: uid, id: { $in: [10, 2, 3, 5]}}, function(err) {})

Documentation here: https://docs.mongodb.com/manual/reference/operator/query/in/

You can also use.

Site.remove({ userUID: uid, id: { $in: [10, 2, 3, 5]}}, function(err, response) {});
