How to delete many documents from collection in MongoDB by _id in NodeJs [duplicate]

Question

I have an array of _ids, like, for example

["a12s", "33qq", "121a"]

I know, there are two method in MongoDB like deleteMany, where I can delete by specific query

  var myquery = { address: 'abc' };
  dbo.collection("customers").deleteMany(myquery, function(err, obj) {
    if (err) throw err;
  });

and deleteOne, where I could delete one specific chosen document.

I would like to delete the documents with the ids from a given array, but can't find anywhere in documentation something about this. Is it possible in MongoDB?

Answer 1

You are looking for the $in operator. It matches values in an array. You can use it in the deleteMany method filter parameter.

var ids = ["a12s", "33qq", "121a"];
var myquery = { _id: { $in: ids } };
  dbo.collection("customers").deleteMany(myquery, function(err, obj) {
    if (err) throw err;
  });
