UpdateOne returns a mongoose object and not document

Question

When running this query:

  const project = await models.Projects
    .updateOne(
      { _id: projectId },
      {
        $addToSet:
        {
          membersIds:
          {
            $each: membersIds
          },
        },
      },
    );

The response I get is the follwoing:

{ n: 1, nModified: 1, ok: 1 }

Is it possible to get an updated object instead of this mongoose data?

Answer 1

From the docs: [callback] «Function» params are (error, writeOpResult) which means that there's no way to return a document with updateOne method.

Instead of updateOne it's however possible to use findByIdAndUpdate providing lean: true option

Answer 2

ATTENTION !

I saw the responses, they are all right, BUT, pay attention to add the new option and to set it as true into the query to get the new updated document, otherwise it will return back the document before updating:

    models.Projects.findByIdAndUpdate(
    { "_id": projectId }, 
    { $addToSet:{ membersIds: { $each: membersIds }}})
   .exec()
   .then((response) => {
          console.log('document before updating =>', response);
        });

    models.Projects.findByIdAndUpdate(
        { "_id": projectId }, 
        { $addToSet:{ membersIds: { $each: membersIds }}}, 
        {new: true})
       .exec()
       .then((response) => {
              console.log('document after updating =>', response);
            });
