In MongoDB, this is the simplified structure of my account document:

    \"_id\" : ObjectId(\"5a70a60ca7fbc476caea5e59\"),
    \"templates\" :         


        

Answer 1

You can try with bulkWrite operation in mongodb

Account.bulkWrite(
  req.body.accountTemplates.map((data) => 
    ({
      updateOne: {
        filter: { _id: req.account._id, 'templates.name' : { $ne: data.name } },
        update: { $push: { templates: { $each : data } } },
        upsert : true
      }
    })
  )
})
