Trying to do a bulk upsert with Mongoose. What's the cleanest way to do this?

Question

I have a collection that holds documents that contains three fields: first_name, last_name, and age. I\'m trying to figure out what query in Mongoose I can use to do a bulk

Answer 1

you can use array.map instead use for

 const result = await Model.bulkWrite(
    documents.map(document => {
        document = {
          ...document, ...{
            last_update: Date.now(),
            foo: 'bar'
          }
        }
        return {
          updateOne: {
            filter: {document_id: document.document_id}, //filter for each item
            update: {
              $set: document,//update whole document
              $inc: {version: 1}//increase version + 1
            },
            upsert: true //upsert document
          }
        }
      }
    ));
