Mongoose - 使用多个对象更新 object 数组

Question

I have a document that contains an array of line items eg sku, description etc and i need to append a new field to it from a seperate source. This source containts the sku for matching and a second field [lineItemId]. What's the best way to update this all at once? I'd like to do it with a direct update but not sure if i need to pull the data into node, map in the lineItemId and the push the update back.

Any help would be greatly appreciated.

Collection Object in MDB

{
   _id: ....
   orderId: 1
   lineItems: [{
      sku: "sku1",
      description: "item description"
   },
   {
      sku: "sku2",
      description: "item description"
   }]
}

Second Source

[{
   sku: "sku1",
   lineItemId: "1234"
},
{
   sku: "sku2",
   lineItemId: "5678"
}
]

Desired Result

{
   _id: ....
   orderId: 1
   lineItems: [{
      sku: "sku1",
      description: "item description",
      lineItemId: "1234"
   },
   {
      sku: "sku2",
      description: "item description",
      lineItemId: "5678"
   }]
}

Use UPSERT Method

document.findOneAndUpdate({
    orderId: 1
}, { description: "item description" }, { upsert: true });
