nodejs mongodb findoneandupdate example

Example 1: mongoose findoneandupdate

// note: this uses async/await so it assumes the whole thing 
// is in an async function 

const doc = await CharacterModel.findOneAndUpdate(
  { name: 'Jon Snow' },
  { title: 'King in the North' },
  // If `new` isn't true, `findOneAndUpdate()` will return the
  // document as it was _before_ it was updated.
  { new: true }
);

doc.title; // "King in the North"

Example 2: returned value by findOneAndUpdate

const filter = { age: 17 };
const doc = { $set: { name: "Naomi" } };
const options = { new: true };

Cat.findOneAndUpdate(filter, doc, options, (err, doc) => {
    if (err) console.log("Something wrong when updating data!");
    console.log(doc);
});
