express mongoose findoneandupdate code example

Example: 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"
