Question

I use NodeJS to insert documents in MongoDB. Using collection.insert I can insert a document into database like in this code:

// ...
collection.         


        

Answer 1

You could use async functions to get _id field automatically without manipulating data object:

async function save() {
  const data = {
    name: "John"
  }

  await db.collection('users', data )

  return data
}

Returns data:

{
  _id: '5dbff150b407cc129ab571ca',
  name: 'John'
}
