For those who are using the Admin SDK with NodeJS:

import { FieldValue } from '@google-cloud/firestore'

const docData = {
  userName: 'Lucas'
  createdAt: FieldValue.serverTimestamp()
}

You could find all the external API's references here: https://firebase.google.com/docs/reference/admin/node/firebase-admin.firestore
