// const mongooseLeanDefaults = require('mongoose-lean-defaults').default;

const userSchema = new mongoose.Schema({
  name: {
    type: String,
    default: 'Bob',
  },
});
// documents will only have `name` field on database

// Later
const updatedUserSchema = new mongoose.Schema({
  name: {
    type: String,
    default: 'Bob',
  },
  country: {
    type: String,
    default: 'USA',
  },
});
// `.find().lean()` will return documents without `country` field

updatedUserSchema.plugin(mongooseLeanDefaults);

// You must pass `defaults: true` to `.lean()`
const bob = await UserModel.findOne().lean({ defaults: true });
/**

 *    _id: ...,
 *    name: 'Bob',
 *    country: 'USA'
