如何使用mongoose获取最近添加的文档？

npm install mongoose

const mongoose = require('mongoose');

mongoose.connect('mongodb://localhost/mydatabase', { useNewUrlParser: true, useUnifiedTopology: true })
  .then(() => {
    console.log('Connected to MongoDB');
  })
  .catch((error) => {
    console.error('Failed to connect to MongoDB', error);
  });

const userSchema = new mongoose.Schema({
  name: String,
  age: Number,
  email: String
});

const User = mongoose.model('User', userSchema);

const newUser = new User({
  name: 'John Doe',
  age: 25,
  email: 'john.doe@example.com'
});

newUser.save()
  .then(() => {
    console.log('User created successfully');
  })
  .catch((error) => {
    console.error('Failed to create user', error);
  });

User.find().sort({ _id: -1 }).limit(1)
  .then((recentUser) => {
    console.log('Recently added user:', recentUser);
  })
  .catch((error) => {
    console.error('Failed to get recently added user', error);
  });
