如何在Nodejs上使用mongoose更新

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('Error connecting to MongoDB', error);
  });

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

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

User.updateOne({ name: 'John' }, { age: 30 })
  .then(() => {
    console.log('User updated successfully');
  })
  .catch((error) => {
    console.error('Error updating user', error);
  });

mongoose.disconnect()
  .then(() => {
    console.log('Disconnected from MongoDB');
  })
  .catch((error) => {
    console.error('Error disconnecting from MongoDB', error);
  });
