如何将表mongoose与nodejs连接

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 Schema = mongoose.Schema;

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

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

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

user.save()
  .then(() => {
    console.log('User saved');
  })
  .catch((error) => {
    console.error('Error saving user', error);
  });

User.find()
  .then((users) => {
    console.log('Users:', users);
  })
  .catch((error) => {
    console.error('Error finding users', error);
  });
