使用mongoose检索数据并将其放入数组中

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: String,
  age: Number
});

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

User.find({ age: { $gte: 18 } })
  .then((users) => {
    console.log(users); // 打印检索到的用户数组
  })
  .catch((error) => {
    console.error('Error retrieving users', error);
  });
