使用mongoose从多个集合中删除

const mongoose = require('mongoose');

mongoose.connect('mongodb://localhost:27017/mydatabase', { useNewUrlParser: true, useUnifiedTopology: true });

const User = mongoose.model('User', { name: String });
const Post = mongoose.model('Post', { title: String });

async function deleteData() {
  try {
    await User.deleteMany({});
    await Post.deleteMany({});
    console.log('数据删除成功！');
  } catch (error) {
    console.error('数据删除失败：', error);
  } finally {
    mongoose.disconnect();
  }
}

deleteData();

node app.js
