javascript 如何使用猫鼬连接mongodb？

Posted 2021-05-03

const mongoose = require('mongoose')

mongoose.connect('mongodb://host_name/database_name', { useNewUrlParser: true }) // For example mongodb://localhost/users_test

mongoose.connection
  .once('open', () => {
    console.log('Good to go!')
  })
  .on('error', (error) =>{
    console.warn('Warning', error)
  })
  
  // Note that if the database not exist mongoose will create one for you
