nodejs中使用monk访问mongodb

时间:2020-05-13 人气:0

安装mongodb

我觉得还是用mannual install靠谱一点儿：http:/https://img.qb5200.com/download-x/docs.mongodb.org/manual/tutorial/install-mongodb-on-os-x/

启动mongodb

$ mongod

连接mogodb

$ mongo

mongo> use monk-app

mongo> db.products.insert({"name":"apple juice", "description":"good"})

WriteResult({ "nInserted" : 1 })

mongo> db.products.find().pretty()

{
  "_id" : ObjectId("53b4cf8d5ef358e649ff1665"),
  "name" : "apple juce",
  "description" : "good"
}

在nodejs中用monk访问mongodb

$ mkdir monk-app

$ cd monk-ap

创建package.json

{
 "name": "monk-app",
 "version": "0.0.1",
 "private": true,
 "dependencies": {
  "mongodb": "*",
  "monk": "*"
 }
}

$ npm install

创建app.js

链接前面创建的数据库

var monk = require('monk')
var db = monk('localhost:27017/monk-demo')

读取数据：

var monk = require('monk')
var db = monk('localhost:27017/monk-demo')

var products = db.get('products')
  products.find({}, function(err, docs) {
   console.log(docs)
})

[ { _id: 53b4d3238cb4707ca35ab6f8,
  name: 'apple juice',
  description: 'good' } ]

插入数据：

products.insert({"name":"orange juice","description":"just so so"})

查找数据：

products.find({"name":"apple juice"}, function(err, docs) {
  console.log(docs)
})
