node.js使用monk访问mongodb数据库的例子,包括安装与连接mongodb、在nodejs中用monk访问mongodb,读取数据、插入数据与查数据的方法,需要的朋友参考下。
安装mongodb
mannual install安装:http://docs.mongodb.org/manual/tutorial/install-mongodb-on-os-x/
1、启动mongodb
$ mongod
2、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"
}
3、在nodejs中用monk访问mongodb
$ mkdir monk-app
$ cd monk-ap
4、创建package.json
{
"name": "monk-app",
"version": "0.0.1",
"private": true,
"dependencies": {
"mongodb": "*",
"monk": "*"
}
}
$ npm install
5、创建app.js
1)、链接前面创建的数据库
var monk =
require('monk')
var db = monk('localhost:27017/monk-demo')
2)、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' } ]
3)、插入数据:
products.insert({"name":"orange juice","description":"just so so"})
4)、查找数据:
products.find({"name":"apple juice"}, function(err, docs) {
console.log(docs)
})
