安装mongodb
我觉得还是用mannual install靠谱一点儿：http://docs.mongodb.org/manual/tutorial/install-mongodb-on-os-x/
启动mongodb
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": "*"
}
}
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)
})
