mongodb

安裝mongodb

我認為還是用mannual install靠譜一點兒：http://docs.mongodb.org/manual/tutorial/install-mongodb-on-os-x/

啟動mongodb

$ mongod

連接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訪問mongodb

$ mkdir monk-app

$ cd monk-ap

創建package.json

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

$ npm install

創建app.js

鏈接前面創建的數據庫

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

讀取數據：

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' } ]

插入數據：

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

查找數據：

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

在mongodb創建自增id:
