nodejs中使用monk訪問mongodb

安裝mongodb

我覺得還是用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

 $ mongomongo> use monk-appmongo> 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)})
